It’s spongy moth (formerly gypsy moth) season: What to expect in 2022

While the new name still may be unfamiliar, the invasive spongy moth, formerly referred to as gypsy moth, is well known across Michigan. In its caterpillar life stage, the insect is a voracious leaf eater.

Hundreds of tiny, black caterpillars crawl on and around a fuzzy, tan egg mass on a tree trunk.Spongy moth populations were high last year across Lower Michigan, and many people are wondering whether the nuisance caterpillars will be plaguing their backyard events again in 2022. To find out, NotMISpecies webinar hosts brought together experts to share their insights on the invasive moth’s history in Michigan and the U.S. and what to expect this year.

Panelists Dr. Deborah McCullough from Michigan State University, Dr. Steven Katovich of the U.S. Department of Agriculture’s Forest Service, Susie Iott of the Michigan Department of Agriculture and Rural Development and James Wieferich of the Michigan Department of Natural Resources together represent nearly 100 years of knowledge about the pest. Following their April 14 session, they responded to participants’ questions in a written document.

Key points from the presentation and their answers to the most-asked questions about spongy moth are summarized here.

What is the forecast for 2022?

Based on recent aerial survey data, much of northern Lower Michigan has experienced two or three years of defoliation, which typically marks the end of an outbreak cycle. Egg mass surveys in the fall of 2021 confirmed that many areas in Michigan should expect a collapse of spongy moth activity in much of lower Michigan – meaning far fewer caterpillars this year. However, a few areas like Jackson County and parts of southwest Lower Michigan had large, healthy egg masses and may have high density populations again this summer.

What causes population crashes?

The last large-scale spongy moth outbreak occurred in Michigan from about 1992 to 1996. Since then, localized areas have experienced occasional outbreaks. Suppression efforts in the 1990s have continued to keep spongy moth populations largely in check while naturalizing infestations into Michigan’s forests and urban forest ecosystems.

In 1991, Entomophaga maimaiga, a fungal pathogen found to be killing spongy moth caterpillars in the northeastern states, was deployed in Michigan. This fungus proved an effective biological control, remaining in the soil from year to year and infecting spongy moth caterpillars that come in contact with the fungal spores. Moist soils help to activate the fungus, enabling spores to disperse and affect spongy moth populations. Caterpillars affected by the E. maimaiga fungus remain attached to tree trunks and hang straight down.

NPV spreads through contact between caterpillars during outbreaks, causing a population crash. To determine whether NPV is at work in a certain location, look for dead caterpillars attached to tree trunks in an upside-down “V” position.

Both the NPV virus and E. maimaiga fungus can affect the same population, and dead NPV and fungus-killed caterpillars can be on the same tree.

These natural enemies of the spongy moth are now well-established across Michigan and are actively reducing populations. To date, these pathogens typically have limited the size and length of outbreaks to a couple years, eliminating the need for spray programs.

Today, spongy moth outbreaks are cyclical, peaking approximately every seven to 10 years. In these years, the virus and the fungal disease are spread more easily through dense populations, eventually causing a crash.

Do these controls affect other species?

NPV and the fungal disease have important benefits – they are specific to spongy moth populations and do not affect people, pets or beneficial insects like pollinators or insect predators. In addition, they remain in the environment, continuing to help control spongy moth populations every year.

The spongy moth NPV pathogen (virus) is species-specific. It arrived with spongy moth and has driven population dynamics for over 150 years. In lab tests, the E. maimaiga fungus was able to infect a few other species, but this has not been observed outside the lab – the timing and behavior of spongy moth caterpillars result in fungal infection in spring. Native species either can’t be infected, are not present until later in the year or have other behavioral patterns that prevent them from becoming infected.

What about spray programs?

The State of Michigan does not have a statewide spray program. Spongy moth is a naturalized pest in Michigan now. However, a few areas have long-standing millages in place to help survey and spray residential areas when needed.

Outbreaks will continue to occur occasionally in local areas and, yes, every now and then we will have extensive outbreaks like the current one. While an outbreak is not pleasant for people in an affected area, it is rarely a problem for healthy trees and forests.

What can I do if spongy moth returns this year?

Two tan, fuzzy egg masses with small holes in them on a tree trunkFirst, check the spongy moth forecast for your neighborhood by looking for healthy egg masses now, before leaves expand. Healthy egg masses are larger than a quarter in size, tan or brownish in color and firm to the touch. Few egg masses and/or small (nickel-size) egg masses indicate the population is collapsing because the NPV pathogen is increasing. Old, no longer productive egg masses, like those in the above photo, are often abundant after an outbreak year and should not be counted. These masses are usually whiteish in color, may be falling apart and may have pin-size holes in the mass. An abundance of healthy egg masses suggests a heavy infestation of spongy moth caterpillars this season.

Before choosing a control method, remember that you will not be able to eliminate all the caterpillars – the goal is to reduce the density of caterpillars around your house.

  • Scraping: If healthy egg masses are found on trees, buildings or outdoor furniture around the home, act now, as egg masses can start hatching anytime! Use a scraper or hard, plastic card to scrape egg masses into a container of soapy water. Let them soak overnight, then bag and dispose of them. Alternately, egg masses can be placed in a fire and burned.

  • Banding: Cut a band of burlap 18 inches wide and long enough to go around the tree trunk and overlap a bit. Tie a string around the center of the band to make a two-layered skirt around the trunk. When caterpillars climb trees daily to feed, they will get caught in the band. Scrape them into a bucket of soapy water to kill them.
  • Spraying: To address an infestation in a handful of individual trees, homeowners can purchase a spray containing Bacillus thuringiensis var. kurstaki, a bacterium that naturally occurs in the soil but can be lethal to certain caterpillars and moths. The best time to spray is when caterpillars are small, usually mid-May through early June. Be sure to choose an Environmental Protection Agency-registered pesticide and apply it according to label directions. Remember, there is no good reason to spray woodlots or forested areas. Healthy trees and forests can withstand periodic infestations.

Gov. Whitmer Proclaims Small Business Week in Michigan, Encourages Michiganders to Support Local Businesses 

 

LANSING, Mich. – Today, Governor Whitmer proclaimed May 1 – 7 as Small Business Week in Michigan, celebrating the resiliency and contributions of small businesses and entrepreneurs.

 

“Happy Small Business Week! Small businesses are anchors of our communities—they create jobs, build more vibrant cities and towns, and generate prosperity for Michiganders in every region of our great state,” said Governor Whitmer. ”Michigan’s small businesses are tough. They have been resilient and strong over the last couple of years and we should come together to celebrate them and their invaluable contributions to our state by shopping local not only this week, but every week. I will work with anyone to ensure that small businesses have the resources they need to succeed. Right now, our unemployment rate is 4.4% and we’ve added 174,000 year over year. Let’s keep working together to grow Michigan’s economy, create more good-paying jobs, and invest in small businesses in every county.”

 

According to the U.S. Small Business Administration, small businesses comprise more than 98 percent of Michigan businesses and employ half of Michigan workers. For every $100 spent at a local business, roughly $68 stays in the local economy, allowing business and job growth.

 

In addition, according to the Michigan Retailers Association, one in five Michigan jobs are in the retail industry. In 2020, Michigan residents sent $23.7 billion to out-of-state retailers. If only one in 10 out-of-state purchases were switched to local stores, Michigan would gain $1.9 billion in increased economic activity, creating 14,000 new jobs.

 

Governor Whitmer is committed to supporting small businesses as Michigan continues growing its economy. Recently, the governor laid out a $2.1 billion proposal to grow Michigan’s middle class, support small businesses, and invest in communities. As Michigan’s economy grows, bolstered by a multi-billion-dollar surplus, and increasing momentum, Governor Whitmer’s proposals will tackle underlying issues faced by small businesses and make bold investments to create economic prosperity for all.

 

  • Laid out MI New Economy, a $2.1 billion plan to grow Michigan’s middle class, support small businesses, and invest in communities.
  • $500 million to build on the Michigan Mainstreet Initiative, which offers grants to restaurants, place-based businesses, and microenterprises with further dollars to attract more start-ups.
  • $200 million to create a more conducive business environment for high-tech, high-growth start-ups and create jobs of the future in Michigan.
  • Added 220,000 jobs in 2021, drove down unemployment and took Michigan from a projected $3 billion deficit to a $7 billion surplus.
  • Enacted a bipartisan tax cut for small businesses, enabling them to grow and create jobs.
  • Signed an executive directive to increase state procurement and contracts with small and geographically disadvantaged businesses.

Michigan releases 2022 Eat Safe Fish Guides to help
residents learn about and plan for local fish consumption
Updates include a ‘Do Not Eat’ fish advisory for bluegill and sunfish in parts of
Rouge River and lifting of ‘Do Not Eat’ fish advisory for parts of Huron River

LANSING, Mich. – The Michigan Department of Health and Human Services (MDHHS) has released the 2022 regional Eat Safe Fish Guides. These guides can help Michiganders plan their fish consumption to minimize exposure to chemicals that can build up in fish, while still getting all the health benefits of eating fish.

The regional Eat Safe Fish Guides provide guidelines for eating locally caught fish. Guidelines are based on levels of chemicals found in the portions of fish that people eat – typically the filets. Test results from the MDHHS Bureau of Laboratories are used to determine what is safe for people to eat over the long-term. There are many health benefits to eating fish and the Eat Safe Fish Guides help individuals choose the fish that are best for them and their families.

One update to the Eat Safe Fish Southeast Michigan Regional Guide is a ‘Do Not Eat’ advisory for bluegill and sunfish caught in the Lower Branch of the Rouge River and the Main Branch of the Rouge River from the Ford Estate Dam to the Detroit River. Bluegill and sunfish were collected from these parts of the river in 2021 and analyzed for harmful contaminants. Due to high levels of perfluorooctane sulfonate (PFOS), a type of per- and polyfluoroalkyl substance (PFAS), MDHHS recommends that people avoid eating bluegill and sunfish from this stretch of the Rouge River.

Other species of fish collected in 2019 and 2021 from this same stretch of the river were found to be contaminated with PFOS, but not at levels that call for a ‘Do Not Eat’ advisory. The Michigan Department of Environment, Great Lakes, and Energy is continuing to investigate possible sources of this PFOS contamination. There is also historical PCB contamination for this stretch of the river. Consumption guidelines for all other species of fish in this stretch of the Rouge River can be found in the Eat Safe Fish Southeast Michigan Regional Guide.

Another update includes the lifting of the ‘Do Not Eat’ fish advisory for most fish species from a specific stretch of the Huron River due to recent fish filet data. The advisory is lifted for the stretch of the Huron River from where it crosses I-275 in Wayne County to the river mouth at Lake Erie, including the Flat Rock impoundment.

Although the ‘Do Not Eat’ fish advisory has been lifted for most fish species from this stretch of the Huron River, fish consumption guidelines are still in place for the following species:

  • Bluegill and sunfish have a recommended eight MI Servings per month due to PFOS.
  • Carp have a recommended ‘Limited’ category for fish less than 28” and a recommended ‘Do Not Eat’ category for fish greater than 28” due to polychlorinated biphenyls (PCBs) and dioxins. Fish with a ‘Limited’ category should not be eaten by people under the age of 15, those who have health problems like cancer or diabetes, those who may have children in the next several years, those who are pregnant or those who are breastfeeding. People who do not fall under any of those categories are recommended to limit their consumption to one to two servings each year.
  • Catfish have a recommended one MI Serving per month due to PCBs.
  • Largemouth and smallmouth bass have a recommended four MI Servings per month due to PCBs and mercury.
  • Rock bass still have a recommended ‘Do Not Eat’ advisory due to PFOS.
  • For other fish species, refer to the statewide guidelines.

The ‘Do Not Eat’ fish advisory remains in effect for the Huron River from where the river crosses N. Wixom Road in Oakland County to where the river crosses I-275. This includes: Norton Creek (Oakland County), Hubbell Pond also known as Mill Pond (Oakland County), Kent Lake (Oakland County), Ore Lake (Livingston County), Strawberry & Zukey Lakes (Livingston County), Gallagher Lake (Livingston County), Loon Lake (Livingston County), Whitewood Lakes (Livingston County), Base Line & Portage Lakes (Livingston/Washtenaw County line), Barton Pond (Washtenaw County), Geddes Pond (Washtenaw County), Argo Pond (Washtenaw County), Ford Lake (Washtenaw County), and Belleville Lake (Wayne County).

Unlike the Michigan Department of Natural Resource’s Michigan Fishing Guidethe MDHHS Eat Safe Fish guidelines are not laws or regulations, and no one is required to follow them. Instead, the guides are a free resource for those who would like information about which fish, and how much of those fish, are healthy to eat from various bodies of water across the state.

Chemicals in fish are a worldwide problem that is not limited to Michigan and other Great Lakes states. The chemicals most commonly found in fish are mercury and PCBs. However, PFAS, including PFOS, have also been found in fish from certain bodies of water in Michigan.

It is important to note that fish from some areas in Michigan are more contaminated than others. By using the Eat Safe Fish Guides, Michigan consumers can be confident that they are making informed choices about eating the fish they catch from their local lake or river.

In addition to the Eat Safe Fish Guides, MDHHS also produces the Buy Safe Fish Guide to help residents choose seafood that is lower in mercury from local grocery stores, fish markets and restaurants. The Eat Safe Fish Guides and Buy Safe Fish Guide are available online at Michigan.gov/eatsafefish.

EGLE’s Office of the Clean Water Public Advocate promotes Drinking Water Week

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) kicks off Drinking Water Week today, which also include Private Residential Awareness Day on Tuesday, May 3. The purpose of this weeklong event is to recognize the vital role drinking water plays in daily life and the critical infrastructure required to carry it to our homes.

EGLE’s Office of the Clean Water Public Advocate (OCWPA) will use this week to educate the public on their drinking water and provide tips that residents can use to help ensure they have quality tap water by connecting residents to state drinking water resources. Every Michigander should be equipped with knowledge that helps keep their drinking water healthy.

“There are actions all of us can take to support healthy drinking water from protecting the source to getting the water moving in our home plumbing.” Said Kris Donaldson, EGLE’s Clean Water Public Advocate.

The week begins with a primer on drinking water that covers where it comes from and how it gets to your home or place of work. Knowing your water supply is key to learning about your water quality and determining who to contact with concerns. Depending on your water supply, your local health department or water supplier is likely your best resources for answering questions about your water. Residents can also report drinking water concerns online using EGLE’s Drinking Water Concern System.

Tips to reduce your risk of exposure to lead in drinking water, which is a particular concern in homes with older plumbing or those served by lead service lines, are also covered.

Private Residential Awareness Day on Tuesday will focus on the more than one million private wells in Michigan that provide drinking water to over 2.6 million Michigan people statewide. Drinking Water Week highlights important resources about well maintenance and testing found on the Michigan Department of Health and Human Service’s (MDHHS) Care for MiWell (URL: Michigan.gov/Envirohealth) website.

Drinking Water Week also brings attention to the critical role water infrastructure plays in getting healthy drinking water to our tap. The Michigan legislature this year approved a major supplemental appropriation that includes over $1.8 billion in funding to EGLE for clean water and drinking water infrastructure projects.

Gov. Whitmer Announces State to Expand Medicaid Coverage for Moms & Babies

New approval expands coverage to full 12-month postpartum period, a key competent of Governor Whitmer’s Healthy Moms, Healthy Babies initiative

 

LANSING, Mich. – Coinciding with the beginning of Maternal Mental Health Awareness Month, Governor Gretchen Whitmer today announced that the state’s request to expand Medicaid coverage for a full 12-month postpartum period to ensure the health and well-being of moms and babies across Michigan had been approved by the Centers for Medicare and Medicaid Services (CMS). This expansion is a critical component to the governor’s Healthy Moms, Healthy Babies initiative.

 

“As a mom of two, I know firsthand how vital it is for every mom to have access to high-quality, affordable healthcare to care for herself and her new baby,” said Governor Gretchen Whitmer. “By extending these critical, 12-month postpartum benefits, we can improve long-term outcomes for moms and babies and close health disparities. We will continue working together to ensure every family can thrive with access to behavioral health services, screenings, and treatments to lead healthy and successful lives.”

 

“I have long supported legislation to make this extension of postpartum care permanent, and I am so grateful to have an ally in this fight in Governor Whitmer,” Sen. Winnie Brinks (D-Grand Rapids) said. “New moms and their health care providers agree that current standards of postpartum care are antiquated, especially in communities where health disparities exist. This is a huge step towards ensuring every new mom gets the care and support she needs, and we know healthy moms have healthy babies, laying the foundation for a healthy life.”

 

Under existing requirements, many Medicaid enrollees receive coverage through the end of the month in which their 60-day postpartum period ends. Maintaining Medicaid coverage for a full year provides access to critical health and dental services during the first year after pregnancy, which can help to address persistent health disparities. The approximately $20 million budgeted for this expansion will benefit an estimated 35,000 pregnant and postpartum people in Michigan annually.

 

“Being able to ensure continuity of care for Michigan moms and babies is critical to reducing preventable deaths and will lead to better long-term health outcomes for new parents and newborns,” said Elizabeth Hertel, Director of the Michigan Department of Health and Human Services. “Extending Medicaid postpartum coverage will assist the state in its continued efforts to improve access to care for all Michigan families and equitable health outcomes.”

 

This extension promotes access to critical behavioral health services that can reduce pregnancy-related deaths and severe maternal morbidity and improve continuity of care for chronic conditions such as diabetes, hypertension, cardiac conditions, substance use disorder and depression. Extending postpartum eligibility will provide increased opportunities for beneficiaries to complete postpartum depression screening and receive referrals to services and supports for needed treatment. Beneficiaries will have similar access to supports and treatment for substance use disorder conditions if needed as well.

 

Access to high quality health care services is a critical component of statewide efforts in addressing maternal morbidity and mortality rates in Michigan. As of January 2018, Michigan’s Maternal Mortality Surveillance (MMMS) Committee found that approximately 50% of maternal deaths in Michigan were preventable.

 

One of the possible prevention measures identified by the MMMS committee is access to family planning and other medical health care services. Additionally, among pregnancy-related deaths in Michigan the committee found persistent racial disparities.

 

Current Medicaid recipients do not need to take any actions to receive the extended coverage. It will be extended automatically to 12 months past their reported delivery date.
