CICADAS and CICADA KILLERS… subtitled… “Is This A Murder Hornet?”

2020 is proving to be a…ahem…wild year.  The unusual, big eyed creatures we know as the PERIODICAL CICADA or CYCLICAL CICADA–particularly those known as Brood IX by U.S. Entomologists–made their debut in the late spring of 2020.  Male cicadas make a lot of noise to attract a mate and in big brood years, that can be a lot of noise. (NPR’s CICADA article may be of interest!)

While big cicada emergence years like this one and the one in 2013 are noteworthy, that doesn’t mean that cicadas can’t be found each year. Otherwise, the impressive CICADA KILLER WASP would have a long wait. Understanding the difference between three large insects of the hornet and wasps family has never been more important: 1) cicada killer wasp, 2) European hornet, and 3) Asian giant hornet.

As of August, 2020, there are NO ASIAN GIANT HORNETS in the northeast.  What you might see are Cicada Killers or European Hornets, so we’re back with more photos. (see our blog post  Dog Day Cicadas and the Wasps that do them in!)

Below: CICADA KILLER WASP: Earlier this year, ‘murder hornets’ became a big topic. To bring some wisdom to the discussion, we provided some facts (see blog post: Asian Giant Hornets). Now, with August being the prime time to see cicada killer wasps and European hornets in action, murder hornets are news again, and still not in NY!

Please don’t kill these large but very low risk cicada killer wasps.

Back to School – Keeping the Rodents Outside

We should have little trouble with vermin if builders would hear and understand the ‘language’ of vermin and do a better job in eliminating their entrances and hiding place.” – Hugo Hartnak, 1939

photo of Bobby Corrigan wearing a hard hat, holding a clipboard in one hand and a flashlight in the other pointing out a rusted wall grid plate with a hole large enough for a rat to fit through.

For Bobby Corrigan, pest management is a passion. Called upon for his expertise across the country, we are honored to include him in our conference.

Pests enter school buildings in one of two ways: they are transported in by students, staff, or delivery truck or they make their way in from the outside. The School IPM 2020: Where We’ve Been and What’s Next virtual conference will focus on the first mode, but we will also include information on the second with tips, and a tool, to help with exclusion – or keeping pests out of buildings. Dr. Bobby Corrigan, co-founder of the first Scientific Coalition on Pest Exclusion, will join us to discuss rodent vulnerable areas.

People are Talking About Gypsy Moths

ADAPTED FROM A GREAT ONLINE RESOURCE!!  THE FOREST PEST HANDBOOK is a publication of the NYSIPM Program and New York State Department of Agriculture and Markets, authored by Elizabeth Lamb and Jennifer Stengle Lerner.

graphic is a screenshot of the cover of the FOREST PEST HANDBOOK showing a tree canopy.

People around the state are noticing gypsy moths…

Specifically European Gypsy moth — Lymantria dispar dispar

(Note: The Asian gypsy moth is a concern in some parts of the United States but is NOT currently an invasive pest in New York.)

The European gypsy moth was accidentally introduced into Massachusetts in l869. By 1902 this pest was widespread in the New England states, eastern New York, and regions of New Jersey.

Generally from late July through early September, female moths will lay egg masses on bark, firewood, exterior of campers and outdoor equipment and be easily transported. The gypsy moth is an important insect pest of forest and shade trees in the eastern United States. Heavy defoliation by the larval stage of this pest causes stress to infested host plants. Adult male moths are dark buff and fly readily during the day. Females are white with black, wavy markings, have robust abdomens, wingspans up to 2 in ches (50 mm) but do not fly.

Egg masses may be found on trees, rocks and other surfaces from early April through mid May. They are light tan, and the eggs inside are black and pellet like. Each mass may contain 400-600 eggs.

The larval stage (caterpillar) is hairy, and a mature larva is 2-2.5 inches (50-65 mm) long with a yellow and black head. Behind the head on the thorax and abdomen are five pairs of blue spots (tubercles) followed by six pairs of brick red spots. Young larvae feed on foliage and remain on host plants night and day.  Around mid April, larvae emerge from egg masses. In late May, when about half-grown, larvae change their behavior and usually feed in the trees at night, and move down to seek shelter in bark crevices or other protected sites during the day. Larvae molt numerous times until full grown at 2-2.5 inches.  Larval feeding is THE STAGE WHEN TREE DAMAGE OCCURS. Feeding on leaves can last for up to six weeks. Look for defoliation of host trees. You may also hear frass dropping from trees (believe it or not…), though that may come from feeding by other species of caterpillars. Caterpillars may move down into bark crevices during daytime and return to canopy feed at night.

The pupal stage is dark reddish-brown and is held in place to some object by small strands of silk. Pupation is generally in July or early August. This year, adults have been seen in July.

Borrowing from our friends over at University of Illinois Extension.

Which tree species does this pest damage? PLENTY!

Alder (Alnus spp.) Aspen (Populus spp.) Gray birch (Betula populifolia) White birch (B. papyrifera) Hawthorn (Crateagus spp.) Larch (Larix spp.) Linden (Tilia spp.) Mountain ash (Sorbus spp.) Oaks (Quercus spp)Lombardy poplar (Populus nigra) Willows (Salix spp.) Witch-hazel (Hamamelis spp.) Beech (Fagus spp.) Red cedar (Juniperus spp.) Chestnut (Castanea spp.) Hemlock (Tsuga spp.) Plum (Prunus spp.) Pine (Pinus spp.)

What to do? The time to act is/was when egg masses can be found and destroyed  (fall, winter and spring), or when young larvae can be reduced in numbers. If you’ve seen a lot of adult moths, you might want to take a look for egg masses on your trees in the fall and winter.

Mysterious package? Update!

The story will be developing quickly. Here is the July 27 update from the New York State Department of Agriculture and Markets:Banner box stating July 27, 2020 Albany, NY Statement by New York State Commissioner of Agriculture Richard A. Ball on Unsolicited, Mislabeled Packages of Seeds Being Sent From China

“Our office has received questions from a few New Yorkers who have received unsolicited packages allegedly sent from China that are marked as containing jewelry (or other items) but which actually contain plant seeds. Similar packages have been received in other states and the United States Department of Agriculture is investigating. People who receive seeds should not plant or handle the seeds. They should store them safely in a place children and pets cannot access and email USDA immediately at erich.l.glasgow@usda.gov for instructions. Seeds imported into the United States are rigorously tested to ensure quality and prevent introduction of invasive species, insects and diseases. We will continue to monitor this issue and will pass along guidance as it is received from USDA.”

*Note to newsrooms: Please advise consumers to email USDA with their full names and telephone numbers, pictures of the package and any other relevant information.

Back to School – Humans Only!

A picture of a school with a banner that says "School is Open Humans Only" with a bedbug, cockroach, tick looking at the sign. The tick is holding a mouse pull toy and the cockroach is holding a coronavirus shaped balloon.Schools across the world are having conversations about safely sending teachers, students, and the rest of the school staff back for face-to-face education during a global pandemic. These are vitally important discussions and plans need to adapt to new information. And this focus on school health and safety also provides an ideal, if unanticipated, backdrop for our rescheduled annual conference – School IPM 2020: Where We’ve Been and What’s Next.

Covid-19 is an excellent example of a community issue that cannot be handled by school personnel alone. We have all been called to support the health of the community through social distancing, wearing masks, and handwashing. Our conference will focus on community-wide pest issues such as German cockroaches and bedbugs. There is simply no way for schools to prevent these insects from being reintroduced by students, school staff, and delivery trucks. How then, as a community, can we address these issues before they breach the school walls? And avoid the subsequent calls by some to close the building for pesticide applications?

The penultimate hitchhiker, bed bugs need to be dealt with at a community level.

Please join us on the mornings of August 11 and 18 as we hear from community and agency leaders – and you! – about efforts to provide healthy learning and work environments. We welcome your experiences and ideas as we use this momentum to address school pest issues now and into the future.

Drought worsens in Northern New York

Severe drought has developed in northern New York along the St. Lawrence Seaway as of 21 July, according to the National Drought Mitigation Center. Conditions throughout the northeast and New England have generally become drier in recent weeks but an extended pattern of particularly low rainfall along the northern New York border is cause for growing concern. Click here for full list of impacted areas are listed alphabetically by county and township.

SIGN UP FOR OUR CONFERENCE: School IPM 2020: Where We’ve Been and What’s Next

A Virtual Two Half-Day Conference

When: Mornings of August 11 & 18, 2020

Where: We will be connecting via Zoom.

How: Click Here to Register

Cost: $15 per person or $25 per school district

PESTICIDE APPLICATOR CREDITS AVAILABLE:

NYSIPM Conference 2020 pesticide recertification credits

NYS Pesticide Applicator recertification credits have been awarded for the following categories: Core, 3A, 3B, 7A, 7F, and 8. Individuals seeking credits will need to submit their applicator ID numbers when pre-registering. Further instructions will be sent upon pre-registering.

Despite decades of promoting school integrated pest management (IPM), bed bugs, cockroaches, lice, and mice continue to be a problem in schools. Part of the issue is lack of implementation of proven IPM techniques such as exclusion. Part of the issue is that some pests, like bed bugs, German cockroaches and lice arrive in backpacks, delivered supplies, and directly on students and staff. While schools often have plans in place to address these pests when they are discovered, it will take a wider community effort to prevent their introductions.

The Sixth Annual NYS IPM conference brings together a wide range of speakers to address and discuss the status of school IPM adoption and where we need to go in the future. If you or your family is impacted by pests or pest management on and off school property, this virtual conference is for you.

Alejandro A. Calixto, our new NYS IPM Program director, will be introducing the conference with remarks on “Perceptions of IPM and Today’s Social Climate.”

Our keynote speaker, Lorraine Maxwell, will discuss “Healthy Environments for Learning”. Her research has found that school building conditions, which include conducive conditions for pests as well as the presence of pests, impact the school’s social climate, which directly impacts student performance.
