Celebrating 30 years of IPM

30-Year_coverProgram report. You see the words; what comes to mind? Jargon. Puffery. In a word? Boring.

But at NYS IPM, we’ve made a practice of telling stories — stories that take you on the farm, in the greenhouse, to the school cafeteria. Now we’ve taken the essence of all our annual reports spanning 30 years — and crafted an anniversary report that celebrates three decades of integrated pest management in New York.

Yes, our mission has changed over time. But the themes are the same. Thirty years ago, people cared about the food they ate. The fields they walked in. The schools their kids went to. Best ways to prevent pests, whether on their crops or in their gardens. A healthy environment for themselves and their families.

They still do. And we’re still here them — for you, the reader. As relevant as ever. Check us out here.

BTW … the main thing to remember with this pdf? The middle part with the postcards and the map — that’s a foldout that takes you on an IPM road trip that highlights three-score stories standing for the hundreds we didn’t have space to tell. No way can a pdf do it justice.

To order a printed copy please contact the IPM Program office.

Cornell Forest Entomologist Tackles Tough Pests, Earns Excellence in IPM Award

ITHACA, NY. November 3, 2015: Emerald ash borer. Hemlock woolly adelgid. These pests pack a one-two punch for New York’s 18 million acres of forestland. Now, for his hard work and dedication in slowing the spread of these formidable pests, Mark Whitmore — a forest entomologist at Cornell University — has received an Excellence in IPM award from the New York State Integrated Pest Management Program (NYS IPM) at Cornell University.

Indeed, Whitmore was the “Paul Revere” of sneaky invasive pests such as emerald ash borer and hemlock wooly adelgid long before they crossed the state line, says Brian Skinner, senior arborist with National Grid, an electric transmission distributor in New York and New England. Like other transmission companies, National Grid is deeply concerned by the potential damage that borer-killed ash trees could cause our electric system.

“Mark has been an avid and welcomed presenter to those of us in New York’s utility vegetation management industry,” Skinner says. “Often addressing small crowds with NIMBY attitudes, he offers a hope of preservation. He never gives up, becomes despondent or changes his message.”

Dr. Hilary Lambert, executive director of the Cayuga Lake Watershed Network and well aware of the value of hemlock trees to watershed health, couldn’t agree more. “Mark has been ready to help the public at every step of the way in developing outreach materials, volunteer events, and teams to monitor for the adelgid, not only in the Cayuga Lake basin but widely across the state.” Lambert says. “His emphasis on effective solutions, not despairing hand-wringing, has been especially welcome.”

Whitmore’s work is built around classic IPM techniques: prevention and monitoring, biological controls — the predators and parasites of these two pests — and, if needed, low-toxicity pesticides. “Mark’s meticulous research brings together all the strengths of IPM; of truly integrated pest management,” says Jennifer Grant, director of NYS IPM. But it’s his passion for his work that really makes the difference, Grant notes. “Whether it’s volunteer citizen-science groups, utility companies, or the New York State Department of Environmental Conservation, people look to Mark for the information and expertise they need,” Grant says. “He speaks for the trees.”

Whitmore received his award at on November 3 at Cornell University’s Ag In-Service training before dozens of his peers.

Comments Off on If you’re not monitoring, you’re not performing IPM.

If you’re not monitoring, you’re not performing IPM.

Why? To start, let’s consider the distinction between an inspection and monitoring. An inspection is a view of pest activity at that moment in time. But what if pests are only active at night? Or on weekends when the building is quiet? Thus, monitoring is a record of pest activity in the times that you are not present.

Integrated Pest Management, or IPM, is a decision making process that uses information about pest populations to decide how to manage them. Monitoring is a critical step in IPM programs that offers valuable insights:

1. Species Identification: insect monitors intercept pests, allowing a trained professional to identify them. In turn, identification provides information about preferred harborage, food and water sources.

2. Early Detection: monitors can intercept pests that are present at low levels, and can help identify a problem before it gets out of hand.

3. Directionality: monitors can provide information about pest directionality: where are they coming from [harborage] and where they are going [food locations]. Monitors might also provide clues about non-obvious pathways, such as overhead areas (Figure 1).


Fig. 1. This firebrat likely fell onto the monitor from above.

4. Age of Population: rodent bait stations can contain informative evidence (Figure 2). Are droppings all one size, or are they mixed sizes, suggesting the presence of different age groups? Are droppings black, meaning that they are visiting the station for the first time, or are some droppings the color of the bait, suggesting multiple feedings?

2011.2.23 (2)

Fig. 2. Mixed large and small droppings suggest adult and juvenile feeding; mostly black droppings suggest this is the rodents first feeding.

Parasitoids, predators and secondary pests can also tell you about the age of the infestation (Figure 3). Ensign wasps are egg-case parasitoids of American cockroaches. Their presence suggests that the cockroaches are actively reproducing nearby, whereas secondary pests may indicate the presence of old bait or pest carcasses.

5. Proximity to Harborage: juvenile pests, including rodents and cockroaches, stay close the harborage. Intercepting them on monitors can narrow your search to nearby areas for identifying the harborage (Figure 4).

6. Management Efforts: some monitors might contain evidence about recent control efforts (Figure 4). Finding German cockroaches with crinkled wings is a sign that they have been treated with an insect growth regulator. But what if you didn’t apply this kind of product? Perhaps the cockroaches are coming from a neighboring area.

Effective monitoring programs provide good coverage of pest vulnerable areas. The location of monitoring devices are recorded on a facility map, and a pest catch log records the number of pests caught on each monitor. These specifications allow the pest professional to collect enough information to determine if a treatment is needed, where to focus efforts and what treatment should be applied.

Comments Off on Lawn IPM – Reducing Stress

Lawn IPM – Reducing Stress

“It’s so dry the trees are bribing the dogs.” ― Charles Martin, Chasing Fireflies

While drought stress might not seem like an IPM issue, it can definitely impact how your grass will respond to pests, both current and future. As Pat Vittum, Turf Entomologist at UMass, tells her students, “Turf can take one or two stresses, but not three or four.” How can you reduce stress during these dry times?

Yes, it is dry out there.
Yes, it is dry out there.
Hold off on fertilizers…

at least until the weather flips to cooler temperatures and you can water it in, either by timing it before predicted rain or through irrigation. Fall fertilization will help to increase turf density by helping the turf produce more tillers, rhizones, and stolons and encourage shoot growth, but only if it can reach the root zone. Look to apply one pound of nitrogen per 1,000 ft2, plus other nutrients recommended by a soil test.

Baby it

Now is not the time to park on the grass, host a neighborhood  pickup flag football game, or allow the kids to set up a bike ramp.

Mow high

Set your mower to its highest setting. The longer the leaf blades, the deeper the roots, providing a buffer against drought, diseases, and insect damage.

Make sure those blades are sharp.

If you haven’t yet sharpened your blades, don’t wait any longer. Dull blades shred rather than cut, allowing more moisture loss and increase turf stress. You can find information on blade sharpening here.

Wait to mow

Unless you have irrigation, your lawn is likely not growing. No growth, no need to mow. If storms drop some needed moisture and the grass takes off, wait until a cooler time of the day to mow. Do not, however, wait too long. If you end up leaving clumps of clippings, they can block out the sun and seal in the moisture, leaving the turf susceptible to humidity loving diseases. Once it is growing, mowing should be conducted often, twice a week or more. Mowing increases shoot density by increasing tillering (stems that develop from the crown of the parent plant). The more tillers, the fuller your lawn, leaving less room for weeds.

For up-to-date information on turfgrass conditions, listen to Cornell’s Frank Rossi’s weekly podcast. Grass specific weather information, including when and how much to water, can be found at ForeCast: Weather for the Turf Industry.

Are you ready for fall invaders?

September 10, 2015 by Matt Frye

Insects exhibit a variety of behaviors or adaptations that help them to survive the harsh conditions of winter. One that can be quite frustrating to homeowners belongs to the the group of insects we call “overwintering pests.” These organisms survive winter by taking refuge in South or West facing cracks and crevices, which maximizes exposure to the warm sun and buffers them from wind and freezing cold. While trees and rocky hillsides provide overwintering sites in nature, man-made structures that now dominate the landscape are perfectly acceptable to these insects.

The Culprits. Multicolored Asian ladybird beetles, boxelder bugs, western conifer seed bugs, cluster flies, and the brown marmorated stink bug are common fall invaders in the Northeast. Some of these insects are exotic invasive species that were accidentally introduced to the US, such as the stink bug, which was first identified from samples collected in Allentown, Pennsylvania in the 1990’s. A new insect, the kudzu bug, was introduced to Georgia in the early 2000’s and may soon invade homes in the Northeast.

Can they be Stopped? If overwintering pests gain access to buildings through cracks and crevices, it seems reasonable that sealing these openings will keep pests out. While no formal research has tested this hypothesis, a recent grant awarded by the Pest Management Foundation will evaluate the effectiveness of exclusion as a technique to keep stink bugs and other overwintering pests out of homes (Note: the Pest Management Foundation is the education, research and training arm of the National Pest Management Association). In the mean time, below are some common recommendations to dealing with overwintering pests:

  • Using an appropriate sealant labeled for doors and windows, seal exterior gaps that could allow entry into the home. Remember to inspect locations where wires, pipes, and other utility lines enter the structure, especially on the South and West facing side of buildings.

Look for and seal gaps around window and door frames.

Repair torn screens

  • Make sure that screens are tight fitting in the window frame, and they do not have any tears.
  • Keep attic doors and fold-down stairs closed during winter months. Insects can enter attic spaces through soffits, later entering the livable space when they are attracted to lights and heat.
  • Flues should be closed in the fireplace when it is not in use.

Trapping Pests. On warm winter days, stink bugs and other overwintering pests may become active. During the day, they can be found at windows, while at night they may fly towards artificial lights from the television, computer or lamps. One indoor trap type that is easy to make and effective is a pan trap. Read more about this device here: Stink bugs beware! Homemade stink bug traps squash store-bought models, Virginia Tech researchers find.

Everything Wants to Prepare for Winter


A Gray Squirrel checks out a possible winter home.

Although summer heat is predicted for New York State through at least the Labor Day weekend, signs of the inevitable change of seasons are upon us. The daylight hours are becoming shorter, territorial singing by birds has decreased greatly, and many animals, including tree squirrels, begin preparing for the long, cold months of winter. In addition to their well-known behavior of caching nuts during autumn, squirrels look for protective sites for over-wintering. Often, these locations include the attics and walls of houses and other buildings. It is not unusual to have 8, 10, or more squirrels over-wintering in a building. Structural damage caused by the animals’ chewing can be significant. There is also the possibility of infestations of parasites associated with the animals, and at least the potential risk of disease transmission.

As with the management of any pest situation, prevention is preferred over seeking to rectify a well-established problem. For squirrels, this would include an inspection of the building exterior looking for potential entry sites and routes of access. August and early September are optimum times for inspecting. This is ladder work so safety is a very important consideration. Consult ladder safety sites such as the American Ladder Institute.

Cage trapping is a common tactic of many homeowners and businesses in seeking to rectify a squirrel or other wild animal problem. The animals are then transported off-site. However, this is illegal in New York State, and many other places, without a state-issued permit. Read Dealing With Wildlife and the New York Laws That Protect Them for a synopsis of the legal framework for dealing with nuisance wildlife.

Individuals who operate under such a permit are referred to as Nuisance Wildlife Control Operators or, simply, Wildlife Control Operators. These individuals have passed a comprehensive exam on solving wildlife problems and have the experience and equipment to address nuisance wildlife and wildlife damage situations. For names of permit holders, contact your regional office of the New York State Department of Environmental Conservation. Another source is the NYS Wildlife Management Association, the state trade group for wildlife control operators.
