International Plant Protection Convention approves standards on pests

The body charged with keeping global trade in plants and plant products safe has adopted several new phytosanitary standards aimed at preventing destructive agricultural and environmental pests from jumping borders and spreading internationally.

The standardized norms developed by the International  Plant Protection Convention (IPPC) cover a range of strategies and techniques used to prevent the introduction and spread of plant diseases and pests to new environments, thereby avoiding their often-devastating impacts on biodiversity, food security and trade.

University of Kentucky study combines outdoor exercise with tree health observations

by Katie Pratt, University of Kentucky

University of Kentucky researchers are looking for Lexingtonians interested in improving their health while gaining a greater awareness of their natural environment for a six-week research pilot project.

The project, titled “Healthy Trees-Healthy People,” gets participants out into two Lexington parks to walk and assess the health of selected trees. During the study, they will complete a daily log of their physical activity and tree health observations on designated trails at either Kirklevington Park or Harrods Hill Park. Depending on the park, routes are just under a half-mile and a mile. Continue reading

APHIS Adds Kane, Kendall, LaSalle, and Will Counties, Illinois, to the Gypsy Moth (Lymantria dispar) Regulated Area

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is adding Kane, Kendall, LaSalle, and Will Counties in Illinois to the list of regulated areas for the gypsy moth (GM). The GM population in each of these counties has reached the threshold to trigger the regulated area.

To prevent the further spread of GM, the attached Federal Order establishes Kane, Kendall, LaSalle, and Will Counties in Illinois as regulated areas. Effective immediately, all interstate movement of GM-regulated articles from Kane, Kendall, LaSalle, and Will Counties must be handled in accordance with the attached Federal Order. Illinois has established a parallel state quarantine. Continue reading

APHIS Updates Gypsy Moth Outdoor Household Article Checklist

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has updated PPQ Form 377: Gypsy Moth Checklist and Record of Your Self-Inspection.  People who live in the gypsy moth quarantine area—generally the northeast quadrant of the contiguous United States—must use PPQ Form 377 to inspect their outdoor household goods for gypsy moth before they move to a non-infested area. The Federal gypsy moth regulations (Title 7 Code of Federal Regulations 301.45-4) require this action to prevent the human-assisted movement of this damaging pest of woody plants. A copy of the form must accompany the household goods during the move. This checklist may be completed by the person moving or by a qualified certified applicator. Once completed and signed, the checklist is an official certificate that will satisfy Federal requirements for interstate moves. Continue reading

A Biological Surprise Attack Slows Gypsy Moth Invasion

In the New York Times

by Andrew Revken

Here’s a tale from the annals of globalizing insect problems and solutions.

In mid-June, I was taken aback twice during a walk in the woods near our home in the Hudson Highlands. First, I realized I was hearing a steady, quiet pitter-patter, like that from a drizzle, but on a sunny day. Glancing down, I saw thousands of tiny green leaf fragments on the forest floor and realized the rain was droppings and table scraps from countless caterpillars munching the newly emerged canopy far above.

Arkansas site addresses invasive pests

From Delta Farm Press:

Invasive pests cost the United States an estimated $130 billion in damage and preventative measures every year, and information is the best defense.

The Arkansas Forest Resources Center has just launched a website, www.ARInvasives.org, dedicated to managing these destructive pests of our forests.

Biological Control Deconstructed, Part 3

If biocontrol has so many advantages, why do some people shudder at the mention of a new introduction of an insect or parasitoid that may save a crop or forest tree from certain destruction? Simple. Any time that any living organism is set free in a foreign habitat, that organism presents its own risks.

Biocontrol Deconstructed, Part 2

The hemlock woolly adelgid has destroyed millions of acres of Eastern hemlocks in the Eastern United States. Other invasives such as the gypsy moth, bean plataspid, and Asian longhorned beetle wreak economic and ecological havoc every year, with few available chemicals to control them. Biological control is often a viable option for pest management when other available controls are not feasible or do not work.

Understanding Population Densities Could Assist in Control of Gypsy Moth

The gypsy moth is one of nature’s most dreaded pests, as it consumes the foliage of over 300 different tree species, and its population keeps growing and spreading. Its population ranges from Ontario to North Carolina, spreading about 21 km per year despite the fact that females cannot fly. In a study published in the online December issue of Ecology Letters, scientists from France and Athens, Georgia, conclude that the pest’s success is driven by its population density.
