Degree-day benchmarks indicate discrete biological events in the development of insect pests. For the Sparganothis fruitworm, recent studies conducted by Dr. Shawn Steffan (USDA-ARS/University of Wisconsin-Madison), Annie Deutsch (University of Wisconsin-Madison), and Cesar Rodriguez-Saona (Rutgers University) have isolated the key development events and linked them to degree-day (DD) accumulations. These degree-day accumulations can improve treatment timings for cranberry IPM programs in spring and summer.

Plastic Pesticide Container Recycling Dates
The NJ Dept. of Ag, Helena Chemical, Allied Recycling, and the Cumberland County Solid Waste Complex are offering dates for free plastic pesticide container recycling disposal. These are offered to agricultural, professional and commercial applicators holding a NJDEP Pesticide Applicators License. State, county and municipal government agencies may also participate.
Dates and locations are listed below.

Bug Damaging Cranberries Identified: Plagiognathus repetitus
This year we observed damage to cranberries likely caused by an unknown “mirid” bug (Hemiptera: Miridae). These insects are known as true bugs and have piercing-sucking mouthparts to suck juices out the plants. The species has now been identified by Dr. Thomas Henry, from USDA-ARS-Systematic Entomology Laboratory in Beltsville, MD, as Plagiognathus repetitus (Hemiptera: Miridae).
The insect seems to damage young leaf and flower buds. We observed deformed leaves and flowers in June. This damage appears to cause serious reduction in yield. The damage was likely caused by the nymphs in April-May, as adults were seen in June-July.[Read more…]
Volunteers Needed for Brown Marmorated Stink Bug Count
Scientists at the USDA are conducting a second year of the “Great Stink Bug Count” and are looking for volunteers from NJ! They are trying to identify characteristics of houses that brown marmorated stink bugs look for when finding overwintering sites. Last year’s count had over 200 volunteers with 44 individuals who counted every day.
The basics:
- Fill out the form
- Count the BMSB on the exterior of your home each day
- Enter in your count data
Consider participating in the 2014 Great Stink Bug Count!
September 15 – October 15, 2014
You can download particpant forms here: http://www.stopbmsb.org/2014-
Results from 2013 are the first to document factors that may be important in where bugs chose to overwinter. Last year’s results suggest that landscape factors, specifically agriculture and woodland habitats, may have the greatest influence on the number of BMSB overwintering on a house.
This data will go a long way to helping us figure out important steps to managing BMSB. They are looking for citizen scientists to help out! Please fill out the attached form and send it in if you are interested!
