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.

BMSB OW

The basics:

  1. Fill out the form
  2. Count the BMSB on the exterior of your home each day
  3. Enter in your count data

Consider participating in the 2014 Great Stink Bug Count!

September 15 – October 15, 2014

You can download particpant forms herehttp://www.stopbmsb.org/2014-count

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!

Beating the Bugs in the Bogs – Sparganothis Fruitworm and Spotted Fireworm

Sparganothis fruitworm and spotted fireworm are important pests of cranberries; therefore, plant resistance against these insects is a major topic of study.

Both insects feed on cranberry uprights and developing fruit during the summer. Dr. Elvira de Lange, a postdoc at the Blueberry and Cranberry Research Center, is especially interested in the resistance factors against these insects that are naturally present in cranberry fruits.

Plastic Pesticide Container Recycling Earns Pesticide Core Credit

The NJ Dept. of Ag, Helena Chemical, and the Cumberland County Solid Waste Complex are offering a series 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. Spread the word and recruit participants for this free service – we are hoping to exceed last year’s collections.

The NJ Dept. of Ag will be on-site to inspect the containers and issue one Core Credit to license holders who follow the processing guidelines. To receive Credit, participants must bring their Pesticide License and prepare the containers. Core credits will not be issued to participants who do not prepare containers. Dates and locations are listed below.

Cranberry Toad Bug: A New Cranberry Pest

Last year we observed damage in cranberry bogs by the cranberry toad bug, Phylloscelis atra, in New Jersey. Although we had seen toad bugs in cranberry bogs in the past we had never seen them causing damage to the vines and fruit. Toad bugs are hemipteran insects, similar to blunt-nosed leafhoppers, but belong to the Family Fulgoridae (planthoppers) as opposed to leafhoppers, which belong to the family Cicadellidae.

Life Cycle

Toad bugs feed only on cranberries. This insect has a single generation per year. It overwinters as eggs. The nymphs appear by the end of June through August, and the adults from August through October. Eggs are laid from September through October.

Root-feeding Pests of Cranberries

If your beds have damage caused by root-feeding insects, you should consider treatment with Imidacloprid (e.g. Admire Pro, Alias 4F, Alias 2F) immediately after bees are removed.  Occurrence of root-feeding insects will manifest by the presence of dead patches.  Pull dead vines and search through the root zone and soil for grubs and worms.  Admire Pro (imidacloprid) is labeled for the control of cranberry rootworm, white grubs (Phyllophaga spp.), and other scarabs in cranberries.
