FIELD, VEGETABLE & BERRY IPM

Spotted Wing Drosophila

The Spotted Wing Drosophila (SWD), Drosophila suzukii, was first discovered in the western US 2008 and is now well-established throughout North America. Female SWD lay eggs in ripe and ripening fruit. This insect is a pest of most berry crops, cherries, grapes and other tree fruits, with a preference for softer-fleshed fruit such as raspberries, blackberries, blueberries. Larvae developing in fruit affects marketability and dramatically reduces storage time. It was detected in ME, NH & VT in 2011. For information on the id, sampling and monitoring and management of SWD, please click HERE. This information was developed for a SWD workshop held on April 10, 2014 in Claremont, NH to help growers around the region better manage this pest.

Western Bean Cutworm

WBC Adult

The western bean cutworm (WBC), Striacosta albicosta, is a late season pest that attacks corn (including field, sweet and popcorn) and both dry and snap beans. Moth larvae feed on developing kernels in husks or beans in pods causing economic damage. Infestations involve multiple larvae per ear causing substantial losses. This moth is native to North America, and prior to 2000 losses occurred only in the western Corn Belt states. It has been on an eastward expansion. It was found in Ontario in 2008, Pennsylvania and New York in 2009, and Vermont in 2011.


WBC Larva	WBC Damage to Corn

This is an emerging pest in the Eastern US. In 2011, scientists at the 抖阴探探 Entomology Research Laboratory collaborated with Penn State and Cornell Univ. on a WBC survey using pheromone traps, which resulted in the first detection in South Burlington, VT. From 2012-2014 we expanded our survey to three VT counties (Franklin, Rutland and Addison) to better understand of WBC distribution and abundance. This will allow farmers to be prepared should there be a need for WBC management in the future. It is expected that this could become a serious pest farmers will have to be aware of in future years.

If you are a VT farmer and you think you have WBC, please contact the Entomology Laboratory at (802) 656-5434 or cfrank@uvm.edu.

Brown Marmorated Stink Bug

The brown marmorated stink bug (BMSB), Halyomorpha halys, is one of the latest exotic invasive pests to reach northern New England, and it is expected to have a major impact on vegetable and fruit production in the future. There have been several sightings in Vermont in 2011 and 2012. It is known to feed on over 300 plants, many of which are important food crops. Damage to crops in New Jersey and Pennsylvania in 2011 was estimated to be in the millions. It also is a serious nuisance pest, when it enters homes in the fall in large numbers. To date, no chemical pesticide or biological control agent has been found to be particularly effective. 抖阴探探 ERL scientists have been testing the effectiveness of the commercial insect-killing fungus Botanigardagainst the adult stage in laboratory trials. Three concentrations of the fungus were tested, and the highest rate killed 67-100% of the adults within 12 days. More research is needed to determine how best to use this microbial product under field conditions.

Several other naturally-occurring insects are often mistaken for the BMSB. Click HERE for a fact sheet on the BMSB as well as their common look alikes.

If you suspect you have BMSB and are unable to identify them, please take the specimens to your Extension specialist to confirm their identity.

Tarnished Plant Bug

The tarnished plant bug (TPB), Lygus lineolarisis, is one of the most serious pests of small fruits, such as strawberries, and vegetables in New England. Feeding by adults and nymphs cause lesions and deformations on fruits resulting in economic losses.

Click HERE for our factsheet on recognizing TPB damage on vegetables, fruits and herbs.

In the early 2000s, the Entomology Research Laboratory examined the effects of several strains of insect-killing fungi for the management of TPB.
The list of publications that contain results from these trials are listed below. Please contact us for more information.
