Arthropod Pest Management Research on Vegetables in Virginia – 2010

This booklet contains arthropod pest management research conducted on vegetable crops in eastern Virginia in 2010. If not noted otherwise in the individual reports, all research was conducted at the Virginia Tech Eastern Shore Agricultural Research and Extension Center near Painter, VA and at the Hampton Roads Agricultural Research and Extension Center in Virginia Beach, VA. All plots were maintained according to standard commercial practices. Soil type at the ESAREC is a Bojac Sandy Loam. Soil type at the HRAREC is tetotum loam (average pH: 5.7). Most of the research involves field evaluations of federally‐labeled and experimental insecticides. Much of the information presented herein will be published in a similar format in Arthropod Management Tests: 2011, vol. 36 (Entomological Society of America). We hope that this information will be of value to those interested in insect pest management on vegetable crops, and we wish to make the information accessible. All information, however, is for informational purposes only. Because most of the data from the studies are based on a single season’s environmental conditions, it is requested that the data not be published, reproduced, or otherwise taken out of context without the permission of the authors. The authors neither endorse any of the products in these reports nor discriminate against others. Additionally, some of the products evaluated are not commercially available and/or not labeled for use on the crop(s) in which they were used.

Order: Coleoptera

Family: Chrysomelidae

Species: Cerotoma trifurcata (Forster)

Size: Adults are about 1/4 inch (64 mm) long.

Description: Adults range in color from yellow to a dull red with variable numbers of black spots (Fig. 1). Although some have no spots, most will have four black spots down the center of the back with marginal spots or stripes on the edge of the elytra. The distinguishing characteristic is that all have a distinct black triangle behind the prothorax. Eggs are reddish orange ovals about 3/100 inch (0.8 mm) long and have tapered ends. Larvae are white, cylindrical grubs with a black head and anal plate. They have well-developed thoracic legs as well as anal prolegs. The pupae are white and resemble the adult in size and shape.
