|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of the data from the studies are based on a single season’s environmental conditions, it is requested that the data not be published, reproduced, or otherwise taken out of context without the permission of the authors.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.

The cabbage webworm is found throughout the southern United States from Virginia to Florida and west to California. It is rarely a pest in northern climates. In eastern Virginia, it is a common pest on broccoli and cabbage, particularly late in the summer and fall.

|Summary of insecticide efficacy for control of wireworms on potatoes – Virginia (2003-2015)||
Wireworms are the subterranean larval stage of click beetles. These insects can remain in the soil for several years attacking potato seed pieces or tubers or seeds and roots of other crops that are planted in the field. Wireworms can cause serious damage to potato crops by tunneling into tubers, which reduces yield quality and creates entry points for certain plant pathogens that can rot the tuber. Wireworms are attracted to high moisture; and densities are often higher in low-lying portions of fields. Moreover, during extended hot, dry weather, wireworms may seek out the potato tubers for moisture in addition to food; exasperating the damage. It has been well documented that wireworm damage to potato tubers increases the longer tubers are left in the ground.

|Wireworm Pest Management in Potatoes||
Wireworms are the subterranean larval stage of click beetles (Coleoptera: Elateridae). They are pests of many agricultural crops including corn, sorghum, small grains, tobacco, and various vegetables, but are particularly damaging to potatoes, since the marketable portion of that crop is in the soil. Wireworms are found throughout the world, and species vary greatly across regions. In Virginia, three important pest species of agricultural crops are the corn wireworm, Melanotus communis, the tobacco wireworm, Conoderus vespertinus, and a related species, C. lividus (Fig. 1). A field survey of more than 60 fields in eastern Virginia from 2002 to 2004 revealed that 80% of wireworms collected were the corn wireworm, M. communis. This is the primary soil pest attacking potatoes in Virginia.
