Corn Earworm on Vegetables
Corn earworm is a pest of multiple agricultural crops grown in Virginia, including vegetables. These pests have a wide host range and can cause extensive damage, but monitoring and a variety of control methods help suppress populations and prevent losses.

Pepper Maggot, Zonosemata electa, in Sweet (Bell) Pepper
The pepper maggot, Zonosemata electa, is a significant pest of bell pepper in eastern North America, having transitioned from its native wild host, the horse nettle, to domesticated solanaceous plants like bell pepper and eggplant. Infestation levels can be alarming, with near-total crop loss possible from a single maggot per fruit. Control methods primarily involve insecticide applications, posing challenges for organic producers. The pest has a single annual generation, overwintering as a pupa in soil. Monitoring adult populations using yellow sticky traps and oviposition scars is essential for effective management. Cultural practices such as field sanitation, crop rotation, and the eradication of alternate hosts are crucial in mitigating damage. Additionally, trap cropping with hot pepper varieties and perimeter sprays have shown success in reducing damage to bell peppers. Various insecticides are available for pre-emptive control, emphasizing the importance of monitoring to optimize application timing.

Sugarcane Beetle, Euetheola humilis
Sugarcane beetle is a sporadic but serious pest of several crops in Virginia. Although an occasional pest, outbreaks can lead to substantial losses in crops and property damage. It can cause significant damage to corn, sugarcane, rice, sweetpotato, and turfgrass, and has also been reported on strawberry, cotton, rose, and wild grasses. Populations in southern states may flare to levels that become a nuisance as it gathers at light sources. Its life cycle spans one generation per year, with adults becoming active in late spring. These beetles primarily feed on plant roots and management involves cultural practices and chemical control, focusing on targeting adult beetles to reduce crop damage. Further research is needed to develop effective pest management strategies that rely less on chemical control tactics.

Soldier Beetles (Leatherwings)
This publication reviews the biology of cantharid beetles. Cantharids, known as soldier beetles or leatherwings, are commonly-encountered beetles throughout Virginia. Two species in the genus Chauliognathus are the most frequently observed; the margined leatherwing (Chauliognathus marginatus) is found during the spring and early summer, while the Pennsylvania leatherwing or goldenrod soldier beetle (Chauliognathus pensylvanicus) is active during the late summer and early fall. Both species visit a variety of wild and cultivated flowers, and they can be considered beneficial insects.
