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. |

Kudzu Bug, Megacopta cribraria, a pest of soybeans | The kudzu bug (Megacopta cribraria) is an invasive pest from Asia and first appeared in the U.S. in 2009 near Atlanta, Georgia. It has since spread to 18 additional states and the District of Columbia, threatening soybean crops. Recognizable by their mottled dark green and brown coloration, adult kudzu bugs are shield bugs that exude a pungent defensive substance when disturbed. Adults and nymphs feed on plant phloem, causing both direct and indirect damage to plants. Despite initial concerns, populations only occasionally reach damaging levels, but monitoring and management remain crucial. The kudzu bug has two generations per year, with adults emerging from overwintering in early spring. Management includes chemical control with pyrethroids and neonicotinoids, biological control with parasitoid wasps and the fungus Beauveria bassiana, and cultural control by reducing kudzu patches. Here we detail the bug's distribution, life cycle, pest status, and management strategies, highlighting the importance of ongoing vigilance and integrating management 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. |
