Four species of aphids attack small grains in Virginia - greenbug, corn leaf aphid, bird cherry-oat aphid, and English grain aphid.

Numerous kinds of insects can be found in soybeans. Most are beneficial or harmless, but some can cause yield loss and even crop failure if not controlled.

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.
