In addition to the beetles' direct attack, adults are also known vectors of the bean pod mottle, cowpea mosaic, and southern bean mosaic viruses. About 4 days later, brown-headed grubs emerge and infest the seeds of beans and peas. Another option is to apply a broadcast insecticide soil treatment that is incorporated into the soil prior to planting.

Remove them with their roots and dispose of them safely, the same way as any crop plants. Combination fungicide-insecticide seed treatments or soil-applied insecticides can be used to prevent seedcorn maggot damage. The methods used are less hazardous to human health, less toxic to non-target organisms, easier and more cost-effective, plus are more likely to be effective in the long-term. Figure 4A. Pupa The pupa is brownish and about 8.5 mm long. They're easy to grow, help fix nitrogen, and can be enjoyed in multiple forms - in their pods, shelled, or dried. Soybean thrips. Predacious ground beetles also eat seed corn maggot eggs, larvae, and pupae. Figure G. Mexican bean beetle with larva, pupa, and eggs. Conservation tillage seems to result in lower maggot populations because the organic matter stays on the surface of the soil rather than being incorporated into the soil. Adult The pea aphid adult is long-legged, light to deep green with reddish eyes. Early season drought may cause an ordinarily harmless thrips population to become a problem.
