Of Central American origin, the lima bean is of commercial importance in few countries outside the Americas. Dry lima beans, which are canned or packaged for domestic or export markets, are grown in California. Usually, infested plants are weakened and have lower yields. Maggots find this mixture uninhabitable, so it can also prevent future infestations. University of Alaska Fairbanks, Cooperative Extension Service. When the seed coat of the lima beans is not adequately softened, the rehydration of the inside of the bean causes the bean to split open when the exterior does not expand. Egg The lemon-shaped egg is orange and about 0.85 mm long. The female's front wings are nearly black.

Intercropping Beans are excellent for intercropping with other food crops, such as maize . Lima beans. Since beetles are susceptible to any broadcast soil insecticides, they should be used sparingly. A dark sooty mold often grows on the honeydew-coated surfaces of aphid-infested plants. One of the most reliable control methods now in general use is to plant seeds that have been treated with an appropriate insecticide. Whiteflies. The larvae or maggots develop over a large temperature range: 52 F-92 F (11-33 C). Larva The larva is basically whitish with both ends colored dark brown.

Damage Congregating on lower leaf surfaces and on terminal buds, aphids extract plant sap. Damage The Mexican bean beetle is the most injurious pest of beans (snap, lima, pole, kidney, pinto, navy, bush). The undersurfaces of leaves usually are covered with silken webs over which the mites crawl. These beans get a bad rap, but there's actually so much to love when it comes to lima beans. On lima bean, bean aphids attack terminal leaves, flower heads, and stems of pods. Figure 4C. The prepupa is about 1.2 mm long and shrinks to about 1.0 mm as it becomes a pupa. Chemical control consists of applying foliar insecticides to the undersides of leaves or using a granular insecticide in furrow at planting. In addition, wireworms (the larvae of the adult click beetle) also invade seeds of various vegetable crops. A few of its vegetable hosts include asparagus, broad and lima beans, carrot, celery, corn, cowpea, cucumber, eggplant, lettuce, onion, pea, pepper, potato, spinach, tomato, and turnip. This practice reduces the overwintering population. Although common species such as onion maggot and cabbage maggot are named after their main host plant, they also feed on numerous other vegetables. In North Carolina, these beetles damage leaves and stems from late May through September. Life History In North Carolina, thrips overwinter as hibernating adults in sheltered areas, as larvae on plants or as pupae in the soil. They are typically small and possess somewhat of an oval shape, although particular appearance may differ by the type of bean. Department of Entomology, University of Minnesota.

European corn borers are grayish pink with a dark head and rows of small brown doughnut-shaped spots on the back. Infestations tend to occur more commonly when the springtime weather is cool and wet. Shallow planting of seeds in well-prepared seedbeds also enhances quick germination, making the seeds less susceptible to seed corn maggot infestation. B.
