The black bean aphid is a small, soft-bodied (meaning that the exocuticle part of the exoskeleton is greatly reduced) [5] insect that has specialised piercing and sucking mouthparts which are used to suck the juice from plants. This aphid is usually seen in large numbers and is a tiny, plump insect about two millimetres long with a small head ...
Megacopta cribraria, also called the bean plataspid, kudzu bug, globular stink bug and lablab bug, is a shield bug native to India and China, where it is an agricultural pest of lablab beans and other legumes. [2] The bug, while harmless to houseplants and people, often enters houses.
Bean leaf beetle abundance increased with the increase of soybean production in the 20th century, but their spread northward was prevented by the inhospitality of northern climates. [ 3 ] The availability of soybean is the primary constraint for the beetles, so the beetles can’t live in an area that doesn’t have soybeans. [ 3 ]
Beans, peas, and bean pod with holes drilled by Bruchus rufimanus. Bruchus rufimanus, commonly known as the broadbean weevil, broadbean beetle, or broadbean seed beetle is a leaf beetle which inhabits crops and fields, as well as some homes. It is a pest of faba beans (Vicia faba L.).
The bean weevils or seed beetles are a subfamily (Bruchinae) of beetles, now placed in the family Chrysomelidae, though they have historically been treated as a separate family. They are granivores, and typically infest various kinds of seeds or beans, living most of their lives inside a single seed. The subfamily includes about 1,650 species ...
Some are considered pests because they invade stores of legume foods, such as beans and lentils. They lay eggs on the seeds and the larvae consume them as they develop. They emerge from the seeds as adults. [2] C. maculatus in particular is well adapted to living in dry beans and seeds because it does not require food or water to reproduce. It ...
Crops which support aphid populations include wheat, sorghum, sweet corn, alfalfa, soybeans, peas, beans, cotton, potatoes, brassicaceous crops, tomatoes, asparagus and apples. [3] Besides aphids, they include in their diet adelgids , [ 2 ] mites , insect eggs (an example is fall webworm eggs) [ 4 ] and small larvae.
