[2] Adelphocoris lineolatus are an Old World Species native to Western Europe, Northern Africa, Asia, and the Middle East.

[4] In the Nearctic realm, these insects range from Southern Ontario and Northeastern United States, to the south of North Carolina, and west of Colorado.

[7] However, alfalfa plant bugs are not successful in salty lakes, deserts, sand dunes, windy weather, or very warm climates.

[6] Adelphocoris lineolatus will easily adapt to cooler environmental conditions, which has allowed them to invade a large amount of territory in Canada.

[9] Alfalfa plant bugs exhibit migratory behaviour, which allows Adelphocoris lineolatus to rapidly increase their population sizes.

[13] Adults and nymphs will consume the reproductive and vegetative organs of their host plants, which are primarily alfalfa and cotton crops.

[14] By feeding on the reproductive and vegetative organs of their host plants, they cause stunted growth and deformation of flowers, fruits, and leaves.

[15] A substantial degree of damage is done to flowering and non-flowering crops because Adelphocoris lineolatus nymphs and adults have similar feeding habits, allowing them to inhabit one particular plant for their whole life cycle.

[15] The chemosensory proteins, AlinCSP1, AlinCSP2, and AlinCSP-3 contain a high binding affinity to the semiochemicals released by flowering alfalfa, cotton, and mung bean plants.

[13] The greatest amount of ecological and economical damage is experienced by these flowering plants because of the semiochemicals they release into the environment, attracting Adelphocoris lineolatus.

[3] A. lineolatus nymphs have become resistant to the following chemical ingredients commonly used in insecticides, mono-methanimidamide, fufenozide, buprofezin, azad irachtin, and triazophos.

[3] Insecticides can be an effective and efficient method of controlling pests, but they do cause a great deal of damage to our environment and we should refrain from using them if possible.

Insect pheromones have successfully been implemented to reduce the amount of damage Adelphocoris lineolatus cause to numerous agricultural crops.

[16] To reduce reproductivity between female and male Adelphocoris lineolatus, an excessive amount of hexyl butyrate (HB) needs to be added to the mixture of E2HB and 4-OHE.
