Adelphocoris lineolatus, is commonly known as the Lucerne bug or the alfalfa plant bug, and belongs to the family Miridae. It is an agricultural pest causing vast amounts of damage to numerous crops, but primarily to alfalfa crops around the globe.
Adelphocoris lineolatus are an Old World Species native to Western Europe, Northern Africa, Asia, and the Middle East. In 1917, this species had been introduced into Canada and the United States. In the Nearctic ecozone, these insects range from Southern Ontario and Northeastern United States, to the south of North Carolina, and west of Colorado.
Alfalfa plant bugs require a certain set of optimal conditions in order to thrive and become a pest in any country. A. lineolatus are primarily located in humid environments with cold temperatures. Commonly one can find these plant bugs in either fields or grasslands, in both dry and damp areas. However, alfalfa plant bugs are not successful in salty lakes, deserts, sand dunes, windy weather, or very warm climates.Adelphocoris lineolatus will easily adapt to cooler environmental conditions, which has allowed them to invade a large amount of territory in Canada.
Adelphocoris lineolatus have an elongated body shape and are large in body size. Alfalfa plant bug males body size ranges from, 8.3-9.5 millimetres. Whereas, the females are a little bit smaller than the males having a body size between, 7.6 and 8.3 millimetres. Their antennae are usually the same length as their body size, sometimes a bit shorter. A longitudinal brown triangle is located on the middle of their corium. The scutellum of A. lineolatus have two longitudinal brown lines on the surface. The pronotum of the alfalfa plant bug will have two black spots on it. It commonly observed that their femora are spotted with brown specks. Also, the ocular index between male and female Adelphocoris lineolatus differs. Males have an ocular index of 0.83 millimetres. Whereas, females have an ocular index of 1.5 millimetres. Certain regions of their bodies are covered with black hairs, and others with pale coloured hairs. The body colour can range from a light green to a pale brown. Nymphs are green and have red eyes. In A. lineolatus nymphs there is an absence of wings, but in adult species wings are seen.
