Anacanthocoris

Anacanthocoris is a genus of true bugs belonging to the family Coreidae (leaf-footed bugs) of the order Hemiptera. These insects are specialized phytophages that, despite being less numerous than major agricultural pests, can cause localized but significant damage to various crops and wild plants.

This pest primarily attacks a wide range of legumes and other agricultural plants. The bugs feed on plant sap by piercing young stems, shoots, and developing pods. This feeding behavior disrupts the plant's metabolic processes and hinders proper development, leading to weakened plants and reduced overall vitality.

The life cycle of Anacanthocoris is typical for the Coreidae family, consisting of the egg, nymph, and adult stages. Females lay eggs on the vegetative parts of host plants or in the soil near the host. Nymphs go through several instars while feeding actively, eventually transitioning into the adult stage, which necessitates ongoing monitoring during the growing season.

Damage symptoms include wilting of terminal shoots, deformation of foliage, and underdevelopment of seeds or fruits. The puncture wounds created by their proboscis often serve as entry points for secondary fungal and bacterial infections. In cases of high infestation, crop yields can decrease by 15–20% or more, especially under drought conditions.

Management strategies include a combination of cultural and chemical control measures. Cultural practices focus on removing weed hosts that serve as reservoirs for the bugs before they migrate to crops. When economic thresholds are exceeded, the application of systemic or contact-stomach insecticides, approved for specific crop use, is recommended to mitigate the population and prevent significant yield losses.
