Moroccan locust

The genus Calliptamus belongs to the family Acrididae within the order Orthoptera. These insects, commonly known as locusts or grasshoppers, are widely recognized as serious agricultural pests globally. With their robust anatomy and ability to migrate, certain species within this genus can pose a significant threat to food security by devastating vast agricultural landscapes.

This pest is highly polyphagous, meaning it feeds on a wide array of vegetation. Primary targets include cereals such as wheat, barley, and maize, as well as oilseed crops like sunflowers, leguminous plants, and various vegetable species. Due to their voracious appetite, they can cause total crop failure if their population density reaches outbreak levels.

The biological cycle of Calliptamus follows a hemimetabolous development process. The life stage in the soil consists of egg pods (oothecae) laid by females in late summer. These eggs enter a diapause, remaining in the soil throughout the winter. Upon warming in the spring, the nymphs hatch and undergo several molts before reaching the adult stage, at which point they become highly mobile and destructive.

The economic impact is primarily due to the destruction of plant biomass. Nymphs often feed on tender shoots and young leaves, stunting plant development early in the season. Adults consume mature leaves, stems, and reproductive parts, leading to severe defoliation. In severe cases, the crop is completely consumed, leaving behind bare fields and incurring heavy financial losses for farmers.

• Tillage practices, such as deep plowing, to destroy egg pods in the soil.
• Targeted chemical application using registered insecticides.
• Early detection and monitoring of nymphal bands.
• Management of field margins to remove vegetation favored by egg-laying females.
• Integration of biological controls and natural predators to manage populations.
