Clear-winged grasshopper

The clear-winged grasshopper, scientifically known as Camnula pellucida, belongs to the order Orthoptera and the family Acrididae. It is a highly significant agricultural pest, particularly in North America, known for its ability to congregate and cause widespread damage to diverse landscapes.

This species is a generalist feeder that shows a marked preference for cereal crops and grasses. Major host plants include wheat, barley, oats, rye, corn, and various pasture grasses, making it a critical threat to both arable farming and livestock feed production.

Its life cycle consists of the egg stage, which overwinters in the soil, followed by five nymphal instars, and finally the adult stage. The hatching period is heavily influenced by soil temperature and moisture levels, with warm, dry springs creating ideal conditions for population outbreaks.

Damage is characterized by the consumption of foliage, stems, and flowering parts of plants. During massive infestations, these grasshoppers can strip entire fields of vegetation, leading to substantial economic loss and reduced grain quality, often forcing farmers to seek immediate control measures.

Management strategies focus on early detection through field scouting and monitoring egg-laying sites. Cultural control includes tillage to disrupt egg beds, while chemical control involves the application of insecticides targeting nymphs before they reach the adult stage, which is significantly more difficult to manage.

• Scouting fields for nymph clusters.
• Tillage of egg-laying habitats.
• Application of selective insecticides.
• Monitoring weather patterns to predict outbreak years.
