Description
Origin and Distribution
- Grasshoppers are distributed worldwide and occasionally reach serious pest outbreak status causing major crop loss. Occasionally, large flights of grasshoppers are detected on radar.
Habitat & Hosts
- Almost any type of plant including corn, alfalfa, Bermudagrass, cotton, millet, peanut, rice, ryegrass, sorghum, Sudangrass, soybean, sugarcane, vegetables, wheat, flowers and landscape plants.
Life Cycle
- Grasshoppers deposit their eggs 1⁄2 to 2 inches below the soil surface in pod-like structures. Each egg pod consists of 20 to 120 elongated eggs cemented together. The whole mass is somewhat egg-shaped. Egg pods are very resistant to moisture and cold and easily survive the winter if the soil is not disturbed. Eggs are deposited in fallow fields, ditches, fencerows, shelter …

- Nosema locustae is a protozoan that can be purchased commercially to treat large areas. Its spores have been incorporated with bran to make insecticide baits such as Semaspore®, Nolo Bait® or Grasshopper Attack®. These baits kill some nymphs but almost no adults, though infected adults lay fewer eggs. Baits act too slowly and kill too few grasshoppers to be useful fo…
