FAQ

Frequently Asked Questions

No, they are different species. The migratory locust (Locusta migratoria) and the desert locust (Schistocerca gregaria) are both swarming locusts but have different geographical ranges and some biological differences.

Typically, no. They are powerful fliers but generally migrate over landmasses. However, swarms can cross significant water bodies like the Red Sea with favourable winds.

They are polyphagous, meaning they eat many kinds of plants, but they primarily target grasses and cereal crops like maize, wheat, and rice, consuming their own body weight daily.

Control involves monitoring, early warning systems, and targeted application of insecticides via ground or aerial spraying to kill nymph bands before they form flying swarms. Biological control methods are also researched.
