Control of the variegated grasshopper Zonocerus variegatus (L.) on cassava

W. W. D. Modder TSpace 1994

Other claims from this paper (10)

Observation Early instars aggregate off farm, while later instars and adults move to crops when food becomes scarce.
Mechanism Aggregated feeding by larger grasshopper instars causes cassava leaves to wilt and lose HCN quickly.
Recommendation Eradication of Chromolaena odorata probably will not control the grasshopper.
Observation Chemical control is described as only short term effective and environmentally damaging.
Intervention effect Chemical sprays against the grasshopper kill parasitoids introduced for cassava mealybug control.
Intervention effect Exposing egg pods at the soil surface produced large grasshopper population reductions.
Intervention effect Fungal spores in kerosene and peanut oil killed 70-95% of field grasshopper populations.
Intervention effect A strain isolated from the grasshopper caused 90% mortality in 7-9 days in the laboratory.
Intervention effect Grasshoppers leaving spore baited traps died within 10 days, up to 30 m away.
