helicoverpa egg

Catalogue: Broadacre Field Crops DAFF QLD
Loopers can be distinguished from helicoverpa by: their 'looping' action when walking by their body, which tapers to the head they have only two pairs of hind legs, as opposed to four for helicoverpa... Loopers appear susceptible to all insecticides used for helicoverpa control, with the exception of Gemstar and Vivus (NPVs) which only act against helicoverpa... Dipel (Bt) is far more effective against loopers than against helicoverpa but thorough coverage is required for best results...
