Abstract:Bacillus thuringiensis Berliner var. kurstaki was lethal to adults of Heliothis virescens (F.) when fed to moths in a sucrose solution. Results suggest that spores alone are capable of producing a lethal response, although mortality is enhanced when crystals are present. Sprays of B. thuringiensis (1.12 kg/ha) combined with sugar (5.6 kg/ha) were superior to B. thuringiensis applied alone or in combination with molasses in reducing longevity and fecundity of adults confined on treated colton terminals or released onto treated plants in field cages. Reduced fecundity observed in B. thuringiensis treatments was apparrently a function of shortened adult longevity.
