dc.description.abstractIn this study, Bacillus thrungiensis aizawai Bonnefoi & de Barjac, 1963 (Florbac), different isolates of Bacillusthuringiensis (Bt) kurstaki Berliner, 1915 (Biobit, Delfin, Rapax, Rebound) and spinosad (Spintor) were assessedfor their efficacy against different instars of Hyphantria cunea (Drury, 1773) (Lepidoptera: Erebidae) underlaboratory and field conditions in 2019 in Duzce Province, Turkey. Spinosad was the most effective bioinsecticide,followed by Bt aizawai and Bt kurstaki isolates against various instars of H. cunea. In the laboratory, at 96 hourpost-treatment, spinosad caused 98% mortality in 2nd and 3rd instars, and 83% mortality in 4th and 5th instars; Btaizawai caused 98% mortality in 2nd and 3rd instars and 43% mortality in 4th and 5th instars; and Bt kurstakiisolates caused 95% mortality in 2nd and 3rd instars and 51% mortality in 4th and 5th instars. The results from thefield study showed similar trends. The older instars were less susceptible to all the tested bioinsecticides than theyounger instars, which may be attributable to the phenomenon known as “maturation immunity”. Bacillusthuringiensis kurstaki has already been recommended for management of this pest. Whereas the data indicatedthat spinosad and Bt aizawai could also be used as bioinsecticides for control H. cunea larvae.en_US
