Evaluation of nine strains of Bacillus thuringiensis Berliner against the giant looper, Boarmia (Ascotis) selenaria Schiffermüller (Lepidoptera, Geometridae)

Abstract: 

Nine isolates of Bacillus thuringiensis Berliner belonging to var. kenyae, var. aizawai and var. entomocidus, were bioassayed against 1st instar larvae of Boarmia (Ascotis) selenaria Schiffermüller and compared with B. thuringiensis var. kurstaki, HD-1-S-1980. None were found to have a higher potency than HD-1-S-1980, which is used for commercial control of young larvae of this pest in avocado plantations in Israel. © 1986 Verlag Paul Parey.
