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

  • M. Wysoki
  • Liisa Jarvinen


Nine isolates ofBacillus thuringiensis Berliner belonging to var.kenyae, var.aizawai and var.entomocidus, were bioassayed against 1st instar larvae ofBoarmia (Ascotis) selenaria Schiffermüller and compared withB. 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.

Es wurden 9 Isolate vonB. thuringiensis Berl., die zu den Subspezieskenyae, aizawai undentomocidus gehörten, gegen die Raupen vonBoarmia (Ascotis) selenaria getestet und mit der Wirkung vonB. thur. var.Kurstaki HD-1-S-1980 verglichen. Keines von ihnen zeigte eine bessere Wirkung als HD-1-S-1980, das in Israel zur kommerziellen Bekämpfung der Jungraupen dieses Schädlings in Avocado-Plantagen Verwendung findet.
