| Abstract: | Field trials were conducted in 1971–1974 to control the honeydew moth,Cryptoblabes gnidiella Mill, withBacillus thuringiensis. Dipel, a commercial preparation containingBacillus thuringiensis var.kurstaki (HD-1 strain), was highly effective (at concentrations ranging from 0.25% to 1.5%) in killing caterpillars of all developmental stages. In both the field trials and additional laboratory trials, it had no adverse effect on the mealybugPseudococcus longispinus Targ.-Tozz., or on its parasites,Hungariella peregrina Compere andAnagyrus fusciventris Girault. |
