Abstract:

Field trials were conducted in 1971-1974 to control the honeydew moth, Cryptoblabes gnidiella Mill, with Bacillus thuringiensis. Dipel, a commercial preparation containing Bacillus 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 mealybug Pseudococcus longispinus Targ.-Tozz., or on its parasites, Hungariella peregrina Compere and Anagyrus fusciventris Girault. © 1975 Springer Science + Business Media B.V.
