Abstract:
The effectiveness of a commercial preparation of Bacillus thuringiensis Berliner (Dipel) against eggs and larvae of Boarmia (Ascotis) selenaria Schiff. of different age was examined in laboratory and in field tests. The mortality rate of B. selenaria was proportional to the concentration of B. thuringiensis and inversely related to the age of the treated larvae. In neonate larvae, 100% mortality was obtained even with a low concentration (0.5%). Egg hatch was not affected, but the survival rate of larvae hatched from treated eggs was very low (2.2%). No phytotoxicity of the commercial microbial preparation was observed on fruit or leaves of avocado. High doses of B. thuringiensis persisted on avocados, probably because of specific conditions:i.e., absence of rainfall, moderate temperatures and limited penetration of sunlight. Tests carried out in large commercial orchards, using motor-guns and helicopters, yielded good results. © 1979 Springer Science + Business Media B.V.
