Abstract
Progress in the use of B. thuringiensis in the control of bunch moth (Pyralidae) nettle caterpillars (Limacodidae) and bagworms (Psychidae) is reviewed. Bacillus thuringiensis Berliner (Thuricide) was more effective than diflubenzuron cyfluthrin and endosulfan in the control of the bunch moth. Few field trials on the use of B. thuringiensis against nettle caterpillars have been reported to date. In all reported instances except one it was found to be effective. The performance of B. thuringiensis against bagworms is similar to that against nettle caterpillars: there has been no field success. Laboratory investigations with the bagworm Metisa plana revealed that of the eight products tested (Bactospeine Thuricide BCBT II Florbac Foray Dipel Biobit FC and CGA-BT-237218) only Florbac showed some potential in control causing 80 mortality of the fourth instars after seven days. The mortality values with other products as well as with Florbac against second instars were generally less than 60 per cent. Investigations on concentration-mortality responses revealed that a high concentration would be required to effect a 75 kill the level regarded as acceptable for biocontrol agents. Subsequently various suggestions are made on how to overcome the lack of potency of B. thuringiensis against the larvae of M. plana
