ABSTRACT
Bactospeine, a commercial preparation of Bacillus
thuringiensis was tried against Peismopoda
obliquifasciella (Hamps), a serious leaf stitcher of
Amaltas, Cassia fistula. The microbial insecticide gave
84.4, 78.1 and 90.7% mortality of the test larvae with dose of 0.8 x 105, 1.6 x105, and 3.2x105 spores per ml
against a natural mortality of 34.4% larvae in the
check. The efficacy of the product has been proved
against this insect hence it can be used on field scale
to control the peat.
