Abstract: An area of 50 feddans cultivated with soybeans was treated with Bacillus thuringiensis (B.t.) baits against Agrotis ypsilon and 60 feddans were sprayed with B.t. spray against Spodoptera littoralis. When B.t. baits were used, the percentage of kill of A. ypsilon reached 96.1-96.4% compared to 97.4-98% kill on using hostathion baits. When B.t. was sprayed against S. littoralis, a percentage of larval kill 88.3% was obtained. This increased to 97.3% after the second application. On the other hand, the precentage of kill reached 96.8% when lannate was sprayed once. The average yield was 1.54 tons/fed. when B.t. was sprayed twice against S. littoralis and 1.42 tons/fed. when sprayed once. Areas, treated with lannate gave 1.44 tons/fed., while in the untreated area the yield was comparatively low being 0.83 tons/fed.
