Abstract
Commercially prepared spore powders containing 3 x 109, 25 x 109 and 47 x 109 spores of Bacillus thuringiensis Berliner per gram were fed in the ration of caged layers. There was considerable variation in fly (Musca domestica L.) control obtained in the droppings when the different formulations were fed at the same spore levels. A reduction in feed consumption, body weight and egg production of caged layers was noted when the most effective material (Rohm and Haas) was fed in the ration at and above 53 x 106 spores per gram of feed.This publication has 1 reference indexed in Scilit:
