EVALUATION OF BACILLUS thuringiensis (BERLINER) FORMULATIONS AGAINST THE PINK BOLLWORM PECTINOPHORA gossypiella (SAUND.)

Laboratory experiments were carried out to investigate the effect of two bacterial commercial products of B. thuringiensis (Dipel 2x and Protecto) on eggs and the newly hatched larvae of pink bollworm, P.gossypiella. Different concentrations of both commercial products of B. thuringiensis were teste...

الملخص:Laboratory experiments were carried out to investigate the effect of two bacterial commercial products of B. thuringiensis (Dipel 2x and Protecto) on eggs and the newly hatched larvae of pink bollworm, P.gossypiella. Different concentrations of both commercial products of B. thuringiensis were tested. The results showed that the percentage of larval mortality increased by increasing concentration and the period after treatment, calculated LC50s values after 3-7 days of treatment. Treatment of eggs did not affect, significantly, the hatchability. While the percentage mortality of newly hatched larvae produced from the treated eggs was high according to the concentrations used.
