Bacterial symbionts can promote insecticide resistance in their hosts by isolating and degrading insecticidal compounds or altering the expression of host genes. Although Wolbachia, a common endosymbiont arthropods, typically does not influence resistance, there are cases increased decreased susceptibility. Due to restrictions applying conventional insecticides stored product setting, studies o...

The butanol fraction of the leaves of Castanospermum australe Cunn. & Fraser., was tested on adult Callosobruchus analis (pulse beetle) for its insecticidal activity by impregnation method at concentration of 3, 9, 48, 240 and 354 μg / cm. The result showed that the extract is toxic to Callosobruchus analis and the LD50 was found to be 38 g/cm . KeywordsCallosobruchus analis, Castanospermum au...
