Effect of Tephrosia purpurea Extract on Fecundity Of Corcyra cephalonica (st.)
نویسنده
چکیده
The naturally occurring allilochemics play a promising role in insect control by deterring insect feeding by their effects as insect growth regulators, as antihormones or as insecticides. Effect of Tephrosia purpurea extracts on reproductive ability i.e. fecundity was reduced at more than 40.08 %. There is reduction in hatching percentage also. It may be due to reduced juvenile hormone titre which resulted inhibition of egg development. It changes the hormone pool hence disturbs the egg maturation process. It indicates that Tephrosia purpurea extract would make a substantial contribution to the recent efforts towards a safer and more effective pest control programme.
