transmission possibility of the fungus beauveria bassiana kcf102 by mating behavior between sunn pest, eurygaster integriceps (hem.: scutelleridae) adults

horizontal transmission of an isolate of the etomopathogenic fungus, beauveria bassiana kcf102, was examined by allowing inoculated eurygaster integriceps put. adults to mate with non-inoculated ones. in case of susceptibility to b. bassiana, there was no significant difference between the males and females. however, there was significant difference among treatments for mortality of non-inoculated adults. it meant horizontal transmission could be happened between the inoculated and non-inoculated adults. recording no significant difference among the treatments of the inoculated males + non-inoculated males and treatment with inoculated females + non-inoculated males revealed that this kind of horizontal transmission was not merely due to the mating behavior, given that the same transmission could be existed between inoculated and non-inoculated males or between those of female adults. there was significant difference for mortality percentage of adults among the five body-part treatments, ranging from 16.6 to 48.9, with the highest mortality for total body treatment and the lowest one for the pronotum.
