Abstract: By DR. D. K. EDWARDS Forest Biology Laboratory Federal Building Victoria British Columbia IT is known that weather often can affect insect behaviour and development profoundly. Electrical factors associated with weather may be partly responsible for these biological reactions but very little experimental work has been done to determine if an electrical field can influence insect behaviour and development. Avio and Tarozzi studied Drosophila oviposition in an electrical field (125 V./m.) but found no significant effects. Moro recently Levengood and Shinklo reported higher yields of Drosophila progeny reared in an electrical field. They did not mention however whether there was an observable effect of the field on time of development. Edwards has reported some observations on the behaviour of adult Calliphora and Drosophila in an eloctrical field with Drosophila responding to establishment of the field by temporarily reducing its activity. . . .
