Abstract:Efforts were made to study the ultrastructure of the nervous systems of dieldrin-resistant and dieldrin-susceptible Blattella germanica (L.). Autoradiographic studies at the electron microscopic level were used to study the movement of the labeled insecticide in the neural matter. It was concluded that the interstrain difference in susceptibilities toward dieldrin is likely caused by the ability of the nervous system of the resistant strain to accumulate Jess amounts of dieldrin. The resistant nervous systems, otherwise, did not show any visually recognizable differences in their gross morphological characteristics from the susceptible systems.
