Abstract
In Orthoptera, the endocrine control of reproduction has been investigated mainly in Acrididae. Gryllidae are also good models for the study of hormonal control of reproduction and reproductive behavior. In this review, special attention will be focused on the house cricket, Acheta domesticus. In the house cricket, vitellogenesis is controlled according to the classical model described for most insect orders. However, whereas allatectomy completely abolished oocyte growth in A. domesticus, it did not totally suppress ovarian development and egg-laying in Teleogryllus commodus, Gryllus bimaculatus, and G. campestris. In the Gryllidae studied thus far, juvenile hormone (JH) is not needed for mating behavior. In adult A. domesticus, the expression of oviposition movement, although independent of the presence of the ovaries, is strictly controlled by JH III. Recent findings suggest hormonal actions on the central nervous system of the house cricket, and provide a stimulating basis for further research on the respective involvement of hormones and nervous system in the control of reproductive behavior in adult crickets.
