I examined the adult potential fecundity of the bamboo gall maker, Aiolomorphus rhopaloides Walker (Hymenoptera : Eurytomidae), and its inquiline, Diomorus aiolomorphi Kamijo (Hymenoptera : Torymidae) by dissection just after emergence, and at death after rearing. Emerging females of A. rhopaloides had ca. 80 mature eggs in their ovaries. The number of eggs at emergence and after death at rearing was not significantly different. However, emerging females of D. aiolomorphi had no eggs in their ovaries but had ca 20 eggs at death after rearing. These results suggest that A. rhopaloides is pro-ovigenic and D. aiolomorphi is synovigenic. Female body sizes of both species were positively correlated with the size of galls from which each emerged. Number of eggs in each species was also correlated with female body size, suggesting that gall size might be a good predictor of potential fecundity.
