Fig. 5. Mean (± s.e.m.) length (A) and number (B) of secondary oocytes in response to diets (low or high) and timing of gonadotropin treatments (early or late initiation of juvenile hormone analog; JHAi). The number of secondary oocytes was significantly greater on high diet than on low diet in lubber grasshoppers (P=0.001) but was not affected by the timing of JHAi. By contrast, the length of secondary oocytes was greater in grasshoppers subjected to early JHAi than late JHAi (P<0.001) but was not affected by diet. Three groups have no error bars for secondary oocyte length because there was no variance in these data sets.
