Fig. 3. Mean (± s.e.m.) times from gonadotropin treatments (initiation of juvenile hormone analog; JHAi) to oviposition in response to diets (low or high) and timing of JHAi. Regardless of whether the feeding threshold for vitellogenesis has been attained, early JHAi increases the time remaining until oviposition in lubber grasshoppers (P=0.013).
