Examination of factors affecting Mexican corn rootworm reproductive biology
| Problem: |
Previous research indicated a sharp increase in the occurrence of females with well-developed ovaries in relation to corn plant phenology. The mechanisms influencing initiation of ovarian development for female Mexican corn rootworm adults has not been documented. |
| Objective: | This study will examine Mexican corn rootworm reproductive development in relation to feeding source. |
| Approach: | Beetles of known age will be provided various diets to examine the influence of diet on ovarian development. Females will be dissected at pre-determined intervals to evaluate ovarian development, and some females will be allowed to oviposit to obtain an estimate of fecundity. As a sub-objective, we may examine the influence of mating status and mating frequency on fecundity. |
| Significant Impact: | First year of this study. |
