Influence of regrowth cotton on boll weevil diapause induction and host-free survival
| Problem: | |
| Objective: | |
| Approach: | We will investigate diapause induction and host-free longevity in weevils fed regrowth cotton under naturally-occurring photoperiods and temperatures. |
|
Significant Impact: |
Preliminary studies last year indicated that a small proportion of weevils fed non-fruiting, regrowth cotton for 14 d could attain diapause characteristics, and feeding on such plants could extend host-free longevity. |
