摘要:
First-instarTrichoplusia nilarvae feeding on cabbage deterred oviposition by adult moths in laboratory assays.The effect remained for at least 3 days after removal of larvae from plants.When cabbage plants were treated with a dispersion of larval frass in water, oviposition was also deterred. The results suggest that larval frass can serve as a signal of occupancy to gravid females searching for oviposition sites.
