- Observation Female S. frugiperda did not appear to use plant volatiles to orient to host plants.
- Intervention effect Females laid more eggs on controls than areas treated with cotton leaf extract.
- Intervention effect Females laid more eggs on controls than areas treated with tomato leaf extract.
- Observation The extract effect was independent of extraction time and solvent.
- Intervention effect Corn hexane extract inhibited moth oviposition at 1 and 0.2 g/ml.
- Intervention effect Corn hexane extract did not inhibit oviposition at 0.005 and 0.001 g/ml.
- Intervention effect Methanolic leaf extract decreased oviposition at 1, 0.2 and 0.005 g/ml.
- Intervention effect Methanolic leaf extract did not decrease oviposition at 0.001 g/ml.
- Intervention effect Female moths deposited more eggs on grooved or pitted than smooth surfaces.
- Observation Grooved surfaces supported oviposition regardless of whether leaf extracts were present.
