Laboratory experiment reveals that physical texture and chemical cues regulate egg-laying in diamondback moths, indicating that both positive and inhibitory signals dictate host plant choice.

Key Points

To determine how physical leaf texture and chemical constituents regulate oviposition site selection in adult female diamondback moths.
Assayed female oviposition preferences across natural plant tissues and artificial polyvinyl plastic substrates with either smooth surfaces or dimpled concavities.
Evaluated the stimulatory effects of mustard leaf juice and allyl isothiocyanate alongside the inhibitory effects of sulfur-deficient diets, coumarin-rich Melilotus, and tomato leaf extracts.
Significantly higher numbers of eggs were deposited on dimpled polyvinyl plastic surfaces than on smooth surfaces, and adding allyl isothiocyanate or mustard leaf juice increased egg deposition across both substrate types.
Sulfur-deficient nutrition depleted isothiocyanates and lowered host plant attractiveness, while the inhibitory effect of coumarin in Melilotus was overcome by applying allyl isothiocyanate.
Unidentified inhibitory constituents in tomato leaves completely suppressed egg laying even when supplemented with allyl isothiocyanate.
