METHOD: Oviposition CONDITIONS: Green House - 16h light at 26C METHOD NARR: Leaves of ber 473331 and 473334 were appressed to tbr cv. Altantic leaflets and presented to PTM adults. Eggs laid on both surfaces of the leaflets werell varieties were subjectd to 4 different treatments designed to remove trichomes and/or their exudates. Again, eggs on leaves were counted as well as those deposited on the cage. Leaf area consumption was determined by traviors were recorded. Trichome density was measured. Sugar ester content of type B trichomes of 473331 was determined. RESULTS NARR: Appressing ber 473331 foliage against a susceptible cultivar dramatically reduced acceptancn. Aggressive removal of the trichomes led to even greater ovipositional acceptance. Neonates on ber 331 required more time to penetrate the leaf surface. Results suggest that the glandular trichomes of ber 331 limit post-penetratio larvae. AUTHOR EXPLANATION: PTM females prefer hirsute surfaces for egg laying, but this tendancy is masked by the presence of hirsute-like trichomes. Trichomes produce a variety of negative behavioral and developmentosition deterrence as the most significant factor.
