Box 110620, Gainesville, FL 32611-0620 Influence of Leaf Pubescence on Ovipositional Preference of Bemisia argentifolii (Homoptera: Aleyrodidae) on Soybean [Elektronische Daten] [Heather J. Mcauslane] The influence of pubescence on oviposition site selection by Bemisia argentifolii Bellows & Perring [also known as the B strain of sweetpotato whitefly, Bemisia tabaci (Gennadius)] was studied in greenhouse and laboratory bioassays using soybean, Glycine max L., isolines varying for foliar pubescence. In choice tests, whiteflies laid significantly more eggs on the hirsute and pubescent isolines than on the glabrous isoline. In no-choice tests, the within-plant distribution of eggs laid on the 3 isolines differed and was related to trichome density. On glabrous soybean, more eggs were laid on the 2 oldest and 2 youngest leaves. On the 2 hairy isolines, more eggs were laid on the 3 oldest leaves and fewer eggs were laid on the younger leaves, which had the highest densities of trichomes. When whiteflies were confined in petri dish-clip cages attached to plants with a choice between 2 leaflets, either from 2 different isolines or within a single isoline, no preference for pubescent over glabrous soybean was seen nor did removal of hairs by shaving affect ovipositional preference. However, significantly more eggs were laid on hirsute soybean than on glabrous soybean in between isoline choice tests. In addition, shaved hirsute leaflets were less preferred for oviposition than hirsute leaflets in within-isoline choice tests. It is likely that the partial resistance of glabrous soybean observed in the field is caused, in part, by reduced ovipositional preference related to lack of foliar pubescence. However, the effect of trichomes on ovipositional preference is less pronounced when whiteflies are closely confined with host plants. © 1996 Entomological Society of America Population Ecology nationallicence Bemisia argentifolii nationallicence whitefly nationallicence soybean nationallicence plant resistance nationallicence trichomes nationallicence ovipositional preference nationallicence Environmental Entomology Oxford University Press 25/4(1996-08-01), 834-841 0046-225X 25:4<834 1996 25 ee https://doi.org/10.1093/ee/25.4.834 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/ee/25.4.834 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Mcauslane Heather J.
