dc.description.abstract The purpose of the study was to determine the preference of Bemicia tabaci to tomato plants with different morphological characteristics as a passive resistance mechanism of the plant against tomato yellow leaf curl virus (TYLCV) transmitted by the insect. The study was conducted in the Vegetable Crops Research Institute, Lembang, West Java, Indonesia (1,200 m above sea level) from June to December 2006. About 400 individuals of B. tabaci were released in the center point of a 1-m diameter circle, surrounded by four weeks old seedlings of 31 tomato assessions. The assessions were ranked based upon the insect preference (the number of insects found per plant), namely: (1) 0 individual per plant; (2) 1- 5 individuals/plant; (3) 6 - 10 individuals; (4) more than 10 individuals/plant. Morphological characteristics of each assession were also observed, i.e: the leaf number/plant, leaf area, hair density, and stomata number. The morphological characteristics were individually subjected to linear regression analysis against the level of B. tabaci preference to the assessions. Our results showed a positive correlation between the number of B. tabaci present on a plant and the number of leaves per plant (R2 = 0,15) and leaf area (R2 = 0,11). However, a negative correlation was detected between the number of insects per plant and hair density or the number of stomata per leaf. The insect showed higher preference to assessions with thicker leaves and epidermal cells. Out of 31 tomato assessions tested, 15 were categorized slightly unattractive to the vector (1 - 5 insects per plant), namely: assessions 2208, 3078, 3075, 3077, 3083, 4444, 4584, 4673, 1176, 1217, 1646, CL 6064, CLN 2026-3, CLN 294. These assessions are potentially used in a breeding program for developing new resistant varieties against the vector. en_US
