The experiments were carried out in 1997-1998 in greenhouses with cucumber, tomato and pepper cultivars to establish the preference of the pest to some of them, judging on the degree of the damages caused. Liriomyza huidobrensis Blanchard showed preference to cucumber, followed by tomato. Pepper was the least preferred. From 13 tomato cultivars the most heavily attacked were Baldo and Ruen, the least preferred - Kom, Rila and Balkan. The degree of damage varied from 23,05 to 31,46% mined leaves per plant. From 6 cucumber cultivars the least preferred was cv. Aricya, and the most attractive for the leafmining flies were the cultivars Piralis, Kalunga, Sandra and Fitness. The degree of damage is higher, compared to that of tomatoes, and varies from 67,05 to 85,03% mined leaves per plant. The pepper cultivar Hebar is less preferred, compared to cv. Albena. The pepper was the most attractive for the females for making fedding punctures with 0,76 per cm2 leaf surface, while for cucumber the value was 0,22 (cv. Sandra) to 0,55 (cv. Guergana), and for tomato - 0,08 punctures/cm2.
