Abstract:A field experiment was conducted for trapping efficiency of three kinds of sex pheromone lure for Spodoptera litura Fab. in Lujiang County, Anhui Province from July to September in 2006 Water trays with rubber plug were baited with different sex pheromone blends 0, 1 and 2. Each lure treatment was designedwith four replicates. The results during a period of 64 days showed that the mean numbers of the target moths trapped each tray with lure 2, 1 and 0 were 169.5,65.5 and 1.5, respectively. The differences among three lure treatments were significantly (P<0.05). Meanwhile, the mean number of trapped moth by lure 2 was significantly higher than that of a commonused 20 W blacklight tube (P<0.01). Moreover, the date of capture peak with lure 2 was more consistent with the date of egg peak in cotton fields than the black-light tube.
