Tomato leaf miner[Tuta absoluta(Meyrick)]is an important invasive pest,which brings serious threat to the tomato industry.To demonstrate the trap effects of different setting method of blue sticky cards on the captured number of T.absoluta,the experiments of trapping effects with different setting angles and heights of blue sticky cards with sex pheromone lure were carried out.The results showed that both the different angles and heights of the blue sticky cards had great effects on the numbers of trapped moths.The average number of moths of blue sticky cards in flat was 1.438 times and 8.590 times,compared to that in 45°-inclined to the ground and 90°-inclined(blue cards placed vertically on the ground),respectively;and the significant differences were both existed between the flatted and vertical,45°-inclined and vertical treatments.As for the different laying height,the average trapped moths in 0 cm treatment was 1.491 times and 2.485 times,compared to the heights 30-35 cm and 60-65 cm,respectively,with a significant difference between the height 0 cm and 60-65 cm treatments.Therefore,it is recommended that the blue sticky cards are placed horizontally on the ground to get the higher trapping effects for T.absoluta in the field.
