The results showed that the trapping effect was enhanced when the hanging height was increased, and the trapping effect was the best in west direction. The trapping effect was enhanced when the dosage was increased. When it was up to 6 lures, the trapping effect was the best with 38.75 head/trap; the next was 2 lures with 31.00 head/trap. All types of traps had trapping ability to G. mo- lesta, among which triangle trapper was the best, followed by self-made bottle trap. Their trapping effects were 138.75 and 100.25 head/trap, respectively.展开更多
