黑腹果蝇在杨梅园内的空间分布与防治初探

A preliminary Study on Spatial Distribution and Control of Drosophila Melanogaster in Poplar orchard

在杨梅果实生长阶段,比较了果蝇专用诱杀剂和黄板纸对黑腹果蝇成虫诱杀效果,在此基础上采取高、中、低三种不同高度处理,研究黑腹果蝇成虫在杨梅园内的空间分布情况。结果表明专用诱杀剂效果明显优于黄板纸,且离地高度为0.7m左右的距离诱杀效果最好。

During growth and development of waxberry fruit, trapping effect of special attractant and yellow paper on adult Drosophila melanogaster were compared. Based on comparison results, three treatments of different high degree（high, middle and low） were used to study spatial distribution of Drosophila melanogaster in poplar orchard. The results showed that trapping effect of special attractant surpassed that of yellow paper and trapping effect was best when special attractant was about 0.7 m high over the earth.
