本文研究了以矿物油(mineral spray oil)乳剂为保护剂、“猎蝇”蛋白质毒饵为诱杀剂组成的拒避-诱杀组合技术对橘小实蝇Bactrocera dorsalis (Hendel)产卵的控制作用。结果显示:橘小实蝇在采用拒避-诱杀组合技术保护的供试香蕉上平均产卵孔数为0.000±0.000个,果实完好率达到100%,而单独使用“猎蝇”蛋白质毒饵的平均产卵孔数为27.000±1.732个,果实完好率仅为5.55%,表明该组合技术对橘小实蝇产卵的控制效果显著。在100倍～300倍浓度范围内,矿物油浓度越高,拒避-诱杀组合对橘小实蝇产卵的控制效果越好;随着虫口密度的增加,毒饵使用量和施用面积也须相应增加,才能取得更好的防治效果。
In this paper, we studied the control effect of the combination of the anti-trapping and trapping combination of mineral spray oil as protective agent and the bait of “flies” on the spawning of Bactrocera dorsalis (Hendel) . The results showed that the average number of ova produced per hole on test bananas protected by the combination of rejection and trapping techniques was 0.000 ± 0.000 and the intact rate of fruit reached 100%, while the fruit poisoning bait The average number of spawning holes was 27.000 ± 1.732, and the rate of intact fruit was only 5.55%, indicating that this combination technique has significant control effect on oviposition of Trichodina ficus. In the concentration range of 100 times to 300 times, the higher the concentration of mineral oil, the better the control effect of the combination of rejection-trapping and killing on the oviposition of Trichosanthes flies; with the increase of population density, the dosage of bait and application area should also be corresponding Increase in order to achieve better control effect.
