摘要
[Objective] The aim of this study was to select an efficient and non-pol-luting method to kil the larva of fruit fly in citrus. [Method] The larvae of Bactrocera minax in citrus fruits were suffocated using plastic bags with or without a certain concentration of pesticide. Then, the mortality of in different treatments was measured 24, 48, 60, 240 and 480 h later. Final y, variance analysis was carried out. [Result] There was no significant difference in the mortality between the two treatments： suffocating the larvae with sealed plastic bags containing no or a certain concentration of pesticide 5 d. later. The former had high mortality, but also was economic and without any pol ution. The orange maggots were more easier to be kil ed in sealed plastic bags. [Conclusion] Suffocating orange maggots with no-insec-ticide plastic bag is economic, efficient and has no pol ution to the environment.
[目的]探索经济、高效、无污染的杀死柑桔大实蝇幼虫的科学方法。[方法]选择塑料袋加某一浓度的杀虫剂和不加杀虫剂闷处柑桔大实蝇幼虫的方法,得出幼虫死亡数据,并进行方差分析。[结果]处理5 d后,塑料袋封口不加药处理和塑料袋封口加药处理幼虫死亡率无明显差异;与加药不封闭处理相比,在隔绝空气的条件下更易杀死柑桔大实蝇幼虫。[结论]塑料袋封口不加药处理更经济有效,且不污染环境。
