[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.
