在室内研究了3种橘小实蝇幼虫寄生蜂切割潜蝇茧蜂、凡氏费氏茧蜂与长尾全裂茧蜂的竞争关系。结果表明，当寄生蜂数量相同时，切割潜蝇茧蜂或凡氏费氏茧蜂与长尾全裂茧蜂共同寄生橘小实蝇时，长尾全裂茧蜂的单头平均寄生率均占绝对优势，分别为13.5%、13.1%。寄生蜂数量不同且切割潜蝇茧蜂或凡氏费氏茧蜂的数量为长尾全裂茧蜂的2倍时，长尾全裂茧蜂单头平均寄生率分别为19.7%、18.4%，而切割潜蝇茧蜂和凡氏费氏茧蜂的单头平均寄生率分别为11.3%、9.7%，差异显著。当寄生蜂数量不同且长尾全裂茧蜂是切割潜蝇茧蜂或凡氏费氏茧蜂的2倍时，长尾全裂茧蜂的单头平均寄生率均为19.4%，而切割潜蝇茧蜂和凡氏费氏茧蜂的单头平均寄生率分别为7.6%、8.8%，差异显著。长尾全裂茧蜂的寄生率均显著高于其他2种蜂，长尾全裂茧蜂具有明显的竞争优势。

Interspecific competition among three parasitoids of Bactrocera dorsalis (Hendel) larvae, Diachasmimorpha longicaudata (Ashmead), Psyttalia incisi (Silvestri) and Fopius vandenboschi (Fullaway), was investigated at 26 ℃ in the laboratory. Results showed that parasitism rates per female D. longicaudata were 13.5%and 13.1%, significantly higher than those by P. incisi and F. vandenboschi, respectively, when the former was combined with each of the latter two at the same numbers. When twice number of P. incisi or F. vandenboschi was combined together with D. longicaudata, the parasitism rates per female D. longicaudata were 19.7% and 18.4%, respectively, while those of P. incisi and F. vandenboschi were 11.3% and 9.7%, respectively. When D. longicaudata was combined together with P. incisi or F. vandenboschi at a ratio of 2:1, the parasitism rates per female D. longicaudata were 19.4%, and the parasitism rates of P. incisi and F. vandenboschi were 7.6%and 8.8%, respectively. The results show that D. longicaudata has stronger competitive ability than the other two parasitoids species.
