摘　　要：报道了1997～2001年用Me、Cue、Tri三种实蝇信息素和水解蛋白在四川47县(市、区)341个点的田间诱捕监测实蝇的种类发生和地理分布的结果。监测结果表明,共收集到实蝇标本15277个,分属于离腹寡毛实蝇属(BactroceraMacquart)的8个种和合腹寡毛实蝇属(DacusFabricius)属的1个种,其中发现新记录种2种。根据气候和地理条件等特点和实蝇区系种类组成,可将四川果蔬实蝇的生态地理分布分为5个类型,即盆地中亚热带地理分布区、盆地边缘北亚热带地理分布区、川西南山地南亚热带地理分布区、川西山原暖温带地理分布区和川西北高原寒温带地理分布区。川西南山地南亚热带地理分布区的实蝇种类最丰富,其次是盆地中亚热带生态地理分布区。在川西山原暖温带地理分布区和川西北高原寒温带地理分布区未发现有果蔬实蝇分布。This paper reported the result of occurrence and geographical distribution of fruit flies infecting fruits and vegetables inspected with 3 pheromones and hydrolytic protein in Sichuan.The studies conducted in 1997-2001 revealed that of the 15 277odd specimens collected,9 species belonging to the genera Bactrcera (8 species),Dacus (1 species) were identified,and 2 species of them were newly recorded.According to the climate and geographical conditions,their ecogeographical distribution was divided into five districts:the subtropical district within the Sichuan Basin,the hilly area distribution district with north subtropical climate at the boundary of the basin,the mountainous region distribution district of southwestern Sichuan with south subtropical climate,the mountainous region distribution district of western Sichuan with warm temperate zone climate and the plateau distribution district of northwestern Sichuan with frigid temperate zone climate.The species of fruit fly were found to be the most plentiful in the mountainous region distribution district of southwestern Sichuan with south subtropical climate,followed by the subtropical district within the Sichuan Basin.No fruit flies attacking fruits and vegetables were discovered in the mountainous region distribution district of western Sichuan with warm temperate zone climate and the plateau distribution district of northwestern Sichuan with frigid temperate zone climate.
