摘　　要：】调查研究表明，四川省果蔬实蝇共１２种，属于寡毛实蝇属（Ｄａｃｕｓ）的９种，大实蝇属（Ｔｅｔｒａｄａｃｕｓ）的２种和棍腹实蝇属（Ｃａｌａｎｔｒａｅ）的１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类。即盆地中亚热带生态地理分布区，盆地边缘北亚热带生态地理分布区，川西南山地南亚热带生态地理分布区，川西山原暖温带生态地理分布区和川西北高原寒温带生态地理分布区。川西南山地南亚热带生态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。在川西山原暖温带生态地理分布区和川西北高原寒温带生态地理分布区未发现有果蔬实蝇分布。A survey conducted in 1992～1993 revealed that of the 6000 odd specimens collected, 12 species belonging to the genera Dacus (9 species), Tetraducus (2 species) and Callantrae (1 species) were identified. According to the climatic and geographical contions, their eco geographical distribution was divided into five districts: the subtropical district within the Sichuan Basin, the hilly area distribution district at the northern boundary of the basin, the mountainous region distribution district of southwestern Sichuan, the mountainous region distribution district of western Sichuan and the plateau distribution district of northwestern Sichuan. The species of fruit fly were found to be most plentiful in the mountainous region distribution district of southwestern Sichuan, followed by the subtropical district with the basin. No fruit flies attacking fruits and vegetables were discovered in the mountainous region distribution district of western Sichuan and the plateau distribution district of northwestern Sichuan.
