为大量采集和鉴定冈田氏绕眼果蝇。特将水果 (苹果、梨等 )切碎经发酵后 ,打成包并悬挂于树干 ,吸引果蝇进行诱捕或者置入蚊帐内诱捕。自 1 989~ 2 0 0 0年 9月经过数次现场实验 ,均可大量捕获冈田氏绕眼果蝇。依据该种果蝇的形态结构和行为特征进行种的鉴定 ,尤其是雄外生殖器的特征和冈田氏绕眼果蝇腹部第 3~ 5节的背面各有一似“山”形黑褐色斑纹及足的胫节上 ,有 3个黑褐色环以及雄性生殖器的形态等可作为该种果蝇的外形特征
Okada’s Orbital flies were collected and identified extensively. Special fruit (apple, pear, etc.) chopped fermented, tied into a bag and hanging in the trunk, to attract fruit flies trap or trap into mosquito trap. After several field experiments from September 1989 to September 2007, Okada could be captured in large numbers. According to the morphological structure and behavioral characteristics of Drosophila species identification, especially male genitalia and Okada’s eye around the dorsal sections 3-5 section of a similar “mountain” shaped dark brown markings and Feet tibia, there are 3 dark brown rings and male genital morphology can be used as the shape characteristics of the fruit fly
