Floyd(1921)在将近60年前,首次记载了温室白粉虱Trialeurodes vaporariorum(westwood)对黄色和黄绿色的强烈趋性。他报导大量粉虱成虫粘着在盛有色溶液的容器中。近年来,用能产生不同波长光的仪器进行了几次观察。结果表明,对光反应最大,是在520—610nm(毫微米)波长的黄绿色光区(Vaishampayan1973,Vaishampayan et al.1975a,1975b);对寄主植物的选择(如果不是仅仅只有一种寄主植物的话),主要是对颜色的反应。MacDowall(1972)用单色光进行了研究,他指出对白粉虱的最大吸引力是在540-550nm波长的光区。Kring(1969,未发表)报导了有关温室白粉虱和它常见的寄生蜂—丽蚜小蜂Encarsia formosa(Gahan)两者对黄色的趋性,以及把白粉虱诱集到粘的黄色板条上的试
Floyd (1921), for the first time nearly 60 years ago, documented the strong tropism toward yellow and yellow-green in Trialeurodes vaporariorum (westwood). He reported that a large number of whitefly adults cling to containers of colored solutions. In recent years several observations have been made with instruments capable of producing light of different wavelengths. The results showed that the response to light was maximal with yellow-green light at a wavelength of 520-610 nm (Vaishampayan 1973, Vaishampayan et al. 1975a, 1975b); selection of the host plant (if not only for one host plant ), Mainly on the color reaction. MacDowall (1972) studied monochromatic light and pointed out that the greatest attraction for whiteflies is in the 540-550 nm wavelength region. Kring (1969, unpublished) reported the yellow-to-green tropism for B. tabaci and its common parasitic wasser, Encarsia formosa (Gahan), and trapping B. tabaci on sticky yellow slats Test
