温室白粉虱(Trialeurodes vaporariorum Westwood)是世界性害虫。在我国近年来才出现的,我区于1976年首先在新城大队温室发现此虫,1977年造成严重为害。两年多来,我们对其生物学特性进行了初步观察,并做了一些防治试验。 形态特征 温室白粉虱属半翅目、同翅亚目、粉虱科(Aleyrodidae),因成虫体表布有白色蜡粉,故名粉虱。成虫、幼虫和蛹腹末端背部都有一个皿状孔,是此科昆虫的主要识别特征(图1)。 成虫 体长1.1—1.2毫米(计量单位以下均同)。翅展2.3。触角短丝状,6节(有的报道为7节)(图2B)。复眼肾形,暗红色。喙针状,较粗,末端略膨大且色暗。各足基节膨大凸出,跗节2—2—2,端部具爪。腹部第一节细缩,呈柄状。雌雄均有膜质翅二对,前后翅上各有一条翅脉。雄虫略
Trialeurodes vaporariorum Westwood is a worldwide pest. In our country only appeared in recent years, our district first discovered this pest in greenhouse of New City Brigade in 1976, causing serious damage in 1977. Over the past two years, we have made preliminary observations on its biological characteristics and made some prevention and control tests. Morphological characteristics Whitefly genus Hemiptera, homopteran, Whitefly (Aleyrodidae), due to adult body surface cloth with white wax, so named whitefly. Adults, larvae and pupae at the end of the dorsal abdomen have a dish-shaped hole, is the main identification features of insects (Figure 1). Adult body length 1.1-1.2 mm (the same units of measurement). Wing Show 2.3. Antenna short filamentous, 6 (some reported as 7) (Figure 2B). Compound kidney kidney, dark red. Beak acicular, coarser, slightly enlarged terminal and dark color. Each foot base bulging bulge, section 2-2-2, the end claw. The first section of the abdomen abdomen, was a handle. Both male and female membranous wings two pairs, before and after each wing has a veins. Male insect slightly
