花蓟马(Frankiniella　bispinosa)的室内饲养方法（英文）

Rearing Frankliniella bispinosa (Thysanoptera: Thripidae)on Plant Pollen in Laboratory

本文提出一种在室内用植物花粉饲养蓟马的方法，幼虫可在离体植物叶片上饲以花粉，以便观察记录，化蛹前移自小瓶内，老熟幼虫在两层纸片间化蛹。成虫在透明的小瓶内饲养，以花粉为饲料，用两层巴尔膜中间夹水封住小瓶的开口，作为蓟马的产卵场所。试验结果表明：香蒲（TyPhadomingensis）花粉最为合适，幼虫存活率达80％，成虫寿命为23．34天，平均每雌产卵量高达123．2粒，种群趋势指数达46．2。

A new method for rearing Frankliniella bispinosa using plant pollen in laboratory was reported inthis paper. The results indicated that cattail (Typal domingearis) pollen is the best food compared with the pollens of Phienix roebelenii, Pinus elliottii and Bidens pinosa. New larvae took shout nine days to develop to adultwith the survival rate of 80. 0% and the adult longevity was 23. 34 days. An average of 123. 2 eggs per femalewas obtained compared with less than 40 eggs on other three pollens. The population trend index on cattailpollen reached 46. 2, much higher than those on other three pollens.
