摘要: 在恒温26~C,相对湿度70%的条件下,研究了烟粉虱Bemisia tabaci(Gennadius)卵柄的吸收作用。首先研究了含有农药的人工膜系统上卵的发育及浸根于农药的植株上烟粉虱卵的发育,发现农药处理对烟粉虱卵的存活产生了明显的不利影响,加入农药的人工膜系统及农药浸根处理的植株上卵的存活率要显著低于对照处理。其次将甘蓝、黄瓜、茄子、辣椒及玉米作为寄主植物,研究不同寄主植物上所产卵的发育历期及存活率,发现不同寄主植物上所产的卵的发育历期存在着显著差异,在供试的几种植物中,历期从长到短依次为甘蓝>黄瓜>茄子>辣椒>玉米,不同植株上卵的存活率也有一定的差异,尤其是玉米上的卵存活率要极显著低于其它植株上发育的卵。通过将不同植株上的刚孵化的一若虫转移至共同的其它的植株上后,不同来源的卵所孵化的一龄若虫的历期也有所不同,一龄若虫历期长短为,辣椒>甘蓝>黄瓜>茄子。以上现象说明产卵介质中的物质通过卵柄进入了烟粉虱的卵内,影响了卵及一龄若虫的发育。

Abstract: On the controlled condition of 26℃ and RH 70% ,we investigated the absorption function of the egg pedicel of tobacco whitefly,Bemisia tabaci(Gennadius)(Homoptera:Ahyrodidae).Firstly,we studied the efect of pesticide on development of egg laid on the artifical membrane apparatus and on plant which root was immersed in pesticide.As a result,we found the disadvantage of pesticide on development of whitefly eggs significantly,the eggs on artifical membrane with pesticide were dead entirely,but eggs development well on control,Secondly,we investigated the effect of different
plants on develolmlent of egg,results showed that there were significant difference on survival and development duration on eggs ovipesit on different plants,and the sequence of plants on which the survival of eggs from high to low was cabbage>cucumber>capsicum>eggplant>corn, the sequence of plants on which development duration of egg from long to short was cabbage>cucumber>eggplant>capsicum>corn.Lastly, we transferred the 1st larva which hatched from the eggs laid on the above different plant to the other common plant,tomato plant,and observed their development,the result showed that the duration sequence of 1st instar from long to short was on apsieum>cabbage>cucumber>eggplant.It is sugested that the substance ofmedium entered into the egg through whitefly egg pedicel,and it affect the development of whitefly egg and the following 1st larva.
