草麻黄提取物对小菜蛾幼虫的拒食活性研究 - The parasitized dbm larvae had prolonged their 4th instar duration obviously , and the later the larva had been parasitized , the longer this extended duration became
小菜蛾幼虫被寄生后，其4龄发育历期较未被寄生的显著长，且寄生时龄期越大4龄历期延长越多。 - The toxicity of 5 % chlorfluazuron , 4 . 5 % beta - cypemethrin and the different mixtures of 5 % chlorfluazuron and 4 . 5 % beta - cypemethrin to plutella xylostella larvae was determined by leaf immersion method under laboratory condition
摘要采用浸叶法在室内条件下测定5 %定虫隆、 4 . 5 %高效氯氰菊酯单剂以及不同配比混剂对小菜蛾幼虫的毒力。 - The insect feeding test indicated that the development of lymantria dispar was clearly put off , in which the insects feeded transgenic plants were 2 ages , when the insects as the control were 4 ages after treating 15 days . besides , the insect growth was restrained , that the weight of insect as control was 9 . 7 and 6 . 4 times compared to the treated ones . it also resulted that the foreign gene could normally express in the transgenic plants by displaying insect resistance in a certain degrees
舞毒蛾幼虫发育推迟， 15天时处理为4龄，但对照仍为2龄，发育推迟了2个龄期；舞毒蛾生长受到抑制，对照的体重为处理的9 . 7倍与6 . 4倍，外源基因严重抑制幼虫的生长，说明外源基因在转基因白桦中能够正常表达，转基因植株表现一定的抗虫性。
