查询词典 lepidopterous

Bioassay results at the laboratory showed that HNPC-A2005 had good stomach, contact, comprehensive action and a weak systemic activity to the lepidopterous insects such as oriental armyworm Mythimna separata and imported cabbageworm Pieris rapae. Quick knockdown action was also observed during the experiment.

室内生测结果表明，HNPC-A2005对粘虫和菜青虫等害虫具有优异的胃毒、触杀和综合毒力，且在试验过程中还发现该化合物具有对昆虫击倒快的特点，但内吸作用较弱。

G. lepidopterous eggs . Although tens of species have been formally identified in China, species identification is still a specialized, time consuming and difficult task, especially for arrhenotokous forms.

尽管我国正式发表的赤眼蜂已有数十种，但鉴定工作一直是一项费时费力、需要专门培训的技术，而对于产雌孤雌生殖型的鉴定则更为复杂。

Toxicity, mode of action and field efficacy of HNPC-A2005 was evaluated against the lepidopterous insects.

在此，就新农药HNPC-A2005对鳞翅目昆虫的杀虫活性及田间防治效果进行了研究。

The homologues of ptp-1 and ptp-2 genes were found in some lepidopterous baculoviruses, but not in non-lepidopterous baculoviruses. ApNPV was one of the four baculoviruses contained both ptp-1 and ptp-2 genes.

只有部分鳞翅目杆状病毒编码ptp-1、ptp-2基因同源区，非鳞翅目杆状病毒不编码ptp-1、ptp-2基因同源区，而ApNPV为鳞翅目杆状病毒，同时编码ptp-1、ptp-2基因同源区。

The biological safety of Bacillus thuringiensis Strain YJ-2000 which acted the low toxicity to Bombyx mori newly hatched larvae and marked insecticidal activity to other lepidopterous insects was evaluated compared with other two Bt strains,i.e.

YJ 2 0 0 0菌株除导致 1龄幼虫历期延长 11 1%、取食量减少 0～ 6 0 0 %及体重降低 5 2 3%～ 6 2 5 %外，对 2龄及其以后各龄幼虫的存活率、发育历期、取食量、眠蚕体重、化蛹率、蛹期、全茧量、蛹重、茧层量、羽化率和产卵量等均无显著影响。

Results show that the insect community structure in the Bt fields differed sharply from that in the CV fields. The populations of the Lepidopterous pests, such as cotton bollworm, corn borer, diamond bollworm and cotton leaf caterpillar, decreased significantly in the BT fields, while the populations of non-target pests with piercing-sucking mouthparts, such as leaf bugs, cotton spider mites, cotton aphids and whiteflies, increased obviously. Much more predators, such as spiders and ladybirds, and much less parasitiods of Helicoverpa armigera were observed in the BT fields.

结果表明，与常规棉田相比，Bt棉田棉铃虫、玉米螟、金刚钻、棉小造桥虫等鳞翅目害虫种群数量显著降低，而盲蝽象、红蜘蛛、棉蚜、烟粉虱等非靶标刺吸式害虫种群数量显著增加；蜘蛛、瓢虫等捕食性天敌种群数量显著增加，而棉铃虫的寄生性天敌种群数量则显著下降。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
