杀螨的

Field experiments demonstrated that efficacy of 30% dichlorvos and omethoate for Caloptilia dentata was over 80%, for Drosicha corpulenta was 95.9% and Psylla willieti 96.4%. For Parathrene tabanifomis, Anoplophora glabripennis, Apriona swainsoni and Panonychus ulmi also gained perfected efficiency, and injection dosage of 2.0ml/cm φ for Myzus persicae obtained 100%result, for Eriococcus lagerostioemiae which damage Punica gianatum the result was 92.96%. In all, the efficiency of 30% diohlorvos · omethoate control of most pests was better than bisultap, decis, acephate, nicotine and avermectin, etc.

田间防效结果表明30%敌畏·氧乐对元宝枫细蛾的防治效果可以达到80%以上，对草履蚧和槐木虱防效分别大于95.9%和96.4%，对白杨透翅蛾幼虫、危害新疆杨和合作杨的光肩星天牛幼虫、危害国槐的锈色粒肩天牛幼虫、危害苹果的榆全爪螨等可达到理想防效，当施药剂量为2.0 ml/cmφ时对桃蚜的防效达100%，对危害石榴的紫薇绒蚧防效可达92.96%以上。30%敌畏·氧乐对大多数害虫的控制作用优于杀虫双、敌杀死、乙酰甲胺磷、烟碱和阿维菌素等。

Preliminary bioassays indicated that many title compounds exhibited excellent fungicidal, or insecticidal and acaricidal activities. The strobilurin derivatives containing substituted pyrimide ring have lower biological activity than the strobilurin derivatives containing substituted pyrazole ring which exhibited good fungicidal activity against RB (0.92 mg/L), TLB (0.3 mg/L), CDM (12.5 mg/L) and WPM (1.56 mg/L).

初步生物活性测定结果表明，新型Strobilurin类化合物中多个化合物具有较好的杀菌或杀虫杀加热管螨活性，其中吡唑类化合物要明显优于嘧啶类化合物，吡唑类化合物在低浓加热管度下对水稻稻瘟病菌(0.92 mg/L)、番茄晚疫病菌(0.3 mg/L)、黄瓜霜霉病(12.5 mg/L)和小加热管麦白粉病(1.56 mg/L)仍具有很好的杀菌活性。

The results showed that Lufenuron possessed high ovicidal activity on H.armigera 1-day eggs at 50 mg/L,eggs mortality rate was 87.30%;LC50 of stomach poisoning of 2nd ～ 5st instar larvae were 0.7434 mg/L,1.9669 mg/L,2.0592 mg/L and 2.6945 mg/L with leaf dipping method,respectively.

结果表明，虱螨脲具有较强的杀卵作用，在50 mg/L浓度下，棉铃虫1日龄卵死亡率达到87.30%；对棉铃虫2~5龄幼虫具有较高的胃毒活性，其LC50分别为0.743 4 mg/L、1.966 9 mg/L、2.059 2 mg/L和2.694 5 mg/L。

Avermectin are 16-membered pentacyclic lactone compounds produced by Strephomyces avermitilis, which have extensive and high effect on many kinds of insect and mite.

阿维菌素是从阿维链霉菌的发酵产物中分离出来的16元大环内酯类抗生素，对多种动物寄生虫及农业害虫害螨有很高的杀虫活性，但是该药剂光照易降解而持效期短。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
