| 经室内毒力测定证明:虫螨磷与氰戊菊酯(3:1)混用,共毒系数(CTC)达972.1,有显著增效作用。增效磷(SV_1)与氰戊菊酯(5:1)混用有一定增效作用(CTC=274.6)。噻嗪酮的 LC50o值为0.01272ppm,毒力明显高于氰戊菊酯(LC50为475.77ppm),两者混用(5:1)时 CTC 为356.2,倍硫磷与氰戊菊酯(5:1)混用 CTC 为708.4,均有明显增效作用。在农大小温室试验诱杀成虫证明用20×28.5cm~2黄板垂直挂在番茄植株顶部的支架上且黄板底边与植株顶部相平时效果最好。1987～1988两年在四季青温室番茄上对温室白粉虱的综合防治试验证明:在黄板的配合下,氰戊菊酯分别与虫螨磷和 SV1混用,其防治效果均在84.5%以上,前一种混剂更好在91.6%以上。而喷药次数只需2～3次。单用氰戊菊酯,对成虫和卵、若虫的防治效果1987年分别为95.5%和73.5%,1988年分别为75.3%和35.9%,明显低于混剂的防效。试验还证明,黄板加上噻嗪酮,不仅用药量小(5.685有效成分 g/ha),而且其防治效果在94.8%以上。与综合防治相比,只用农药的常规防治法效... |

| Abstract: |
| Synergistic actions of insecticide mixtures to the glasshouse whi- tefly [Trialeurodes vaporariorum(Westw.)] were evaluated in the laboratory. Results showed that fenvalerate were significantly synergisted by some organo- phosphorus insecticides,such as Pirimiphos-methyl,fenthion and SV1(O,O-diethyl- O-phenyl phosphorothionate),the CTC values were 972.1;708.8 and 274.6 respec- tively.And the mixture of buprofezin with fenvalerate also had a high synergistic action (CTC:356.2). Yellow plate (wave length abo... |
