杀螟松

对杀螟松的抗性试验用FAO滤纸药膜法进行，对氯化苦的抗性试验参照FAO磷化氢抗性测定法，在干燥器内熏蒸处理。

Fenitrothion resistance was determined using the impregnated paper assays ( FAO Method No.15 ), and chloropicrin resistance was tested by fumigation in desiccators .

另一些鱼在接触杀螟松之前分别用胡椒基丁醚（PBO）和磷酚三苯酯（TPP）做预处理。

Fish were also pretreated with piperonyl butoxide ( PBO ) or triphenyl phosphate ( TPP ) and then exposed to fenitrothion .

~（14）C标记农药杀螟松和马拉硫磷的制备

Preparation of ~ ( 14 ) C - sumithion and ~ ( 14 ) C-malathion

甲基对硫磷水解酶（MPH）除了可以降解甲基对硫磷外，还可以降解杀螟松，乙基对硫磷，毒死蜱，但降解效率依次降低。

Besides methyl parathion , MPH can also degrade fenitrothion , parathion , chlorpyrifos in degressive hydrolytic efficiency in turn .

从降解菌YF11中提取了降解酶并测定了该降解酶对对硫磷、甲基对硫磷和杀螟松的降解特性。

Degradation characteristics of parathion , parathion methyl and fenitrothion by a enzyme , extracted from the isolated strain YF11 , was determined .

在成虫盛发期用50%杀螟松、50%辛硫磷、50%马拉硫磷和40%乐果乳剂原液超低量喷雾，毒杀当代成虫及下代幼虫效果显著。

At the peaks of adult occurrence lower dosage sprays with 50 % Sumithion , 50 % Phoxim , 50 % Malathion and 40 % Dimethoate can give good results .

七种粘土粉末：硅镁土、埃洛石粉、膨润土、硅藻土、高岭土，滑石粉和稻壳灰被三种储粮保护剂：马拉硫磷、杀螟松和虫螨磷溶液浸泡。

Seven kinds of clay powder : attapulgite , halloysite , bentonite , diatomite , kaolin , talc and rice-hull ash were soaked in the protectant Solutions : malathion , fenitrothion and pirimiphos methyl .

使用50%杀螟松800倍液、1000倍液喷雾，防治初孵若虫，杀虫率分别可达96.9%、93.3%。

Spraying with 800 and 1 000 times liquid of 50 % fenitrothion to control the first instar nymphs , the death rates reached 96 . 9 % and 93 . 3 % respectively .
