  monocrotophos
The results indicate that inhibition of AChE activity in fish exposed to monocrotophos may serve as an indicator of hazard due to application of this chemical in the natural environment.
      
In addition, four weeks following transfer to toxicant-free water after exposure to 1 mg monocrotophos, nile tilapia fish brain regained 95% of control AChE activity.
      
After 96 h exposure to acute levels of monocrotophos, the brain acetylcholinesterase (AChE) activity decreased progressively as the concentration of monocrotophos increased.
      
By probit analysis the 96 h LC50 value of monocrotophos was 4.9 mg/l.
      
The neurotoxic effects of monocrotophos on the brain of the nile tilapia fish (Oreochromis niloticus) were examined, using a static bioassay under laboratory conditions.

Laboratory and field tests showed that cotton aphides were very susceptible to pyrethroids e. g. deltamethrin, cypermethrin, flucythrinate, and fenvaterate. Their control effectiveness in the fields was marked. Smearing stems with monocrotophos slow-release-formutation was more effective than with omethoate. Seed dressing with methyl-phosfolan granule can control cotton aphides, but it has some inhibition of cotton growth in its early period.

室内试验和大田药效试验结果表明:棉蚜对拟除虫菊酯杀虫剂溴氰菊酯、氯氰菊醋、氟氰菊酯、杀灭菊酯十分敏感,大田防效显著。久效磷缓释剂涂茎对棉蚜的防治效果大于氧乐果。甲基硫环磷颗粒剂拌种可以防治棉蚜,但对棉花生长前期有些抑制作用。

The plant bugs, Lygus lucorum Mey-Dur and Adelphocoris suturalis Jak.have become important pests of cotton in Yangtze River valley since 1970's. These two species, occurring in various cotton growing stages simultaneously, infest the seedling leaves, squares and young bolls. Seedlings and young bolls are most seriously damaged, which may be killed or shed during young stages. Though no damage is caused when the population density is sufficiently low, it will increase steadily when the number of adults per 100...

The plant bugs, Lygus lucorum Mey-Dur and Adelphocoris suturalis Jak.have become important pests of cotton in Yangtze River valley since 1970's. These two species, occurring in various cotton growing stages simultaneously, infest the seedling leaves, squares and young bolls. Seedlings and young bolls are most seriously damaged, which may be killed or shed during young stages. Though no damage is caused when the population density is sufficiently low, it will increase steadily when the number of adults per 100 plants exceed 4. A regression analysis shows that when 5 bugs per 100 plants in 5-6 leavs stages and 10-12 bugs per 100 plants in squaring stage a spray of monocrotophos may be required.

本项研究以绿盲蝽(Lygus Lucorum Mey Dur)及中黑盲蝽(Adelphocoris Suturalis Jak.)为对象。棉花从子叶、真叶、现蕾到结铃各个阶段都能遭受棉盲蝽的为害。由于盲蝽成、若虫以刺吸口器刺伤幼嫩器官和生长点,使部份器官受到直接损伤并影响到棉株正常生长,导致减产。两种盲蝽不同种群数量在真叶期和蕾铃期为害造成籽花产量的损失均呈抛物型曲线。绿盲蝽在真叶期和蕾期为害,其经济阈限按防治费用与产量损失金额相等时,分别为百株有虫4.7头和12.57头,中黑盲蝽在蕾期的经济阈限为百株10.77头。据此,提出在真叶期及蕾期的防治指标依次为百株5头及10~12头。

The result of phytotoxicity experiments carried out in-door and in the field showed that phytotoxicity effects of 2.5% deltamethrin EC and other ten new pesticides on sorghum were weaker than that of trichlorfon. 50% monocrotophos EC and 50% phoxim EC were not applicable to sorghum. 40% acephate EC could he used on sorghum during initial jointing stage. Other pesticides had no phytotoxicity on sorghum and could normally be used.

1984年我们在校试验站,以2.5%溴氰菊酯乳油等10种新农药,对“黑歪”高梁进行了药害试验。通过室内和田间药害试验结果表明,2.5%溴氰菊酯乳油等新农药的药害都比敌百虫轻。50%久效磷乳油和50%辛硫磷乳油,因药害重不宜在高梁上施用。40%乙酰甲胺磷乳油可在开始拔节的高梁上施用。其他试验农药对供试高梁无药害,均可正常使用。
