本文试验了杀螨利果、西斗星、三氯杀螨醇、螨虫素、爱及咪、蚜螨灵、克螨特、尼索朗等8种药剂对二斑叶螨TetranychusurticaeKoch卵、幼若螨和成螨的杀虫效果。结果表明,上述8种药剂中,杀螨利果效果最好,供试的3种浓度1500、2500和4000倍对各虫态螨均有较好的杀虫效果,死亡率可达100%;三氯杀螨醇、西斗星、爱及咪次之;螨虫素、蚜螨灵杀幼若螨和成螨效果较好,但杀卵效果较差,分别仅为30%和60%左右,克螨特对各虫态的效果均较差,且作用较为缓慢;尼索朗杀成螨效果较差,不及50%,杀幼若螨效果一般,稀释1000倍液对幼若螨的死亡率为90%左右,但它具有很强的杀卵作用,用1000倍和2000倍液处理二斑叶螨卵,其死亡率均为99%以上,是一种较好的杀卵剂
In this paper, eight kinds of spider mite Tetranychusurticae Koch eggs, juvenile nymphs and adult mites were tested for eight kinds of insecticides such as acaroid, western bullfight, dicofol, mite, amygdalone, Insecticidal effect. The results showed that among the above eight kinds of medicaments, acaricide and fructus was the best, with 1500, 2500 and 4000 times of the three tested concentrations of mite and mite, all of which had good insecticidal effect and the mortality rate reached 100%; dicofol , Caterpillar fungus, love and microphone times; mite, aphid mites kill young nymphs and adult mites better, but the killing effect is poor, respectively, only 30% and 60%, respectively, The results showed that the effect of nymphs was poor, and the effect was slow. Nisolone killed less than 50% of the mites, killing the nymphs in general had the same effect. The mortality rate of the nymphs was about 90% However, it has a strong ovicidal effect, with 1000 times and 2000 times the liquid two-spotted spider mite eggs, the mortality rate was 99% or more, is a better ovicide
