The high insecticidal efficacy of fenitrothion to wheat aphids(mainly Sitobion avenae(F.) and Schisaphis graminum(Rond.)) has been revealed from 20 candidate pesticides under laboratory evaluation studies conducted in 1983-1986. Promising control of aphids at different parts of wheat plant could be achieved, and the efficacies were correlated with the deposition rate of fenitrothion. A total extension area of about 7000 ha in Hebei, Gansu, Sichuan, Henan Provinces and Beijing suburb during 1985-1986 have...

The high insecticidal efficacy of fenitrothion to wheat aphids(mainly Sitobion avenae(F.) and Schisaphis graminum(Rond.)) has been revealed from 20 candidate pesticides under laboratory evaluation studies conducted in 1983-1986. Promising control of aphids at different parts of wheat plant could be achieved, and the efficacies were correlated with the deposition rate of fenitrothion. A total extension area of about 7000 ha in Hebei, Gansu, Sichuan, Henan Provinces and Beijing suburb during 1985-1986 have been treated with fenitrothion to control wheat aphids, under an application rate of 0.45 1/ha(50EC) and a control efficacy of higher than 90% was achieved with whatever spray methods, such as conventional sprayer, mist blower, low volume or ultra low volume application, were used. Considering that fenitrothion is a very promising insecticide and is going to be put into quantity production, it is suggested to be a good candidate aphicide on wheat.

1983—1986年通过室内毒力测定比较,在20种供试农药中筛选出杀螟松对麦蚜具有很高毒力,田间试验和示范表明,小麦不同部位农药沉积量同药效呈正相关,杀螟松对小麦各部位的蚜虫均有良好防效。1985—1986年在京、冀、甘、川、豫等省示范和推广10多万亩,每亩用50%乳油30毫升,无论用高容量、低容量、超低容量或吹雾法喷雾,防效均在90%以上。杀螟松是我国正在发展的大吨位农药品种,具有防效好、药源广、成本低、对人畜安全、无残毒等优点。作者认为是值得推荐的防治麦蚜的农药品种。

The LD_50 of Imidacloprid (technicalImidacloprid>96%) for contact activity against the 3rd and the 5th instarnymphs of BPH was 2.55×10-5 μg/nymph and 6.78×10-5μg/nymph respectively.Regressions of mortality probit (Y) against log10 of contact concentration (X) ofthe 3rd and the 5th instar nymphs were Y=5.6231 + 1.0486X and Y= 5.2091 +1.2389X respectively.Imidacloprid did not show only as a highly contact insecticide but also an excellent stomach toxicant against young and mature nymphs andadults of BPH. Field trials of foliar application in paddy fields of Jurong andWujiang Counties with 10% Imidacloprid WP,at a rate of 15 or 30g a.i./hm2.against BPH,achieved stably high (> 90% control effectiveness) population suppression over 40 days after treatment.The high insecticidal efficacy withImidacloprid as foliar spray for BPH control in paddy fields was basicallymanifested into three effective aspects,including rapidity (1~3 days after treatment), sustainability (4~10 days of treatment) and long residual effect (11 daysafter treatment).The field trials with Imidacloprid also displayed good selectivitybetween BPH and its natural enemies.It was specially safe to spider communityin paddy fields.

灭虫精(Imidacloprid通用名称吡虫啉)系一种内吸性杀虫剂,属硝基亚甲基化合物,对稻飞虱具有极强的生物活性。室内测定褐飞虱NilapavartalugensStal3龄与5龄若虫LD_50值分别为2.55×10-5μg/头与6.78×10-5μg/头,其毒力回归方程分别为Y=5.6231+1.0486X和Y=5.2091+1.2389X。实验表明,该药具有极好的触杀和胃毒作用,稻田应用的有效剂量为15~30g/hm~2,是扑虱灵常规用量的1/5~1/10。田间药效特征突出地表现为速效(1~3d)、持效(4~10d)和残效(11d以上)的三段效应,90%以上的防治效果可维持在40d以上。试验还表明,灭虫精田间应用表现出在飞虱和天敌之间的良好选择性,对稻田益蛛基本无害,是一种很有前途的稻田应用杀虫剂。

Hexaflumuron is a new insecticide belonging to the benzoylurea group.The biological activity was tested in laboratory. High insecticidal efficacy and ovicidal activity were observed. Results of field trials showed that hexaflumuron was effective against a number of agriculturally insect species,such as oriental armyworm,cotton bollworm,diamond backmoth, imported cabbageworm,citrus leafminer,beet armyworm et c.

氟铃脲为新型酰基脲类杀虫剂,室内研究表明其有较高的杀幼虫活性和杀卵活性,并有抑制取食作用。在田间进行了防治多种害虫的小区药效试验,在所设剂量下,可以控制害虫为害,对天敌有一定的选择保护作用,从害虫抗性治理、减少用药污染的角度看,氟铃脲具有很好的开发前景和应用价值。
