  methomyl
The interaction of pesticides with humic compounds (humic and fulvic acids) and with their metal complexes was studied potentiometrically and radiometrically, using the pesticides Aldicarb and Methomyl, and the herbicide Ametryne.
      
The results indicated that Aldicarb, Methomyl, and Ametryne form stable complexes with humic acid (HA) and fulvic acid (FA).
      
The complexation strength increases in the order Aldicarb ≤ Methomyl >amp;lt; Ametryne.
      
The complexes of Aldicarb and Methomyl with HA and FA are stronger than the metal humate/fulvate complexes with Co2+, Zn2+, and Sr2+, and these pesticides displace the metal ions.
      
The complexation of Aldicarb and Methomyl with humic compounds causes the release of radionuclides (60Co, 65Zn, 90Sr) from the soil organic matter to the solution.

In 1991 and 1993, two bioassays for insecticide toxicity were made to study the resistance changes of diamond back moth which were collected from six main vegetable production areas including Guiyang, Zunyi,Anshun, Duyun, Tongren and Bijie of Guizhou Province. The results indicated; within the three years,Guiyang strain increased the resistance to dimehypo as much as 32.5 times, the other strains showed high sensitivity to this insecticide. All six strains were highly sensitive to DDVP. The two strains of Guiyang...

In 1991 and 1993, two bioassays for insecticide toxicity were made to study the resistance changes of diamond back moth which were collected from six main vegetable production areas including Guiyang, Zunyi,Anshun, Duyun, Tongren and Bijie of Guizhou Province. The results indicated; within the three years,Guiyang strain increased the resistance to dimehypo as much as 32.5 times, the other strains showed high sensitivity to this insecticide. All six strains were highly sensitive to DDVP. The two strains of Guiyang and Anshun produced very high resistance to deltamethrin and their resistances went up to 1124 and 558 folds,and other strain had no remarkable resistance. The cross resistances of dimehypo resistant strain(the 30th and 70th generations selected in laboratory)were revealed by bioassays made in 1991 and 1994. The result showed that the resistant strain showed significant positive cross resistance to the same type of insecticides such as cartap, light posistive or negative resistances to DDVP (organophosphorus), deltamethrin (pyrethroids),methomyl (carbamate),and Bt (microbic insecticide). The field control experiments demonstrated that dimehypo had a comparatively satisfied effect and mixing this insecticide with Bt or abametin could control diamondback moth better.

抗药性监测结果表明,三年来贵阳小菜蛾种群对杀虫及的抗性增长23.5倍;其余各地种群仍有较高的敏感性;对敌敌畏各地种群仍有较高的敏感性,抗性不明显;对溴氰菊酯贵阳、安顺种群产生了高度抗性,与敏感品系比较抗性分别增长1124倍和558倍,其余各地种群对溴氰菊68仍有较高的敏感性,抗性不明显。交互抗性测定结果表明:抗杀虫双品系对同类药剂杀螟丹有明显的正交互抗性;对敌敌畏、溴氰菊酯、灭多威和苏云金杆菌等的敏感度较高。田间防治试验结果表明,杀虫双仍有较高的防治效果,苏云金杆菌和螨虫素与杀虫双混用可明显提高防治效果。

The period required for the whole embryonic development of Chrysopa seplempunctata(Wesmael), at 27℃ constant temperature and 80% relative humidity, is about seventy to eighty hours. Accoding to the morphological feature of the embryo, the whole period can be divided into five developmental stages including the early developmental stage: the germ band expanding stage; the embryo contracting stage; the embryo's further expanding and dorsal closure stage; and the embryo maturing stage. The experamental results...

在27℃恒温和80%相对湿度条件下,大草蛉胚胎发育的全历期为70~80h。根据其胚胎形态特征可将整个发育期分为5个发育阶段:早期发育阶段、胚带伸长阶段、胚胎缩短阶段、胚胎再伸长及背合阶段、胚胎成熟阶段。4种杀虫剂对大草蛉胚胎发育前期(10h)、中期(30h)、和后期(60h)的杀卵试验表明:4种杀虫剂的杀卵作用均随胚胎发育时间的增加而提高,其中以功夫菊酯的杀卵作用最强,其次为灭多威、久效磷,抗蚜威的杀卵作用最弱。

Five pesticides against Thrips palmi Karny were tested in the field. The results showed that carbofuran (20%EC)and alphacypermethrin (2. 5%EC) were highly effective on both adults and larvae of thrips. Methomyl (24%)and isoprocarb (20%EC) were moderately effective,while dimethoate (40%EC) resulted in low effectiveness. In order to get good effectiveness of control with pesticides against Thrips palmi,the strategy of applying twice within 4 to 6 days was suggested.

对5种药剂防治节瓜蓟马进行了田间试验。试验结果表明,丁硫克百威对节瓜蓟马防治效果最好,建议使用倍数为1000~1500倍;其次是顺式氟氰菊酯。灭多威、异丙威对节瓜蓟马防治效果一般,而乐果防治效果最差。本文提出了在用药剂防治节瓜蓟马过程中宜采用在4~6天内连续施用二次药的使用策略。
