  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.

For selection of resistant strains, every generation of the peanut aphid native from Taian was treated by dipping with three insecticides individually and one mixed agent. Up to the 16th generation, the omethoate-selected strain had no resistance, but the methomyl alone and in combination with omethoate (AI 1:2) selected strains had 19.7 and 11.4 fold resistance respectively. The resistance of the deltamethrin-selected strain increased to 113.9 times at the 12th generation. The later three resistant strains...

For selection of resistant strains, every generation of the peanut aphid native from Taian was treated by dipping with three insecticides individually and one mixed agent. Up to the 16th generation, the omethoate-selected strain had no resistance, but the methomyl alone and in combination with omethoate (AI 1:2) selected strains had 19.7 and 11.4 fold resistance respectively. The resistance of the deltamethrin-selected strain increased to 113.9 times at the 12th generation. The later three resistant strains showed cross-resistance at high or low level to deltamethrin, methomyl and the mixture and no significant cross-resistance to other seven organophosphorus insecticides tested. The bioassay with an enzyme inhibitor, determination of enzyme activity in vitro and analysis of esterase isozymes revealed that the resistance of the peanut aphid to methomyl was related to hydrolytic metabolism, and the resistance to deltamethrin related to hydrolytic and oxidative metabolism.

用3种杀虫剂及1种混剂对山东泰安花生蚜累代浸蘸处理,以选育抗药性品系。至16代,该虫对氧乐果未产生明显抗(?),对灭多威及氧乐果+灭多威(Al 2∶1)混剂抗性分别为19.7倍及11.4倍,而溴氰菊酯处理至12代抗性却高达113.9倍。上述后3个抗性品系对溴氰菊酯、灭多威及混剂存在高度或低(?)交互抗性,而对7种有机磷杀虫剂交互抗性不明显。经酶抑制剂生测、离体酶活性测定及同工酶谱分析,花生蚜对灭多威的抗性与水解代谢有关,对溴氰菊酯的抗性与水解和氧化代谢有关。

Pinnapis baxi is considered to be one of the most important pest to ornamental plants in our country. Because the insect body has the wax Substance that block the insecticides (usually sprayed),there were Some difficulties in controlling it. In 1992,the tests of the effectiveness and control methods were carried out in Linfen prefection using Cerocide (a new insecticide that can resolves the wax ), Omethoate and methomyl for the control to the pest, which attacks chines ilex. Results showed that the stages of the development of the hibernate adult in spring and first instar larvae were better periods for the control and Cerocide and Omethoate were very effective.

黄杨并盾蚧是我国园林绿化植物的一种主要害虫。由于该虫身被蜡质,防治困难。1992年应用蜡蚧灵等3种化学农药进行了防治技术研究和药效试验,结果表明:越冬雌成虫活动期和一代若虫出壳盛末期是防治最佳时期,蜡蚧灵和氧化乐果是比较理想的防治药剂。
