The rice striped stem borer (SSB), Chilo suppressalis (Walker), which is one of the most economically important phytophagous pests, has developed resistance to multiple insecticides. SSB against chlorantraniliprole been investigated in detail. However, mechanism its metabolic rarely studied.A field population from Wuhu City, China was used establish resistant and susceptible strains (WHR WHS) by laboratory continuous selection. Enzyme activities data suggested potential involvement...
The anthranilic diamide insecticide chlorantraniliprole is highly effective against Lepidoptera pests, but the underlying mechanisms of toxic effects exposures for adapting to chemical environment are poorly known in fall armyworm (FAW), Spodoptera frugiperda (J.E.Smith). FAW being one most pests maize Latin America, suddenly appeared China 2019 and spread rapidly. In this study, using bioassay transcriptomic biochemical analyses, we comprehensively investigated gene expression changes third...
为延缓阿维菌素的光解, 研究了不同浓度抗氧化剂TBHQ对阿维菌素光解的影响, 并通过稻茎浸渍法测定其与阿维菌素混用后对灰飞虱的毒力。结果表明: 阿维菌素的光解行为符合化学反应一级动力学方程, 阿维菌素在太阳光下的光解速率小于紫外光下的光解速率; 在TBHQ抑制阿维菌素光解试验中, 其与阿维菌素比值为1︰1时, 阿维菌素的光解速率最小, 光解半衰期为11.81 h, 比不添加TBHQ在紫外光下的光解半衰期延长167.19%。室内生物测定结果表明, TBHQ与阿维菌素混用后对灰飞虱表现为增效作用; 经太阳光和紫外光光照3 h后, 加入TBHQ的阿维菌素对灰飞虱的毒力均显著高于未添加TBHQ的处理, 增效比分别为2.00和2.63。
通过室内生物测定、盆栽和田间试验, 研究了新型杀虫剂吡蚜酮对水稻褐飞虱的作用方式、不同龄期毒力、田间使用技术及防治效果, 并初步探讨了吡蚜酮对天敌黑肩绿盲蝽和蜘蛛(机敏漏斗蛛)的毒力及其田间数量的影响。结果表明: 吡蚜酮对褐飞虱不仅具有触杀作用, 还具有较强的内吸作用。吡蚜酮对褐飞虱1龄、3龄若虫的168 h LC50值分别为14.99 mg·L<sup>-1</sup>、13.08 mg·L<sup>-1</sup>, 显著低于5龄若虫和成虫。盆栽试验发现当盆钵中保持水层时, 吡蚜酮的防治效果更高。在褐飞虱低龄期、田间保持水层条件下, 应用25%吡蚜酮WP制剂300 g·hm<sup>-2</sup>、2、450 g?hm<sup>-2</sup>和600 g?hm<sup>-2</sup>, 药后15 d的防治效果可达95%以上。进一步的研究发现, 吡蚜酮对黑肩绿盲蝽成虫的安全性级别为较不安全(Ⅲ级), 田间使用吡蚜酮后黑肩绿盲蝽数量减少; 吡蚜酮对蜘蛛安全性级别为安全(Ⅰ级), 田间使用吡蚜酮后蜘蛛数量无明显变化。研究结果为吡蚜酮的合理使用提供了科学依据。
为探讨农药剂型对烟粉虱的毒力差异, 分别以甘蓝和黄瓜叶片作为生物测定载体, 比较了啶虫脒乳油(EC)、微乳剂(ME)、可溶性液剂(SL)、可溶性粉剂(SP)及可湿性粉剂(WP)等5种剂型对烟粉虱成虫的毒力, 并通过对植物叶片临界表面张力、啶虫脒药液表面张力、动态接触角及叶片持液量的测定, 分析了不同啶虫脒剂型间毒力差异形成的原因。结果表明: 以甘蓝叶片为生物测定载体, 不同啶虫脒剂型间对烟粉虱的毒力差异明显; 以黄瓜叶片为生物测定载体, 不同剂型间毒力差异不明显。啶虫脒SL、SP、WP在两种生物测定载体间的毒力差异大于EC和ME。甘蓝和黄瓜叶片的临界表面张力值分别为30.73 mN·m<sup>-1</sup>和57.91~63.30 mN·m<sup>-1</sup>。啶虫脒有效成分浓度大于7.81 mg·L<sup>-1</sup>时, 啶虫脒EC和ME溶液表面张力即小于甘蓝和黄瓜叶片的临界表面张力; 啶虫脒有效成分浓度大于500 啶虫脒SL、SP、WP溶液的表面张力才小于甘蓝叶片的临界表面张力。啶虫脒ME溶液液滴接触两种植物叶片的瞬间(0 s),...
