| 中文摘要: |
| 储粮害虫作为对粮食造成品质降低和经济损失的重要因素，本研究选择昆虫生长调节剂S-烯虫酯进行防治。通过在实验室条件下模拟实仓害虫发生情况，对不同浓度和剂型的S-烯虫酯防治效果比较，选择适宜的S-烯虫酯进行实仓应用。研究结果表明，2.5、5 mg/kg质量浓度的S-烯虫酯（剂型I）对稻谷中的谷蠧成虫均能起到有效的控制作用，而且在2.5、5 mg/kg的剂量下能完全抑制谷蠧后代的产生。结合增效剂胡椒基丁醚（PBO）的S-烯虫酯（剂型II）能显著提升谷蠧成虫的死亡率。实仓实验结果表明，剂型II的S-烯虫酯对常见储粮害虫具有较强的致死效果，施用30天后谷蠧的校正死亡率为98.33%，赤拟谷盗的校正死亡率为99.33%，玉米象和长角扁谷盗的校正死亡率达到100%。综上所述，S-烯虫酯对于谷蠧的防治效果好，在实仓中应用也能对常见储粮害虫具有显著的控制作用。 |
| 英文摘要: |
| Stored grain pests, as an important factor causing quality degradation and economic loss to grain, were selected to be controlled by the insect growth regulator S-methoprene in this study. By simulating the occurrence of pests in real warehouses under laboratory conditions, the control effects of different concentrations and dosage forms of S-methoprene were compared, and the appropriate S-methoprene was selected for application in real warehouses. The results of the study showed that the concentrations of 2.5、5mg/kg of S-methoprene (Form I) were effective in controlling adult Rhyzopertha dominica（Fabricius） in rice grains, and When the dose of S-methoprene was 2.5、5mg/kg, the progeny production of R. dominica could be completely inhibited S-methoprene (Form II) in combination with the insecticide synergist piperonyl butoxide (PBO) significantly enhanced the mortality of adult R. dominica. The results of real warehouse experiments showed that S-methoprene of form II had a strong lethal effect on common grain storage pests, after 30 days of application, the corrected mortality of R. dominica was 98.33%, the corrected mortality of Tribolium castaneum（Herbst） was 99.33%, and the corrected mortality of Sitophilus zeamais (Motchulsky） and Cryptolestes pusillus（Sch?nherr） were 100%. In conclusion, S-methoprene is effective against R. dominica, and can also provide significant control of common grain storage pests when applied in the warehouse. |
