摘要:

化学类谷物保护剂的不合理使用会使害虫产生抗药性,同时对人类饮食健康有着严重的威胁。因此,如何科学合理地使用化学类谷物保护剂已成为保护粮食安全亟需解决的问题杂拟谷盗是为害粮食作物的主要储粮害虫,本试验选用了化学类谷物保护剂与生防菌相结合的方式,采用混毒法测定甲基嘧啶磷和球孢白僵菌对杂拟谷盗的联合毒力效果。结果表明,在甲基嘧啶磷熏蒸处理中,添加球孢白僵菌后对杂拟谷盗的灭杀作用要好于单独使用甲基嘧啶磷的处理效果。同样地,加入甲基嘧啶磷的球孢白僵菌处理对于杂拟谷盗的灭杀效果也大于单独使用球孢白僵菌的处理效果。结果表明,甲基嘧啶磷和球孢白僵菌的联合使用能够显著提高害虫的死亡率,并且对化学类谷物保护剂与生防菌联合使用具有实践指导意义。

Abstract:

The unreasonable use of chemical grain protectants has made the insect resistant and poses a serious threat to human dietary health. Therefore, how to scientifically and reasonably use insecticides has become an urgent problem to protect food security. Tribolium confusum is the main stored grain pests that harm food crops. In this experiment, a combination of chemical grain protectant and biocontrol bacteria was used to determine the co-toxicity effect of pirimiphos-methyl and Beauveria bassiana against Tribolium confusum. The results showed that in the fumigation treatment with pirimiphos-methyl, the combined treatment with the addition of Beauveria bassiana improved the killing effect of pirimiphos-methyl on Tribolium confusum compared with the treatment of pirimiphos-methyl alone. Similarly, in the treatment of pirimiphos-methyl,the killing effect after adding Beauveria bassiana was better than that of the treatment using Beauveria bassiana alone. Overall, this study showed that the synergistic effect of pirimiphos-methyl and Beauveria bassiana was able to significantly increase the mortality of pests and had practical guidance for the combination of chemical grain protectant with biobacteria.

Key words: Tribolium confusum, chemical grain protectants, biocontrol bacteria, indoor toxicity, synergistic effect
