摘要:

本研究探究了不同释放次数、释放量的胡瓜钝绥螨及化学杀螨剂对梨园二斑叶螨的防治效果。结果表明,胡瓜钝绥螨对二斑叶螨的防治速效性低于化学杀螨剂,但持效期更长。释放2次胡瓜钝绥螨后30 d的防治效果优于释放1次胡瓜钝绥螨及化学杀螨剂处理;在单次释放条件下,释放量225×104 hm-2处理在释放后15、30 d的防治效果显著(p<0.05)高于释放量112.5×104 hm-2处理;分2次释放时,首次225×104 hm-2+二次112.5×104 hm-2的组合与2次均释放112.5×104 hm-2的防治效果无显著差异。本试验结果表明,将胡瓜钝绥螨分次释放结合适宜释放量,可在梨园二斑叶螨长效防控中发挥较好的效果,优于常规化学杀螨剂,具有良好的应用前景。

Abstract:

This study investigated the control efficacy of Amblyseius cucumeris and chemical acaricides with different release frequencies and dosages against Tetranychus urticae Koch in pear orchards. The results demonstrated that Amblyseius cucumeris exhibited lower immediate control efficacy compared with chemical acaricides but demonstrated superior persistence. The 30-day control efficacy after two releases of Amblyseius cucumeris was superior to that of single releases of Amblyseius cucumeris and chemical acaricides. Under single-release conditions,the treatment with 2.250 million heads per hectare showed significantly (p<0.05) higher control efficacy at 15 and 30 days post-release compared to 1.125 million heads per hectare. When released twice,the combination of the first 2.250 million heads per hectare and the second 1.125 million heads per hectare showed no significant difference in control efficacy compared to both releases of 1.125 million heads per hectare. The experimental results indicated that staged release of Amblyseius cucumeriss combined with appropriate dosages demonstrated good efficacy in long-term control against Tetranychus urticae Koch in pear orchards,outperforming conventional chemical acaricides and showing promising application prospects.
