摘要
根据3年调查资料鉴定,在广西柑桔园中有25种捕食螨,其中以植绥螨占优势。采用“模糊综合评判法”,结果表明,冲绳钝绥螨、尼氏真绥螨、真桑钝绥螨和江原钝绥螨为优势种,其对害螨控制能力依次为:江原钝绥螨、真桑钝绥螨、冲绳钝绥螨、尼氏真绥螨。系统调查发现,藿香蓟上植绥螨的种类与柑桔上最为相似,其次是小飞蓬,这提示了柑桔园中保留或种植藿香蓟等良性杂草,保护利用捕食螨防治桔全爪螨的可能性。3年来已在生产实践中获得良好的效果。
25 species of predacious mites,in which the Amblyseius spp.ofPhytoseiidae were predominant,found in citrus orchard in GuangxiZhuang Autonomous Region were reported.Based on the result of fuzzysynthetic analysis,the control capability sequence of dominant speciesagainst citrus red mite Panonychus citri were determined as Amblyseiuseharai>A. makuwa>A. okinawanus>Euseius nicholsi. The systematic investigations showed that the phytoseiid mite spe-cies occurred on Ageratum conyzoides were most similar to those on cit-rus tree.It was suggested that to protect and utilize the predaciousmites by retaining or growing the good grasses such as Ageratum cony-zoides,etc.,in citrus orchard for controlling citrus red mite is available.Favourable results of those implementations were obtained through thepast three years.
