2010-2011年在广东省肇庆市对不同防治措施的柑橘园内植绥螨进行了调查,结果显示:在不使用任何农药处理的柑橘园内植绥螨有4属10种,优势种是江原钝绥螨Amblyseius eharai和海南钝绥螨A.hainanensis,分别占总数的51.3%和26.9%;在以苦参碱防治为主的柑橘园内植绥螨有1属2种,优势种是海南钝绥螨A.hainanensis,占总数的83.3%;以矿物油乳剂防治为主的柑橘园内植绥螨有2属4种,优势种是钝毛钝绥螨A.obtuserellus,占总数的69.2%;以阿维菌素防治为主的柑橘园内植绥螨仅有1属1种,为江原钝绥螨A.eharai。不同防治措施对柑橘园内植绥螨造成不同的影响,并可能导致产生不同的类群结构,进一步对不同种类植绥螨控制柑橘害虫害螨的能力进行评估,筛选出主要种类,并采取相应措施进行保护和增殖,可提高其控害效果。
In 2010-2011, the phytoseiosis mites in citrus orchards with different control measures were investigated in Zhaoqing City, Guangdong Province. The results showed that there were 4 genera and 10 species of citrus in citrus orchard without pesticide treatment. The dominant species were Jiang Yuan Amblyseius eharai and A. hainanensis accounted for 51.3% and 26.9% of the total, respectively. There were 1 genera and 2 species of phyitoriids in citrus orchards with matrine control. The dominant species was Hainan blunt A. hainanensis accounted for 83.3% of the total. There were 2 genera and 4 species of citrus orchard in the control of mineral oil emulsion. The dominant species was A.obtuserellus, accounting for 69.2% of the total. There are only 1 species and 1 species of phytoseiidae in citrus orchards, which are mainly avermectin control. They are A.eharai. Different control measures have different effects on phytoseiosis in citrus orchard and may lead to different taxonomic structures. The ability of different species of phytoseiidae to control citrus pests and mites may be evaluated, the main species screened out and corresponding measures taken To protect and multiply, it can enhance its control effect.
