南宁主要果树螨类亚群落结构与功能分析

SUBCOMMUNITIES STRUCTURE AND ITS FUNCTION ANALYSIS OF SPIDER MITE IN MAIN FRUIT TREES IN NANNIN

调查了南宁市柑桔、荔枝、龙眼、芒果、香蕉、蒲桃、杨桃等果树上螨类亚群落的组成,捕食螨优势类及其与害螨的吻合度、对环境的适应性和对害螨的控制力;分析各种果树螨类亚群落的多样性和稳定性,初步确定细毛神蕊螨和江原钝绥螨为有效的优势种,其次是锯齿盲走螨和尼氏真绥螨。这些捕食螨在芒果树上对害螨的自然控制能力最强,而在柑桔树上的自动调节功能最小。

This paper primarily reports the compositions of sub-communities on Citrus reliculata, Litchi chinensis, Euphoria longan, Mangifera indica, Musa cavendishii, Syzygium jambos and Averrhoa Carambola in Nanning, Guangxi. According to the functional analysis, Agist-emus terminalis,Amblyseius eharai and Typhlodromus serrulatus, Euseius nicholsi are efficient predominants. They had mostly powerful natural control ability to injurious mites in mango tree but less capable in citrus tree.
