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。
The composition of mite subfamily on citrus fruit, litchi, longan, mango, banana, rose apple and carambola in Nanning was investigated. The dominant species of predatory mite and its coincidence degree with pest mite were investigated. The adaptability and harm to environment The control of mites was analyzed. The diversity and stability of mites subfamilies of various fruit trees were analyzed. The dominant species were identified as Helicoverpa armigera and Aconitum mongolicus, followed by the serogroups A. mites and S. niger mites. These predatory mites have the strongest natural control of the harmful mites on mango trees and have the least amount of autonomic regulation on citrus trees.
