Investigations on mulberry parasitic nematodes in Guangxi
摘要
Abstract
[Objective]Plant nemalodes were identified and surveyed in some mulberry growing areas in Cuangxi in order to study their morphological characteristics, occurrence and distribution. [Method]The roots and rhizospheric soils in mulberry field of Yizhou, Xiangzhou and Hengxian of Cuangxi were collected to identify the morphological characteristics of nematodes using light microscope. [Result]Four species of plant parasitic nematodes were identified which belonged to nine genera, viz.,Meloidogyne incognita, Helicotylenchus exallus,Criconemella informis,Paratylenchus sp.,Psilenchus hi-larulus,Filenchus sp.,Tylenchorhynchus sp., Aphelenchus sp.,Gracilacus sp. Out of them, Meloidogyne incognita was highly dominated one (123 heads of 2nd instar larva per 100 Ml soil). [Conclusion]The Meloidogyne incognita was found as most dominant species in mulberry growing areas of Guangxi. It has been suggested that more attentions should be paid on controlling Meloidogyne incognita in order to enhance the mulberry productivity.关键词
