摘要

在真菌中，拟青霉属(Paecilomyces)被认为是一种很有前途的生物防治剂，在减少根结线虫(RKN)和其他线虫种群方面具有很高的潜力。本研究研究了一种土壤菌丝马泉拟青霉及其对RKN卵的离体致病性。在温室试验中，测定了植株的根重、株长、鲜重和干重、瘿指数和病虫卵比例。马quandii通过抑制其根腐蚀发病机制和减少产卵量，有效地促进了接种了incognita的植株的生长。在25℃条件下，大量线虫卵被马quandii寄生，抑制了线虫幼虫的发育。

Pathogenicity of Paecilomyces marquandii on eggs of Meloidogyne incognita

Among fungi, species of the genus Paecilomyces are considered as promising biological control agents with high potential to reduce root-knot nematode (RKN) and other nematode populations. In this research we investigated a soil hyphomycetes, Paecilomyces marquandii and its pathogenicity on eggs of RKN in vitro. In greenhouse test, root weight, plant length, fresh weight and dry weight of plants, gall index and proportion of infected eggs were determined. P. marquandii, effectively promoted growth of plants inoculated with M. incognita by suppressing its pathogenesis as root galling and reducing egg mass production. At 25 °C, a great number of nematode eggs were parasitized by P. marquandii, inhibiting juvenile development.

期刊介绍： Journal of Crop Protection is one of the TMU Press journals that is published by the responsibility of its Editor-in-Chief and Editorial Board in the determined scopes. Journal of Crop Protection (JCP) is an international peer-reviewed research journal published quarterly for the purpose of advancing the scientific studies. It covers fundamental and applied aspects of plant pathology and entomology in agriculture and natural resources. The journal will consider submissions from all over the world, on research works not being published or submitted for publication as full paper, review article and research note elsewhere. The Papers are published in English with an extra abstract in Farsi language.
