Infestazioni di Meloidogyne incognita e M. arenaria su Salix alba

Abstract

This report refers to a single female of Pratylenchus brachyurus (Godfrey) Filipjev et Schuurmans Stekhoven recovered from the roots of rice, Oryza sativa L., collected from Ipora, Pr., Brazil, in which intra-uterine development of eggs was observed. Seven eggs were noted within the uterus, 3 eggs contained fully developed larvae and 4 eggs appeared undifferentiated. The uterus was greatly enlarged and the ovary displaced anteriorly, terminating in the region of the dorsal gland orifice. No free larvae were observed inside the body cavity. Unfortunately, the specimen had been placed in 5% formalin prior to examination and therefore subsequent development could not be observed.
