Meloidogyne javanica Parasitic on Peanut.
Peanut fields in four governorates of Egypt were surveyed to identify species of Meloidogyne present. Fourteen populations obtained from peanut roots were all identified as M. javanica based on perineal patterns, stylet and body lengths of second-stage juveniles, esterase phenotypes, and restriction fragment length polymorphisms of mtDNA. Three of 14 populations, all from contiguous fields in t...
متن کاملInteraction of Meloidogyne javanica with Different Races of Meloidogyne incognita.
The interspecific interactions of Meloidogyne javanica with races 1, 2, 3, and 4 of M. incognita on tomato were determined. Impacts of the interactions on fecundity and morphometrics of females were also examined. Mutually inhibitory interactions occurred between M. javanica and the races of M. incognita, but the negative interactions did not reflect in plant growth. Numbers of root galls, egg ...
متن کاملMeloidogyne javanica on Peanut in Florida.
A mixed population of Meloidogyne arenaria race 1 and M. javanica race 3 is reported on peanut from a field in Levy County, Florida. Confirmation of M. javanica on peanut is based on esterase and malate dehydrogenase isozyme patterns resolved on polyacrylamide slab gels following electrophoresis, and perineal patterns. Up to 29% of 290 individual females collected from peanut roots in the field...
متن کاملReaction of citrus rootstocks to Meloidogyne javanica.
The response of Citrus spp. and related rootstocks to a population of Meloidogyne javanica was evaluated in a screenhouse experiment. Palestine and Rangpur lime, rough lemon, sour orange, Sexton and Thentriton tangelo, and Volkamer lemon were not infected by M. javanica. Galls and tip swellings were observed on the roots of Poncirus triloliata and Troyer citrange. There was no evidence of nemat...
متن کاملLectin Binding to Meloidogyne javanica Eggs.
T h e egg shell is one of the most impor tant and least understood of the nematode's protective membranes. The egg shell of Meloidogyne incognita consists mostly of proteins (50%), chitin (30%), and traces of lipids and unidentified materials (1). In the present work we used fluorescein isothiocyanate (FITC)-labeled lectins (2) to identify the carbohydrate residues on the gelatinous matr ix and...
