Attachment of Pasteuria penetrans Endospores to the Surface of Meloidogyne javanica Second-stage Juveniles.
Pasteuria penetrans spore adhesion to Meloidogyne javanica second-stage juveniles (J2) was examined following several different pretreatments of the latter. The detergents sodium dodecyl sulfate and Triton X-100, the carbohydrates fucose and alpha-methyl-D-mannoside, and the lectins concanavalin A and wheat germ agglutinin reduced spore attachment. Spores exposed to M. javanica surface coat (SC...
متن کاملEstimating Incidence of Attachment of Pasteuria penetrans Endospores to Meloidogyne spp. with Tally Thresholds.
Pasteuria penetrans has .been identified as an important biological control agent of root-knot nematodes. In this study the use of tally thresholds was evaluated for estimating P. penetrans endospore attachment to second-stage juveniles (J2) of Meloidogyne spp. A tally threshold (T) is defined as the maximum number of individuals in a sample unit that may be treated as absent based on binomial ...
متن کاملAffect of Different Ages of Second Stage Juveniles of Meloidogyne Chitwoodi on the Attachment of Pasteuria Penetrans to the Cuticle of Nematode
Pasteuria penetrans is a bacterial parasite of some plant parasite of nematodes whichcan attach to the cuticle of nematode. Differences in attachment of P. penetrans spores to the second stag juvenile (J2) cuticle may provide evidence for nematode cuticle diversity even between different ages of J2s. For investigating this purpose, we studied the effect of different ages of th...

متن کاملModelling Movements of Root-knot Nematodes Meloidogyne spp. Juveniles when Encumbered with Spores of Pasteuria penetrans
A system for monitoring movement of the free-living second stage juveniles of root-knot nematodes (Meloidogyne spp.) using digital image analysis is described. The method is based on the analysis of video sequences of movement of individual random nematodes encumbered with or without Pasteuria penetrans endospores. Software packages were used to grab video images, to process images and to monit...
