Modelling 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...
متن کاملEffects of Fluctuating Temperatures and Different Host Plants on Development of Pasteuria penetrans in Meloidogyne javanica.
Greenhouse and growth room experiments were conducted to investigate the effect of host plant in relation to different nematode inoculum levels, and temperature fluctuations on the development of Pasteuria penetrans. Host plant affected the development of P. penetrans indirectly through its effect on nematode development. Endospores collected from Meloidogyne javanica females reared on differen...
متن کاملSpecific Gravity of Spores of Pasteuria penetrans and Extraction of Spore-filled Nematodes from Soil.
The specific gravity of spores of Pasteuria penetrans collected from Meloidogyne arenaria was found to be around 1.28. Increasing the sucrose concentration used for the extraction of Pratylenchus scribneri from a specific gravity of 1.14 to 1.26 led to the recovery of higher numbers of specimens filled with spores of Pasteuria sp. (P </= 0.05). The numbers of spore-filled specimens of Hoplolaim...
متن کاملBiological Control of Meloidogyne incognita by Paecilomyces lilacinus and Pasteuria penetrans.
The root-knot nematode Meloidogyne incognita was controlled more effectively and yields of host plants were greater when Paecilomyces lilacinus and Pasteuria penetrans were applied together in field microplots than when either was applied alone. Yields of winter vetch from microplots inoculated with the nematode and with both organisms were not statistically different from yields from uninocula...
متن کاملSuppression of Meloidogyne incognita and M. javanica by Pasteuria penetrans in Field Soil.
The role of Pasteuria penetrans in suppressing numbers of root-knot nematodes was investigated in a 7-year monocuhure of tobacco in a field naturally infested with a mixed population of Meloidogyne incognita race 1 and M. javanica. The suppressiveness of the soil was tested using four treatments: autoclaving (AC), microwaving (MW), air drying (DR), and untreated. The treated soil bioassays cons...
