Behavior of Tethered Meloidogyne incognita.
The tethered-nematode technique was adapted for use with second-stage juveniles of Meloidogyne incognita. The data demonstrate that M. incognita exhibits the same patterns of behavior as adults of the free-living nematode, Caenorhabditis elegans. The principal differences are that M. incognita is slower and less regular in its behavior than C. elegans. The frequency of normal waves is about 0.2...
متن کاملSurface Coat of Meloidogyne incognita.
The nematode surface coat is defined as an extracuticular component on the outermost layer of the nematode body wall, visualized only by electron microscopy. Surface coat proteins of Meloidogyne incognita race 3 infective juveniles were characterized by electrophoresis and Western blotting of extracts from radioiodine and biotin-labeled nematodes. Extraction of labeled nematodes with cetyltrime...
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 کاملA Method for Generating Meloidogyne incognita Males.
A method for producing mass quantities of Meloidogyne incognita males free from other developmental stages was developed. Host plants were grown hydroponically to facilitate nematode harvest. Pruning stress was shown to cause a higher percentage of juveniles to develop as males vs. a no-stress control. Application of pruning stress in the first 48 hr post-inoculation was also shown to be more e...
متن کاملPredicting Damage of Meloidogyne incognita on Watermelon.
Quantitative growth response of watermelon (Citrullus lanatus) sensitive to Meloidogyne incognita is poorly understood. Determination of soil population densities of second-stage juveniles (J2) of M. incognita with Baermann funnel extraction often is inaccurate at low soil temperatures. In greenhouse experiments, three sandy soils were inoculated with dilution series of population densities of ...
