Development of root knot nematode and morphometrics of females of the nematode Meloidogine incognita, as influenced by different cucurbits

Different Cucurbits were inoculated with single egg mass population of Meloidogyne incognita in order to determine the extent of morphometric and allometric variation caused by rearing on different hosts. Smaller females were produced On Momordica charanita, a relatively tolerant plant to nematode attack whereas large females were produced on highly susceptiple cucurbits like Benincasa hispida and Cucurbita moschata thereby indicating that size of females is somewhat correlated with the degree of susceptibility of the host plant.
