Abstract

The current study indicated that the type of tested nematode food and temperatures had slightly significantly difference on the incubation period of uropodid mite, Uroobovilla krantzi (both sexes) when fed on free living and parasitic nematodes. The longest incubation period durated 4.1 days when females fed on free nematodes at 15 ºC, but the lowest one was 1.6 days at 35 ºC when males fed on parasitic nematodes.Whoever, the data indicated that the tested nematodes significantly affected on the mite life cycle.Also the study denoted that the type of food had very highly significant differences effects on male and female longevity. Eggs of mites were apparently produced only by fertilized females. Significantly more eggs were laid when mites fed on free nematodes at 35 ºC. (132.2 eggs), but the lower eggs were observed when females fed on parasitic nematodea at 15 ºC
