Abstract


Interaction of soil predacious mites and citrus nematodes (parasitic and saprophytic), in citrus orchard under different regime of fertilizers; Effect on the population densities and citrus yield. During a course of study on the predacious mites and their relationships with citrus nematodes, there were several population interactions, greatly varied according to the regime of fertilizers. In general the presence of organic manure encourage the population of predacious mites to increase, although decreasing the portion of organic manure discourage the populations. There were several positive interactions between both populations and that of predacious mites over exploited the nematode populations in several cases. Yield was almost the same under the different combinations, although the quality as measured by fruit size, weight/fruit, diameter/fruit and total solible solids was better under organic manure regime.
