Nematode reproduction in environments of fluctuating aeration

Reproduction of Aphelenchus avenae, reared on Rhizoctonia solani growing on steamed wheat seeds and Caenorhabditis sp., reared on a mixed bacterial culture grown on oatmeal, was significantly reduced at 5% oxygen and inhibited at 4% oxygen and below. Aeration ranging from atmospheric air (21%) to 10...

Description
Résumé:Reproduction of Aphelenchus avenae, reared on Rhizoctonia solani growing on steamed wheat seeds and Caenorhabditis sp., reared on a mixed bacterial culture grown on oatmeal, was significantly reduced at 5% oxygen and inhibited at 4% oxygen and below. Aeration ranging from atmospheric air (21%) to 10% oxygen had no effect on reproduction. Close interval (5 days or less) fluctuations, between high and low oxygen concentrations, inhibited population buildup of Hemicycliophora arenaria on tomato in soil, and of A. avenae and Caenorhabditis sp. in vitro. In soil tests with H. arenaria exposed to 12 hr of nitrogen every three days (in air) inhibited the rate of buildup compared to controls maintained in continuous air. With the in vitro studies, as little as 4 hr nitrogen every 3 days (stored in air) significantly influenced the population numbers
