Resistance of Anhydrobiotic Aphelenchus avenae to Methyl Bromide Fumigation.
The effect of methyl bromide (MB) was tested on active and anhydrobiotic Aphelenchus avenae. A. avenae was induced into anhydrobiosis by three different techniques. Both active and anhydrobiotic nematodes were subjected to 3,000 mu1 MB/liter air for 14 periods from 0 to 82 h. Anhydrobiotic nematodes were more resistant to fumigation than active nematodes, regardless of the technique used to induce anhydrobiosis. The percent survival decreased with increasing MB exposures (mu1 MB x h). For an LD of 45,000-54,000 mu1/1 x h were required for active nematodes and >279,000 mu1/1 x h for anhydrobiotic nematodes.
