Inhibition of Acetylcholinesterases from Aphelenchus avenae by Carbofuran and Fenamiphos.
Exposure to carbofuran and fenamiphos for 72 hours reduced the numbers of active Aphelenchus avenae in aqueous suspension by > 75%. When nematicides were removed, many A. avenae exposed to carbofuran resumed normal movement but A. avenae treated with fenamiphos did not recover. Acetylcholinesterase (AChE) activity was suppressed by > 95% in nematodes treated with carbofuran or fenamiphos. Howev...
متن کاملAge specific sensitivity of the nematode Aphelenchus avenae to mercury toxicity.
Although one of the ultimate goals of ecotoxicology is to predict the effects of chemical substances and compounds on whole communities and ecosystems, it is generally accepted by ecotoxicologists that single-species toxicity tests may provide an adequate first step toward the ecological risk assessment of pollutants in soil and water. Consequently, several toxicity tests (ASTM 1993) have been ...
متن کاملGametogenesis in amphimictic and parthenogenetic populations of Aphelenchus avenae.
The female reproductive system of Aphelenchus avenae, studied in orcein-stained material, showed a peculiar structural pattern not yet reported in other nematodes. Chromosome morphology and behavior during gametogenesis could be studied in more detail than in other tylenchid or aphelenchid species investigated to date. In a bisexual population from Australia, gametogenesis was by normal meiosis...

15 صفحه اولRespiration Responses of a Caenorhabditis sp. and Aphelenchus avenae to the Nematicide, 1,2-dibromoethane (EDB).
The respiration rate of third stage larvae of Caenorhabditis sp. exposed to 0.53 x 10(2) M EDB was 120% greater than in untreated checks and was highest shortly after the exposure began. Similarly-treated third- and fourth-stage Aphelenchus avenae exhibited no marked respiratory response. Different responses of these animals to EDB probably reflect basic physiological differences between the ne...
