The breakdown of proattractants is predominantly due to microbial activity. Of the eight bacteria isolated from buffalo urine three have demonstrated varying ability to give rise to free phenols the formation of which was monitored by observing the build-up of 4-cresol by means of gas chromatography. These observations may provide a useful biotechnological model for controlled release of these semiochemicals in the field.enGlossina pallidipestsetseurinephenols4-cresol3-n-propylphenolkairomonesglucuronidessulphatespro-attractantscontrolled-releaseAerococcus viridansArticle
