Abstract: A trap with five entry holes was used to study the attractant effect of carbon dioxide, octenol, a mixture of 4-methylphenol octenol: 3-n-propylphenol and acetone on cafches of Anopheles gambiae in the laboratory. The catches in the trap baited with carboa dioxide released from a cylinder were much better than those in the trap baited with dry ice. A mixture of 4-methylphenol: octenol: 3-n-propylphenol released at 0.39mg/h, 0.13mg/h and 0.022mg/h respectively showed little attraction to Anopheles gambiae. Octenol in paraffin oil releasedat 0.025mg/h used by itself attracted Anopheles gambiae in number similar to those with acetone released at 0.25ml/h. Acetone at 0.25ml/h and carbone dioxide acted synergistically in attracting significantly greater mumbers of Anopheles gambiae
