Abstract : Population dynamics and control studies on Culicoides sand flies were continued at Parris Island, SC, and Yankeetown, FL. Adult seasonal patterns were monitored by NJ light traps. Five species, C. barbosai Wirth and Blanton, C. furens (Poey), C. hollensis Melander and Brues, C. melleus (Coquillett), and C. mississippiensis Hoffman are considered abundant. C. barbosai, C. furens and C. melleus are present from mid-April through late October; C. hollensis and C. mississippiensis peak in the spring and fall of the year. A comparison of several population survey techniques indicated that CDC-type traps baited with CO2 gas and used in conjunction with New Jersey traps should give a reliable estimate of Culicoides activity during chemical control tests. Twenty-one different larval habitats were identified at Parris Island. These data suggest that a properly timed effective larvicide could reduce adult emergence by 53% by treating 30% of the marsh. In chemical control studies, laboratory treated screens, field ground ULV and aerial ULV tests were conducted. NRDC-161 and permethrin gave ca. 100% mortality 168 days after the screens were treated at .125% A.I. (wt/vol. technical in acetone) for NRDC-161 and at .5% for permethrin. Deet-treated net jackets were tested in Panama and provided ca. 90% protection.
