ABSTRACT
Two residual insecticides (Icon 10% WP, ICI and Ficam W 80% WP, CAMCO) were in 1989 tested in field trials in Tajikistan, Azerbaijan and Uzbekistan against Anopheles superpictus, An. sacharovi, An. pulcherrimus, An. martinius, Culex pipiens, Aedes caspius, and Ae. vexans. In dosages recommended by the producing companies (0.025 g/m2 a. i. for Icon and 0.4 g/m2 for Ficam), the above preparations showed residual action during 2-3 months. Icon and Ficam did not cause irritability and repellency in mosquito, which did not migrate to unsprayed rooms of cattle sheds. In areas where the experimental trials were large-scale, a stable decrease in mosquito density was achieved. An insecticide action of ICON was also noted on house flies, cockroaches, bed bugs, fleas and spiders.
