Larvae of Anopheles albimanus Wiedemann were collected from representative breeding sites from July 18, 1976, to March 25, 1978 in conjunction with a sterile insect release program on the Pacific coast of El Salvador, Central America, The number of larvae collected per 100 dips from breeding sites was compared with the number of adults captured per man-hour at specified cattle stables throughout the area during the same period. It was found that the larval surveys were not an accurate indicator of the actual population during the rainy season. The study shows a need for a more reliable system of sampling An. albimanus larvae in wet season flooded areas if larval collections are used to show relative abundance of that species.
