The release of about 4.3 million chemosterilised males of Anopheles albimanus Wied. at Lake Apastepeque in El Salvador (cf. preceding two abstracts) over a 5-month period in 1972 resulted in a 99% reduction in the level of the indigenous population of this species from both larval and adult counts. The maximum reduction (95-100% in various collections) occurred in September and October, when the natural population normally reaches its highest level.
