RESUMO
Exposure of spring Aedes larvae to Altosid Liquid Larvicide formulated on the granular carrier Biodac under field conditions was evaluated. Both aerial and hand-applied treatments were monitored. Mosquitoes collected from aerially treated sites (9 kg/ha) showed an average 80% mortality. In hand-treated sites excellent control was achieved at label rates of 11.3-14.7 kg/ha (10-13 lb/acre); at dosages less than recommended rates, control was unsatisfactory.

Larvae of Culex pipiens and Cx. restuans in catch basins were exposed to Altosid pellets (4% active ingredient, [S]-methoprene) applied at a rate of 11.3 kg/ha (7 g of pellets per catch basin). Under field conditions, the pellets yielded an average 82% emergence inhibition of adult mosquitoes over the 15-wk trial period.
