Abstract

In field trials conducted at Guelph, Ont., methoprene (Altosid® SR-10) at 0.028 kg AI/ha (0.025 lb AI/ac) effectively controlled spring Aedes species following treatment of third- and fourth-instar larvae. However, when treated in the first to third instar, only partial control was obtained. The formulation remained active in the pools for 13 days during which time the average temperature was < 20°C. Methoprene also effectively controlled early-summer Aedes vexans (Meigen) after treatment of fourth-instar larvae. Diflubenzuron (Dimilin® 25% WP) at 0.022 kg AI/ha and 0.045 kg AI/ha (0.02 and 0.04 lb AI/ac) was effective against spring Aedes species following treatment of third-instar larvae.
