Tests with single injections of methoxychlor black fly (Diptera: Simuliidae) larvicides in large rivers



Tests with single injections of methoxychlor black fly (Diptera: Simuliidae) larvicides in large rivers



Canadian Entomologist 106(3): 285-305



In tests in 1969-71, single applications of 0.18-0.24 p.p.m. methoxy-DDT (methoxychlor) as an emulsifiable concentrate poured over a period of 15 min into the Saskatchewan River in Canada removed 75-99% of larvae of Simulium arcticum Mall. from sections of the river 23-34 km long. Higher concentrations (0.30-0.31 p.p.m.) eliminated about 98% of the larvae from rapids 64 km distant and an estimated 46% at a distance of 139 km.
