Insecticide Resistance In House Flies Research Articles

An analysis of house fly resistance to insecticides in California.

The pattern of insecticide resistance in house flies, Musca domestica L., from 6 areas of California was found to reflect the differing chemical-control practices in each area. DDT resistance continues to be high in all areas despite more than 10 years of nonuse of this compound for fly control. It shows positive correlation with diazinon resistance but not with malathion resistance, and thus its prolonged stability was likely enhanced by diazinon pressure. Dieldrin resistance also remains high, but shows no correlation with organophosphorus resistance. The non-identity of diazinon and malathion resistances was clearly discernible. High resistance to diazinon (20.7×) in the Anaheim strain was accompanied by only moderate resistance to malathion, and high resistance to malathion in the Moorpark strain was accompanied by only moderate resistance to diazinon (7.1×). The highest degree of resislance observed (at the LD90 level) by topical application of organophosphates and carbamates was: malathion >60×, diazinon 25×, ronnel 14×, fenthion 10.1×, dimethoate 4.2×, dimetilan 3.7× and Hercules 8717-E [ m -(2-propynyloxy) phenyl methylcarbamate] 3.5×.

A Study of Insecticide Resistance in House Flies of Germany and France1

Strains of the house fly (Musca domestica L.) from nine areas of Germany and France were laboratory tested to determine their susceptibility to DDT, lindane, dieldrin and malathion by topical application in acetone solutions. All strains were derived from flies which were collected in the field and reared in the laboratory until several successive generations had been tested. All strains tested were found to be significantly resistant to DDT, a Heidelberg strain having an LD-50 (lethal dose required for 50% mortality) of 71 times, La Rochelle 44 times, Orleans 36.7 times, and Munich 29.7 times as great as a non-resistant laboratory strain cited. Similarly five strains showed a moderate degree of resistance to lindane and five to dieldrin. None were shown to be significantly resistant to malathion.
