The cause of parathion and propoxur resistance inTyphlodromus pyri was studied in a Dutch strain in which resistance was dependent on a semi-dominant gene. Activity of glutathione S-transferase and acetylcholinesterase and reaction rate of acetylchol

Cross-resistance to diflubenzuron was found in a large number of resistant strains of the housefly. The resistant strains were found to be three to ten times less sensitive than a susceptible strain when bred in medium containing the toxicant. Select

As a basis for future investigations on the development and the nature of resistance against insecticides, the regression lines for the toxicity of γ-hexachlorocyclohexane to D. melanogaster were estimated by means of1. A contact method, in which th

The susceptibility of one susceptible and six resistant strains of houseflies to 13 organo-phosphorus compounds was measured with a contact method. Five of the strains bad been selected, both in the field and in the laboratory, with diazinon, parathi

Esterase activities were measured in homogenates of organophosphate resistant and susceptible houseflies using several substrates. No differences were found between the Cholinesterase activities. The ali-esterase activity, however, proved to be very

A simple method is described enabling the estimation of low enzymatic activities of DDT-dehydrochlorinase. Acetone powders of the insect material are incubated with DDT-suspensions obtained by adding small amounts of DDT solutions in dimethylsulfoxid

Two wild strains of Drosophila and one laboratory strain were selected for resistance to γBHC by a contact method. From each of these three strains equally resistant strains developed in about the same time. They did not become more resistant after

A factor for dieldrin resistance in a γ-BHC selected strain of Uruguayan origin was located in linkage group 4 (Hiroyoshi's numbering system) and showed approximately 40% crossover to the marker ct in F1 females. Resistance to γ-BHC is partly due t

The relation between low ***all-esterase activity and organophosphate resistance was studied in a malathion and a diazinon resistant strain of houseflies by a system of repeated back-crosses with a susceptible strain. In the malathion resistant strai
