Spider mite populations were collected from wild plants in the Aalsmeer district at varying distances from rose houses. Resistance to organophosphates and to tetradifon was found to be present in populations collected close to glasshouses. The presen

A comparative study was made on the reproduction of two predacious mites, Typhlodromus pyri and Amblyseius potentillae. A. potentillae proved to be the more prolific species of the two. It produced a mean total number of 35 eggs per female versus 19

Resistance to dicofol in a Russian and a Dutch population of Tetranychus urticae was analyzed genetically. In both cases the resistance was due to the operation of a single, nearly recessive gene. A test for allelism revealed that both genes reside a

Partial reproductive incompatibility is usually found between populations of Tetranychus urticae of different origin. It was found that the induction of chromosome mutations in a population increases the degree of reproductive incompatibility towards

The induction of chromosome mutations with regard to genetic control may affect the mating competitiveness of spider mite males. It appeared from competition experiments that the mating competitiveness of males from chromosome mutation strains was on

Cold-hardiness was studied in the predatory miteAmblyseius potentillae (Garman) by determining the mortality after exposure to −5°C. Predators reared under diapause-inducing conditions were more cold-resistant than mites that had been kept under l

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
