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

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

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

Samples of spider mite populations collected from ten rose houses were tested for resistance to parathion, tetradifon and dicofol. Despite the fact that for a period of 7 years tetradifon and dicofol had not been used, resistance to these acaricides

Colonies of the predatory mite, Amblyseius potentillae (Garman), fed on different kinds of food responded differently to short-day photoperiods with respect to entering diapause. Photoperiodic induction of diapause was normal in predators fed on wild

An investigation was made into the possibility of establishing complete reproductive incompatibility between a laboratory strain and derived stocks of Tetranychus urticae, by the induction of chromosome mutations. The degree of hybrid sterility of si

An albino male was discovered in a population of Tetranychus pacificus, as a result of spontaneous mutation. It appeared that this albinism was recessive and under monogenic control. A maternal effect was demonstrated. The albinism is a suitable mark
