    Abstract

    Glasshouses have a favourable climate for greenhouse red spider mite, which can rapidly proliferate. Up to 1959 its practical control has been by chemicals only. Bravenboer studied whether biological control was also possible.
    Chemical treatment acted as a density-independent factor and was unable to regulate the population. It must frequently be repeated and would certainly lead eventually to resistance of the mite, so causing a failure of chemical control in the future.

    The predators Stethorus punctillum and Typhlodromus longipilus could act as density-dependent factors and regulate the population of Tetranychus urticae. Although the conditions for biological control were favourable in greenhouses, the predators alone were seldom able to give economic control of T.urticae. A single application of a selective acaricide per year gave adequate control.

    The first chapters deal also with taxonomic problems over Tetranychus urticae, with the influence of temperature on the development of both T. urticae and its mentioned predators, their egg production, their diapause (not for Typhlodromus longipilus), the influence of the host plant on the reproduction of T. urticae and many observations on the behaviour of predators in the presence of their prey.
