SUMMARY The biological control of red spider mite using the predatory mite Phytoseiulus persimilis was investigated in 1971, 1972 and 1974. Experiments in small glasshouse compartments showed that the predator should be introduced when the leaf damag

SUMMARY During 1969/74 different methods of using the parasite Encarsia formosa to control whitefly infestations on tomatoes in glasshouses have been evaluated commercially. The most effective control was achieved by the Glasshouse Crops Research Ins

Trials with the parasiteEncarsia formosa to control whitefly (Trialeurodes vaporariorumWestw.) on cucumbers showed that the most predictable results were obtained by the “classical” method of establishing a low, even infestation of the pest on th

Cross breeding experiments with British and North American colour forms of the mites included in the Tetranychus telarius complex suggest that T. urticae Koch is the correct name for the green form, and T. cinnabarinus Boisd. for the reddish form. Di

Under glass Tetranychus urticae Koch spreads by (a) migration of teneral females to ovi-position sites (b) migration of mites from heavily infested plants by falling without the usual silken parachutes normally used by Tetranychid mites and (c) movem

There are two forms of greenhouse red spider mite in Great Britain, one with green summer females and the other with reddish brown females. The latter, usually associated with carnations, does not hibernate. Breeding experiments show that these forms

The interaction between Tetranychus urticae and Phytoseiulus riegeli on cucumbers was studied in several different experiments at two centres. It was shown that if the predator is introduced at a low prey population, elimination of the mites occurred
