Life-histories and habits of the clover mite, Bryobia praetiosa Koch and the brown mite, B.
Morphology: Phytoseiids bear an entire dorsal plate with less than 23 pairs of setae.
The stigmata open between legs III and IV and the metasternal plates are small.
The legs are undifferentiated, usually with two claws and an empodium, and the digits of the male spermadactyls are distally free.
Life cycle: Phytoseiids, fast-moving, proactive predators, live on plants and in the upper soil layers.
Most species develop within a week at 27°C and 60-90% relative humidity and usually deposit 30-40 eggs per female. van de Vrie was with the Institute for Phytopathological Research, Wageningen, The Netherlands. Part I is a review of the pertinent literature and a discussion of the biology and ecology of various spider mite enemies, their potential as biological control agents, and the effects of pesticides on their populations.

PDF of full article, Cite this article The two papers presented here were prepared at the request of the Special Committee of the International Biological Program, as part of a broad program on the ecology and natural control of spider mites (Tetranychidae) on a worldwide basis. Sex determination in most phytoseiids is by parahaploidy (a few species are thelytokous) and the sex ratio in the field is around 0.75. Phytoseiids survive winters either by going into a facultative reproductive diapause (induced by a short daylight and low temperatures) or by being resistant to low temperatures.Phytoseiids disperse by running on leaves, walking along spider mite webs, crawling on the soil and while borne on air streams.
