Abstract

The effect of treatment with pesticides (sanmite) and four plant extracts on
the biology of spider mite and citrus brown mite was investigated. Treatment with the
pesticides decreased female longevity, preoviposition and oviposition period, number
of eggs and percentage of hatchability in both Tetranychid mites; Tetranychus urticae
Koch and Eutetranychus orientalis (klein).
Treatment with plant extracts; worm wood, caraway. lupin and lantana,
decreased female adult longevity, oviposition period, egg hatchability and number of
deposited eggs in both mite species.
