Abstract

Biology of the most common phytoseiid predator Amb6iseius gos­sipi was influnenced with feeding on the citrus brown mite Eutetrany­chus onentalis treated with some acaricides. Tedifol proved to be the most effective chemical against the female predator fecundity as it in­hibited egg laying completely. Kelthane / Sumithion prolonged the dura­tion of predator development compared with the control and treatments with the other two acaricides. Hatchability percentage of eggs of the resulting generation was reduced to zero % with kelthane / Sumithion, while it reached 10% with kelthane and more than 90% in the control.
