Abstract
The broad mite Polyphagotarsonemus latus (Banks) was studied for one season (2009/2010) on three pepper cultivars (Travita, Top star and Habeba) in the nethouses in Egypt. The tarsonemid mite was fed upon by the predatory phytoseiid mite Amblyseius swirskii (Athias–Henriot). Population abundance of the tarsonemid pepper prey was affected by climatic conditions and predation. A control measure of one preventive treatment in nursery and two successive curative treatments, applied mid-September, in nethouses seemed to be the most successful management of the harmful mite. The effect of constant different temperatures on P. latus development, reproduction and population growth was investigated. At 11 °C, all activity ceased and by 36 °C the adult began to slow down. Life table parameters varied greatly, especially at 21 °C and 75% R.H.
