Abstract

This  work  was conducted  to  determine  the  effect  of temperature  and prey  type  on the  biology  of Typhlodrompis  enab El-Badry  (Acari: phytosiidae). This  phytoseiid  was reared  on  three  tetranychids,  (i. e. Eutetranychus  orientalis  (Klein), Tetranychus  urticae  Koch  and Panonychus ulmi  (Koch))  at 20,25,30°C  and 65±5% RH.  All life cycle parameters decreased as temperature increased.  Obtained relative  values  for  males  were generally  less  than  those  of  females. E. orientalis was the preferred one followed by T. urticae  and  the  least  was P. ulmi.
