The white peach scale (WPS), Pseudaulacaspis pentagona (Targioni-Tozzetti) (Homoptera: Diaspididae), is a worldwide polyphagous scale insect. It is widely distributed in Turkey, where it is the main pest of peach trees. The development and fecundity of P. pentagona were examined at different temperatures and on different hosts in the laboratory; from these data, life tables were constructed and intrinsic rates of increase were calculated. The longevity of WPS decreased with a rise in temperature. At 25 degrees C the largest number of crawlers (76.1 crawlers/female) was observed. The development time of WPS was generally longer on peach than on squash or potato; fecundity was higher on potato than on the other hosts, potato tubers and peach trees.
