Life table of Tetranychus urticae and Phytoseiulus persimilis on bean leaflets were studied under laboratory conditions in three seasons. For T. urticae the development time from egg to adult varied from 7 to 24 days and the highest immature mortality was 78.70 % in winter. Eggs laid by females were 88.1 eggs in autumn and 70.6 eggs in summer season. The gross reproductive rate (GRR) was the hi...

Climate change models predict that the frequency, intensity and duration of heat waves will increase in next decades. Heat can have profound impact on reproduction biocontrol agents ranging from postponing oviposition to manipulating offspring quantity via egg number quality size. Such species-specific responses stress may also affect their success controlling target pest. Here, we evaluated pr...
