Chilocorus bipustulatus L. is one of important natural enemies of scale insect (Diaspididae) in fruit orchard. Investigation on rearing methods of this natural enemy would improve development of biocontrol programmes. Determining biological factors and suitable hosts could be the most important stage in any biological control program. In the present study, three different hosts including Pseudaulacaspis pentagona Targioni, Chrysomphalus dictyospermi Morgan and Sitotroga cerealella Olivier in different beds of food substrates, including pumpkin, potato and mulberry branches were tested and compared their efficiency in C. bipustulatus rearing. Larval, pupal and adult stage period in different treatment estimates and were compared statistically. These results showed that growing mulberry scale insect on pumpkin and potato, were more appropriate and complete life cycle on C. bipustulatus rearing. In this assessment biological characteristics including duration of egg incubation, larval, pupal, and adult stage of C. bipustulatus when P. pentagona considered as a prey, were 9.2 ± 2.3, 25.8 ± 2.7, 8.6 ± 2.1 and 33.4 ± 6.1 days respectively.
