A novel method for assessing the effect of photoperiod and temperature on reproductive biology of the predators Hippodamia variegata (Coleoptera: Coccinellidae) and Micromus tasmaniae (Neuroptera: Hemerobiidae)

A novel experimental approach for the simultaneous investigation of the effects of photoperiod and temperature showed evidence of diapause in Hippodamia variegata Goeze but not in Micromus tasmaniae Walker. Results are discussed in relation to their potential as greenhouse biocontrol agents.
