“…The two‐spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) is the most important pest mite worldwide for its extensive damage to several crops and numerous cases of pesticide resistance 3 . Τhe tomato red spider mite Tetranychus evansi Baker and Pritchard (Acari: Tetranychidae), and the peanut red spider mite Tetranychus ogmophallos Ferreira and Flechtmann (Acari: Tetranychidae) are emerging pests in tomato and peanut, respectively, and have caused considerable economic damage to these crops 4 – 6 .…”

“…Chemical control is the main method used for controlling populations of mites and aphids 6 – 8 . However, the efficacy of this method is not always effective, since these pests become more prone to evolving pesticide resistance due to their high biotic potential and high genetic variability 3 , 4 , 6 , 7 . Intensification of chemical sprays has led also to environmental pollution, and poisoning risks to farmers and consumers 8 , 9 .…”

The ladybird Eriopis connexa is an important natural enemy of several pest arthropods in agroecosystems. High population of this predator is frequently observed in strawberry and soybean crops associated with spider mites. We used two-sex life table parameters to evaluate under laboratory conditions, the suitability of three species of spider mites (Tetranychus evansi, Tetranychus urticae, Tetranychus ogmophallos), and a species of aphid (Myzus persicae) as a prey for the predator E. connexa. Eriopis connexa completed immature development on all prey species except on T. evansi, in which all individuals of predator died before reaching the pupal stage. Among prey species that allowed the immature development of E. connexa, T. urticae and M. persicae provided a faster development time to the predator. Oviposition days, longevity and fecundity of E. connexa on T. urticae and M. persicae were substantially longer/higher than on T. ogmophallos. Net reproductive rate (R0), intrinsic rate of increase (r), and finite rate of increase (λ) of E. connexa feeding on T. urticae and M. persicae were also higher than those on T. ogmophallos. Based on the overall performance of the ladybird, the order of suitability of prey species was M. persicae > T. urticae > T. ogmophallos > T. evansi.
