Abstract

Tuta absoluta Meyrick quickly developed into a significant pest of tomatoes worldwide. While the mirid bugs Macrolophus basicornis (Stal), Engytatus varians (Distant) and Campyloneuropsis infumatus (Carvalho) prey on this tomato borer, their biology have not been well characterized. Using a mixture of T. absoluta eggs and larvae as food on tomato, mirid life histories were studied. Nymphs and adults successfully used T. absoluta as prey, although significant differences in biology of the species were observed. Campyloneuropsis infumatus and M. basicornis were quickest and slowest to become adult at 16 and 19 days, respectively. Nymphal survival was high and varied from 70 to 75 %. Female biased sex ratios were observed for C. infumatus (0.80) and M. basicornis (0.71), but not for E. varians (0.56). Intrinsic rates of increase for C. infumatus, E. varians and M. basicornis were 0.11, 0.10 and 0.11 respectively. Our results indicate rapid development and population increase of these three mirids, making them interesting candidates for biological control of T. absoluta on tomato.
