Temperature-Driven Selection of Predatory Mirid Bugs for Improving Aphid Control in Sweet Pepper Crops

Recent studies have suggested that predatory mirid bugs may be an effective alternative for controlling aphids in sweet pepper greenhouses. This study examined the effect of three constant temperatures (18, 24, and 30 °C) on life history traits species Nesidiocoris tenuis, Macrolophus pygmaeus, Dicyphus bolivari, preying aphid Myzus persicae nicotianae plants. As temperature increased, survival rate decreased M. pygmaeus D. while N. it was opposite, their increased. When considering all biological studied together, estimated intrinsic increase (rm) as increased bolivari. In contrast, tenuis. These results suggest bolivari are better adapted to lower than which is more warm temperatures. The implications these improving control greenhouses through use discussed relation different regimes.
