摘要: Omnivorous predatory Heteroptera are important biological control agents of pests in several crops. They can feed on plant food resources that may positively affect their characteristics. In the current paper, influence leaves and flowers predation rate omnivorous predator Macrolophus pygmaeus (Rambur) (Hemiptera: Miridae) was investigated. Its rates were recorded prey offered (a) a single leaf tomato, pepper or black nightshade (Solanum nigrum), (b) S. nigrum plus nigrum, respectively. all cases aphid Myzus persicae (Sulzer) (Homoptera: Aphididae) used as at densities 4, 8, 12, 16, 20 24 nymphs second instar. The experiments conducted petri dishes 25 ± 1°C consumption evaluated after h. M. significantly higher than those density items. Therefore, hypothesis increased should occur plants lower suitability for development reproduction not supported under our experimental conditions. flower availability did alter among nigrum. However, presence caused significant decrease leaves, eight Thus, provide with nutrient sources partially substitute consumption, practical implications control.
