Can the pheromones of predators modulate responses to herbivore‐induced plant volatiles?

摘要: Biological control of greenhouse pests has been successfully developed and applied. In crops, several entomophagous species (predators parasitoids) are used simultaneously in the crop cycle. One important aspect these which represent modified ecosystems, is interactions among complexes species, including plants, phytophagous insects, predators. The chemical relationships (semiochemicals: pheromones kairomones) likely play an role crops; however, few studies have focused on relationships. aim this study was to analyse importance semiochemicals. Three groups laboratory trials were conducted with two predatory species: Nabis pseudoferus Nesidiocoris tenuis (Hemiptera: Nabidae Miridae, respectively). results first group indicated that adult females both more attracted herbivore-induced plant volatiles (HIPVs) than they plants or artificial damage. Based second trials, triggered attraction for conspecifics. Finally, based same changed modulated responses HIPVs. implications biological pest greenhouses further discussed.
