Intraguild predation among spiders and their effect on the pear psylla during winter

Popis výsledku v původním jazyce

Generalist predators may provide biocontrol service if they are abundant in an agroecosystem, intraguild predation is low, alternative prey is scarce, and pest population increase is slow. These conditions are met in fruit orchards during winter and in early spring. Spiders of the genera Anyphaena and Philodromus remain active during winter and prey on pests, including overwintering Cacopsylla pyri. As these spiders belong to the same guild they can also disrupt their biocontrol potential via intraguild predation. Hence, we aimed here to assess predation frequency on Cacopsylla and among these spiders over the course of two winters. We investigated the width of the trophic niche and prey preference of the two winter-active spider species. We developed specific primers and investigated the actual predation by means of molecular methods (DNA detection of prey in the gut of spider predators). From a dozen of potential prey types (11 arthropod orders) offered in the laboratory, both Anyphaena and Philodr
