Beneficial organisms overwintering in fallen leaves in fruit orchards

Popis výsledku v původním jazyce

Fruit orchards are agroecosystems with a great potential for an occurrence of the large number of arthropods, beneficial invertebrates included, throughout the year. This is due to a rich spatial arrangement of orchards, which offer a large number of ecological niches to invertebrates. Problematics of predator overwintering in orchards is a little explored area. Therefore, we investigated the number of individuals and predator species at pre-specified size area at the beginning and at the end of winter 2018/2019, where we collected fallen leaves from three types of orchards: cherry, pear and apple orchard. One year results showed us a lot of predator individuals, mainly spiders and ladybirds which overwinter in fallen leaves in orchards. We found 243 individuals of spiders belonging to 11 families and 60 ladybirds in cherry orchard; 113 individuals of spiders belonging to 12 families and 44 ladybirds in pear orchard; 202 individuals of spiders belonging to 11 families and 54 ladybirds in apple orchard. Our investigation shows, that fallen leaves in orchards offer important overwintering sites to wide variety of spiders and ladybirds, mainly seven-spot ladybird (Coccinella septempunctata), which could immediately react on the first pests occurred in orchards in the early spring.
