The observations were carried out in the south-eastern part of Poland in apple orchards with different management systems and their surroundings. During that period, 816 individuals of the Coccinellidae belonging to 10 species were collected in apple orchards and 670 specimens (8 species) in their neighbourhood.
In the orchards with IPM, more beetles were recorded in their surroundings than in the orchards; presumably, use of chemical treatments in the IPM orchards negatively affected the species richness and the number of coccinellids while in the surroundings the presence of varied vegetation (shrubs, trees and herbaceous plants) contributed to the increase in the species richness of the Coccinellidae. On the ecological site, however, more ladybird beetles were collected in the orchard than in its neighbourhood.
The species which dominated the coccinellid assemblages in the orchards and their surroundings were Coccinella septempunctata L. and Harmonia axyridis (Pall).
The research showed that in the case of coccinellids, the impact of the vegetation surrounding the orchards on the presence of ladybugs in the orchard was smaller than the management system.
