“…The results obtained thus confirmed a positive impact of wild plants in the vicinity of orchards on the increase of parasitoid abundance in orchard habitats. A previous study by Miliczky and Horton [2005] proved that diverse wild plant life around an orchard is a favourable habitat for advantageous entomofauna and positively influences its occurrence in agrocenoses. Also Debras et al [2006] indicated a positive correlation between a varied plant life of hedges in the vicinity of pear orchards and the entomophages in those orchards.…”

Plant communities which form orchard edges are a vital element of ecological infrastructure enriching these agrocenoses. The research was conducted in an orchard environment made up of apple orchards and their edges in the form of agricultural cultivations, tree clumps and a road lined with trees and shrubberies. The study aim was to determine the impact of the orchard edge plant diversity onto the number and abundance of Ichneumonidae subfamilies in the orchards. The study showed that orchard environments made up of an apple orchard and edge plants of various species create better living conditions for Ichneumonidae parasitoids than the environment of an orchard and neighbouring agricultural cultivations. The diversity of orchard edge plants positively influences the abundance of the Ichneumonidae subfamilies rather than the number of subfamilies in the orchard. In the orchard habitat the following dominant subfamilies were found: Campopleginae, Cryptinae, Orthocentrinae and Pimplinae. These entomophages may control the abundance of pests infesting orchards.

“…Semi-natural habitats provide shelter, reproduction and overwintering sites for agricultural insects, thus serve as sources of cyclic recolonisation of agricultural fields after soil cultivation, pesticide applications or harvest (Holland et al, 2016;Miliczky and Horton, 2005;Wissinger, 1997). Conversely, pests and their natural enemies reaching high abundances in agricultural fields can also disperse in opposite direction into semi-natural habitats (Tscharntke et al, 2012).…”

Landscapes, orchards, pesticides-Abundance of beetles (Coleoptera) in apple orchards along pesticide toxicity and landscape complexity gradients. -Agriculture, Ecosystems and Environment, 247, AbstractLandscape composition may influence biodiversity and ecosystem services in agricultural fields.Hitherto, most studies have focused on annual crops and the available information on the impacts of landscape structure in orchards is sparse. In this study, we evaluated the effects of pesticide use as cumulative toxicity on pest and predatory beetle (Coleoptera) assemblages in the canopy of apple orchards surrounded by different proportion of semi-natural vegetation, crop fields and settlements in Hungary. Laboratory data suggest that increasing pesticide toxicity negatively affects predators (coccinellids), but we did not find such a pattern. Supposedly, the effect of pesticides was masked by the continuous recolonisation of orchards from the surrounding landscape. On the contrary, for the less mobile pest species [Anthonomus pomorum, Phyllobius oblongus (Curculionidae)] we did find a decline in abundance along the gradient of increasing pesticide toxicity. Landscape composition around the orchards significantly influenced the abundance of predatory, fungivorous and tourist species, but had no effect on pests. Contrary to expectations, however, semi-natural habitats had a minor effect compared to arable fields, orchards and settlements which habitat types had various effects on the abundance of different coleopteran groups and species. For example, Harmonia axyridis (Coccinellidae) abundance was positively affected by its overwintering sites, i.e. human settlements in spring, seminatural forests in summer, and arable fields in autumn. The mass immigration of other predatory, fungivorous and tourist species from the surrounding arable fields into the orchards started from July with senescence and harvesting of arable crops. These results suggest that arable fields, other orchards and settlements might be more important sources of colonisation for natural enemies in orchards than certain semi-natural habitats.

“…Oatman et al (1964) found in 764 insect species on apple trees.

A common limiting factor in these studies is the methods of capture and collection of arthropods.…”

Occurrence of arthropods on abandoned apple trees was studied in 2010 and 2011. The research was carried out in South Moravia (Czech Republic). Two sites were selected within this area -apple trees (Malus domestica) in an alley along a road and an abandoned apple orchard. At each location, arthropods were collected from 5 separate trees. Deltamethrin was applied into the treetops using a fogger. The killed arthropods were collected 15 minutes a er the application. From among the collected data, 48 families were determined in accordance with a generalized linear model with a logarithmic-link function and Poisson distribution. As a result it was found that 33 families have signifi cantly higher abundance in the abandoned orchard and 9 families in the alley. According to the Shannon-Wiener index, diversity of families was higher in the alley in both years
