Predatory arthropod community composition in apple orchards: Orchard management, landscape structure and sampling method

Abstract: Studies on predatory arthropods in agricultural areas seldom include Diptera other than hoverflies, partly because common sampling methods are less effective for capturing species that easily fly off when disturbed. To study the effect from this bias when describing the predator community, we compared traditional beat sampling of K E Y W O R D S Diptera, Dolichopodidae, Hybotidae, integrated pest management, organic production This is an open access article under the terms of the Creative Commons Attribution L… Show more

“…arthropod behaviours(Deiner et al, 2017;Todd et al, 2020). Hence, the utilisation of either technique on its own has its limitations for arthropod diversity assessment and forthcoming studies could consider employing both in unison to get a better overview.Implications on orchard managementsKnowledge on beneficial and detrimental arthropods visitors to apple orchards is crucial to improving management techniques(Hambäck et al, 2021). Our study detected the presence of two important apple pests, Operophtera and Yponomeuta moths, that feed on developing apple fruitlets and leaves which can result in high economical losses if not controlled(Svensson et al, 1999; CFIA, 2006;Turner et al, 2010).…”

“…Increasing the number of biological and technical replicates, albeit at an increased cost and time, can also help to better detect rare and cryptic species(Deiner et al, 2017;Ruppert et al, 2019). DNA traces in flowers may be shortlived and inclusion of additional sampling in the afternoons may better capture traces of dayactive flower visitors.Knowledge on beneficial and detrimental arthropods visitors to apple orchards is crucial to improving management techniques(Hambäck et al, 2021).

“…Hence, the differences in the catches between the two sampling methods in our study may reflect differences in behaviour and activity of species groups (Doxon, Davis and Fuhlendorf, 2011). As such, sweep netting and sticky traps sample a different arthropod community (Schmidt, O'Neal and Dixon, 2008;Hambäck et al, 2020), and this may blur relationships between arthropod abundance, insecticide intensity and landscape context.…”
