Title: Laboratory evaluation of effects of powdered sulphur on the oviposition, fruit detection and behaviour of Drosophila suzukii (Diptera: Drosophilidae) on strawberry
Abstract: peaches) are the crops most susceptible to infestation.In Andalusia (southern Spain), D. suzukii was fi rst detected in 2012 in the province of Huelva.As over 80% of the berries in Spain are produced in Huelva, they are an important socio-economic driver in this region.Damage of around 80% of the strawberry crop, 100% of the cherry crop and 100% of organic crops were detected relatively shortly after D. suzukii arrived in Spain (Sorribas, 2013).In conventional farming D. suzukii is mainly chemically controlled in Europe using organophosphorates, pyrethroids and spinosyns.However, using these insecticides has consequences in terms of resistance (Bruck et al., 2011;Smirle et al., 2017;Gress & Zalom, 2019) and environmental pollution, is detrimental to benefi cial arthropods, incompatible with organic management and violates the MRL (maximum residue limit) zero tolerance policy in Laboratory evaluation of effects of powdered sulphur on the oviposition,
