Monitoring of three Hoplocampa sawfly species in plum orchards

Abstract

Abstract Three sawfly species (Hoplocampa minuta, Hoplocampa flava, Hoplocampa fulviicornis) have been monitored in plum orchards during the flowering period in three consecutive years at three different locations in Hungary using chromotropic white sticky traps. Black and yellow sawflies (H. minuta and H. flava) are one of the most important pests in plum orchards, however plum-fruit sawfly (Hoplocampa fulvicornis) has not yet been documented from plum orchards in Hungary. In almost all locations and years, H. minuta was the most dominant species, except in Cegléd, 2014, where H. flava was the most abundant one. In terms of sex ratio, in all three species, more males than females were caught in the traps except in 2016 at Érd, where more H. flava females flew into the traps.
