Antennal responses of black plum sawfly (Hoplocampa minuta) to European plum (Prunus domestica) flower volatiles

Abstract Black plum sawfly ( Hoplocampa minuta ) is an important pest species of Prunus domestica ). In organic orchards, the yield loss caused by H. larval damage can reach almost 100% occasionally. Adults feed on pollen and nectar flower; therefore, we hypothesize that, besides visual cues, also olfaction plays role in habitat host finding. To understand chemical communication mediated flower volatiles to black sawflies, investigated signals released from flowers, which trigger peripheral physiological responses adult sawflies. First, using gas chromatography coupled with electroantennography (GC-EAD), selected 18 physiologically active compounds headspace volatile collection triggered male female antennae. Subsequently, determine volatilome identified those compounds, elicited responses, mass spectrometry (GC-MS). These antennally components could be candidates for potential kairomone, later used attracting males females contribute developing pesticide-free, effective monitoring lure kill strategy against this pest.
