ABSTRACT
The European pepper moth (Duponchelia fovealis, Lepidoptera, Crambidae, Spilomelinae) is an invasive pest of greenhouses in many countries, causing serious damages to horticultural plants. Coupled gas chromatographic-electroantennographic detection analysis of the female gland extract revealed two antennally active peaks. Using coupled gas chromatography-mass spectrometry (GC-MS), one was identified as (Z)-11-hexadecenal (Z11-16Ald); however, further analysis on different types of capillary columns indicated that the second active compound has two different isomers, (E)-13-octadecenal (E13-18Ald) and (Z)-13-octadecenal (Z13-18Ald). The approximate ratio of E13-18Ald, Z13-18Ald and Z11-16Ald in the crude pheromone gland extract was 1010.1, respectively. Single sensillum recordings showed that there was one sensory neuron that responded with a high amplitude spike to both E13-18Ald and Z13-18Ald, while another neuron housed in the same sensillum responded to Z11-16Ald. Field evaluation of the identified compounds indicated that the E13-18Ald was necessary to evoke the attraction of males; although the presence of Z13-18Ald and Z11-16Ald increased the catches in traps. The highest number of caught males was achieved when E13-18Ald, Z13-18Ald and Z11-16Ald were present in baits in the same ratio as in the female gland extract. This pheromone can be used in a monitoring strategy and could potentially lead to the development of mating disruption.
