NON-TARGET LEPIDOPTERAN SPECIES IN PHEROMONE TRAPS BAITED WITH ATTRACTANTS FOR SEVERAL TORTRICID MOTHS

The aim of this paper is to present the non-target species caught in the traps baited with synthetic pheromones of the species Cydia pomonella, Grapholita funebrana, Grapholita molesta, Archips podana, Adoxophyes orana, Tortrix viridana and Gravitarmata margarotana, in the frame of some experiments conducted during the years 1989-1990 in order to identify sexual attractants for the main conophagous Lepidoptera in Romania. At the same time we assessed the selectivity of these products and identified the compounds which could be used as sexual attractants for different tortricid species. Deploying pheromone traps in coniferous mature tree stands or seed orchards having in their neighbourhood fruit trees or deciduous forests, only 5 reference species and 30 non-target species have been caught, 23 of them being tortricid moths. The selectivity (specificity) of the used synthetic pheromones was rather low. However, this should not be a problem in the current works accomplished with atraPOM, atraPOD, atraRET and atraVIR products, because the species attracted are quite easily distinguished using morphological characteristics. On the other hand, the people using atraFUN and atraMOL pheromones could have insurmountable difficulties to establish the abundance of target species and other aspects, because these pheromones attrac
