Captures of oriental fruit moth, Grapholita molesta (Lepidoptera: Tortricidae), in traps baited with host-plant volatiles in Chile [Research data]
MetadataShow full item record
Studies in Australia and China identified host-plant volatile blends from peach and pear that captured relatively high numbers of Grapholita molesta (Busck). To determine if these blends are attractive in other countries and relative to each other, the two host-plant blends, a laboratory blend identified in Switzerland, and a new "Total blend" made by mixing components of all three blends, were field tested in Chile for the first time. Same solvent type, concentrations and dispensers as in the original studies, plus an additional concentration and solvent, were used. Only the Swiss blend at the low dose in n-hexane captured significantly more males than the solvent traps, albeit in very low numbers (1.46 ± 1.46 mean ± SEM males/trap/week). Furthermore, host-plant blends decreased male captures in sex pheromone traps, and the effect was dose-dependent for the Chinese and Total blends. A laboratory flight-tunnel test confirmed the lack of response of G. molesta males to the Australian, Chinese and Swiss plant blends, but in the flight tunnel males responded sooner and in higher numbers to mixtures of sex pheromone and host-plant blends than to sex pheromone alone.

Role of plant volatiles and hetero-specific pheromone components in the wind tunnel response of male Grapholita molesta (Lepidoptera: Tortricidae) to modified sex pheromone blends [Research data] Ammagarahalli Munishamappa, Byrappa; Chianella, Lucia; Gomes, Pedro; Gemeno Marín, César (Universitat de Lleida, 2016-07-21)The response of males of the moth Grapholita molesta to sex pheromone and plant volatiles was tested under laboratory conditions in a wind tunnel.
