The relationship between the degree of infestation with Bactrocera oleae Rossi (Diptera: Tephritidae) and the volatiles released by the olive canopy
The olive fruit fly, Bactrocera oleae (Rossi), is the most economically important pest of the olive tree; the fly prefers some cultivars over others, although the reason for this is still unclear. Current research results indicate that volatile compounds of the olive tree have a greater influence on the fly's attraction to a host plant than the physical parameters of the olive fruit. Therefore, the aim of the study was to investigate the relationship between the degree of the olive fruit fly infestation and the volatiles released by the olive leaves and fruits of three cultivars with similar physical fruit parameters, grown in the same olive grove. Lastovka, Frantoio and Leccino cultivars were studied, HS-SPME/GC–MS was performed to determine the profile of volatiles in leaves and fruits and to investigate the relationship between volatiles and the olive fruit fly infestation. Frantoio was the olive cultivar with the highest infestation by the olive fruit fly (39.66 %), followed by Leccino (24 %) and Lastovka (5 %). Among total number of volatiles identified in the study (55), more were detected in the fruits (37) than in the leaves (26). Saturated hydrocarbons and terpenes were the most abundant volatile groups in the fruits, while terpenes were found the most abundant in the leaves. The amounts of (E)-4,8-dimethylnona-1,3,7-triene and heneicosane were highest in the olive fruits of all cultivars tested. Heneicosane and eicosane were mainly released from ripe fruits and strongly correlated with the degree of infestation with the olive fruit fly. In addition, henicosane was the most abundant volatile compound in ripe fruits, along with 2,6-di-tert-butyl-4-methyl-phenol. Therefore, the results of the study suggest that fruit-derived volatiles have the greatest impact on the attraction of the olive fruit fly. The use of plant volatiles as attractants could be an effective tool for the sustainable control of olive trees to reduce the damage caused by the olive fruit fly while avoiding negative impacts on the environment and biodiversity.
期刊介绍:
Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
