“…Also, male mating success was similar whether females were courted from the left, right, front or back sides. Further research is needed on the possible adaptive advantage (e.g., faster location of the partner due to side-biased production of olfactory cues, also see Canale et al, 2013) arising from lateralization of courtship traits in olive fruit flies.…”

“…On this basis, in Experiment 1 we investigated if males and females of the olive fruit fly showed population-level lateralization of boxing displays and if this led to enhanced fighting success. After having established a territory, males perform courtship displays that include sex-specific olfactory cues and wing vibrations, then attempt copulation with females (Benelli et al, 2012;Canale et al, 2013). In Experiment 2 we evaluated if olive fruit fly males showed any side bias in courtship approaches toward females, and if this had any effect on male courtship duration, mating success, or copulation duration.…”

“…According to Scarpati et al (1993), α-pinene emanating from olive leaves is a repellent cue in olive fly oviposition, which may be due to its higher concentration than those evaluated by Gerofotis et al (2013). The mature males produce (Z)-9-tricosene, which attracts females (Canale, Germinara et al, 2013;Carpita et al, 2012), whereas young immature males produce DSU as the females and can indirectly benefit by distracting mature males from females (Benelli, Bonsignori, Stefanini, Raspi, & Canale, 2013).…”

The olive fly, Bactrocera oleae (Rossi), is the main pest of olive, a host tree that thrives under conditions of high and direct sun exposure. Although the effect of the olive fruit on the reproduction of the fly has been studied to some extent, there is little knowledge on the effect of light. In the present work, we studied the effect of the presence of olive fruit and light intensity on mating and subsequent egg production of olive flies at 25°C and a photoperiod regime of L : D 16 : 8. The results showed that contact of the adults with the fruit, or exposure to fruit odours, favoured both the extent and the duration of mating. This effect was higher at low than at high light intensity. However, egg production following female access to olive fruit was more favoured by high light intensity. Our results also showed that fruit contact and/or volatile fruit stimuli significantly affect mating and egg production of the olive fly, and that this influence is modulated by light conditions. The results contribute to a better understanding of the reproductive behaviour and population dynamics of the olive fly. On a more practical scale, the results provide important insights into how to improve mass rearing of the fly.

Plant nutritional quality and chemical characteristics may affect the fitness of phytophagous insects.Here, the olfactory preferences of Bactrocera oleae (Rossi) females toward olives with different maturation and infestation status were evaluated in three cultivars: Ottobratica, Roggianella and Sinopolese. Volatile profiles from olives were identified by SPME/GC-MS. Choice tests were performed to determine the responses of B. oleae adult females toward fruits and pure chemicals linked to infestation degree. Cultivar was the main source of variability explaining the differences recorded in volatile emissions. Moreover, three VOCs [β-myrcene, limonene and (E)-β-ocimene] were associated to infestation status across all olive varieties. In choice-tests, B. oleae females always preferred the olfactory cues from low-infested over high-infested fruits. Therefore, choice-tests using synthetic VOCs, emitted in greater amount by high-infested fruit, were arranged in order to identify putative B. oleae kairomones. While females were indifferent to β-myrcene, the highest dosages of limonene and (E)β-ocimene were unfavoured by the tested flies, which preferentially moved toward the empty arm of the Y-tube. Furthermore, females preferred the lowest concentration of β-ocimene compared to the highest one. These results supported our hypothesis that fruit VOCs may serve as kairomones for female flies.Environmental conditions, food availability and ovipositional sites are crucial for phytophagous-insect survival 1,2 . The nutritional quality and the attractiveness of plants may influence the fitness of herbivores and be a key factor for oligophagous species, which can rely on a restricted number of host-plants 3,4 . Therefore, the recognition of suitable ovipositional sites is critical for several fruit flies 5,6 .Bactrocera oleae (Rossi) (Diptera: Tephritidae), commonly known as the olive fruit fly, is a strictly monophagous pest, which can feed exclusively on Olea species. The larval stages feed and develop solely inside olive drupes, excavating galleries inside the pulp. The fully developed larvae open an exit hole on the olive surface and usually pupate outside the fruit. During the oviposition process, B. oleae females carefully choose suitable fruit for oviposition, either performing aggressive behaviours toward conspecifics to gain and maintain the oviposition site 7 . In the Mediterranean area, the olive fruit fly population commonly increases during summer season until the harvest period. Depending on climate conditions, B. oleae produce from 2 to 7 generations during the favourable season, although this fly can reproduce also during winter in mild climates 8 . The olive fruit fly is considered the key pest of olive crop (Olea europea L.), causing great qualitative and quantitative yield loses, as well as premature fruit drop. The presence of ovipositional puncture and/or active infestation can decrease or even nullify the value of table olives and seriously reduce oil yield and quality 9,10 . Furthermore, the olive frui...
