“…Males responded to asparagus on the first day after emergence and females responded to the host-plant/male pheromone blend as early as the second day after emergence. This finding is in agreement with the fact that females contain chorionated oocytes upon emergence (Thibout & Auger, 1998), an uncommon finding in tephritid fruit flies (Christensen & Foote, 1960), and thus are able to lay eggs quickly after emergence. This feature may be related to the short lifespan of the non-frugivorous tephritid species (Headrick & Goeden, 1998) and/or more likely to a particularity of the host plant such as the rapid growth of the spear on which the female lays.…”

“…Experiments were carried out either in the morning during the 4th, 5th, and 6th hour of the photophase or in the afternoon during the 9th, 10th, and 11th hour of the photophase. The afternoon session coincides with the male calling period (Thibout & Auger, 1998). Individual flies were used only once without previous contact with a congener or with the host plant.…”

The role of various olfactory and visual stimuli was studied in host-plant finding by the asparagus fly Plioreocepta poeciloptera (Schrank), a monophagous monovoltine tephritid causing serious damage to asparagus spears. Volatiles released by asparagus plants were extracted by diethyl ether after cryotrapping concentration, and identified by gas chromatography-mass spectrometry. Twelve of the 13 compounds identified were tested using electroantennography to measure the response of the fly. Behavioural response was analysed using two different flight tunnels according to circadian rhythm, age and sex of adults, presence of the plant and of different coloured lures, presence of a male congener, or exposure to four pure asparagus odour compounds that elicited responses in electroantennography, i.e. hexanal, (E)-2-hexenal, (Z)-2-hexen-1-ol and decanal. Data showed that males locate the host plant more quickly than females. Females are attracted mainly by the blend of plant odour and male pheromone. Both sexes respond to a complex of stimuli only during the afternoon. These findings will be helpful in developing new and effective approaches to control this pest insect.

Adult male asparagus flies exhibit typical calling behaviors (suggestive of pheromone production) during which they emit a single volatile compound that was identified as isopropyl (S)-5-hydroxyhexanoate. In laboratory bioassays, synthetic samples elicited an arrestant response in females, but did not appear to attract females. On the other hand, the synthetic material attracted conspecific males in olfactometer bioassays.
