Ceratitis rosa

C. rosa can be monitored by traps baited with male lures. Like Ceratitis capitata, and members of subgenera Ceratitis and Pterandrus in general, it is attracted to trimedlure and terpinyl acetate, but not methyl eugenol or cue lure. It is also very sensitive to enriched ginger oil (EGO) lure (Mwatawala et al., 2015;Manrakhan et al., 2017). The responses to baits of 16 Ceratitis species were tabulated by Hancock (1987).
Trimedlure (t-butyl 4(or 5) chloro-2-methyl cyclohexane carboxylate) is the most widely used lure for C. capitata and the following information could also be relevant for C. rosa. The history of trimedlure development and the problems of isolating the best of the eight possible isomers was discussed by Cunningham (1989). The lure is usually placed on a cottonwool wick suspended in the middle of a plastic trap that has small openings at both ends. Suitable traps were described by White and Elson-Harris (1994). Lure can either be mixed with an insecticide or a piece of paper dipped in insecticide can be placed in the trap. Traps are usually placed in fruit trees at a height of ca. 2 m above ground and should be emptied regularly as it is possible to catch hundreds of flies in a single trap left for just a few days, although the lure may remain effective for a few weeks.
A detailed study of trap position effects was carried out by Israely et al. (1997). A review of the biological aspects of male lures was presented by Cunningham (1989) and the use of lures was described more fully by Drew (1982). A trapping system used to monitor for possible introductions of C. capitata into New Zealand has been described by Somerfield (1989) and should also be effective for C. rosa. The possibility of the development of pheromone based trapping systems was discussed by Landolt and Heath (1996) and it may be possible to extend that approach to C. rosa. Trapping efficiency of C. capitata is also enhanced by the use of fluorescent colours, particularly light green (Epsky et al., 1996). This may also apply to C. rosa.
Recent comparative research on attraction sensitivity of C. rosa by using different lures, has shown that enriched ginger oil (EGO) lure is an effective attractant for C. rosa (Manrakhan et al., 2017) and can actually be a more sensitive attractant than trimedlure (Mwatawala et al., 2015).
