Dc. Robacker, Attraction of wild and laboratory-strain Mexican fruit flies (Diptera : Tephritidae) to two synthetic lures in a wind tunnel, FLA ENTOMOL, 82(1), 1999, pp. 87-96
Attraction of laboratory-strain Mexican fruit flies, Anastrepha ludens (Loe
w), and wild-type flies to two synthetic lures was evaluated in a wind-tunn
el. The lures were BioLure(R) (ammonium acetate and putrescine) and AMPu (a
mmonium carbonate, methylamine HCl, and putrescine). In one experiment, wil
d-type flies from the state of Nuevo Leon, Mexico, were evaluated against l
aboratory-strain flies that originated in Nuevo Leon. Yellow panels contain
ing AMPu attracted >2.5 times more females and >3.5 times more males of bot
h fly strains than panels containing BioLure(R). In another experiment. wil
d-type Hies from the state of Chiapas, Mexico, were evaluated against the N
uevo Leon laboratory strain. Results of this experiment were similar to the
first except the differences in attractiveness between AMPu and BioLure(R)
to flies of both strains were less pronounced The difference in relative a
ttractiveness of AMPu and BioLure(R) in the two experiments was related to
the time of year when the experiments were conducted rather than to inheren
t differences between the fly strains. In both experiments, BioLure(R) was
about two times more attractive to females than to males whereas AMPu was o
nly slightly more attractive to females. Both lures rvere more attractive t
o laboratory-strain flies than to wild-type flies from either region of Mex
ico.
