| Three new prototype cloth traps, (S1-S3), were developed
during studies of the behavioural ecology of G. swynnertoni in Kenya and Tanzania
during 1996-97. The traps were compared in latin square experiments relative to the
regular biconical trap as a standard and a selection of other conventional tsetse traps.
Observations were also made on fly behaviour in the vicinity of traps using electric nets
and sticky materials. When baited with acetone and 1-octen-3-ol, the S1 trap was 3.5 times
as effective in catching G. swynnertoni in Kenya as the biconical trap. In
Tanzania, the relative performance of the S1 and biconical traps differed; also, both
traps were found to be inferior to an all-black, sticky 1-m2 target. A second
prototype (S2) performed slightly better than the biconical trap, but was still inferior
to the black target. The final prototype (S3) was 2.9 times as effective as the biconical
trap and performed as well as the black target. |
