Figure 1.
This shows the standard control devices against which new designs were compared.
Each is flanked by an electric net to catch flies which circle the device but do not land. Electrified black target with flanking net (A) and a biconical trap with flanking net (B).
Figure 2.
The experimental design used to investigate G. f. fuscipes circling or landing on an object.
3-D object with (A) and without (B) flanking net.
Table 1.
Detransformed mean catches from the experiments to investigate the effect of target size on tsetse fly catches (ANOVA data is given in supplementary Table S1).
Figure 3.
Landing or entering response for tsetse on a standard target 1m2 (ST), a small 25×25cm target (TT) or biconical trap (T).
For devices with a flanking net, landing or entering responses were estimated by expressing number caught landing on the target or entering the trap as a percentage of the total (device+flanking net) catch. For unaccompanied traps and targets, capture efficiency was estimated by expressing the mean catch of the trap or target as a proportion of the mean catch from a trap+flanking net. A = G. p. gambiensis at Solenzo; B = G. p. gambiensis at Folonzo; C = G. tachinoides; D = G. f. quanzensis; E = G. f. fuscipes. *Data for G. f. fuscipes derived from Lindh et al., 2009.
