Mechanisms of Odor Coding in Coniferous Bark Beetles: From Neuron to Behavior and Application
Figure 7
(a) Lindgren funnel traps (19-funnel size) were used in the vertical spacing tests with Ips typographus. Dispensers positioned under grey cups. (b) A Lindgren trap (5-funnel size) was attached to a wind vane in the horizontal spacing tests to ensure constant distance between plumes. (c) Pipe trap surrounded by eight nonhost volatile dispensers in the antiattractant background tests. (d) Soap bubble visualization of vertical plume overlap at a spacing distance of 48 cm. Distance between black poles = 1 m (modified from [61]).
