Attraction modulated by spacing of pheromone components and anti-attractants in a bark beetle and a moth
(2011) In Journal of Chemical Ecology 37. p.899-911- Abstract
- Orientation for insects in olfactory landscapes
with high semiochemical diversity may be a challenging
task. The partitioning of odor plumes into filaments that are
interspersed with pockets of ‘clean air’ may help filament
discrimination and upwind flight to attractive sources in the
face of inhibitory signals. We studied the effect of distance
between odor sources on trap catches of the beetle, Ips
typographus, and the moth, Spodoptera littoralis. Insects
were tested both to spatially separated pheromone components
[cis-verbenol and 2-methyl-3-buten-2-ol for Ips; (Z,E)-
9,11-tetradecadienyl acetate and (Z,E)-9,12-tetradecadienyl

anti-attractant sources [non-host volatile (NHV) blend for
Ips; (Z)-9-tetradecenyl acetate for Spodoptera]. Trap catch
data were complemented with simulations of plume structure
and plume overlap from two separated sources using a photo
ionization detector and soap bubble generators. Trap catches
of the beetle and the moth were both affected when odor
sources in the respective traps were increasingly separated.
However, this effect on trap catch occurred at smaller
(roughly by an order of magnitude) odor source separation
distances for the moth than for the beetle. This may reflect
differences between the respective olfactory systems and
central processing. For both species, the changes in trap
catches in response to separation of pheromone components
occurred at similar spacing distances as for separation of
pheromone and anti-attractant sources. Overlap between two
simulated plumes depended on distance between the two
sources. In addition, the number of detected filaments and
their concentration decreased with downwind distance. This
implies that the response to separated odor sources in the
two species might take place under different olfactory
conditions. Deploying multiple sources of anti-attractant
around a pheromone trap indicated long-distance (meter
scale) effects of NHVon the beetle and a potential use for
NHV in forest protection. (Less)
