The current level of understanding of orientation mechanisms used by flying insects responding to pheromone sources, based almost entirely on studies of moths and flies, allows clear predictions to be made of how other, hitherto little-studied insect taxa, such as beetles (Coleoptera), should behave if the same mechanisms are used. Results are presented of the first test of such set of predictions, the effect of flight height on ground speed, on a beetle, Prostephanus truncatus (Horn… 

Visual ground pattern modulates flight speed of male Oriental fruit moth Grapholita molesta

These insects typically fly faster at higher elevations above a high‐contrast ground pattern, as predicted by the hypothesis, although the increase in speed is not sufficient to demonstrate quantitatively that they maintain constant visual angular velocity of the ground pattern.

Evidence of active or passive downwind dispersal in mark–release–recapture of moths

Test anemotaxis theory by analysing the data from a series of mark–release–recapture experiments where the wind direction was known and the insects were trapped using an irregular grid of pheromone traps, which provides evidence of a downwind component to the flight patterns of the released insects.

Honeybees change their height to restore their optic flow

This visuo-motor control scheme explains how honeybees can navigate safely along tunnels on the sole basis of OF measurements, without any need to measure either their speed or the clearance from the surrounding walls.

Odor Detection in Manduca sexta Is Optimized when Odor Stimuli Are Pulsed at a Frequency Matching the Wing Beat during Flight

The olfactory system of Manduca sexta may have evolved mechanisms to enhance odor detection during flight, where the effects of wing beating represent the norm, and this system may even exploit temporal structure in a manner similar to sniffing.

Modelling visual-olfactory integration in free-flying Drosophila

It is concluded that visual and olfactory responses of Drosophila are not independent, but that relatively simple interaction between these modalities can account for the observed visual dependence of odour source localisation.

Antennal lobe representations are optimized when olfactory stimuli are periodically structured to simulate natural wing beat effects

A general strategy for optimizing olfactory representations is suggested, which exploits the natural rhythmicity of wing beating by integrating mechanosensory and olfaction cues at the level of the AL.

Honeybees' Speed Depends on Dorsal as Well as Lateral, Ventral and Frontal Optic Flows

The present behavioral findings suggest how flying insects may succeed in adjusting their speed in their complex foraging environments, while at the same time adjusting their distance not only from lateral and ventral objects but also from those located in their dorsal visual field.

Prior classical olfactory conditioning improves odour-cued flight orientation of honey bees in a wind tunnel

This type of information transfer, from a Pavlovian associative context to an orientation task, might allow future foragers to acquire, within the hive, relevant information about the odours and food they will encounter during their later foraging bouts.

Fine-scale structure of pheromone plumes modulates upwind orientation of flying moths

IN studies of moths flying upwind to a pheromone source, attention has focused on the influence on flight orientation of the composition1,2 and concentration3,4 of the chemical message, and of

Flight behavior of scolytid beetle in response to semiochemicals at different wind speeds

The response of the striped ambrosia beetle,Trypodendron lineatum (Olivier) (Coleoptera: Scolytidae), to a semiochemical-baited funnel trap was studied in a wind tunnel and results suggest that T. lineatum are capable of responding to semiochemicals under varied wind conditions typically present in a forest.

Orientation of flying male Anobium punctatum (Coleoptera: Anobiidae) to sex pheromone: separating effects of visual stimuli and physical barriers to wind

Flying male woodworm, Anobium punctatum, are able to locate a source of female pheromone offered as a point source but land more quickly if the same odour source is presented on a model ‘tree’ (cylinder), which suggests this phenomenon may be more widespread.

An analysis of anemotactic zigzagging flight in male moths stimulated by pheromone

The zigzagging behaviour of male Plodia interpunctella flying up a plume of sex pheromone was investigated in a horizontal wind tunnel by detailed analysis of the moths' ground tracks, groundspeeds, orientations and airspeeds and it is inferred that the moth, although unable to sense the wind directly, are able to compensate for changes in wind speed.

Sex Pheromone Responses of the Oriental Beetle (Coleoptera: Scarabaeidae)

The synthetic female sex pheromone of the oriental beetle, Anomala orientalis Waterhouse, was evaluated in the field and in a sustained-flight tunnel and it was observed that peak activity occurs around sunset.

Responses of flying maleAnobium punctatum (Coleoptera: Anobiidae) to Female sex pheromone in a wind tunnel

A bioassay method is described for investigating the flying responses of beetles, both to their own sex pheromone and to the sex phersomone of S. paniceum, in order to determine whether male A. punctatum respond equally to the two peromone extracts, as in the previous walking assays.

Influence of stimulus dose and wind speed on the orientation behaviour of Prostephanus truncatus (Coleoptera: Bostrichidae) to pheromone

It is suggested that pheromone dose and wind speed are major influences on the flight behaviour of the larger grain borer, Prostephanus truncatus Horn, and the implications of this on the interpretation of field phersomone-baited trap catch data are discussed.

Even though up‐tunnel velocity increased with increased flight height, angular velocity of image motion did not and the relationship of preferred retinal velocities to optomotor anemotaxis is discussed.

Attraction of bark beetles (Coleoptera: Scolytidae) to a pheromone trap Experiment and mathematical models

The efficiency of the pheromone trap is shown to be rather low, and the data lend some support to the hypothesis that flight exercise increases the response of the beetles to phersomone.

Visual feedback in the control of pheromone-mediated flight ofHeliothis virescens males (Lepidoptera: Noctuidae)

Optimal upwind progression in pheromone-responding males occurred when image motion could be resolved both transversely (T), orthogonally to the longitudinal axis of the body relative to the horizontal plane of the environment, and longitudinally, along the body axis.
