Antennal resolution of pulsed pheromone plumes in three moth species.
Male antennae of Cadra cautella, Pectinophora gossypiella, and Spodoptera exigua were presented with 20-ms-duration pulses of their two-component pheromone at rates of 1 to 33 Hz. Fourier analyses of electroantennograms resolved the temporal structure of trains of pheromone filaments delivered at up to 33 Hz for C. cautella and S. exigua and 25 Hz for P. gossypiella. Pheromone components tested...
متن کاملDynamic properties of antennal responses to pheromone in two moth species.
Dynamic properties of pheromone plumes are behaviorally important in some moths for inducing upwind flight, but little is known about the time-dependent properties of odor transduction or the mechanisms that limit receptor dynamic sensitivity. We stimulated male antennae of two moth species, Cadra cautella and Spodoptera exigua, with pheromone plumes in a wind tunnel while recording electroante...
متن کاملElectroantennographic resolution of pulsed pheromone plumes in two species of moths with bipectinate antennae.
Trains of 20-ms-duration pulses of pheromone were delivered at rates of 1-33 Hz to antennal preparations of males of Bombyx mori and Lymantria dispar, two moth species with bipectinate antennae. Resolution of rapidly pulsed plumes of pheromone was not compromised by a complex antennal morphology or by moderate changes in wind speed (25-50 cm/s). Fourier analysis of the electroantennograms resol...
متن کاملInfestation of Stored Saw Palmetto Berries by Cadra Cautella (lepidoptera: Pyralidae) and the Host Paradox in Stored-product Insects
The almond moth, Cadra cautella (Walker), is a common storage pest known to infest a wide range of dried plant materials, and it has been recorded from a warehouse in Florida during storage of dried passion-flower ( Passiflora incarnata L.) and dried saw palmetto berries Serenoa repens (Bartram) Small. Its status as a pest of stored saw palmetto was confirmed by trapping in a second warehouse u...
متن کاملA pulsed cloud of sex pheromone elicits upwind flight in male moths
Male oriental fruit moths do not fly upwind in a continuous uniform cloud of pheromone, but readily do so when the cloud is pulsed at 1 or 0 51s or when a plume from a point source of pheromone is placed within the continuous cloud It is suggested that males of moth species that require such fluctuating pheromone stimulation for upwind flight will normally receive it from a filamentous, point-s...
