Smell and Hearing in Moths

Pheromone components and active spaces: what do moths smell and where do they smell it?

The pheromone-mediated flight behavior of male Oriental fruit moths was observed in the field to test the hypothesis that male activation far downwind of a female is initiated by the major, or most abundant, component of the pheromone blend. Males responded at significantly greater distances to the three-component pheromone blend produced by females than to the major component alone or to eithe...

Hearing in hooktip moths (Drepanidae: Lepidoptera).

This study presents anatomical and physiological evidence for a sense of hearing in hooktip moths (Drepanoidea). Two example species, Drepana arcuata and Watsonalla uncinula, were examined. The abdominal ears of drepanids are structurally unique compared to those of other Lepidoptera and other insects, by having an internal tympanal membrane, and auditory sensilla embedded within the membrane. ...

Hearing and bat defence in geometrid winter moths.

Audiograms and behavioural responses to ultrasound reveal that male geometrid winter moths (Agriopis and Erannis spp.; Ennominae, and Alsophila aescularia; Oenochrominae), which have large wings and a slow flight, have good, broadly tuned ultrasonic hearing with best frequencies at 25-40 kHz, coinciding with the frequencies used by most sympatric aerial-hawking bats. Ultrasonic pulses (27 kHz 1...

Hearing in Notodontid Moths: a Tympanic Organ with a Single Auditory Neurone

1. Notodontid moths possess paired tympanic organs basically similar to the ears in other noctuoid families, but with a single auditory .A cell. The A cell and the non-auditory B cell were studied anatomically by infusion of C0CI2 and physiologically by recordings from the tympanic nerve. 2. The response of the A cell is determined by intensity parameters and temporal parameters of an ultrasoni...
