Hearing in Insects

Neural Mechanism of Hearing in Insects

INTRODUCTION Since the work of Wever & Bray (1933) many electrophysiological studies have been made on sound reception in insects and it has been established that their receptive organs can readily detect the direction of sound and can discriminate its intensity, but not its frequency (Pumphrey, 1940; Autrum, 1955). More recently Haskell (1956, 1957), Haskell & Belton (1956), and Roeder & Treat...

Diversity and Abundance of Insects in Wukari, Taraba State, Nigeria

A field survey was conducted in Wukari, Taraba State to assess the diversity and abundance of insect species in selected habitats (residential, open field made up of grassland and an agroecosystem). Sampling were done biweekly using light, pitfall and yellow pan traps set in 3 replicates, 30 m apart. Insects recovered were wet preserved in 70% ethanol except butterflies and moths. Representativ...

Comparative Aspects of Hearing in Vertebrates and Insects with Antennal Ears

The evolution of hearing in terrestrial animals has resulted in remarkable adaptations enabling exquisitely sensitive sound detection by the ear and sophisticated sound analysis by the brain. In this review, we examine several such characteristics, using examples from insects and vertebrates. We focus on two strong and interdependent forces that have been shaping the auditory systems across tax...

HEARING LOSS IN HEMODIALYSIS PATIENTS

Inner ear cells are sensitive to some metabolic and hormonal disorders, but the relation between chronic renal failure (CRF), regular dialysis treatment (RDT) and sensorineural hearing loss (SNHL) is still a debatable field. The object of this paper was to verify the presence of SNHL in patients submitted to hemodialysis with different duration due to CRF and in those submitted to conservat...
