Mechanically coupled ears for directional hearing in the parasitoid fly Ormia ochracea.
An analytical model of the mechanical response of the ear to a sound stimulus is proposed which supports the claim that mechanical interaural coupling is the key to this animal's ability to localize sound sources. Expand
Effects of a tachinid parasitoid, Ormia ochracea, on the behaviour and reproduction of its male and female field cricket hosts (Gryllus spp)
After the larvae of the tachinid parasitoid fly entered the abdominal cavity, the host's mating, egg-laying and fighting ability (males) declined, probably due to the tissue damage wrought by the parasitoids. Expand
The mechanical basis of Drosophila audition.
By improving antennal sensitivity at low song intensities and reducing sensitivity when intensity is high, it brings about dynamic range compression in the fly's auditory system, relevant for close-range acoustic communication in Drosophila. Expand
The response of an insect parasitoid, Ormia ochracea (Tachinidae), to the uncertainty of larval success during infestation
Even though the success rate for larvae laid during the second mode of larviposition was low, the possibility of parasitizing more hosts appears to have selected for flies laying more larvae than is optimal if all the larvae successfully entered a single host. Expand

In analogy to vertebrate hair cells, the mechanosensory neurons of the fly serve dual, transducing, and actuating roles, documenting a striking functional parallel between the vertebrate cochlea and the ears of Drosophila. Expand

Motor-related electrical activity of Johnston's organ strongly suggests that mosquito hearing is improved by mechanoreceptor motility, similar to humans and other vertebrates. Expand
Tympanal travelling waves in migratory locusts
In the desert locust, the spatial decomposition of incident sound into discrete frequency components involves a tympanal travelling wave that funnels mechanical energy to specific tyMPanal locations, where distinct groups of mechanoreceptor neurones project. Expand
The evolutionary convergence of hearing in a parasitoid fly and its cricket host.
Through evolutionary convergence, these flies possess a hearing organ that much more resembles a cricket's ear than a typical fly's ear, allowing these parasitoids to take advantage of the sensory ecological niche of their host. Expand
Tympanal hearing in insects.
In insects that possess them, tympanal hearing organs may mediate the detection of predators, prey, and potential mates and rivals, depending on the species. Expand
Wing stridulation in a Jurassic katydid (Insecta, Orthoptera) produced low-pitched musical calls to attract females
Providing an accurate insight into paleoacoustic ecology, the low-frequency musical song of A. musicus was well-adapted to communication in the lightly cluttered environment of the mid-Jurassic forest produced by coniferous trees and giant ferns, suggesting that reptilian, amphibian, and mammalian insectivores could have also heard A.Musicus' song.
