Sex-Linked Pheromone Receptor Genes of the European Corn Borer, Ostrinia nubilalis, Are in Tandem Arrays
TLDR
The hypothesis that generation of additional copies of OR genes can increase the potential for male moths to acquire altered specificity for pheromone components, and accordingly, facilitate differentiation of sex phersomones is supported.
Moths produce extremely quiet ultrasonic courtship songs by rubbing specialized scales
TLDR
A mechanism for producing extremely low-intensity ultrasonic songs adapted for private sexual communication in the Asian corn borer moth, Ostrinia furnacalis, may point to a whole undiscovered world of private communication, using “quiet” ultrasound.
Moths are not silent, but whisper ultrasonic courtship songs
TLDR
Although largely unknown because it is so inconspicuous, acoustic communication using low intensity ultrasound appears to be widespread among hearing moths, and acoustic communication may be the norm rather than the exception.
Ultrasonic courtship song in the Asian corn borer moth, Ostrinia furnacalis
TLDR
It is reported that male- produced ultrasound serves as a courtship song in the Asian corn borer moth, O. furnacalis, and deaf females showed more ‘rejection’ and less ‘acceptance after walking’ than hearing females, indicating that the detection of male-produced ultrasound plays an important role in the acceptance of a male.
Variation in Courtship Ultrasounds of Three Ostrinia Moths with Different Sex Pheromones
TLDR
The results suggest that concordant evolution in sexual signals such as courtship ultrasounds and sex pheromones occurs in moths, and that ultrasound and phersomone communications have diverged concordantly.
Moth hearing and sound communication
TLDR
Recent findings on moth sound communication reveal that close-range (~ a few cm) communication with low-intensity ultrasounds “whispered” by males during courtship is not uncommon, contrary to the general notion of moths predominantly being silent.
A FISH-based chromosome map for the European corn borer yields insights into ancient chromosomal fusions in the silkworm
TLDR
The boundaries between predicted ancient fusions involving B. mori chromosomes 11, 23 and 24 are identified and a significant difference in the lengths of the candidate regions where no functional genes were observed may reflect the evolutionary time after fusion events.
Ultrasonic courtship song of the yellow peach moth, Conogethes punctiferalis (Lepidoptera: Crambidae)
TLDR
It is reported that males of the yellow peach moth Conogethes punctiferalis sexually communicate with females by emitting loud ultrasound before attempting copulation, indicating that male courtship ultrasound evokes wing-raising as an acceptance behavior from females, which in turn evokes a copulation attempt by a male.
