Sensitivity of the Noctuid Moth Enargia paleacea Esp. (Lepidoptera, Noctuidae) to Echo-like Stimuli
نویسندگان
چکیده
Among insects, the pulse echolocation capacity has been so far demonstrated only in the group of noctuid moths (Noctuidae) [7]. The probing signals of the noctuid moths are short (25-190 μs) ultrasonic clicks, the main spectral maximums of the signals being located above 30 kHz [4]. Auditory (tympanal) organs of noctuid moths are paired organs located in the thoracic segment. The tympanal organ (TO) contains two receptor cells responding to the tympanal membrane vibration. According to the results of the electrophysiological and behavioral studies, the moths are capable of detecting ultrasound within the frequency range from 10 to more than 100 kHz (1,9, 10].

Noctuidonema dibolia n. sp., an ectoparasite of adults of the noctuid moth Mocis latipes (Guenée) is described. The differentiating characters are a club-shaped body with a subterminal vulva in the female, spicules with a reduced matrix and sheath and closely apposed dorsal and ventral arms in the male, very long stylet and conus, moderately prominent stylet knobs, a bluntly rounded head, and a...
متن کاملDirectional sensitivity of the ears of noctuid moths.
Moths of several families, notably the Noctuidae, Arctiidae and Geometridae, have tympanic organs sensitive to pulsed ultrasound (Eggers, 1919; Haskell & Belton, 1956; Roeder & Treat, 1957). It has long been suspected that moths could hear the cries of approaching bats which prey upon them (White, 1877) and a variety of behavioural responses to natural and artificial acoustic stimuli have been ...
متن کاملThe peripheral auditory characteristics of noctuid moths: information encoding and endogenous noise
The ability of the noctuid A1 cell acoustic receptor to encode biologically relevant information from bat echolocation calls is examined. Short-duration stimuli (less than approximately 6 ms) reduce the dynamic resolution of the receptor, making intensity, and hence range, estimates of foraging bats unreliable. This low dynamic range is further reduced by inaccurate encoding of stimulus intensi...

A new species of the New World genus Lespesia, Lespesia melloi SP NOV: (Diptera: Tachinidae), is described from southeastern Brazil. The species is reported here as a parasitoid of Xanthopastis timais (Cramer, 1782) (Lepidoptera: Noctuidae). The caterpillars of this noctuid feed on leaves and bulbs of amaryllis (Amaryllidaceae) in Brazil.

Beach plum, Prunus maritima Marshall, 1785 not Wangenh., 1787 (Rosaceae), currently under development as a potential crop, represents an under-acknowledged host plant for several Lepidoptera that have undergone declines in the northeastern USA. The Coastal Heathland Cutworm, Abagrotis nefascia (Smith, 1908), and the Dune Noctuid, Sympistis riparia (Morrison, 1875), are unrelated species of psam...
