Antennal Responses

Dynamic properties of pheromone plumes are behaviorally important in some moths for inducing upwind flight, but little is known about the time-dependent properties of odor transduction or the mechanisms that limit receptor dynamic sensitivity. We stimulated male antennae of two moth species, Cadra cautella and Spodoptera exigua, with pheromone plumes in a wind tunnel while recording electroantennograms (EAG) and concentration of a surrogate plume (propylene, which mimics a pheromone plume) using a photoionization detector (PID). Turbulent plumes were produced by mechanical baffles, creating broad frequency range dynamic concentration changes at the antennae. Frequency response functions and coherence functions between PID and EAG signals were used to measure the dynamic responses of the two species to pheromone blends and individual components. A single time constant filter fitted the responses of both species, but S. exigua was about three times faster than C. cautella. Responses to individual pheromone components were significantly different in S. exigua but not in C. cautella. We also fitted the data with a simple block-structured nonlinear cascade. This supported the simple filter model but also suggested that the response saturates at an early stage of chemotransduction.

A New Species

A new species of forester moths, Pollanisus hyacinthus sp. nov., is described from Kangaroo Island, South Australia. It is similar to Pollanisus isolatus Tarmann, 2004 and Pollanisus cyanota (Meyrick, 1886) but differs in several external characters and in the genitalia.

Abstract Sex attractants for 3 Sesiidae and 3 Tineidae moth species in West-Kazakhstan and Lithua­nia were discovered by field screening tests of (3Z,13Z)-, (3E,13Z)-and (2E,13Z)-octadeca-dien-1-ols and their acetates as well as of some binary mixtures of these compounds. Total amount of chemicals was 0.3 mg/dispenser. Males of Synanthedon serica were attracted by a 5:5 mixture of 3E,13Z-18:OA c and 2E,13Z-18:OAc, Chamaesphecia bibioniformis by a 9:1 mixture of 3Z,13Z-18:OAc and 3E,13Z-18:OAc, Paranthrene tabaniformis by a 1:9 mixture of 3Z,13Z-18:OH and 3E,13Z-18:OH , Tinea nonimella by a 1:9 mixture of 3E,13Z-18:OH and 2E,13Z-18:OH , Monopis monachella by a 1:9 mixture of 3Z,13Z-18:OH and 2E,13Z -18:OH, and Nemaxera betulinella by a 9:1 mixture of 2E,13Z-18:OAc and the corresponding alcohol. The periods of attraction to the traps were registered for males of S. serica and Ch. bibioniformis and were found to occur at 15 - 18 and 1 5 -17 o'clock, local time, respectively.

Subjective Synonym

We here describe a new clearwing moth species, Aschistophleps ignisquamulata sp. nov., from northern Thailand and Laos. This striking new species differs from all other species of Osminiini in both external appearance and genitalia and displays characteristics that indicate that Pyrophleps Arita & Gorbunov is a junior subjective synonym of Aschistophleps (syn. nov.).
