Introducing a turbulence...

...Nicolas Durand; Paleo Aguilar; Elodie Demondion; Thomas Bourgeois; Françoise Bozzolan; Stéphane Debernard ABSTRACT In the moth Agrotis ipsilon , the behavioral response of males to the female-emitted sex pheromone increases throughout adult life and following a prior exposure to sex pheromone...

...Kalyanasundaram Parthasarathy; M. A. Willis ABSTRACT The hawkmoth Manduca sexta is nocturnally active, beginning its flight activity at sunset, and executing rapid controlled maneuvers to search for food and mates in dim light conditions. The visual system of this moth has been shown to trade off...

...Emanuel C. Mora; Ariadna Cobo-Cuan; Frank Macías-Escrivá; Martha Pérez; Manuela Nowotny; Manfred Kössl SUMMARY The mechanical tuning of the ear in the moth Empyreuma pugione was investigated by distortion-product otoacoustic emissions (DPOAE) and laser Doppler vibrometry (LDV). DPOAE audiograms...

... with studying nocturnal, volant animals that use ultrasound and engage in battles that frequently last a fraction of a second. We overcame these challenges using a robust field methodology that included multiple infrared cameras calibrated for three-dimensional reconstruction of bat and moth flight trajectories...

...Aaron J. Corcoran; Jesse R. Barber; Nickolay I. Hristov; William E. Conner SUMMARY The tiger moth Bertholdia trigona is the only animal in nature known to defend itself by jamming the sonar of its predators – bats. In this study we analyzed the three-dimensional flight paths and echolocation...

...Romina B. Barrozo; Christophe Gadenne; Sylvia Anton SUMMARY In the moth, Agrotis ipsilon , newly mated males cease to be attracted to the female-produced sex pheromone, preventing them from re-mating until the next night, by which time they would have refilled their reproductive glands...

...Romina B. Barrozo; David Jarriault; Xenia Simeone; Cyril Gaertner; Christophe Gadenne; Sylvia Anton SUMMARY In the male moth, Agrotis ipsilon , mating induces a transient inhibition of behavioural and central nervous responses to sex pheromone. Newly mated males are not attracted to sex pheromone...

...David Jarriault; Christophe Gadenne; Jean-Pierre Rospars; Sylvia Anton SUMMARY To find a mating partner, moths rely on pheromone communication. Released in very low amounts, female sex pheromones are used by males to identify and localize females. Depending on the physiological state (i.e. age...

...Christian Flecke; Jan Dolzer; Steffi Krannich; Monika Stengl SUMMARY Pheromone-dependent mate search is under strict circadian control in different moth species. But it remains unknown whether daytime-dependent changes in pheromone sensitivity already occur at the periphery in male moths. Because...

... that the superposition eyes of moths and skippers often deviate severely from the expected ideal case. Part of the deviation has been attributed to diffraction at the single facet lens, which was taken to be an essential limit to spatial resolution, because light traveling through different facet lenses was assumed...

...H. Arthur Woods; Roger T. Bonnecaze; Brandy Zrubek SUMMARY Insect eggs must obtain oxygen across the eggshell to support embryonic development. Because eggs are small, obtaining enough oxygen would seem trivial. Recent work, however, has shown that eggs of a moth, Manduca sexta , are oxygen limited...

... whether survival, development time and metabolism of eggs of a moth, Manduca sexta , were sensitive to experimentally imposed variation in atmospheric oxygen availability(5–50 kPa; normoxia at sea level is 21 kPa) across a range of biologically realistic temperatures. Temperature–oxygen interactions were...

Two example species, Drepana arcuata and Watsonalla uncinula , were examined. The abdominal ears of drepanids...
