“…Wing-beat frequency increases with Tb in a variety of Lepidoptera, Diptera, and Hymenoptera, but may plateau above 30°-35°C (208). In the blowfly Phaenicia sericata, flight speed, wing-beat frequency, and 02 consumption increase slowly with Tb from 15°-35°C (236,237).…”

“…In small insects, such as dipterans, that do not generate enough metabolic heat to regulate body temperature (Stevenson 1985), wing-beat frequency increases linearly with ambient temperature (Chadwick 1939;Reed et al 1942;Yurkiewicz and Smyth 1966a;Hargrove 1980;Curtsinger and Laurie-Ahlberg 1981;Unwin and Corbet 1984). The mean lift is directly proportional to the square of wing-beat frequency (Ellington 1984c) so, as temperature decreases, the lift produced by an insect will also decrease.…”

“…The mean lift is directly proportional to the square of wing-beat frequency (Ellington 1984c) so, as temperature decreases, the lift produced by an insect will also decrease. In addition, ambient temperature affects the energetic efficiency of insect flight, because this is determined by the match between the current wing-beat frequency and the mechanical resonance frequency of the wing/flight muscle system (Greenewalt 1960;Machin et al 1962;Yurkiewicz and Smyth 1966b;Yurkiewicz 1968).…”

LATITUDINAL VARIATION OF WING:THORAX SIZE RATIO AND WING-ASPECT RATIO INDROSOPHILA MELANOGASTER

In dipterans, the wing-beat frequency, and, hence, the lift generated, increases linearly with ambient temperature. If flight performance is an important target of natural selection, higher wing:thorax size ratio and wing-aspect ratio should be favored at low temperatures because they increase the lift for a given body weight. We investigated this hypothesis by examining wing: thorax size ratio and wing-aspect ratio in Drosophila melanogaster collected from wild populations along a latitudinal gradient and in their descendants reared under standard laboratory conditions. In a subset of lines, we also studied the phenotypic plasticity of these traits in response to temperature. To examine whether the latitudinal trends in wing:thorax size ratio and wing-aspect ratio could have resulted from a correlated response to latitudinal selection on wing area, we investigated the correlated responses of these characters in lines artificially selected for wing area. In both the geographic and the artificially selected lines, wing:thorax size ratio and wing-aspect ratio decreased in response to increasing temperature during development. Phenotypic plasticity for either trait did not vary among latitudinal lines or selective regimes. Wing:thorax size ratio and wing-aspect ratio increased significantly with latitude in field-collected flies. The cline in wing:thorax size ratio had a genetic component, but the cline in wing-aspect ratio did not. Artificial selection for increased wing area led to a statistically insignificant correlated increase in wing:thorax size ratio and a decrease in wing-aspect ratio. Our observations are consistent with the hypotheses that high wing-thorax size ratio and wing aspect ratio are per se selectively advantageous at low temperatures.

“…1 and 2). The rate at flight initiation rose by 4.2 Hz/OC between 20 and 32OC, which compares with 5.2 Hz/OC forDrosophila repleta (Chadwick, 1939) and 4.1 Hz/OC for Phaenicia sericata (Yurkiewicz & Smyth, 1966).…”

“…In view of these results and the fact that in insects with myogenic flight rhythms wingbeat frequency and fuel consumption are both positively correlated with temperature (Yurkiewicz & Smyth, 1966) it would be expected that, in tsetse, increased temperatures should result also in a more rapid decline in wingbeat frequency and a decrease in flight duration. These matters have been studied using the flight mill decribed by Cullis & Hargrove (1 972), whereby wingbeat frequency can be recorded automatically.…”

ABSTRACT. The wingbeat frequency at flight initiation in mature male G.morsitans West, rose approximately linearly from 213 Hz at 20°C to 263 Hz at 32°C. An increase of temperature to 36°C produced no further effect. The time course of frequency changes was affected in a complex manner by temperature, due probably to the interaction of a number of physico‐chemical and behavioural processes with different temperature dependencies. Higher temperatures caused a more rapid overall decline in wingbeat frequency, consistent with the greater demand on the limited reserve of the only important flight substrate, proline. At 20°C, a considerable proportion of tsetse were relatively inactive, whilst a small proportion flew for longer than at any other temperature. At intermediate temperatures both extremes in flight duration decreased, but at 36°C 80% of tsetse flew for less than 90s. These observations can be explained on the basis of the interaction between the tendency of tsetse to be inactive at extremes of temperature, and the more rapid oxidation of reserves at higher temperatures.
