At high ambient temperatures, honeybees regulate head teriperature by evaporative cooling of regurgitated honeycrop contents. Thoracic temperature is secondarily stabilized as heat flows from thorax to head by means of passive conduction and physiological facilitation resulting from accelerated blood flow. The mechanism permits flight at the extraordinarily high ambient temperature of 46�C without overheating the head and thorax despite prodigious amounts of heat produced as a by-product of… 

Thermoregulation by Individual Honeybees

Indirect evidence suggests that drones have different patterns of endothermy and different mechanisms of heat loss than workers, however, this remains to be explored.

Thermal physiological ecology of Colias butterflies in flight

The balance of heat gain from sunlight versus heat loss from convection and radiation does not appear to change by more than a few percent between the wings-closed basking posture and the variable opening of wings in flight, although several aspects require further study.

How the honey bee regulates its body temperature

Honey bees are able to forage over a 30°C range of air temperature largely because they have behavioural and physiological mechanisms for regulating the temperature of their flight muscles. From very

Evaporative cooling in insects

Soft ticks perform evaporative cooling during blood-feeding

This work describes the first thermoregulatory mechanism in a tick species, Ornithodoros rostratus, and finds that this acarian eliminates big amounts of fluid (urine) through their coxal glands; this fluid quickly spreads over the cuticular surface and its evaporation cools-down the body of the tick.

Thermoregulation in the primitively eusocial paper wasp, Polistes dominulus

It is concluded that P. dominulus individuals demonstrate clear, albeit limited, thermoregulatory capacity.

Temperature regulation of honey bees (Apis mellifera) foraging in the Sonoran desert

Observations of honey bees returning to their hives at high ambient temperatures support the conjecture that honey bees regulate head and thorax temperatures at high Ta by regurgitating droplets of honey stomach contents which are then evaporated.



Thoracic Temperature Stabilization byn Blood Circulation in a Free-Flying Moth

The sphinx moth, Manduca sexta, maintains its thoracic temperature within a degree of 42�C while in free flight over a range of air temperatures from about 17� to 32�C. Tying off the dorsal vessel

Data are consistent with the hypothesis that thoracic temperature is controlled by regulation of heat loss, but a heat budget derived from these data suggests that heat dissipation may not be sufficient to offset the decrease in passive cooling of the thorax at high ambient temperatures.

Heat Transfer in Dragonflies: ‘Fliers’ and ‘Perchers’

Under the authors' experimental conditions the fliers appeared to thermoregulate exclusively via a control of blood circulation, but both showed impressive capacities for heat transfer from thorax to abdomen.

The results indicate that the anatomical counter-current heat exchanger is reduced or eliminated during heat stress by 'chopping' the blood flow into pulses, and the blood pulses are shunted through the petiole alternately by way of a switch mechanism.

Nervous Control of the Heart during Thoracic Temperature Regulation in a Sphinx Moth

Heating the thorax of the sphinx moth, Manduca sexta, evoked pulsations of the heart in the abdomen that were of relatively high rate and amplitude, and traveled from the abdomen into theThoracic temperature often stabilized and abdominal temperature increased sharply.

The Respiratory Currents in the Tracheal System of the Adult Honey-Bee

It is deduced that when an active bee is producing metabolic CO 2 , directed streams of air enter the first thoracic spiracle and the abdominal spiracles and leave via the propodeal spiracles.
