“…These multilobed sensilla slightly resemble the branched humidity detectors found on the antennae of some Coleoptera (Roth and Willis 1951). It is possible that they have the same function in E. furcellata because it is known that all heteropterans require high humidity.…”

Usha Rani, P. 2009. Sensillary morphology on the rostral apex and their possible role in prey location behaviour of the carnivorous stinkbug, Eocanthecona furcellata (Wolff) (Heteroptera: Pentatomidae). -Acta Zoologica (Stockholm) 90 : 246-253Eocanthecona furcellata (Wolff ), the carnivorous heteropteran, demonstrates interesting feeding mechanisms that suggest the involvement of the antennal and labial tip sensilla. This study was conducted to identify the morphology of various sensilla present on the labial tip of this insect using scanning electron microscopy. Four morphologically different types of trichoid sensilla comprise the largest and most numerous sensilla and occur throughout the surface of the labial tip. Three new and unique types of sensilla were discovered. Long hairs with profusely branched shafts are present at the entrance of the rostral groove. An oval-shaped peg surrounded by sensory hairs with branched shafts and a short, stout peg encircled by a group of long hair-like sensilla was found among the sensilla population of two lobes. The morphology of the new sensilla is given and possible functions of individual receptors are suggested on morphological grounds.

“…The answer seems to lie in the fact that the results obtained depend mainly on two factors: a) the physiological state (water balance, gravidity) of the mosquitoes, as shown in the present investigation. Other arthropods were also shown, by various investigators, to give a reversed wet reaction, due to a change in their water balance (DE MEILLON, 1937;GUNN 8,: COSWAY, 1938;BENTLEY, 1944;LEES, 1948;WILLIS & ROTH, 1950;ROTH & WILLIS, 1951b;PERTTUNEN, 1955;SMEREKA & HODSON, 1959). b) the technique used in the testing procedure.…”

“…In general, orientation of an insect involves klinokinesis, hygrokinesis, orthokinesis and klinotaxis (FRAENKEL & GUNN, 1940). In some insects studied the response to humidity was due only to kinetic-type reaction (KENNEDY, 1937;BENTLEY, 1944;ROTH & WILLIS, 1951b). A taxis-type reaction was observed by THOMSON (1938), whereas a combination of both types of reactions was exhibited by other insects (LEES, 1943(LEES, , 1948PlELOU & GUNN, 1940;BURSELL & EXlFER, 1950;SMEREKA & HODSON, 1959).…”

A method is described by which the effect of a wet surface and the air close to it (up to a height of 2 cm) on female Aedes aegypti (L.) could be determined. The insects were placed in a petri dish, under controlled conditions of ambient temperature and humidity. The bottom of the petri dish was lined with two semicircular filter papers, one being kept dry and the other wet. The intensity of the response was determined as the mean excess percentage of position records on the dry and wet sides. Female mosquitoes avoided very strongly a wet surface and moderately the air close to it. Mosquitoes did not feed on a human arm as long as the skin was kept wet. Desiccated mosquitoes (water loss of 5.6% or higher of their body weight) were strongly attracted to a wet surface and moderately to the air close to it. The higher the desiccation, the stronger was the attraction. Gravid mosquitoes moderately avoided a wet surface, but gave no reaction to the air close to it. There is some evidence that gravid mosquitoes must get into a “laying state” before attraction to a wet surface occurs. The higher the ambient R.H., the stronger the avoidance of a wet surface and of the air close to it. High and low ambient temperatures (35 and 18° C) gave a weaker dry response than a medium temperature (28° C). The causes of the contradictory results obtained by various investigators reporting the response of mosquitoes to moisture are discussed. These differences are most probably due to differences in the technique used and in the physiological state of the mosquitoes. The avoiding reaction from a wet region is due to a taxis‐type, not to a kinesis‐type, reaction. Resume RÉACTION DES MOUSTIQUES A LA MOITEUR ET A LA FORTE HUMIDITÉ La description d'une méthode déterminant l'effet d'une surface moite et de l'air dans sa proximité (jusqu'à une distance de 2 cm) sur la femelle d'Aedes aegypti est présentée. Les insectes sont introduits dans une boǐte de petri sous des conditions contrǒlées de température et d'humidité ambiantes. Deux demi‐ronds de papier filtre sont placés dans le fond de la boǐte; l'un sec et l'autre moite. L'intensité de la réaction est déterminée par la moyenne du pourcentage de l'excédent enregistrant les positions respectives sur les cǒtés sec et moite. Les moustiques femelles évitent fortement une surface moite, et modérément l'air dans sa proximité. Les moustiques ne se nourrissent pas sur un bras humain préalablement humecté tant que la peau reste moite. Les moustiques desséchés (perte d'eau 5.6% ou plus dú poids du corps) sont fortement attirés par une surface moite, et modérément par l'air dans sa proximité; l'attraction augmentent avec la desiccation. Les moustiques gravides évitent modérément une surface moite, mais ne réagissent pas à l'air dans sa proximité. Il existe des indications que les moustiques gravides doivent atteindre un “état de ponte”, avant que la surface moite ne les attire. L'évitement d'une surface moite et de l'air dans sa proximité augmente avec l'...

“…It is well known that many insects,when offered choice in a gradient of humidity, select a dry environment when hydrated and a wet one after periods of desiccation (Begg and Hogben, 1946;Bentley, 19~4;Haufe, 196~b;Willis, 1951a, Willis andRoth, 1950). This reaction is reversible in the majority of insects subjected to this type of experiment and it is probably universal or nearly so among insects that are sensitive to atmospheric humidity.…”
