Nutritional requirements of Aedes aegypti L.

Journal of Insect Physiology, 1957
Abstract Larvae of Aedes aegypti can be reared on a chemically defined diet consisting of glucose, salt mixture, lipids, RNA, 17 amino acids, glutathione, and 12 vitamins, provided the osmotic pressure of the diet does not exceed Δ0·4°C. l -Valine, l -leucine, l -isoleucine, l -phenylalanine, l -histidine, l -arginine, l -tryptophane, l ...

Description of the ovarian microbiota of Aedes aegypti (L) Rockefeller strain

Acta Tropica, 2021
Aedes aegypti is one of the vectors responsible for transmitting the viruses that cause dengue, Zika and chikungunya in the human population. Mosquitoes have bacterial communities in different organs, mainly in the midgut, but to a lesser extent in their reproductive organs, such as the ovaries, where replication and vertical transmission is decisive ...

Chemosterilization of Aedes aegypti (L.) by Pupal Treatment

Nature, 1966
THE concept of insect control through the liberation of sterile males1 proved successful in the eradication of the screw-worm fly (Cochliomyia hominivorax) from the south-eastern United States2. Following this success, in which sterility was induced by γ-irradiation, interest was taken in the possibility of inducing sexual sterility by chemical means3.

The spectral sensitivity of Aedes aegypti (L.) at oviposition

Bulletin of Entomological Research, 1971
The spectral sensitivity of gravid female Aedes aegypti (L.) was investigated in the laboratory using their responses to oviposition sites illuminated by light of defined intensity and spectral composition. An inverse relationship between the illumination of an oviposition site and its selection for egg-deposition enabled the sensitivity of the ...

Oviposition of Aedes aegypti L. on a Dry Surface and Hygroreceptors

Nature, 1967
IT is known that the mosquitoes Culex and Anopheles lay their eggs on water and that Aedes lays its eggs on wet surfaces. If a wet surface is absent, Aedes will not lay eggs1,2 nor will Culex2. In Anopheles, however, some laying can be obtained on a dry surface2,3. When gravid females of A.

Some properties of oral secretion from Aedes aegypti (L.)

Experimental Parasitology, 1966
Abstract Oral secretion was collected from Aedes aegypti mosquitoes. Intradermal injections of oral secretion given to sensitized individuals caused skin reactions similar to those provoked by A. aegypti bites. Experimental animals were sensitized by injections of oral secretion, as shown by their subsequent reactions to test bites from A ...

Host feeding responses of Aedes aegypti (L.) exposed to deltamethrin

Journal of Vector Ecology, 2011
Escape responses of mated and unmated nulliparous Aedes aegypti mosquitoes were compared using three different concentrations of deltamethrin in the presence or absence of a live animal host using an excito-repellency (ER) test system. Both insecticide contact (excitation) and non-contact (repellency) test configurations were compared.

The esterase patterns in the ovaries and the embryonated eggs of "Aedes aegypti" L.

Acta tropica, 1975
The esterases of Aedes aegypti were studied in the ovary before and during a gonotrophic cycle and also in fully embryonated eggs by means of disc electrophoresis. During oogenesis no significacant changes can be observed besides a marked increase in the total esterase activity. A different esterase pattern is found in eggs after embryogenesis.

Antimetabolites in the nutrition of Aedes aegypti L. larvae. Pyridoxine antagonists

Comparative Biochemistry and Physiology, 1963
Abstract 1. 1. The effect of graded doses of three pyridoxine antagonists on A. aegypti larvae, grown on a chemically defined diet containing minimum pyridoxine, was tested. 2. 2. The antagonism of 4-deoxypyridoxine was reversible by pyridoxine, but not competitively.

Reproductive Behavior of Aedes Aegypti (L.) Sublethally Exposed To Ddt

Journal of Medical Entomology, 1967
A laboratory population of Aedes aegypti was either not affected by or was able to adjust to sublethal exposures of DDT standardized at a 2-hour exposure of 0.1 ppm. The behavior of 13 generations exposed to DDT was observed and analyzed.
