1,3-diglycerides from eggs of Culex pipiens quinquefasciatus and Culex pipiens pipiens
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1973Abstract 1. 1. Ether washings of egg-rafts of the mosquitoes Culex pipiens quinquefasciatus and C. p. pipiens which attracted ovipositing females of these species were prepared. 2. 2. The largest fraction from each of these extracts consisted of a mixture of estrolide 1,3-diglycerides and could not be distinguished by spectrometric or thin ...

3.1. Occurrence and distribution of Culex pipiens complex and Culex torrentium Ace-2 marker molecular results revealed that all samples contained Cx. pipiens, and some points also included Cx. torrentium. Cx. torrentium specimens were identified from only seven collection points (Posof, Galler, Gümüşhane, Ispir Bayburt road, Savsat Artvin, Karakoy, and

Ethanolamine kinase from Culex pipiens fatigans
Archives of Biochemistry and Biophysics, 1981Abstract Ethanolamine kinase was partially purified from the larvae of Culex pipiens fatigans and its properties were studied. The enzyme was separated from choline kinase by acetic acid precipitation at pH 5.0 of a 13,000g supernatant of the larval homogenate.

Pyrethroid resistance in Culex pipiens mosquitoes
Pesticide Biochemistry and Physiology, 2015Mosquitoes within the Culex pipiens complex are widely distributed and important in the transmission of many human diseases. Insecticides, pyrethroids in particular, remain a mainstay for control of these important vectors. In this paper we review what is known about the levels, mechanisms and fitness costs of pyrethroid resistance in Cx.

Hibernaculum Choice in Culex Pipiens
Journal of Medical Entomology, 1972A population of hibernating Culex pipietis was studied during the winters of 1969–1970 and 1970–1971 in an abandoned mine in Illinois. Initial choice of hibernaculum is governed to the extent of 22.7% by light. Distance from the entrance appears unimportant. Texture and dampness of the wall also appear unimportant.

Esterase gene amplification in Culex pipiens
Insect Molecular Biology, 1997In the mosquito Culex pipiens one of the major resistance mechanisms to organophosphorous pesticides (OPs) is increased detoxification of insecticide. This resistance is the consequence of overproduction of two types of esterases, esterases A and B, coded at two loci, Est-3 (A esterase) and Est-2 (B esterase).

Culex pipiens fatigans Wiedemann, a sub-specific variant of Culex pipiens Linnaeus, is worldwide in distribution and is prevalent in the tropics, sub-tropics and warmer temperate climates (Horsfall 1955). C.p. fatigans is known to breed in waters with varying degrees of pollution, primarily soakage pits, household drains, cesspools and puddles. However,

Trehalose ofCulex pipiens fatigans
Experientia, 1975Trehalose was found to occur in the mosquito, Culex pipiens fatigans, to the extent of 23 to 49% of total free sugars in different developmental stages of the insect. Induction of stress to the insects led to significant reduction in the trehalose of larvae and glucose of adults.

Ionic antagonism in mosquito larvae, Culex pipiens
Comparative Biochemistry and Physiology Part A: Physiology, 1975Abstract 1. The toxicities of solutions containing single salts at a concentration of 800 mOsm, to fourth instar Culex pipiens were determined, yielding the toxicity sequence K + , Na + > Ca 2+ , Mg 2+ . 2. The toxicities of mixtures of the chlorides of these salts revealed ion antagonism between Na + and Ca 2+ , Na + and Mg 2+ , and Ca ...
