Evidence for memorized site-fidelity in Anopheles arabiensis
Transactions of the Royal Society of Tropical Medicine and Hygiene, 2001A mark-recapture experiment was carried out in northern Tanzania to determine whether Anopheles arabiensis exhibits memory, by investigating if bloodfed individuals would return to either the location or the host where or on which they had obtained a previous bloodmeal, behaviours termed site-fidelity and host-fidelity respectively.

Host choice by indoor-resting Anopheles arabiensis in Ethiopia
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1997The host preference of indoor resting Anopheles arabiensis has been determined using a direct enzyme-linked immunosorbent assay. A total of 611 specimens, 258 from human dwellings, 179 from mixed dwellings, and 174 from cattle sheds, was examined. The proportion of human blood meals identified was highest from mosquitoes caught in human dwellings (91.5%

Effect of ionising (gamma) radiation on female Anopheles arabiensis
Transactions of The Royal Society of Tropical Medicine and Hygiene, 2017In a mosquito sterile insect technique programme the ideal scenario is to release male mosquitoes only. However, because there are currently no sex separation strategies which guarantee total female elimination, this study investigated the effect of irradiation on physiological and reproductive fitness of females of an Anopheles arabiensis genetic ...

Chromosomal Inversion Polymorphism in Anopheles Gambiae and Anopheles Arabiensis in Tanzania
International Journal of Tropical Insect Science, 1990Chromosomal inversion polymorphism was investigated in samples of Anopheles gambiae sensu lato collected from different localities of Tanzania. An. merus was found monomorphic, while two widespread inversion polymorphisms were recorded in both An. gambiae sensu stricto (2Rb/+ and 2La/+) and An. arabiensis (2Rb/+ and 3Ra/+).

Population Genetic Structure ofAnopheles gambiaeandAnopheles arabiensisin Niger
Journal of Medical Entomology, 2010The increasing usage of long-lasting insecticide-treated nets allows protection of millions of people from malaria infection. Monitoring studies should be planned during any wide-scale malaria control program integrating insecticide-treated materials, to evaluate their effects and effectiveness on epidemiologically relevant parameters. Such operational

Genetic Sexing Systems in Anopheles arabiensis Patton (Diptera: Culicidae)
Journal of Economic Entomology, 1985Irradiation of male Anopheles arabiensis Patton, followed by crossing and selection, produced a stock in which both malathion and dieldrin resistance were linked closely to the male sex. Testis squashes revealed that a translocation had been induced between one of the autosomes and the Y chromosome.

Seasonal variations in indoor resting Anopheles gambiae and Anopheles arabiensis in Kaduna, Nigeria.
Acta tropica, 1985A longitudinal study in a guinea savanna area in Northern Nigeria showed that indoor resting samples consisted almost entirely of An. gambiae in the wet season, characterized by relatively lower temperature and higher relative humidity, whereas An.

Malathion carboxylesterase enzymes in Anopheles arabiensis from Sudan
Pesticide Biochemistry and Physiology, 1985Abstract Malathion resistance in Anopheles arabiensis from Sudan is monofactorially inherited and is expressed in the adults but not in the larvae. The resistance is suppressed by the esterase synergist, triphenylphosphate. Semipurification of the soluble esterase enzymes by Sephadex G-25 and Sephacryl S-200 gel filtration revealed no difference ...

Biochemical studies on malathion resistance in Anopheles arabiensis from Sudan
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1983The change from larval to adult mosquito control in the Gezira area of Sudan resulted in a decrease in the prevalence of malaria in this region. House spraying with malathion began in 1975 and resistance to this compound was first detected in 1978. Laboratory tests showed that adult Anopheles arabiensis Patton were resistant to malathion and phenthoate
