Anopheles arabiensis
Anopheles arabiensis is a zoophilic species of mosquito and a vector of disease endemic to Africa.
Genome
Polytene chromosomes have a high degree of gene polymorphism due to paracentric inversions. This is also unusually high for the genus. There is a well studied adaptive inversion. Kirkpatrick and Barrett 2015 and Sharakhov et al. 2006 find an inversion providing A. arabiensis with some of its adaptation to arid environments. They also find this inversion has been introgressed across more widely in the genus, providing similar adaptive benefit.Symbionts
Not thought to naturally serve as a host of Wolbachia until Baldini et al. 2018 showed to the contrary.Hosts
Hosts include Bos taurus. A. arabiensis is especially known as a zoophilic haematophage.Parasites
Not a vector of Plasmodium berghei.Range
The distribution is Afrotropical. There was a brief invasion into Brazil in 1930 but this was quickly eradicated. The investigations regarding the ecology of A. arabiensis by Gwitira et al. 2018, Ageep et al. 2009 and Fuller et al. 2012a help to model the distribution of various avian malaria pathogens.Locally A. arabiensis is especially known as an exophage and exophile. Its movements through the local ecology are not sufficiently studied Debebe et al. 2018 is one of the few investigations in this question.
Control
Cyhalothrins and DDT are commonly used. Mnzava et al. 1995 finds differential repellent effects between λc and DDT in the protection of cattle, partly due to DDT's excitorepellency.Sterile insect technique shows promise in A. arabiensis. Irradiation in SIT is not simple however and dosage is a touchy variable. Sterile males are also injured more generally by the process and thus are less competitive. Helinski and Knols 2008 provide dosage information from their experiments with A. arabiensis which is needed to perform SIT successfully.
This process requires separation of the sexes which historically has been done manually, greatly limiting throughput. Mashatola et al. 2018 reviews progress in automation, selective insecticide feeding, and genetic sexing strains.
SIT may also be achieved by genetic modification, disabling the reproductive process. Catteruccia et al. 2005 produced such an A. arabiensis strain and demonstrates more generally that genetic SIT is tractable in this species.
it has only recently been found that adult mosquitoes are vulnerable to entomopathogenic fungi. This has provoked interest in studying this kind of control, especially Kikankie et al. 2010's success with Beauveria bassiana.
Understanding of A. arabiensis movements through the landscape will need to improve to aid control efforts. Debebe et al. 2018 is one of very few contributions to this area.
