“…Based on this approach, and or the combined PCRblot technique developed by the same research group, it was confirmed: (a) that tsetse fly species harbor multiple cytoplasmic strains, (b) the presence of Wolbachia gene insertions onto tsetse host chromosomes and (c) the presence of low-titer infections (Schneider et al, 2013). …”

Tsetse flies (Diptera: Glossinidae) are the sole vectors of African trypanosomes, the causative agent of sleeping sickness in human and nagana in animals. Like most eukaryotic organisms, Glossina species have established symbiotic associations with bacteria. Three main symbiotic bacteria have been found in tsetse flies: Wigglesworthia glossinidia, an obligate symbiotic bacterium, the secondary endosymbiont Sodalis glossinidius and the reproductive symbiont Wolbachia pipientis. In the present review, we discuss recent studies on the detection and characterization of Wolbachia infections in Glossina species, the horizontal transfer of Wolbachia genes to tsetse chromosomes, the ability of this symbiont to induce cytoplasmic incompatibility in Glossina morsitans morsitans and also how new environment-friendly tools for disease control could be developed by harnessing Wolbachia symbiosis.

“…Based on standard PCR assays, Wolbachia can be detected in G. m. morsitans, G. m. centralis and G. austeni populations, but not G. tachinoides . Additionally, low density Wolbachia infections are reported in several species and populations, including G. fuscipes and G. morsitans subspecies (Alam et al, 2012; Schneider et al, 2013). In field G. m. morsitans , Wolbachia infection prevalence ranges from 10 to 100% depending on their resident habitats (Doudoumis et al, 2012).…”

Tsetse flies are the primary vectors of African trypanosomes, which cause Human and Animal African trypanosomiasis in 36 countries in sub-Saharan Africa. These flies have also established symbiotic associations with bacterial and viral microorganisms. Laboratory-reared tsetse flies harbor up to four vertically transmitted organisms—obligate Wigglesworthia, commensal Sodalis, parasitic Wolbachia and Salivary Gland Hypertrophy Virus (SGHV). Field-captured tsetse can harbor these symbionts as well as environmentally acquired commensal bacteria. This microbial community influences several aspects of tsetse's physiology, including nutrition, fecundity and vector competence. This review provides a detailed description of tsetse's microbiome, and describes the physiology underlying host-microbe, and microbe-microbe, interactions that occur in this fly.

“…Although the presence of Wolbachia has been reported in a limited number of tsetse flies samples (Cheng et al, 2000; O’Neill et al, 1993), a thorough investigation for the presence of this symbiont, particularly in natural populations, as well the genotyping of these infections was lacking. One of the specific objectives of this CRP was to study the prevalence, genotyping and phylogenetic analysis of Wolbachia infections in both laboratory and natural populations of Glossina species including the investigation of the potential reproductive effects this infection may have in tsetse flies (see Doudoumis et al 2013; Wang et al 2013, Schneider et al 2013; (Alam et al, 2012; Doudoumis et al, 2012). …”

Tsetse flies (Diptera: Glossinidae) are the cyclical vectors of the trypanosomes, which cause human African trypanosomosis (HAT) or sleeping sickness in humans and African animal trypanosomosis (AAT) or nagana in animals. Due to the lack of effective vaccines and inexpensive drugs for HAT, and the development of resistance of the trypanosomes against the available trypanocidal drugs, vector control remains the most efficient strategy for sustainable management of these diseases. Among the control methods used for tsetse flies, Sterile Insect Technique (SIT), in the frame of area-wide integrated pest management (AW-IPM), represents an effective tactic to suppress and/or eradicate tsetse flies. One constraint in implementing SIT is the mass production of target species. Tsetse flies harbor obligate bacterial symbionts and salivary gland hypertrophy virus which modulate the fecundity of the infected flies. In support of the future expansion of the SIT for tsetse fly control, the Joint FAO/IAEA Programme of Nuclear Techniques in Food and Agriculture implemented a six year Coordinated Research Project (CRP) entitled “Improving SIT for Tsetse Flies through Research on their Symbionts and Pathogens”. The consortium focused on the prevalence and the interaction between the bacterial symbionts and the virus, the development of strategies to manage virus infections in tsetse colonies, the use of entomopathogenic fungi to control tsetse flies in combination with SIT, and the development of symbiont-based strategies to control tsetse flies and trypanosomosis. The results of the CRP and the solutions envisaged to alleviate the constraints of the mass rearing of tsetse flies for SIT are presented in this special issue.
