The recently discovered Anopheles symbiont, Microsporidia MB, has a strong malaria transmission-blocking phenotype in arabiensis, the predominant gambiae species complex member many active transmission areas eastern Africa. ability of MB to block Plasmodium together with vertical and avirulence makes it candidate for development symbiont-based blocking strategy. We investigate characteristics efficiencies between An. arabiensis mosquitoes. show that is not transmitted larvae but effectively...
Anopheles coluzzii is a primary vector of malaria found in West and Central Africa, but its presence has hitherto never been documented Kenya. A thorough understanding bionomics important as it enables the implementation targeted effective control interventions. Malaria surveillance efforts country have tended to focus on historically known vectors. The current study sought determine taxonomic status samples collected from five different epidemiological zones Kenya well describe population...
Insecticide-based malaria vector-control interventions have been economically important in reducing prevalence. However, insecticide resistance now threatens the continued efficacy of insecticides vector control. Monitoring mosquito populations is needed to guide implementation effective management (IRM) strategies. Thus study assessed levels and intensity Anopheles gambiae (sensu lato) five epidemiological zones Kenya, which are subjected different control interventions. (s.l.) larvae were...
Previously, we reported an interesting relationship between virulence and repellency of different isolates the fungus Metarhizium anisopliae towards termite Macrotermes michaelseni: higher a given isolate, greater its repellency. In present study, compared volatile profiles two isolates, one that was more virulent (and repellent) less to termite. The prominent components blends were characterized by gas chromatography-mass spectrometry authenticated chromatography co-injections with...
Larval stages of Frankliniella occidentalis are known to be refractory fungal infection compared with the adult stage. The objective this study was identify promising isolate(s) for control larval F. occidentalis.Ten isolates Metarhizium anisopliae and eight Beauveria bassiana were screened virulence against second-instar larvae occidentalis. Conidial production genetic polymorphism also investigated. ICIPE 7, 20, 69 665 had shortest LT(50) values 8.0-8.9 days. 69, 7 20 lowest LC(50) 1.1 ×...

Abstract UV resistance of bacteria isolated from the marine cyanobacterium Moorea producens has not been observed previously, findings which highlight how unsafe germicidal irradiation for sterilization air, food, and water could be. Further, Bacillus licheniformis is being first time. This study focused on M. collected off Kenyan coast at Shimoni, Wasini, Kilifi, Mida. irradiance isolates (302 nm, 70 W/m 2 , 0–1 hr) established B. as most resistant strain, with following order taxon...
<title>Abstract</title> Background Insecticide resistance in disease vectors poses a significant threat to the control of transmission globally. In Anopheles mosquitoes, has jeopardized gains made malaria and led resurgence cases. Although <italic>Anopheles arabiensis</italic> is major vector, little known about its genetic diversity insecticide mechanisms across geographical space. There an urgent need incorporate genomics monitoring allow preemptive detection adaptive alleles. Methods We...
