The Hsf1-sHsp cascade has pan-antiviral activity in mosquito cells by Jieqiong Qu, Michelle Schinkel, Lisa Chiggiato, Samara Rosendo Machado, Gijs J. Overheul, Pascal Miesen, Ronald P. van Rij

“…This Hsf1-sHsp cascade acts as an early response against chikungunya virus infection and shows pan-antiviral activity against chikungunya, Sindbis, and dengue virus as well as the insect-specific Agua Salud alphavirus in Ae. aegypti cells and against chikungunya virus and O’nyong-nyong virus in Aedes albopictus and Anopheles gambiae cells, respectively. Our comprehensive in vitro data suggest that Hsf1 could serve as a promising target for the development of novel intervention strategies to limit arbovirus transmission by mosquitoes.…”

Gene drive-based population suppression in the malaria vector Anopheles stephensi by Xuejiao Xu, Jingheng Chen, You Wang, Yiran Liu, Yongjie Zhang, Jie Yang, Xiaozhen Yang, Bin Chen, Zhengbo He, Jackson Champer

“…Both male and female drive heterozygotes show only moderate drive conversion, indicating that the nanos promoter has lower activity in A. stephensi than in Anopheles gambiae. By amplicon sequencing, we detect a very low level of resistance allele formation. …”

Variation in Malaria Transmission Dynamics in Three Different Sites in Western Kenya by S. S. Imbahale, W. R. Mukabana, B. Orindi, A. K. Githeko, W. Takken

“…Negative binomial and Poisson generalized additive models were used to examine the risk of being infected, as well as the association with the weather variables. Anopheles gambiae s.s. was most abundant in Lunyerere, An. arabiensis in Nyalenda and An. funestus in Fort Ternan. …”

Insecticide resistant Anopheles from Ethiopia but not Burkina Faso show a microbiota composition shift upon insecticide exposure by Netsanet Worku, Antoine Sanou, Juliane Hartke, Marion Morris, Fatoumata Cissé, Salimata Ouédraogo, Madou Tapsoba, Nicola Vallon, Tewodros Debebe Akilu, Ligabaw Worku, Moussa Wamdaogo Guelbeogo, Victoria A. Ingham

“…Methods Here, we compare the microbiota composition of insecticide-resistant populations of Anopheles gambiae, An. coluzzii and An. arabiensis from Burkina Faso, and in the latter case additionally from Ethiopia, to insecticide-susceptible populations. …”

Analysis of somatic piRNAs in the malaria mosquito Anopheles coluzzii reveals atypical classes of genic small RNAs by Sergei Funikov, Alexander Rezvykh, Natalia Akulenko, Jiangtao Liang, Igor V. Sharakhov, Alla Kalmykova

“…We also identified atypical genic small RNAs in Anopheles gambiae somatic tissues, which further validates the noncanonical mechanism of their production. …”

Culex quinquefasciatus: status as a threat to island avifauna and options for genetic control by Tim Harvey-Samuel, Thomas Ant, Jolene Sutton, Chris N. Niebuhr, Samoa Asigau, Patricia Parker, Steven Sinkins, Luke Alphey

“…One alternative approach would be the utilisation of genetic control methods, several of which have been successfully developed in other mosquitos such as Aedes aegypti and the malaria vector Anopheles gambiae. However, the development of similar tools for Cx. quinquefasciatus has been comparatively limited. …”
