Quality over quantity: unraveling the contributions to cytoplasmic incompatibility caused by two coinfecting Cardinium symbionts

M. R. Doremus, C. M. Stouthamer, S. E. Kelly, S. Schmitz-Esser and M. S. Hunter,  Heredity,  2022.
Cytoplasmic incompatibility (CI) is a common form of reproductive sabotage caused by maternally inherited bacterial symbionts of arthropods. CI is a two-step manipulation: first, the symbiont modifies sperm in male hosts which results in the death of fertilized, uninfected ...

Recently introduced Wolbachia reduces bacterial species richness and reshapes bacterial community structure in Nilaparvata lugens

T.-P. Li, C.-Y. Zhou, J.-T. Gong, Z. Xi and X.-Y. Hong,  Pest Management Science,  2022.
BACKGROUND Wolbachia has been developed as an effective tool to suppress insect pests and arbovirus transmission. Recently, the brown planthopper Nilaparvata lugens, a serious agricultural pest, has been successfully transinfected with Wolbachia strain wStri from Laodelphax ...

Wolbachia reduces virus infection in a natural population of Drosophila

R. Cogni, S. D. Ding, A. C. Pimentel, J. P. Day and F. M. Jiggins,  Communications Biology,  4:1327. 2021.
Wolbachia is a maternally transmitted bacterial symbiont that is estimated to infect approximately half of arthropod species. In the laboratory it can increase the resistance of insects to viral infection, but its effect on viruses in nature is unknown. Here we report that in a ...

Microsporidia MB is found predominantly associated with Anopheles gambiae s.s and Anopheles coluzzii in Ghana

J. Akorli, E. A. Akorli, S. N. A. Tetteh, G. K. Amlalo, M. Opoku, R. Pwalia, M. Adimazoya, D. Atibilla, S. Pi-Bansa, J. Chabi and S. K. Dadzie,  Scientific Reports,  11:5. 2021.
A vertically transmitted microsporidian, Microsporidia MB, with the ability to disrupt Plasmodium development was reported in Anopheles arabiensis from Kenya, East Africa. To demonstrate its range of incidence, archived DNA samples from 7575 Anopheles mosquitoes collected from ...

Breakthrough in non-GMO malaria control

C. Robinson and J. Matthews,  GM Watch,  2021.
A just-published study carried out in a high-security lab claims to show that a CRISPR gene drive (a way of forcing a heritable genetic modification through a whole species or population) can crash populations of malaria-spreading mosquitoes. But why crash mosquito populations ...

Horizontal Transmission of the Symbiont Microsporidia MB in Anopheles arabiensis

G. Nattoh, T. Maina, E. E. Makhulu, L. Mbaisi, E. Mararo, F. G. Otieno, T. Bukhari, T. O. Onchuru, E. Teal, J. Paredes, J. L. Bargul, D. M. Mburu, E. A. Onyango, G. Magoma, S. P. Sinkins and J. K. Herren,  Frontiers in Microbiology,  12. 2021.
The recently discovered Anopheles symbiont, Microsporidia MB, has a strong malaria transmission-blocking phenotype in Anopheles arabiensis, the predominant Anopheles gambiae species complex member in many active transmission areas in eastern Africa. The ability of Microsporidia ...

Microbiome Innovation in Agriculture: Development of Microbial Based Tools for Insect Pest Management

M. Qadri, S. Short, K. Gast, J. Hernandez and A. C.-N. Wong,  Frontiers in Sustainable Food Systems,  4. 2020.
This review emphasizes the potential and use of microbes in sustainable insect pest management. We first review the diverse insect traits shaped by insect-microbe associations that span nutrition, immunity, ecological interactions with natural enemy, insecticide resistance, and ...

Engineered symbionts activate honey bee immunity and limit pathogens

P. Leonard Sean, J. E. Powell, J. Perutka, P. Geng, C. Heckmann Luke, D. Horak Richard, W. Davies Bryan, D. Ellington Andrew, E. Barrick Jeffrey and A. Moran Nancy,  Science,  367:573-576. 2020.
Honey bees are essential pollinators threatened by colony losses linked to the spread of parasites and pathogens. Here, we report a new approach for manipulating bee gene expression and protecting bee health. We engineered a symbiotic bee gut bacterium, Snodgrassella alvi, to ...

Concept and history of genetic control

Scott, M. J. and Benedict, M. Q.,  Genetic Control of Malaria and Dengue,  2:31-54. 2016.
Genetic control of insects is an established method, mainly for insects that are important crop and veterinary pests such as medflies and screwworm. Efforts to use the same technologies against insects of medical importance, especially mosquitoes, have had limited success. The ...
