Background Dengue (DENV), chikungunya (CHIKV) and Zika virus (ZIKV), are mosquito-borne viruses of medical importance in most tropical and subtropical regions. Vector control, primarily through insecticides, remains the primary method to prevent their transmission. Here, we evaluated insecticide resistance profiles and identified important underlying resistance mechanisms in populations of Aedes aegypti and Ae. albopictus from six different regions in Cameroon to pesticides commonly used during military and civilian public health vector control operations. Methods Aedes mosquitoes were sampled as larvae or pupae between August 2020 and July 2021 in six locations across Cameroon and reared until the next generation, G1. Ae. aegypti and Ae. albopictus adults from G1 were tested following World Health Organization (WHO) recommendations and Ae. aegypti G0 adults screened with real time melting curve qPCR analyses to genotype the F1534C, V1016I and V410L Aedes kdr mutations. Piperonyl butoxide (PBO) assays and real time qPCR were carried out from some cytochrome p450 genes known to be involved in metabolic resistance. Statistical analyses were performed using Chi-square test and generalized linear models. Results Loss of susceptibility was observed to all insecticides tested. Mortality rates from tests with 0.25% permethrin varied from 24.27 to 85.89% in Ae. aegypti and from 17.35% to 68.08% in Ae. albopictus. Mortality rates for 0.03% deltamethrin were between 23.30% and 88.20% in Ae. aegypti and between 69.47 and 84.11% in Ae. albopictus. We found a moderate level of resistance against bendiocarb, with mortality rates ranging from 69.31% to 90.26% in Ae. aegypti and from 86.75 to 98.95% in Ae. albopictus. With PBO pre-exposure, we found partial or fully restored susceptibility to pyrethroids and bendiocarb. The genes Cyp9M6F88/87 and Cyp9J10 were overexpressed in Ae. aegypti populations from Douala sites resistant to permethrin and deltamethrin. Cyp6P12 was highly expressed in alphacypermethrin and permethrin resistant Ae. albopictus samples. F1534C and V1016I mutations were detected in A. aegypti mosquitoes and for the first time V410L was reported in Cameroon. Conclusions This study revealed that Ae. aegypti and Ae. albopictus are resistant to multiple insecticide classes with multiple resistance mechanisms implicated. These findings could guide insecticide use to control arbovirus vectors in Cameroon.

Dengue Hemorrhagic Fever (DHF) in Central Java Province is in the second position after East Java-based on mortality rates and Temanggung District is one of the areas in Central Java, which is in high endemic status. The level of dependence of DHF in an area can be influenced by DHF in other adjacent areas. The spread of this disease through mosquito bites from one place to another depends on the presence of the cases and the vector of Aedes sp. This study aimed to identify factors related to the clustering pattern of DHF cases in Temanggung, Central Java. This study used a cross-sectional design and was carried out in the Kandangan Health Center Work Area, Temanggung District. The sample of this study was the houses of all DHF cases in 2020 as many as 60 houses with the research variables: the existence of Aedes sp., vector breeding sites, population density, and time of occurrence. This study uses clustering analysis in the form of the Average Nearest Neighbor (ANN) test with =0.05. The results showed that the factors related to the case-grouping pattern in the Kandangan Health Center Work Area were the presence of Aedes sp., vector breeding sites, high population density, and peak dengue cases that occurred in January and February. The results of this study can be used to determine priority areas in controlling dengue cases in an area.

“…The ancestral form Aaf is not known to have ever occurred outside Africa and today is found in many habitats within Africa, including both forests and urban locations [ 2 , 4 ]. This form is not specialized on human hosts or habitats and may play a less important role in spreading human disease [ 5 , 6 , 7 ], although some populations in West Africa are competent vectors of flaviviruses [ 8 , 9 ] and are found in sympatry with Aaa using human made containers as larval habitats [ 10 , 11 ]. The highly anthropophilic and therefore the most familiar form is Aaa , most likely differentiated from Aaf around 4000–6000 years ago, when the aridification of northern Africa pushed the limit of Aaf further south [ 12 ].…”

Aedes aegypti is a ubiquitous vector of arboviruses mostly in urbanised areas throughout the tropics and subtropics and a growing threat beyond. Control of Ae. aegypti is difficult and costly, and no vaccines are available for most of the viruses it transmits. With practical control solutions our goal, ideally suitable for delivery by householders in affected communities, we reviewed the literature on adult Ae. aegypti biology and behaviour, within and close to the human home, the arena where such interventions must impact. We found that knowledge was vague or important details were missing for multiple events or activities in the mosquito life cycle, such as the duration or location of the many periods when females rest between blood feeding and oviposition. The existing body of literature, though substantial, is not wholly reliable, and evidence for commonly held “facts” range from untraceable to extensive. Source references of some basic information are poor or date back more than 60 years, while other information that today is accepted widely as “fact” is not supported by evidence in the literature. Many topics, e.g., sugar feeding, resting preferences (location and duration), and blood feeding, merit being revisited in new geographical regions and ecological contexts to identify vulnerabilities for exploitation in control.
