“…gambiae has implications for species distribution and aquatic habitat colonization. Faster development time in temporary aquatic habitats is a plastic phenotypic trait of major importance that enables a species to reduce its exposure to negative effects such as desiccation (Lee et al ., ; Benedict et al ., ), predation risk (Gimonneau et al ., ), cannibalism (Koenraadt & Takken, ; Muturi et al ., ), pathogens (Ward & Savage, ) and flushing caused by rainfall (Paaijmans et al ., ).…”

New genetic control methods for mosquitoes may reduce vector species without direct effects on other species or the physical environment common with insecticides or drainage. Effects on predators and competitors could, however, be a concern as Anopheles gambiae s.l. is preyed upon in all life stages. We overview the literature and assess the strength of the ecological interactions identified. Most predators identified consume many other insect species and there is no evidence that any species preys exclusively on any anopheline mosquito. There is one predatory species with a specialisation on blood-fed mosquitoes including An. gambiae s.l.. Evarcha culicivora is a jumping spider, known as the vampire spider, found around Lake Victoria. There is no evidence that these salticids require Anopheles mosquitoes and will readily consume blood-fed Culex. Interspecific competition studies focus on other mosquitoes of larval habitats. Many of these take place in artificial cosms and give contrasting results to semi-field studies. This may limit their extrapolation regarding the potential impact of reduced An. gambiae numbers. Previous mosquito control interventions are informative and identify competitive release and niche opportunism; so while the identity and relative abundance of the species present may change, the biomass available to predators may not.

“…Desiccation may positively affect the oviposition habitat selection by mosquitoes during post-draught periods (Duchet et al 2020). However, Benedict et al (2010) noted significant differences in desiccation tolerance between An. arabiensis and An.…”

“…arabiensis had a much-reduced desiccation tolerance compared to that of An. gambiae (Benedict et al 2010). For dealing with desiccation or overcoming it, insects use three recognized physiological mechanisms: (i) enhancement of water storage either in the form of metabolic water (molecules of water obtained directly from catabolism) or in that of bulk water (water molecules obtained from sources other than catabolism) or both, (ii) regulation of water loss through respiration and trans-cuticular transpiration, and (iii) development of tolerance to water loss (Gray and Bradley 2005;Archer et al 2007).…”

A laboratory assessment of desiccation tolerance in larval stages of mosquitoes Anopheles stephensi Liston, 1901 (Diptera: Culicidae) and Culex quinquefasciatus Say, 1823 (Diptera: Culicidae) was carried out using five temperature levels and three levels of exposure duration as explanatory variables. The increase in the duration of exposure to desiccation from 15 min to 60 min was noted to result in a substantial increase in water loss (in mg) in mosquito larvae. Similarly, the increase in temperature levels was observed to cause larval mortality and a substantial decrease in the emergence of adults. Both the temperature and the duration of exposure to desiccation were found to be influential factors in determining survival and subsequent emergence of adults. Desiccation is a primary factor in determining the survival of mosquito larvae, particularly in the conditions where habitat permanence is uncertain, e.g., in temporary pools and containers serving as mosquito larval habitats. The results of the present study provide a glimpse into the effects of desiccation at varied temperatures and exposure durations on the successful emergence of adults in mosquitoes Cx. quinquefasciatus and An. stephensi. Although primary, the obtained results show that desiccation can be a probable way of regulating the development of mosquito larvae in conditions where the permanence of the habitat for mosquito larvae is uncertain. Further studies on desiccation tolerance may be carried out using different mosquito species that are adapted to temporary pools and containers as sources for breeding.

Anopheles gambiae s.l. (Diptera: Culicidae) is responsible for the transmission of the devastating Plasmodium falciparum (Haemosporida: Plasmodiidae) strain of malaria in Africa. This study investigated the relationship between climate and environmental conditions and An. gambiae s.l. larvae abundance and modelled the larval distribution of this species in Baringo County, Kenya. Mosquito larvae were collected using a 350-mL dipper and a pipette once per month from December 2015 to December 2016. A random forest algorithm was used to generate vegetation cover classes. A negative binomial regression was used to model the association between remotely sensed climate (rainfall and temperature) and environmental (vegetation cover, vegetation health, topographic wetness and slope) factors and An. gambiae s.l. for December 2015. Anopheles gambiae s.l. was significantly more frequent in the riverine zone (P < 0.05, r = 0.59) compared with the lowland zone. Rainfall (b = 6.22, P < 0.001), slope (b = - 4.81, P = 0.012) and vegetation health (b = - 5.60, P = 0.038) significantly influenced the distribution of An. gambiae s.l. larvae. High An. gambiae s.l. abundance was associated with cropland and wetland environments. Effective malaria control will require zone-specific interventions such as a focused dry season vector control strategy in the riverine zone.
