“…albopictus wing shape in male and female specimens and possibly other morphological and physiological traits (Virginio et al, 2015). and Louise et al (2015) used the same methodology to demonstrate that short periods of time (less than a year) are enough to result in detectable wing shape changes (Suesdek, 2019).…”

“…albopictus populations analyzed in this study. Wing shape pattern evolution may express flight activity changing behavior, intrinsic to the hostseeking process, host preference, vectorial capacity, and habitat suitability, among others (Morales Vargas et al, 2013;Suesdek, 2019;Chandrasegaran et al, 2020).…”

“…The evolution of populations within species and how this process impacts vector biology and epidemiology is not the only consequence of biotic factors (Suesdek, 2019;Chandrasegaran et al, 2020). Abiotic local factors, such as temperature, humidity, landscape, and presence of breeding sites could influence microevolution (Chandrasegaran et al, 2020).…”

“…Consequently, identifying the possible microevolutionary patterns that may affect the behavior of Ae. albopictus (Suesdek, 2019) is crucial. Environmental factors can affect mosquito bionomy traits such as longevity, body size, reproduction, larval development, and fecundity, among others (Chandrasegaran et al, 2020).…”

The Asian tiger mosquito Aedes albopictus (Skuse, 1894) is a highly invasive species widely distributed on the Spanish Mediterranean coast and the Balearic archipelago. Most studies involving this species in Spain have been focused on surveillance and control methods. However, micro-evolutionary studies for Ae. albopictus in Spain have been traditionally neglected. Morphological diversity could be the result of long-term evolutionary diversification in responses to selective pressures such as temperature, precipitation, food availability, predation, or competition that may influence flight activity, host-seeking, and blood-feeding behavior. Wing geometric morphometric have been used not only to study micro- and macro-evolution in mosquitoes but also in studies of population structuring and sexual dimorphism. Therefore, the main goal of this study was to investigate the wing shape patterns of Ae. albopictus populations to unveil sexual dimorphism that could provide information about their ecology and behavior. Mosquito eggs were collected using oviposition traps at the main campus of the University of the Balearic Islands (Palma de Mallorca, Spain) and reared under laboratory conditions. In order to study wing shape variation patterns in Ae. albopictus males and females, the left wing of each adult mosquito was removed and analyzed based on 18 landmarks. Our results indicated strong levels of sexual dimorphism between Ae. albopictus males and females. Furthermore, according to the cross-validated reclassification test, males were correctly distinguished from females with an accuracy of 84% and females from males 75%. We observed a significant sexual dimorphism in the wing shape patterns of Ae. albopictus when considering different seasonal patterns (spring vs. autumn). Our results suggested that selective pressures may affect males differently to females. Host-seeking, blood-feeding, and oviposition behavior of females may act as a major driver for wing shape sexual dimorphism. These results should be considered for the development of more effective and targeted mosquito control strategies.

“…The species phylogeny and taxonomy of the Culex genus is intricate and has been a matter of debate over the last decades [ 32 ]. Microevolutionary and speciation processes add an increased level of complexity to the correct identification of Culex species [ 33 ]. Cryptic species, such as the species complex formed by Cx.…”

Culex is the largest subgenus within the genus Culex that includes important vectors of diseases. The correct identification of mosquitoes is critical for effective control strategies. Wing geometric morphometrics (WGM) has been used to identify mosquito species alongside traditional identification methods. Here, WGM was used for eleven Culex species from São Paulo, Brazil, and one from Esquel, Argentina. Adult mosquitoes were collected using CDC (Centers for Disease Control) traps, morphologically identified and analyzed by WGM. The canonical variate analysis (CVA) was performed and a Neighbor-joining (NJ) tree was constructed to illustrate the patterns of species segregation. A cross-validated reclassification test was also carried out. From 110 comparisons in the cross-validated reclassification test, 87 yielded values higher than 70%, with 13 comparisons yielding 100% reclassification scores. Culexquinquefasciatus yielded the highest reclassification scores among the analyzed species, corroborating with the results obtained by the CVA, in which Cx. quinquefasciatus was the most distinct species. The high values obtained at the cross-validated reclassification test and in the NJ analysis as well as the segregation observed at the CVA made it possible to distinguish among Culex species with high degrees of confidence, suggesting that WGM is a reliable tool to identify Culex species of the subgenus Culex.
