“…For example, Huber et al (2004) found that in Ho Chi Minh City (Vietnam), the level of genetic differentiation among populations from the outskirts of the city, where human density is lower and water is stored in open containers, is twice as high as among populations in downtown areas, where human density is high and there is a piped water supply. Similar results were obtained in other Southeast Asian cities, such as Chiang Mai in Thailand (Mousson et al 2002) and Phnom Penh in Cambodia (Paupy et al 2004a, b). Climatic factors, such as seasonality of temperature and rainfall, also influence the level of genetic differentiation among mosquito populations.…”

“…The periodicity of application of insecticide treatments was found to be another factor that determines the genetic structure of Ae. aegypti because treatments cause periodic population bottlenecks that enhance genetic differentiation, as reported for populations from Cali (Colombia) (Ocampo & Wesson 2004) and several Asian cities (Mousson et al 2002, Paupy et al 2005.…”

“…The use of genetic markers has led to the recognition of a number of cryptic species and divergent evolutionary lineages (Schaffner, Raymond & Pasteur 2000;Ravel et al . 2002;Chen, Harbach & Butlin 2004), whose vector competence and/or susceptibility to insecticides are significantly different in several cases (Mousson et al . 2002;Yébakima et al .…”

Summary 1.Rationalizing the use of chemicals in pest control programmes is a fundamental goal that is aided by the knowledge of patterns of population connectivity and historical demography. 2. In this study, we used both mitochondrial and nuclear markers to investigate the genetic structure and diversity of the northern Italian populations of Ochlerotatus caspius , a mosquito of great public health and economic impact in Mediterranean countries. 3. A substantial genetic homogeneity was found among populations, with no association of pairwise population differentiation with the geographic distribution or the environmental heterogeneity of the breeding sites. 4. On a regional scale, we hypothesize a historical demographic expansion, probably associated with late Pleistocene palaeoclimatic events. Furthermore, our results suggest that ever since the expansion event, an extensive gene flow is still the major evolutionary force shaping the overall genetic pattern observed. 5. At a local geographic scale, evidence of recent growth in the size of the population was found in several sites. The increased availability of large breeding sites offered recently by rice paddies seem to have played a major role in giving rise to the observed demographic expansions. Indeed, these sites have become more numerous and undergone changes in the management technique (increased number of dry/flood cycles), which enhanced their suitability as breeding habitats. 6. Synthesis and applications . The migration pattern among populations of Oc. caspius in northern Italy appears to be high enough to maintain an extensive genetic homogeneity. Control programmes on a small geographic scale are thus unlikely to be effective. The modern agronomic techniques and the growth of rice paddies seem to have played a role in the recent demographic history of the species in the Po plain. Therefore, satisfactory control programmes should: (i) be focused mainly on rice paddies as breeding habitats; (ii) favour agronomical techniques involving a reduced number of dry/flood cycles; (iii) be carried out on a wide (regional) geographic scale; and (iv) monitor periodically the susceptibility of populations to the compounds used in control campaigns and adopt strategies aimed to avoid the possible spread of resistance alleles.

Factors influencing the population structure of Aedes aegypti from the main cities in Cambodia

A population genetic analysis was conducted on 47 Aedes aegypti collections from Cambodia. Genetic differentiation at seven polymorphic isoenzyme loci was analysed by starch gel electrophoresis. Low (F ST ¼ 0.024) but significant (Po10 À6 ) differentiation was found when all samples were considered. Whatever the grouping of samples tested, differentiation remained significant but low. The role of human activities (ie insecticide treatments or water storage practices) and environmental factors (ie rainfall) in shaping mosquito differentiation are discussed.
