Variability and genetic differentiation among Anopheles (Ano.) intermedius Chagas, 1908 and Anopheles (Ano.) mattogrossensis Lutz & Neiva, 1911 (Diptera: Culicidae) from the Brazilian Amazon

Genetic variability among populations of Crysomya megacephala (Diptera: calliphoridae) in India.

“…environmental conditions, genetic drift, population bottle neck, colonization, host availability and reproductive pressures are known to influence genetic variations within and among populations. In general the species populations distributed over a large variety of environmental conditions are known to be genetically more heterozygous as compared to the species with restricted distribution (Narang, 1980, Scarpassa and Hamada, 2003, Santos et al, 2005. It is interesting to note that all the calliphorids reveal large allelic diversities and microsatellite heterozygosities,( Torres and Azeredo-Espin,2005; Torres and Azeredo-Espin, 2008), a characteristic feature expected for a species with large population size.…”

“…Genetic variations among calliphorids using allozymes have been estimated only in Cochliomyia hominivorax (Taylor and Peterson, 1994;Taylor et al, 1995), C. macellaria (Taylor and Peterson,1994) and the present study.These flies were characterized by large heterozygosities as compared to other dipterans (Selander ,1976;Santos et al ,2005; Tripathi et al 2010) Large population size is responsible for greater genetic diversity as compared to small population size diversity (Krafsur et al, 1992, Krafsur and Griffiths 1997. Several factors eg.…”

RAPD-PCR-Based Genetic Relationships Among Three Forensically Important Calliphorid Species (Diptera: Calliphoridae)

“…The mean average heterozygosity in the three calliphorid species is greater as compared to other calliphorid species due to more variability of RAPD markers [24]. Thus, it seems that higher values of heterogeneity are reflected by greater population density as well as environmental changes, genetic drift, and population bottleneck within and among the populations [25][26][27][28]. The intra-specific genetic identity values in the three species (greater than 0.526), attribute that a narrow genetic pool is represented by the individuals of the same species 33.…”

Allozyme Diversity Inforensically Important Indian Species Chrysomya Megacephala (Fabricius) (Diptera: Calliphoridae)

“…It is interesting to note that calliphorids reveal large allelic diversity, a characteristic feature expected from a species with large population size. However, it is imperative that genetic characterization of geographically diverse populations of different Chrysomya species from India [24] should be The species populations dispensed over a massive style of environmental situations are regarded to be genetically extra heterozygous in comparison to the species with constrained distribution (Narang 1980, Scarpassa and Hamada, 2003, Santos et al 2005 [25][26][27] carried out with the help of allozymes and other molecular markers to evaluate the extent of genetic differentiation between population and also to get an insight into the process of bio-geographic patterns of genetic variations.…”
