Abstract: Lasioderma serricorne (F.) is a small cosmopolitan beetle regarded as a destructive pest of several stored products such as grains, flour, spices, dried fruit and tobacco. Chemical insecticides are one of the measures used against the pest. However, intensive insecticide use has resulted in the appearance of resistant insect populations. Therefore, for the elaboration of more effective control programs, it is necessary to know the biological aspects of L. serricorne. Among these aspects, the genetic variabilit… Show more

“…Moreover, esterase analysis indicated high degree of genetic polymorphism between EB and SL populations of S. oryzae. The results in line with that reported by (Coelho-Bortolo et al, 2016) in which genetic variance might be attributed to wide geographical distribution and importing of stored product commodities. Esterase isozymes in insects often show large polymorphism that resultant in strong selection pressure such as what was recorded in T. castaneum (Price, 1984) and O. surinamensis (Lee and Lees,2001) and (Silva and Lapenta 2011).…”

“…Heterozygous deficiency is not the only pattern that has been found in stored-product insects, other species have shown an excess of heterozygotes that was attributed to bottlenecks caused by fumigation or heat control tactics (Fields and White 2002; Semeao et al 2012; Coelho-Bortolo et al 2016; Blanc et al 2006). Nonetheless, we must be careful interpreting and generalizing conclusions from inbreeding coefficients such as F IS as such coefficients are more related to properties of the mating system within the population rather than evolutionary processes that lead to divergence among populations such as F ST coefficients (Holsinger and Weir 2009).…”

“…We have found a significant degree of isolation in populations from CA, WA, and TX, and because those locations also have the most substantial average distance to other places, isolation by distance (IBD) can be implied. Other studies on stored product insects have found a significant degree of structure but lack of IBD (Bas et al 2000; Drury et al 2009; Semeao et al 2012; Coelho-Bortolo et al 2016; Thangaraj et al 2016), which led to the prevalent hypothesis that human-aided movement was a more critical factor than flight dispersal in defining population structure (Drury et al 2009). Here we found that geographic distance can play a significant role in population structure even in stored-product insects with a high degree of predicted anthropogenic movement, at least at a large geographic scale.…”

“…According to Jain et al (2010), rAPD markers generate consistent results, produced in optimized conditions, and are useful for phylogenetic inferences and taxonomic classification. This molecular marker has an advantage of the possibility of using a different set of primers and choosing the best for each analysis as different sets of primers often produce different banding patterns that can be used in a variety of studies (Yulin et al 1998, grutzmacher et al 2007, Johnson et al 2008, Zahoor et al 2013, Coelho-Bortolo et al 2016, Preet and gupta 2017. Therefore, these markers have several entomological applications, for example, in forensic entomology, breeding programs, taxonomic identification of pests of agronomic interests, detection of genetic variation among populations, as well as, in the identification of closely related species (Grzywacz et al 2012, ercan et al 2012, Sivasankaran et al 2013, Matta et al 2013, Sunitha et al 2015, Singh et al 2016, Haghighi and Kumar 2017, Queiroz et al 2017, Sharma and Singh 2017.…”

“…Yadav et al (2017) argue that the results of the genetic variability of important economic pests provide useful information that could be used to design suitable strategies to control the spreading of these pests. It may also be useful in determining chemical control methods in relation to a specific host crop and in the management of resistance to insecticides (Coelho-Bortolo et al 2016, Queiroz et al 2017, Yadav et al 2017.…”
