Distinct genetic structure in populations of Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) shown by genetic markers ISSR and COI gene

Abstract

The family Chrysopidae is composed of approximately 1,200 species distributed in 80 genera (Freitas & Penny 2001). Larvae and adults exhibit distinct feeding habits, while adults are predators and/or consume pollen, nectar, and honeydew, all larvae are generalist predators. Larvae feed on various insects that are considered agricultural pests, such as aphids, mealybugs, and whiteflies, as well as lepidopteran eggs and larvae (Canard 2001; Freitas 2001; Papas et al. 2011). Green lacewings have a wide geographic distribution, being recorded worldwide except in Antarctica (Brooks & Barnard 1990). The genus Chrysoperla Steinmann, 1964 is one of the most studied green lacewing genera and comprises 36 described species. Only four species of this genus occur

Species identification and genetic diversity of Aedes in Penang (Malaysia) based on Cytochrome Oxidase Subunit I

“…albopictus (18) and Ae. aegypti (12) but the A+T composition range is comparable to the published study on mosquitoes based on COI DNA marker (e.g., Barbosa et al 2014;Gutierrez et al 2014;Pavana and Sebastian 2012). The number of substitutions for Ae.…”

Genetic diversity of Diaphorina citri and its endosymbionts across east and south‐east Asia

“…However, there was low genetic diversity and an absence of genetic structure among the populations of D. citri in east and south‐east Asia. These differences regarding population structure can be attributed to the lack of sequence variation of mt COI for the host, for following possible reasons: (1) the single mt COI marker, owing to the lower accumulation of substitutions compared to intergenic regions of nuclear DNA, reveals the evolutionary history of populations over a wide time scale, so that recently isolated populations tend to display high genetic similarities; and (2) host genes evolve slower than the bacterial genes. Bacterial symbionts sometimes evolve faster than the host because of an asymmetry in generation time, mutation rate, or importance of the interaction …”

Population Diversity of Odontotermes formosanus (Shiraki) (Termitidae, Macrotermitinae) from Different Geographic Locations in Anhui Province, China

“…In addition, the features of long sequence and high annealing temperature ensure that ISSR-PCR would exhibit high stability and reproducibility (Nagaoka & Ogihara, 1997;Tsumura et al, 1996;Qian et al, 2001;Naik et al, 2017). Although ISSR is widely used in studies on various plants (Qian et al, 2001;Cao et al, 2006;Tanya et al, 2011), fungi (Menzies et al, 2003) and some insects Dutta et al, 2012;Barbosa et al, 2014), but it was less used on the study of termites (Long et al, 2009).…”
