Haplotype characterization of the COI mitochondrial gene in Chrysoperla externa (Neuroptera: Chrysopidae) from different environments in Jaboticabal, state of São Paulo, southeastern Brazil

Abstract

The green lacewings (Chrysopidae) belong to the Order Neuroptera and are described as voracious predators in the larval stage and sometimes also in their adulthood. They are an important group used in integrated biological control in field and horticultural crops. Individuals of Chrysoperla externa were collected during 2007 until March 2008 in five different locations in Jaboticabal, SP, with all the seasons sampled. Thirty six sequences with 805 pairs of bases for the gene mitochondrial Citochrome Oxidase I (COI) were analysed. The genetic parameters revealed 24 haplotypes for this population, a total of 36 mutations and haplotype diversity of 0.956. The data of genetic distance and population structure calculated for this population considering the different areas and seasons, revealed a great genetic similarity and high degree of genetic sharing between individuals sampled. It showed that the species Chrysoperla externa from Jaboticabal, SP, is a single population, without genetic structure neither due to the area of origin nor to the seasons of the year.Keywords: Chrysoperla externa, green lacewing, mitochondrial DNA, population structure.

MOLECULAR SYSTEMATICS OF Chrysoperla carnea GROUP (NEUROPTERA: CHRYSOPIDAE) IN PUNJAB, PAKISTAN

“…Similarly the species C. corpominus showed 74% similarity with C. modests. These results are in agreement with Andras et al 2009, Morales and Freitas, 2010, Haruyama et al 2008and Winterton and Freitas, 2006. A third group contained only a single species Chrysoperla carnea that did not make any group with rest of the four species and showed a minimum similarity (55%) with species C. yunusi.…”

“…The introduced pest-controlling agent will only be established successfully if the environmental pressure factors are matched by their corresponding support capacities (Morales & Freitas 2010). Climatic conditions play an important role in tritrophic interactions among poikilotherms, as they influence the level of control that natural enemies exert (Huffaker et al 1971).…”

Aspects of the color evolution after the imaginal molt of Pachycoris torridus (Scopoli, 1772) (Hemiptera: Scutelleridae)

“…For presenting variations in patterns of colors and stains from their body, has already been described eight times as new species (Lima, 1940). The correct specific identification is essential for success in programs of biological control and therefore the knowledge of intraspecific variation is fundamental in this identification (Morales and Freitas, 2010). In this context, this work was conducted with the objective to contribute with details on the evolution of coloration of P. torridus after the imaginal molt and avoid that new taxonomic errors occur.…”
