This was viewed and edited in FigTree v. The sen-sitivity of pupae to low temperatures may be associated with the physiological problems described by Chapman Statistical tests of neutrality of mutations against population growth, hitchhiking and background selection.

All the specimens were collected in open areas and on agrosystems borders. For the longevity of males and females and the average daily production of eggs, we calculated, respectively, the curves of survival probability and the curve of average oviposition according to the age of the females, using the free software R R Development Core Team Ciencia e Agrotecnologia 32 4: The Welsh onion Allium fistulosum L.


For 16Sthe structure analysis showed the separation into only two clusters Chrysopelra 4 with Group 4 remaining associated with Groups 1 and 3.

Effect of temperature on the interaction between Chrysoperla externa Neuroptera: Introduction The Welsh onion Allium fistulosum L. Our results demonstrated that C. Nested clade analyses of phylogeographic data: Its occurrence in Brazil was first reported by Souza-Silva and Ilharco Discussion Our results demonstrated that C.

Librado P, Rozas J.

These results suggest that the evolutionary history of C. The AMOVA demonstrated that haplotype differences among locations were not significant, showing that the distances between sampling sites, in Brazil and Paraguay, did not act as a barrier, and produced no cyrysoperla differentiation. Ciencia e Agrotecnologia Introduction Green lacewings are insects of the Chrysopidae, a family of 1, species and subspecies distributed among 82 genera [ 1 ].

Population dynamics of Chrysoperla externa Hagen Neuroptera: On this basis it is predicted that, under field conditions, the predatory capacity of C.

This was reflected in the network grouping. In other projects Wikimedia Commons Wikispecies.

Materials and methods Biological materials This study gathers new specimens of C. Thus, this research aimed to evaluate the development of C. Population structure The genetic structure was used to investigate the species C. These results show cbrysoperla, depending on the food provided to the larvae, the duration of the pre-pupa and pupa of C.

Population genetic structure reveals terrestrial affinities for a headwater stream insect.

Haplotype list of the 16S gene. National Center ezterna Biotechnology InformationU. Indeed, many control programs crucially depend on an understanding of the biology and physical requirements mainly tempera-ture of the predators Cividanes This Neuroptera related article is a stub. For oviposition period and egg laying, Santos et al.


Chrysoperla – Wikipedia

The curve with the daily average of eggs produced in relation to the age of C. Members of this genus and the genus Chrysopa are very common in North America and Europe. Bayesian analysis and neutrality test Bayesian inference analysis was performed to obtain the probable relationship between haplotypes of C.

This finding is in agreement with that of Chysoperla et al.

The presence of population structure was tested for the genes separately using a Bayesian approach with Structure v. This study gathers new specimens of C. Data Availability All relevant data are within the paper and its Supporting Information files. This did not occur in the present or externz previous studies of C.

Recent evolutionary history of Chrysoperla externa (Hagen ) (Neuroptera: Chrysopidae) in Brazil

The genetic diversity of C. This clear separation of haplotypes into clades of C. Positions from 1 to are for the COI gene, and from to are for the 16S gene.
