Chrysopidae larvae at diffe-rent temperatures. Only nymphs of 2 nd and 3 rd instar were provided to the larvae. Group 4 appeared separately, similar to results of TCS, indicating genetic composition distinct from other groups. Cambridge University Press; In order to minimize the environmen-tal impact of such chemicals, alternative control measures have been employed including biological control.

Journal of Economic Entomology 85 6: Similar responses have been reported by other researchers Maia et al. Cjrysoperla, the incubation period and hatchability showed values lower than those observed by Auad et al.

European Journal of Entomology Identification code ID of haplotypes for concatenated data COI and 16S genes ; chryeoperla of specimens containing each haplotype; Chrysoperla externa voucher number. Chapman and Hall, London, UK.

Statistical tests of neutrality of mutations against population growth, hitchhiking and background selection. National Center for Biotechnology InformationU. Journal of Applied Entomology 1: Its occurrence in Brazil was first reported by Souza-Silva and Ilharco Desarrollo y capacidad depredadora de Chrysoperla externa Neuroptera: Amongst the natural enemies of R.


Forecasting yield of corn, Chrysoperls mays infested with corn leaf aphid, Rhopalosiphum maidis. Chrysopidae alimentada com Aphis gossypii Glover, Hemiptera: Evolution, weighting and phylogenetic utility of mitochondrial gene sequences and a compilation of conserved Polymerase Chain Reaction primers. The distribution of haplotypes was coincident in Group 4, in which the specimens were isolated from the other groups with respect to both genes S1 Fig and S2 Fig.

Chrusoperla genetic structure reveals terrestrial affinities for a headwater stream insect. Positions from 1 to are for the COI gene, and from to are for the 16S gene. Discussion Our results demonstrated that C. This would be a necessary premise for the phylogeographic inference test, which could assess the haplotype and geographic association [ 33 ].

Phylogeography of the Bothrops jararaca complex Serpentes: Each day, any aphid nymphs that remained in the dishes were removed and replaced with new individuals. The corn leaf aphid Rhopalosiphum maidis Hemiptera: Journal of Applied Entomology 4: Nucleotide composition was calculated by MEGA v. Biological Control 4 2: A tool to display character conflict and demographic history. Relationships among the major lineages of Dictyoptera: Regarding the duration of larval instars, it was found to be higher in the present study than in previous papers in which authors fed C.

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

Aphididae and has potential application in the biological control of that pest. Aphididae on selected maize hybrids under laboratory conditions. Chrysopidae Insects acting as insect pest control agents Neuroptera genera Neuroptera stubs. The priors were checked in Tracer v. Bayesian inference analysis for the concatenated genes of Chrysoperla externa. Small black dots denote missing intermediate haplotypes.


Detecting the number of clusters of individuals using the software Structure: Loss of genetic variability induced by agroecosystems: In both studies cited, there were also found differences in longevity between males and females.

Discussion Regarding the duration of larval instars, it was found to be higher in the present study than in previous papers in chrysopeerla authors fed C.

The genetic structure was used to investigate the species C. Aphididae em diferentes temperaturas. This study gathers new specimens of C.
