The goal of this study was to reveal the genetic structure of C. Chrysopidae is the most studied neuropteran predator fhrysoperla Brazil, occurring in diverse crops, with high predatory capacity. Data analysis The sequences were read in Chromas Lite v.

Abstract This work aimed to elucidate the distribution of Chrysoperla externa haplotypes and investigate whether it exhibits structure based on genetic composition as opposed to geographic location. Life his-tory and potential for chrysoperrla control in Central and South America. 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.

Junk Publishers, The Hague. The extern hatched larvae of C. It is concluded that N. Analysis showed significant genetic structure among the sampled groups, which, combined with its within-group absence, corroborated group identities [ 7 ].

Discussion 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. We evaluated biological and reproductive aspects of Chrysoperla externa fed with the aphid Neotoxoptera formosana reared on Welsh onion Allium fistulosum. The complete biological cycle of C. Nucleotide composition was calculated by MEGA v.

Chrysopidae fed with Neotoxoptera formosana Hemiptera: It was observed that the average production of chtysoperla increased until the twentieth day, when it reached its peak, and thereafter steadily declined, equaling to the average initial production on the thirty-third day of oviposition. The green lacewings of the world: Chrysopidae bajo diferentes temperaturas.

Chrysopidae alimentada com Schizaphis graminum Rondani, Hemiptera: How to cite this article. Aphids were collected in home garden plants and multiplied on Welch onion A.

Figure 4 also reveals that the daily consumption of nymphs typically increased with increasing temperature. For oviposition period and egg laying, Santos et al. Cereal aphid flights and barley yellow dwarf virus infection of cereals in Canterbury, New Zealand. Infestation levels of improved sorghum cultivars with Rhopalosiphum maidis Exterma and Eublema gayne-ri Roths in Senegal. These results demonstrate that in addition to the species of aphid, host plant influences positively or negatively the performance of its predator.
