Development of Pseudacteon obtusus (Diptera: Phoridae) on Solenopsis invicta and Solenopsis richteri Fire Ants (Hymenoptera: Formicidae)
TLDR
Pseudacteon obtusus seems to be a promising candidate for biological control releases in that in addition to its high host specificity, it develops better on red fire ants, attacks ants on trails and mounds, and chooses a worker size range that complements the two other PseudACTeon species already released. Expand
Behavior and Development of Pseudacteon curvatus (Diptera: Phoridae) Varies According to the Social Form of Its Host Solenopsis invicta (Hymenoptera: Formicidae) in Its Native Range
TLDR
The rarity of polygyne S. invicta in its native range may prevent this phorid from adjusting its life history to that social form, and consequences of applying thisphorid in biological control are discussed. Expand
Chromosomal distribution of interstitial telomeric sequences as signs of evolution through chromosome fusion in six species of the giant water bugs (Hemiptera, Belostoma)
TLDR
The ITS distribution between these closely related species supports the hypothesis that several telomere–telomere fusions of the chromosomes from an ancestral diploid chromosome number played a major role in the karyotype evolution of Belostoma. Expand
Genotoxic effects of Roundup Full II® on lymphocytes of Chaetophractus villosus (Xenarthra, Mammalia): In vitro studies
TLDR
The present results confirm the genotoxic effects of RU on C. villosus lymphocytes in vitro, strongly suggesting that exposure to RU could induce DNA damage in C.villosus wildlife. Expand
Chaetophractus villosus as a sentinel organism: Baseline values of mitotic index, chromosome aberrations and sister chromatid exchanges.
TLDR
The large hairy armadillo is proposed as a sentinel organism for environmental biomonitoring of genotoxic chemicals due to its abundance, easy manipulation, well-known biology, the fact that it is usually exposed to different mixtures and concentrations of environmental contaminants, and the baseline values of genetic damage characterized by MI, CA, SCE and RI as biomarkers. Expand
Pseudacteon tricuspis: Its Behavior and Development According to the Social form of Its Host and the Role of Interference Competition among Females
TLDR
Why P. tricuspis sex ratios are always biased toward males in both social forms is discussed and it is suggested that similar studies of interference competition within and between already naturalized Pseudacteon species in the United States could help predict establishment patterns. Expand
Karyotype evolution in progress: A new diploid number in Belostoma candidulum (Heteroptera: Belostomatidae) from Argentina leading to new insights into its ecology and evolution
TLDR
The results obtained support the hypothesis that karyotype of B. candidulum originated through autosomal fusions and the fusion of the X and Y chromosomes with the ancestral NOR ­ autosomal pair and represent an excellent model for assessing the main mechanisms involved in the karyotypes evolution in organisms with holokinetic chromosomes. Expand
Cytogenetic analysis of three species of Pseudacteon (Diptera, Phoridae) parasitoids of the fire ants using standard and molecular techniques
TLDR
The apparent lack of morphologically distinct sex chromosomes is consistent with proposals of environmental sex determination in the genus, and small differences detected in chromosome length and morphology suggests that chromosomes have been highly conserved during the evolutionary radiation of Pseudacteon. Expand
Comparative study of mitotic chromosomes in two blowflies, Lucilia sericata and L. cluvia (Diptera, Calliphoridae), by C- and G-like banding patterns and rRNA loci, and implications for karyotype
Abstract The karyotypes of Lucilia cluvia (Walker, 1849) and Lucilia sericata (Meigen, 1826) from Argentina were characterized using conventional staining and the C- and G-like banding techniques.Expand
Behavioral Discrimination between Monogyne and Polygyne Red Fire Ants (Hymenoptera: Formicidae) in their Native Range
TLDR
Assessment of discrimination behaviors of both polygynous and monogynous forms of the red fire ant, Solenopsis invicta Buren, during symmetrical interactions in neutral arenas identified monogyne and polygyne forms of S.invicta colonies in concordance with current measures, including number of queens and expression of the Gp-9 gene.
