| The aim of this study was to describe mitotic and meiotic chromosomes of Cycloneda sanguinea using C-banding, fluorescent in situ hybridization (FISH) rDNA probes, and sequential FISH/Ag-NOR staining. The chromosome number was 2n = 18 + XX for females and 2n = 18 + Xy for males. The X chromosome was metacentric and the Y chromosome was very small. During meiosis, the karyotypic meioformula was n = 9 + Xy p, and sex chromosomes configured a parachute at metaphase I. At the beginning of pachytene, bivalents were still individualized, and sex chromosomes were associated end-to-end through the heteropycnotic region of the X chromosome. Later in pachytene, further condensation led to the formation of a pseudo-ring by the sex bivalent. All chromosomes showed... |

| Estudou-se a seletividade dos inseticidas cipermetrina, diclorvós, diazinon, etion, fenitrotion, malation, metamidofós, paration metílico, permetrina, pirimicarbe e vamidation para adultos dos predadores Cycloneda sanguinea (L.) e Eriopis connexa (Germ.)(Coleoptera: Coccinellidae). Folhas de tomateiro foram imersas em caldas inseticidas nas doses utilizadas para o controle dos pulgões Myzus persicae (Sulzer) e Macrosiphum euphorbiae (Thomas) em tomateiro e também na metade das doses recomendadas. Os fatores em estudo foram os inseticidas, as doses, as espécies de predadores e o sexo para C. sanguinea. Vamidation e o pirimicarbe foram os inseticidas mais seletivos a C. sanguinea seguidos do etion e diclorvós (3,2; 6,7; 49,7 e 52,5% de mortalidade,... |

| The objective of this work was to compare biological aspects and life table parameters of the coccinellids Harmonia axyridis, Cycloneda sanguineaand Hippodamia convergens. Insects were fed eggs of Anagasta kuehniella, and reared at 24.5±1ºC, 70±10% relative humidity, with a 12 hour photophase. Hippodamia convergenstook about 1.6 day to complete development, longer than H. axyridis, and 2.4 day longer than C. sanguinea.At immature stages, H. axyridisexhibited the highest survival percentage (49.2%), in comparison to the other coccinellids. For mean adult longevity, H. convergenswas deficient, in comparison with the other species. Mean period of pre oviposition was the longest in C. sanguinea; the longest oviposition time occurred for H. axyridis; and the... |
