| The effect of the defense of the prey Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) on predation rates of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) females was studied. P. nigrispinus preyed 1.0, 1.4, 1.2, 3.8 and 3.0 and 0.4, 0.8, 1.6, 2.8 and 3.2 third instars of S. frugiperda larvae with and without defense, respectively, with the densities of one, two, four, six and eight larvae. The attack rate and the manipulation time were, respectively, 0.67 ± 0.39-h and 6.72 ± 2.88 h for P. nigrispinus females fed with larvae with defense and 2.51 ± 0.16-h and 0.51 ± 0.77 h for those without defense. The functional response of the predator P. nigrispinus varies with the defense and the density of the prey S. frugiperda, with larger... |

| The morphology of the reproductive tract of Podisus nigrispinus (Dallas) females fed with Alabama argillacea (Hübner) larvae, artificial diet, Tenebrio molitor L. larvae or Musca domestica L. larvae were studied. The reproductive tract of females of this species presented yellow coloration and independent of the diet, each ovary had seven ovarioles joined through terminal filaments and forming a bunch shape structure. The histological data revealed that the ovary of P. nigrispinus was of meroistic telotrophic type, with each individual ovariole divided in a terminal filament, a tropharium (trophic chamber), a vitellarium, and a pedicel. The prey type affected the development and morphometry of these structures. Females of P. nigrispinus fed with 3rd or 5th... |

| O objetivo deste trabalho foi avaliar a conservação pós-colheita de manga 'Tommy Atkins' orgânica destinada à exportação, colhida com Boas Práticas Agrícolas (CBP) e sem Boas Práticas Agrícolas (SBP), sob recobrimentos bio-orgânicos. Manga colhida na maturidade comercial foi recoberta com extrato de erva-doce a 1,5% (CBP+ED, SBP+ED), com extrato de erva-doce adicionada à fécula de mandioca a 3,0% (CBP+ED+F, SBP+ED+F) e Controle (sem recobrimento, CBP e SBP), armazenada a 10±0,5 ºC e 85±2% UR. O uso de BPA manteve a qualidade. O recobrimento com ED comprometeu a aparência da manga pela incidência de manchas na casca; recobrimento associando F + ED manteve a qualidade e retardou o amadurecimento. |
