| An age-mass structured multi-year tritrophic simulation model of the coffee (Coffea arabica var. mundo novo) - coffee berry borer [Hypothenemus hampei (Ferrari)], borer - three parasitoid system was developed. Three years of extensive plant drymatter data and one year of field data on borer dynamics were collected at Londrina, PR, Brazil. The allometric relationships and parameter for plant drymatter allocation were estimated from the field data, but the parameters for borer and its three parasitoids were summarized from the literature. Initial levels of soil factors (e.g., nitrogen and water) and observed weather data were used to drive the model. The model is largely independent of the field data, yet it simulated the dynamics of plant branching,... |

| The genetic variability of 27 individuals from two distinct populations (Northeast and Central Brazil) of the grasshopper Schistocerca pallens (Thunberg) and eight isolates of its natural pathogen, the fungus Metarhizium flavoviride Gams & Rozsypal, was investigated using RAPD analysis. For the grasshoppers, ten different 10-mer oligonucleotide primers of arbitrary sequence were selected for analysis, resulting in 79 scorable binary characters. The program RAPDDIP applied to S. pallens revealed nucleotide diversity of 2.3 and 2.2% for the populations from Rio Grande do Norte (Northeast Brazil) and Federal District (Central Brazil), respectively. These values indicate the presence of high genetic variability within these populations. Conversely, the... |

| A survey of Hymenoptera parasitoids fauna was made in a transect of Eucalyptus/native vegetation/Eucalyptus in Ipaba, state of Minas Minas Gerais, Brazil from March 1997 to March 1998 with Malaise traps. Individuals of nine superfamilies were collected (Ceraphronoidea, Chalcidoidea, Chrysidoidea, Cynipoidea, Evanioidea, Ichneumonoidea, Proctotrupoidea, Platygastroidea and Vespoidea) which belong to 26 families of this order. |

| Este estudo teve como objetivo determinar as espécies de parasitoides associados com moscas coletadas em vísceras de galinha, em Itumbiara, Goiás. Armadilhas contendo vísceras de galinha como isca foram utilizadas para atrair a moscas. As pupas, obtidas pelo método de flutuação, foram colocadas individualmente em cápsulas de gelatina (nº 00) e mantidas em laboratório até a emergência das moscas e/ou dos parasitoides. A prevalência total de parasitismo foi de 20,0%. Brachymeria podagrica, Hemencyrtus sp. (Hymenoptera: Encyrtidae), Nasonia vitripennis (Hymenoptera: Pteromalidae), Paraganaspis egeria (Díaz, Gallardo & Wash) (Hymenoptera: Figitidae), apresentaram prevalência de parasitismo de 8,9%, 10,8%, 0,9% e 0,3%, respectivamente. |

| Four isolates of Trichoderma harzianum (ThN3, Th11, Th12 and Th16) were selected for their ability to control the in vitro development of the tomato root pathogen Pyrenochaeta lycopersici. Analysis of the mechanisms involved in biocontrol showed that the formation of non-volatile metabolites appears to be one of those involved in biocontrol of P. lycopersici by all T. harzianum isolates tested. Nevertheless, the higher secretion of chitinases, both in number of isoenzymes and activity by the Th11 strain, correlated well with its higher ability to control this agent in laboratory and greenhouse experiments as compared to the other T. harzianum isolates tested. The secretion of ß -1,3-endoglucanases and/or proteases appeared to have less significance than... |

| The stinkbug Supputius cincticeps (Stål) (Heteroptera: Pentatomidae) can be found in agricultural and forest ecosystems feeding primarily on larvae of Coleoptera and Lepidoptera, where it can be exposed to insecticide applications. This study therefore aimed to evaluate the reproductive potential of'S. cincticeps after exposition to sublethal doses of permethrin (5.74 x 10-3, 5.74 x 10-2, 5.74 x 10-1, 5.74 and 57.44 ppb) through the use of a fertility life table. The development cycle of this predator was determined in order to calculate its net reproductive rate (R0), the infinitesimal (r m) and finite (λ) rates of increase in addition to mean generation time (T). The net reproductive (18.31), infinitesimal (r m) (0.050) and finite (λ)... |

| Abstract The objective of this study was to evaluate the potential of the pioneer plant species Bellucia grossularioides (L.) Triana (Melastomataceae) to act as a reservoir for parasitoids of fruit flies in the Brazilian Amazon. We collected 48 samples of fruits (total of 4,012 fruits, 43.98 kg) during the months of July, August and September of 2013, in 15 of the 16 municipalities of Amapá State, Brazil. All samples showed infestation by fruit flies, with rates varying from 60.6 to 239.1 puparia/kg of fruit (mean of 106.8 puparia/kg of fruit). The percentage of emergence varied 18.6 to 64.3% (mean of 39.9%). Specimens of Anastrepha coronilli Carrejo & González (Diptera: Tephritidae) were obtained from all samples collected. Specimens of Neosilba... |
