| Muitas das espécies de insetos associadas ao plantios de eucalipto são consideradas pragas, enquanto outras ainda não apresentam uma relação definida com estas florestas. Amostragens quinzenais da entomofauna, realizadas com armadilhas luminosas, no período de agosto/90 a julho/91, revelaram a existência de 263 espécies de Lepidoptera associadas aos plantios de eucalipto da região de Açailândia (Maranhão). Destas, sete são consideradas pragas primarias: Eupseudosoma aberransSchaus, 1905 e Eupseudosoma involutaSepp, 1852 (Arctiidae), "Thyirrteina leucoceraeaRindge, 1961, Glenaspp., e Oxydia veuliaCramer, 1779 (Geometridae); Nystalea nyseusCramer, 1775 (Notodontidae); Sarsina violascensHerrich-Schaeffer, 1856 (Lymantriidae) e seis pragas sencundárias:... |

| 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... |

| In this work, the effect of different densities (1, 3, 5, 7 and 9) of 3rd instar Alabama argillacea (Huebner) larvae on food consumption by Podisus nigrispinus (Dallas) males was evaluated. The densities established were converted to weight of prey offered: 13.4 mg (one larva), 33.3 mg (three larvae), 54.3 mg (five larvae), 81.8 mg (seven larvae), and 110.34 mg (nine larvae). The quantity of food consumed by P. nigrispinus increased with the prey density. The density of preys did not affect the time spent by the predator to ingest the food. The quantity of food extracted per minute was always higher in smaller densities and lower in higher densities. Males mean body weight did not differ statistically between the treatments tested, and weight gain was... |

| This study presents the effect of a supplementary diet with amino acids and sodium chloride solutions in addition to prey on the development, survival and reproduction of the predator Podisus nigrispinus (Heteroptera, Pentatomidae). Both solutions showed deleterious effects on nymph survival, adult weight, female longevity, number of egg masses, eggs per female, eggs per egg mass and nymphs per female besides egg viability of P. nigrispinus when compared with diet with water and prey. When compared with plant supplements in the diet the use of amino acids and salt solutions for mass rearing of P. nigrispinus was inferior. |

| 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... |

| Pupae of Thyrinteina arnobia (Stoll) and Thyrinteina leucoceraea Rindge (Lepidoptera: Geometridae) were obtained from Eucalyptus cloeziana F. Muell and Eucalyptus urophylla S.T. Blake plants, respectively. Specimens of a parasitoid emerged from T. arnobia pupae and also found parasitising T. leucoceraea pupae in the field were identified as Palmistichus elaeisis Delvare and LaSalle (Hymenoptera: Eulophidae). This is the first report on P. elaeisis parasitizing T. arnobia and T. leucoceraea pupae in natural conditions in Brazil. P. elaeisis also parasitized these hosts and Bombyx mori Linnaeus (Lepidoptera: Bombycidae), Anticarsia gemmatalis Hubner, Pseudaletia sequax Franclemont, Alabama argillacea Huebner (Lepidoptera: Noctuidae), Dirphia moderata Bouvier... |

| This work investigated the potential of Tyrophagus putrescentiae (Schrank) (Astigmata: Acaridae) to control Lasioderma serricorne (F.) (Coleoptera: Anobiidae) in the laboratory. L. serricorne is the most destructive insect pest ever found on stored tobacco. The experimental delineation had 33 arenas being each experimental unit with 11 arenas of experiments with eggs, larva of L. serricorne with the density of T. putrescentiae maintained constant, where from 11 of these arenas, eight were for the analysis of predation and three to evaluate the natural mortality of the insect. The highest predation rate was found during the larval stage with, approximately, 54, 68 and 78% mortality of L. serricorne from the fourth until the sixty day of predation. These... |

| Thyrinteina arnobia, is one of the most important defoliating caterpillars of Eucalyptus in Brazil The objective of this work was to evaluate the development and the reproduction of feeding on leaves of guava (Psidium guajava) or Eucalyptus grandis in the 15th generation, after rearing this species for 14 genrations on guava leaves. T. arnobia showed shorter larval period, better viability of caterpillars and pupae, heavier pupae, higher number of eggs per female, better egg viability and shorter longevity of females in guava leaves than in Eucalyptus leaves. The better development and reproduction with P. guajava showed that this insect could be reared in laboratory with guava leaves. |

| The objective of this work was to determine the fecundity of the predator Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) females of two weight classes aiming to define, which one presented higher productivity in the laboratory. Males and females of B. tabidus were reared from nymphs fed with Tenebrio molitor L. (Coleoptera: Tenebrionidae) pupae in laboratory. Females of B. tabidus weighting 95 to 150 mg and those with 160 to 220 mg constituted two treatments. Oviposition period and numbers of egg masses, eggs and nymphs per female of B. tabidus were higher in the treatment with heavier females, while the periods of preoviposition, between egg mass laying, egg incubation and number of eggs per egg mass, besides the percentage of nymphs hatched... |
