| ABSTRACT: In the search for improved yields, seed treatment by microbiolization has been used as an alternative to chemical treatment. The objective was to verify the physiological and sanitary quality of creole bean seeds, var. Chumbinho, after microbiolization with doses of a commercial product (c.p.) with Trichoderma harzianum (strain ESALQ-1306). The treatments were: T1) 100 mL c.p./100 kg seeds; T2) 150 mL c.p.; T3) 200 mL c.p.; T4) 200 mL of chemical treatment (c.p., 250 g L-1 fipronil + 25 g L-1 pyraclostrobin + 225 g L-1 thiophanate-methyl); and T5) control (without coating of seeds). The tests were: sanitary test (blotter test); germination and first count; accelerated aging, cold germination without soil, speed of germination rate (SGR), seedling... |

| Several polyphagous arthropod predators are commercially available for augmentative biological control targeting mite and insect pests in a variety of cropping systems. A number of these predators are not native to the area of release. The current paper discusses benefits and risks of using exotic generalist predators as biocontrol agents. The fact that polyphagous predators are easily reared on unnatural foods and can be used against different pest species makes them attractive for commercialization. Polyphagous or facultatively phytophagous predators have less difficulty in maintaining their populations at low prey densities and can sometimes be introduced in the crop before the target pest is present, thus preventing the buildup of pest populations... |

| This work aimed to evaluate the Deladenus siricidicola, Bedding (Neotylenchidae)parasitism in adults Sirex noctilio, Fabricius, 1793 (Hymenoptera: Siricidae). Timber was sampled by cutting out pieces of 0.80 m in length in Sirex noctilio attacked and Deladenus siricidicola inoculated Pinus taeda. Longs were 15-20 cm in diameter, according to the tree age. Samples were packed in gauze-cages, for daily observations, till S. noctilio adults emergence. The emerged insects were transported, in plastic containers to the laboratory, where they were sectioned and dissected under stereoscopic microscopy to observ the nematode occurrence. From the initially proposed ten units, nine of them were evaluated in a total of 1,810 emerged adult insects, being 1,441 males... |

| Ophyra albuquerquei may often be a potential predator of Musca domestica Linnaeus, 1758 in poultry and pig houses in southern Brazil. Here we address the developmental period of immatures stages and their viability. To obtain eggs, larvae and pupae, a colony was established in the laboratory. Adult flies were fed on a diet comprising two parts dry milk, two parts sugar and one part fish flour. Larval diet comprised one part fish flour and one part sawdust and water. The eggs, larvae and pupae were incubated at 26º ± 1ºC, 75% ± 10% R.H. and 12 h photoperiod. The egg to adult cycle took 573 h with a total viability of 64%. The shortest of the stages was the egg stage, which lasted about 20 h. The larval stage had the lowest viability (about 82%) and longest... |

| Nymphs of Podisus nigrispinus (Dallas, 1851) were fed with Zophobas confusa Gebien, 1906, Tenebrio molitor Linnaeus, 1758 (Coleoptera, Tenebrionidae) and Musca domestica Linnaeus, 1758 (Diptera, Muscidae) under 25±0.5ºC, 60±10% of RH and photophase of 12h. Nymphal viability of P. nigrispinus were 64.0%, 80.0% and 92.0% with Z. confusa, M. domestica and T. molitor, respectively. No differences were found for pre-oviposition period, number of egg masses, number of eggs, egg viability, and longevity for females of this predator fed with any of these preys. |

| The giant conifer aphids Cinara pinivora (Wilson, 1919) and Cinara atlantica (Wilson, 1919) (Hemiptera: Aphididae) are pests on Pinus spp. (Pinaceae) in the South and Southeast regions of Brazil. Larvae of Chrysoperla externa (Hagen, 1861) (Neuroptera, Chrysopidae) were observed feeding voraciously on these aphid colonies. In order to evaluate their potential as biological control agents, some biological parameters and their consumption capacity were studied in laboratory. Ten larvae were isolated in plastic vials and fed with aphids of small size (nymphs of 1st and 2nd instars) and 10 with aphids of medium size (nymphs of 3rd and 4th instars), maintained at 15ºC, 20ºC and 25ºC, under 12:12 h photoperiod and 70 ± 10% RH, and observed daily. The egg... |

| The aim of this study was to evaluate the development and reproduction of P. nigrispinus in laboratory when fed with T. arnobia reared on guava leaves. This predator showed nymphal stage of 21.11 days, survival of 60% and periods of pre-oviposition, number of eggs/mass and eggs/female and egg viability of 6.10 days, 26.24 eggs, 314.90 eggs and 82.65%, respectively. These results demonstrated that T. arnobia fed with guava leaves was an adequate supply of food to P.nigrispinus. |

| All research steps, developed from 1995 to 2000, to synthesize the sex pheromone of Ecdytolopha aurantiana (Lima, 1927) are described, in order to monitoring this pest that causes losses in the order of 50 million dollars per year to citriculture in the State of São Paulo. The basic researches conducted are described, including the development of an artificial diet for the insect, the study of its temperature and humidity requirements, behavioral studies, and synthesis of the male-attracting substance up to the formulation and distribution of the pheromone to the grower, by means of its commercialization. It is a case of success, at a cost of 50 thousand dollars, involving inter- and multidisciplinary researches, which can be adopted to other insect pests... |

| 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. |

| Diapause has been poorly investigated in tephritid fruit flies and in associated parasitoids in tropical regions. In this work, diapause in larval-pupal parasitoids of fruit flies is reported for the region of the Reconcavo Baiano, Brazil. Diapause was recorded for individuals of four native species [Doryctobracon areolatus (Szépligeti), Utetes anastrephae (Viereck), Opius sp. (Hymenoptera: Braconidae), Aganaspis pelleranoi (Brethes) (Hymenoptera: Figitidae)] and of one exotic braconid [Diachasmimorpha longicaudata Ashmead]. Diapausing parasitoids were obtained from fruit fly puparia in fruits collected between November 1998 and April 2000. In all, 1.4% of individuals underwent diapause, being D. areolatus the most frequent. The development time for this... |

| Instalado na area experimental da EMBRAPA-UEPAE Porto Velho, visando controlar o ataque das cigarrinhas-das-pastagens em Rondonia. Foi iniciado em jan./1977, com seis piquetes de 1ha cada um, com pastagens de brachiaria decumens. Tres piquetes foram adubados com fosforo, 100kg/ha, e tres nao adubados. Cada piquete comportou tres garrotes de dois anos de idade.As ninfas foram contadas atraves de um quadro de madeira medindo 0,25m de lado, jogado 10 vezes ao acaso por piquete. O processo de contagem dos adultos foi feito atravesde uma rede entomologica de 0,4m de diametro. Conclui-se que: apos seis meses de aplicacao ainda encontrou-se cigarrinhas mortas; o fungo atinte jovens e adultos; apos aplicacao do fungo houve rapida recuperacao das pastagem, embora... |
