| O presente trabalho teve por objetivo avaliar a ação residual dos produtos etofemprox, fenitrotiom, metidatiom e triclorfom sobre adultos de Trichogramma pretiosum, bem como sobre as gerações F1 e F2 desse parasitóide, em condições de laboratório. Ovos do hospedeiro alternativo Anagasta kuehniella (Zeller) (Lep., Pyralidae) foram aderidos em cartelas de cartolina azul, inviabilizados sob lâmpada germicida e tratados por imersão nas soluções inseticidas e em água destilada (testemunha) por cinco segundos. Os ovos foram expostos ao parasitismo uma, 24 e 48 horas após o tratamento, por um período de 24 horas, e posteriormente mantidos em câmara climatizada a 24±1ºC, UR de 70±10% e 12 horas de fotofase até a emergência dos parasitóides.... |

| Euseius alatus DeLeon (Acari: Phytoseiidae) é um dos predadores mais comuns em fruteiras no Brasil, alimentando-se de pólen, ácaros e outros pequenos artrópodes. Este predador apresenta ampla distribuição, ocorrendo desde o Rio Grande do Sul até o Ceará. O presente trabalho teve como objetivo avaliar o efeito da temperatura no desenvolvimento e na reprodução de E. alatus e determinar suas exigências térmicas. O estudo foi conduzido a 18, 21, 24, 27, 30 e 33°C, umidade relativa de 70 ± 5% e fotofase de 12h. Nessas temperaturas, o período de ovo-adulto durou 14,0; 8,1; 5,5; 4,9; 3,8 e 3,1 dias, respectivamente. Os estágios de ovo, larva, protoninfa, deutoninfa e período de ovo-adulto apresentaram limiares térmicos de 12,52; 13,85; 14,86;... |

| Dichelops melacanthus was studied under controlled conditions (60 ± 10% RH and 14/10 h L/D photoperiod), and three constant temperatures (19, 25, and 31 ± 2 °C). Fresh pods of MON 87701 × MON 89788 soybeans and its near non-Bt isoline (A5547) were supplied to nymphs and adults. The biology of T. podisi was studied in the same controlled RH conditions, but only at the standard temperature of 25 ± 2 °C. Overall, the development of D. melacanthus was better at higher temperatures, which accelerated the development of the stink bug without affecting adult biological parameters. No influence of Bt-soybeans on the biology of the pest was observed in any temperature studied, which shows that D. melacanthus is not affected by this transgenic soybean. The egg... |

| ABSTRACT Coenosia attenuata Stein (1903) is a predatory fly that is commonly found in greenhouses and open fields preying on whiteflies, leafminers, psocopterans and other insects. The species is widespread in the Old World and its distribution has expanded in recent times to Neotropical countries including Chile, Colombia, Costa Rica, Ecuador and Peru. We report here for the first time the presence of C. attenuata in Brazil, occurring in different sites in the State of Ceará (Northeastern Brazil). Expansion of the distribution range of this muscid to the eastern parts of South America opens up the possibility of applying the beneficial predator as a biological control agent for protected crops of the region. |

| 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. |

| The effects of the egg density of Diaphania hyalinata (L.) on several biological parameters of Trichogramma exiguum Pinto & Platner and T. pretiosum Riley were investigated. For that, 24h-old egg masses were isolated in glass tubes (15 replicates; 1 egg mass = 1 replicate), and offered to parasitization by a newly-emerged female of T. pretiosum or T. exiguum 24h at the proportion of one female to 5, 10, 15, 20, 25, 30, 35 and 40 eggs of D. hyalinata. The following parameters were evaluated: number of parasitized eggs, number of individuals per egg, viability and sex ratio. Trichogramma exiguum parasitized more eggs than T. pretiosum when more than 25 eggs were available per female. The percentage of emergence was satisfactory to T. pretiosum in... |

| The nesting behavior of Podium denticulatum Smith was studied on the campus of Ribeirão Preto of the Universidade de São Paulo, SP, Brazil, from September 2003 to August 2005. The wasps established their nests in bamboo canes ranging from 11.4 cm to 26.2 cm in length and from 0.7 cm to 1.8 cm in internal diameter. Podium denticulatum nested almost exclusively in the hot and wet season (September-April), producing at least five generations per year. The cell provisioning was made with adult and nymphal cockroaches (Blattellidae) which were arranged venter-up and with the head inward toward the inner end of the cell. The construction of a temporary closure occurred in cells that took more than one day to be provisioned. The cells provisioned with a greater... |

| Spodoptera frugiperda (J E Smith) is an important pest of several crops, but especially on maize in Brazil. The implementation of biological control measures hinges on the identification of its predators and other natural enemies. As a means of identifying predators, antibodies against S. frugiperda eggs were generated by inoculating rabbits with macerated S. frugiperda eggs, and the production of antibodies against S. frugiperda egg proteins was verifi ed by double immunodiffusion (DID). These antibodies were then utilized in another serological technique, counterimmunoeletrophoresis (CIE), to identify insects that could have ingested S. frugiperda eggs. Macerates of entire insects collected in maize plantations and of individual parts of their digestive... |
