| 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... |

| From September 2001 through September 2002, house fly and stable fly pupae were collected weekly from three fly habitats at the University of Florida Research dairy in northcentral Florida and evaluated for parasitism. Varying parasitism percentages were observed throughout the study but they were not affected by temperature, precipitation or fly abundance. Of the 6,222 house fly pupae and 1,660 stable fly pupae that produced either a host fly or a parasitoid, 26.9% and 26.7% were parasitized, respectively. Ten parasitoid species were recovered, with the genus Spalangia accounting for 85.7% of the total; the most common parasitoids attacking house fly and stable fly pupae were Spalangia endius Walker (33.9% and 27.3%), S. cameroni Perkins (27.9% and... |

| 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.... |

| 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... |
