| The B-strain of Bemisia tabaci Gennadius is a key pest of several crops and chemical control is the main control method used by growers, although reduction in efficacy due to insecticide resistance has already been reported. The aim of this work was to investigate the insecticidal effect of an array of synthetic sucrose esters with the aliphatic and aromatic groups on whitefly adults. Sucrose butyrate, caprate, octanoate, palmitate, oleate, octaacetate, phthalate, benzoate, and sucrose diacetate hexaisobutyrate were tested. The solutions were prepared and applied on the adults caught on yellow sticky traps using the Potter spray tower. Long-chains sucrose aliphatic esters were more effective against the silverleaf whiteflies and the highest mortality was... |

| O objetivo foi avaliar o parasitismo de ovos de Heliothis virescens em folhas das cultivares comerciais de algodoeiro de fibra branca (BRS 8H) e colorida (BRS Safira) por Trichogramma exiguum, Trichogramma pretiosum e Trichogramma atopovirilia. Trinta ovos da praga, depositados sobre folhas das respectivas cultivares, foram expostos a cada espécie do parasitóide por 48h, em condições controladas, nas quais foram mantidos até a emergência de seus descendentes. Entre as culturas, obteve-se o maior parasitismo na cultivar BRS 8H. T. atopovirilia e T. exiguum apresentaram maiores porcentagens de parasitismo, seguido por T. pretiosum. Os três parasitóides tiveram viabilidade de parasitismo acima de 90% e razão sexual de 0,79 a 1,0 em ambas as cultivares, mas... |

| Com intuito de subsidiar estratégias de manejo de pragas usando milho Bt no Rio Grande do Sul, onde são conhecidas e registradas diferentes populações de Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae), o objetivo deste trabalho foi avaliar os aspectos biológicos de populações dessa espécie provenientes de milho e arroz, oriundas de Pelotas- RS, mantidos em arroz e em milho expressando diferentes proteínas Bt. Avaliou-se sobrevivência e biomassa larval eimatura de duas populações de S. frugiperda mantidas em milho expressando proteínas Bt e em arroz. Os maiores valores de sobrevivência larval coincidiram com os maiores valores de biomassa (arroz e milho não Bt). Quanto à sobrevivência na fase imatura verificou-se que as larvas da... |

| O manejo integrado de pragas do feijoeiro-comum (MIP-Feijão), desenvolvido pela Embrapa Arroz e Feijão, visa auxiliar os produtores e técnicos nas decisões, racional e economicamente, para o controle de pragas do feijoeiro-comum. Para utilização dessa prática, se faz necessário o reconhecimento das pragas que causam danos à cultura, os inimigos naturais das pragas, a capacidade de recuperação das plantas aos danos causados pelos insetos, o número máximo de indivíduos das pragas que podem ser tolerados (nível de controle) e, quando necessário o controle, o uso de inseticidas de forma criteriosa. Com a utilização dessa tecnologia tem-se reduzido, em média, 60% das aplicações de inseticidas, com uma economia de 78% no custo de controle. Neste trabalho são... |

| An alert system for tomato late blight was validated in an Integrated Production System (IP) in the 2006-2007 and 2007-2008 season in Caçador, Santa Catarina State, Brazil. The late blight is a destructive disease and demands 25 or more fungicide sprayings per season in a Conventional Production (CP) System. For the CP area, the chemical control was according to the growers' production systems and consisted of weekly sprays soon after planting. For the IP area, the criterion for the first fungicide spray was according to Machardy (1972) and for subsequent ones according to Wallin (1962), when the disease severity values (DSV) reached eight points. There was a decrease on the fungicide application in the IP, not only in the number of fungicide sprays... |

| This research aimed at studing Telenomus remus Nixon biology reared on Spodoptera frugiperda (J.E. Smith) eggs at different temperatures. Based on the development of the cycle (egg-adult), the thermal requirements and the number of parasitoid generations at constant temperatures were determined. Initially, 24-hour-old S. frugiperda eggs were submitted to parasitism by T. remus during 5 h, being then transferred to acclimatized chambers regulated at 15, 20, 25, 28, 31, and 35°C. The cycle (egg to adult) was influenced by temperature varying from 8.3±0.01 to 47.2±0.01 for females and 8.1±0.01 to 46.8±0.01 days for males at 31 and 15°C, respectively. The emergency (%) was also influenced by temperature. A reduction in emergency was observed at 15°C and no... |

| The parameters of survival, development and reproduction of Podisus nigrispinus Dallas, 1851 (Heteroptera: Pentatomidae) may be affected by feeding on soybean (Glycine max L. Merr.; Fabaceae) cultivars. The direct effect was evaluated of the insect-resistant soybean 'IAC-24' (insect-susceptible soybean 'UFVS-2006' + pupae of Tenebrio molitor L., 1758 Coleoptera: Tenebrionidae versus 'IAC-24' plants + pupae of T. molitor) in the nymph and adult stages of the predator P. nigrispinus. The duration of the nymph stage was similar between treatments, but 'IAC-24' reduced the duration of the IV instar of this predator. The survival of P. nigrispinus was similar between treatments in the instars I, II, IV and V and in the nymph stage, but the survival of the III... |
