| Os aspectos biológicos e etológicos são importantes parâmetros de medição da qualidade de inimigos naturais, na pesquisa ou criação de insetos para uso em controle biológico aplicado. Chrysoperla externa tem sido considerado um importante predador polífago, de hábito canibal, regulador de um grande número de insetos com status de praga da cultura do algodoeiro, entre outras. Este trabalho foi conduzido no laboratório de Entomologia da Embrapa Algodão, Campina Grande, PB, com o objetivo de avaliar algumas características biológicas e comportamentais de C. externa, criados em grupo de três larvas. Os insetos foram alimentados ad libitum com ovos de Ephestia (=Anagasta) kuehniella durante toda pesquisa. Foram avaliadas as fases larvais e larval total, os... |

| Bionomic data and larval density of Scarabaeidae (Pleurosticti) in sugarcane in the central region of Mato Grosso do Sul, Brazil. Phytophagous larvae of Scarabaeidae cause damage to diverse crops. Information on these pests is scarce; therefore, the objective of this study was to determine biological aspects and larval density of species occurring in an area of sugarcane. The studies were developed in Sidrolândia from April 2009 to March 2010. Scarab beetle larvae were collected in sugarcane roots every fifteen days, taken to the laboratory and reared to obtain the adults and determine biological parameters. A total of 2,656 larvae were collected, being 162 Liogenys fuscus, 120 Cyclocephala verticalis, 37 Cyclocephala forsteri, and 2337 Anomonyx sp. In... |

| Arcelin is a seed protein found in wild beans (Phaseolus vulgaris) which gives resistance to Mexican bean weevil, Zabrotes subfasciatus (Boheman 1833) (Coleoptera: Bruchidae). Studies were carried out with the objective of estimating the effect of four alleles of protein arcelin (Arc1, Arc2, Arc3 and Arc4) on the biology of Z. subfasciatus. The experiment was carried out in laboratory at Embrapa-Centro Nacional de Pesquisa de Arroz e Feijão, in Santo Antônio de Goiás, GO, Brazil, under non controlled conditions. The highest levels of antibiosis to Z. subfasciatus were observed in Arc1, with reduction in the number of eggs, number of emerged adults, adults longevity. In the line Arc2 only reduction in the number of emerged adults was observed. The lines... |
