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... |

Only seven types of mammals are known to be venomous, including slow lorises (Nycticebus spp.). Despite the evolutionary significance of this unique adaptation amongst Nycticebus, the structure and function of slow loris venom is only just beginning to be understood. Here we review what is known about the chemical structure of slow loris venom. Research on a handful of captive samples from three of eight slow loris species reveals that the protein within slow loris venom resembles the disulphide-bridged heterodimeric structure of Fel-d1, more commonly known as cat allergen. In a comparison of N. pygmaeus and N. coucang, 212 and 68 compounds were found, respectively. Venom is activated by combining the oil from the brachial arm gland with saliva, and can... |

The effects of larval crowding on survival, weight at metamorphosis and development time were assessed in the dengue mosquito, Aedes aegypti L., under a controlled environment. Larval cohorts were bred at 7 different densities (4, 8, 16, 32, 64, 128 and 256 larvae / 175 ml pot), while keeping constant water volume and food amount and quality, under controlled temperature and photoperiod. Natural detritus, mainly leaves, obtained from containers naturally colonized by A. aegypti, were used as a source of nutrients for larvae. Development time, mortality, mass at metamorphosis, and total biomass were recorded for each density. Development time ranged from 4 to 23 days in males, and from 5 to 24 in females, whereby larvae took longer to develop at 64... |
