| Com o propósito de conhecer os parasitóides de cochonilhas e aleirodídeos, associados às plantas cítricas no Estado do Rio de Janeiro, foram realizadas coletas de folhas contendo os fitoparasitos: Aleurothrixus floccosus (Maskell), Tetraleurodes (=Aleurotrachelus) cruzi (Cassino), Paraleyrodes bondari Peracchi, Coccus viridis (Green), Crysomphalus ficus (Ashmead), Orthezia praelonga (Douglas) e Pinnaspis aspidistrae (Signoret), sendo estas limpas, em seguida procedia-se a eliminação dos organismo que eram objeto de estudo (cada folha permanecia com um única espécie de fitoparasito, para que os parasitóides que surgissem fossem mesmo associados àquela espécie). Após este procedimento as folhas foram incubadas por um período de 25 dias, onde foi observado... |

| We reviewed the theory of conservation genetics, with special emphasis on the influence of haplodiploidy and other aspects of bee biology upon conservation genetic parameters. We then investigated the possibility that pollinator decline can be addressed in this way, using two meta-analytical approaches on genetic data from the Hymenoptera and the Lepidoptera. First, we compared levels of heterozygosity between the orders. As has been found previously, the haplodiploid Hymenoptera had markedly lower levels of genetic variation than the Lepidoptera. Bees had even lower levels, and bumble bees, in particular, often seemed almost monomorphic genetically. However, the statistically confounding effects of phylogeny render detailed interpretation of such data... |

| For a study of diversity and genetic structuring in Melipona quadrifasciata, 61 colonies were collected in eight locations in the state of Minas Gerais, Brazil. By means of PCR analysis, 119 ISSR bands were obtained, 80 (68%) being polymorphic. He and H B were 0.20 and 0.16, respectively. Two large groups were obtained by the UPGMA method, one formed by individuals from Januária, Urucuia, Rio Vermelho and Caeté and the other by individuals from São João Del Rei, Barbacena, Ressaquinha and Cristiano Otoni. The Φst and θB values were 0.65 and 0.58, respectively, thereby indicating high population structuring. UPGMA grouping did not reveal genetic structuring of M. quadrifasciata in function of the tergite stripe pattern. The significant correlation between... |

| Diversas vespas parasitóides, especialmente Eulophidae e Chalcididae, têm sido registrados atuando sobre populações de Phyllocnistis citrella Stainton, 1856 (larva-minadora-dos-citros), uma das principais pragas da citricultura mundial. O presente trabalho objetivou identificar o complexo de parasitóides de P. citrella em dois pomares de citros situados em Montenegro, RS, um de tangerineira variedade Montenegrina e outro do híbrido tangor Murcott. Em amostragens quinzenais de julho de 2001 a junho de 2003, todos os brotos de plantas sorteadas aleatoriamente eram inspecionados. Todas as folhas com pupas de P. citrella foram coletadas e acondicionadas individualmente em placas de Petri até a emergência dos parasitóides ou dos adultos de P. citrella. No... |

| Os ninhos de Centris (Heterocentris) analis (Fabricius, 1804) foram estudados no Campus de Ribeirão Preto da Universidade de São Paulo, de janeiro a dezembro de 2003. As fêmeas nidificaram em ninhos-armadilha confeccionados com cartolina preta, os quais foram introduzidos em placas de madeira colocadas em duas áreas distintas: sombreada e ensolarada. Nas duas áreas, a mortalidade de imaturos ocorreu principalmente no estágio de ovo; área sombreada: estágio de ovo (76,7%), estágio de larva (10,0%) e estágio de pupa (13,3%); área ensolarada: estágio de ovo (80,0%), estágio de larva (6,6%) e estágio de pupa (13,3%). A diferença de mortalidade entre as duas áreas (chi2 = 1,0, gl:1, p>0,05) não foi estatisticamente significativa, entretanto, a diferença de... |

| AbstractHyaluronidases are enzymes that mainly degrade hyaluronan, the major glycosaminoglycan of the interstitial matrix. They are involved in several pathological and physiological activities including fertilization, wound healing, embryogenesis, angiogenesis, diffusion of toxins and drugs, metastasis, pneumonia, sepsis, bacteremia, meningitis, inflammation and allergy, among others. Hyaluronidases are widely distributed in nature and the enzymes from mammalian spermatozoa, lysosomes and animal venoms belong to the subclass EC 3.2.1.35. To date, only five three-dimensional structures for arthropod venom hyaluronidases (Apis mellifera and Vespula vulgaris) were determined. Additionally, there are four molecular models for hyaluronidases fromMesobuthus... |

| Crematogaster ants use their contact venoms to compete with other ants. Although those venoms are used primarily as repellent and toxic secretions, they may have other functions. The present study aimed to test the antibacterial property of abdominal venom of three neotropical Crematogaster ant species (C. distans, C. pygmaea and C. rochai) against gram-negative (Escherichia coli and Pseudomonas aeruginosa) and gram-positive (Enterococcus faecalis and Staphylococcus aureus) bacteria. Sterile filter paper was soaked with C. distans, C. pygmaea or C. rochai crude venom and placed on an agar dish that was inoculated with bacterial suspensions. The agar dish was incubated overnight at 37ºC and examined for zones of growth inhibition. For each tested venom and... |

| In true social hymenopterans, such as many species of bees, wasps and all species of ants, the main characteristics are the overlapping of generations, the care with the offspring and the division of labor among the members of the colony. The first biological feature means that in a same moment there are groups of individuals, with variable ages, that execute different activities in the colony. In order to study the division of labor among the members of the colony, or to estimate the life span of these insects, or even to analyze any kind of behavior in non-social insects, it is necessary to know the exact age of each individual. For this reason, the insects must be identified soon after emergence. The identification of insects with numbers is an... |
