| 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... |

| Se informa acerca de la lepidopterofauna diurna recolectada en el verano 2002-2003 en la Estación Biológica Senda Darwin, Chiloé. Se encontraron 9 especies: Eroessa chilensis (Guérin, 1830), Colias vauthierii Guérin, 1829, Nelia nemyroides (Blanchard, 1852), Auca coctei (Guérin, 1838), Homoeonympha humilis (C. & R. Felder, 1867), Hylephila signata (Blanchard, 1852), Butleria flavomaculata tristriata Bryk, 1944, Butleria elwesi Evans, 1939 y Butleria bissexguttata (Philippi, 1859), distribuidas en 3 familias: Pieridae, Nymphalidae y Hesperiidae. La mayor diversidad y homogeneidad se encuentra en los hábitats tipo pradera (H'= 1.59; J'= 0.99; 1-D= 0.79) y tipo bosque bajo y abierto (H'= 1.49; J'= 0.93; 1-D= 0.76), siendo el bosque cerrado el menos... |

| A field survey of flowering plants used as food resource by the adults of Heliconius erato phyllis (Fabricius, 1775) was carried out in four sites located in Rio Grande do Sul state, Brazil. Samples were taken in preserved areas of the Atlantic Rain and Myrtaceae forests, an Eucalyptus plantation, and an urban park. Adult feeding frequencies on flowers were registered monthly from December 1996 to May 1997, on plants located on previously marked 200 m long transects. Flowers on which H. erato phyllis fed in the field were collected, drawn and morphometrically characterized. Feeding was registered on flowers of twenty-three species, of which seventeen are new records for H. erato in Brazil . The use of a given plant varied among localities, as a function of... |

| The thermal requirements of Palmistichus elaeisis Delvare & LaSalle, 1993 were determined by rearing this pupal parasitoid in the following lepidopteran hosts: Diatraea saccharalis (Fabricius, 1794) (Crambidae), Anticarsia gemmatalis (Hübner, 1818), Heliothis virescens (Fabricius, 1777), Spodoptera frugiperda (J.E. Smith, 1797) (Noctuidae) and Thyrinteina arnobia (Stoll, 1782) (Geometridae). The experiment was set in laboratory conditions (temperatures between 18ºC and 30ºC, RH=70 ± 10% and 14-hour photoperiod). The life cycle (egg-adult) ranged from 40.4 ± 0.63 days (18ºC, H. virescens) to 18.1 ± 0.13 days (28ºC, D. saccharalis). The thermal constant of the egg-adult period ranged from 353.1 (D. saccharalis) to 407.7 degree-days (S. frugiperda).... |

| La más compleja de las interacciones que plantas e insectos han desarrollado durante el transcurso de su evolución, son las agallas. Las especies de insectos galícolas se encuentran en la mayoría de las regiones biogeográficas, principalmente en ambientes xéricos, de los cuales un ejemplo lo constituye la ecorregión del Espinal, ubicada en la Provincia Biogeográfica de la Pampa, Subregión Chaqueña. Schinus fasciculata (Griseb.) I.M. Johnst. (Anacardiaceae) es una especie arbórea o arbustiva representativa de la ecorregión del Espinal que presenta diversas agallas entomógenas. Los objetivos del presente trabajo son identificar las especies de insectos que producen agallas en hojas y tallos de Schinus fasciculata en un relicto de Espinal de la provincia de... |

| A demanda mundial por alimentos tem sido crescente com tendencias de continuar aumentando. O esforco para suprir essas demandas vem ocasionando o esgotamento acentuado dos recursos naturais. Por sua vez, tem havido em ambito mundial, mais conscientizacao sobre a necessidade de preservacao dos ambientes naturais. A resolucao dessa equacao (alta producao com baixo custo ambiental) e complexa, mas possível. Avancar na busca de respostas por meio do monitoramento da diversidade biologica e da composicao de especies de mariposas em projetos agricolas foi o objetivo central deste estudo. Os trabalhos forma realizados em Balsas, MA, durante os anos de 96,97, 98, 99, e 2000, utilizando-se de armadilhas luminosas. Ao todo, foram examinados 22.199 exemplares,... |
