| Biological characteristics of Nipteria panacea Thierry-Mieg (Lepidoptera, Geometridae), an avocado tree defoliator, in highlands areas of Espírito Santo, Brazil. The objective of this research was to evaluate some biological characteristics of the avocado tree defoliator, Nipteria panacea Thiery-Mieg, in laboratory. This species showed the mean development cycle of 58.1 days, embryonic period of eight days and egg viability 56.3%. Pos-embryonic development lasted 36.5 days with viability of 48.2%, pupal period 11.6 days with viability of 76.0%, and mean longevity of females was 19.5 days with a production of 177 eggs per female. Other parameters were also observed and discussed. |

| NOAA’s National Marine Fisheries Services (NMFS) received a petition to list the Eastern oyster (Crassostrea virginica) as either threatened or endangered under the Endangered Species Act (ESA). The Eastern oyster is an emblematic species in the US coastal states, playing a significant role at various levels: shaping coastal social communities, providing a commercial activity (public fishery & aquaculture) and recreational - amenity benefits, and as a keystone species in highly diverse and sensitive ecosystems (estuaries). This petition is likely the result of concerns regarding the partial collapse of public fisheries in several states as well as from the resulting damages to this species induced by severe hurricanes. A Biological Review Team (BRT)... |

| A busca por informações sobre as espécies de cerambicídeos associadas à Ocotea puberula (Rich.) Nees (Lauraceae) em galhos cortados por Oncideres cervina Thomson, 1868 (Cerambycidae: Coleoptera), motivou o presente estudo. De 49 galhos cortados do hospedeiro na região central do estado do Rio Grande do Sul, determinou-se a emergência de cerambicídeos com avaliações bissemanais. Além de O. cervina, o serrador dos galhos, foram observadas três espécies de cerambicídeos, Trestonia capreola (Germar, 1824), Dihammaphora signaticollis Chevrolat, 1859 e Tropidozineus rotundicollis (Bates, 1863) (Cerambycidae: Coleoptera), sendo para duas o primeiro registro de planta hospedeira desta família botânica. O período de emergência dos cerambicídeos de galhos de O.... |

| In Brazilian Amazonia, Cholini (Coleoptera, Curculionidae, Molytinae) is represented by 53 species distributed in seven genera: Ameris Dejean, 1821; Cholus Germar, 1824; Homalinotus Sahlberg, 1823; Lobaspis Chevrolat, 1881; Odontoderes Sahlberg, 1823; Ozopherus Pascoe, 1872 and Rhinastus Schoenherr, 1825. This work documents the species of Cholini housed in the Invertebrate Collection of the Instituto Nacional de Pesquisas da Amazônia, Manaus, Brazil and gives the geographical and biological data associated with them. A total of 186 Cholini specimens were identified as belonging to 14 species (13 from Brazilian Amazonia) and five genera (Cholus, Homalinotus, Odontoderes, Ozopherus and Rhinastus). Only 24% of the Cholini species reported from Brazilian... |

| Calacarus heveae Feres, 1992 is an Eriophyidae mite described from rubber tree (Hevea brasiliensis Muell. Arg.) in the northwest region of the State of São Paulo. This mite prefers the adaxial face of the folioles and it can reduce the brightness of the leaves, turning them progressively yellow and brownish, and consequently premature fall. The aim of this work was to study the biology of C. heveae in laboratory, on detached rubber tree folioles. The study was conducted at 28±1 ºC in the photophase (12h), 25±1 ºC in the dark phase (12h), and 90±5% relative humidity. The study was initiated with a total of 59 eggs. The average duration of egg, larva and nymph stages was 5.8, 2.0 and 1.4 days, respectively. The period from egg to adult lasted 9.3 days, and... |

| The nesting behaviour of the solitary wasp Tachysphex inconspicuus (Kirby) was comparatively studied based on observations made in two environmentally distinct locations in southeast Brazil: upper portions of two sandy beaches and a dirt road in a forested area. Motor patterns related to nest construction were similar in all observed wasps, but some behavioural features, which were different among the observed wasps in the two environments, seem to be constrained by ecological factors. T. inconspicuus can be behaviourally differentiated from several other species of the genus by the following combination of features: they close the nest temporarily during its provision, do not let the excavated sand to form into a mound in front of the nest entrance,... |

| Nymphs and adults of Tingis americana Drake, 1922 were found feeding on leaves of Handroanthus heptaphyllus (Vell.) Mattos and Handroanthus chrysotrichus (Mart. ex A. DC.) Mattos in the Botanic Garden, Porto Alegre, state of Rio Grande do Sul, Brazil. This is the first record of T. americana on these host plants and in the southern Brazil. We aimed to compare the nymphal development on both hosts and to analyze the reproductive parameters on H. heptaphyllus (25 ± 1ºC; 60 ± 10% RH; 16 h photophase). The mean nymphal period (days) was shorter in individuals reared on H. heptaphyllus (12.69 ± 0.076) than on H. chrysotrichus (19.11 ± 0.208) (P < 0.0001), however, nymph viability was similar. On H. heptaphyllus, the mean embryonic period lasted 12.32 ± 0.274... |

| ABSTRACT: Given the increasing importance of Elaphria agrotina (Guenée) (Lepidoptera: Noctuidae) in corn crops, especially in the Brazilian Savannah biome, the present research aimed to study its development and survival on Greene’s and Poitout & Bues’s artificial diets (25±1°C, 70±10% relative humidity [RH] and 12h photophase). Poitout & Bues’s diet was more suitable than Greene’s diet, providing higher survival percent (77.51% vs. 5.57%), lower development time (49.81 days vs. 55.24 days) and higher fecundity (167.65 vs. 84.9 eggs), respectively. All the caterpillars reared on Poitout & Bues’s diet passed through six instars, while almost half of the larvae reared on Greene’s diet went through one less instar stage. Regarding the main... |

| Discusses concepts of competition in economics and ecology and the relevance of evolution to both subjects. It is suggested that although speciation or increasing biodiversity tends to occur in undisturbed ecological systems, the opposite trend may occur in economic systems. Competition based on optimisation plays a significant role in theories of the evolution of species and some theories of the evolution of business or industrial structures. But evolution does not result in optimal selection of species or businesses for the future, and there is scope for doubt about what is being optimised by survivors in the evolutionary process. Ecological or biological theories of intra-specific competition involving scramble and contest competition are outlined and... |
