| The activities of four colonies of Plebeia saiqui (Holmberg, 1903), of São Francisco de Paula, Rio Grande do Sul, Brazil, were studied from October, 1998 to September. 1999, comparatively during the oviposition period and the diapause. The construction of the cells was monitored by direct observation of the nests. The duration of the diapause period varied from 76 to 168 days. Monthly, the bees that left and entered were counted for 10 minutes, at each hour, during the complete period of flight activity. Influence of meteorological factors on the activities of bees flight was analyzed through simple and multiple regressions. During the oviposition period was found that solar irradiation, temperature and relative humidity had a significant influence on bees... |

| Five species of calliphorid flies, Chrysomya megacephala (Fabricius, 1794), C. putoria (Wiedemann, 1830), C. albiceps (Wiedemann. 1819), Cochliomyia macellaria (Fabricius, 1775) and Phaenicia eximia (Wiedemann, 1819), were collected hourly belween 6:00 and 18:00h., during five consecutive days per month for 12 moths; using home-made traps baited with rotting bovine lung. The data were statisticaly analyzed with relation to precipitation, temperature, relative humidity and luminosity. The results indicate that precipitation must have acted upon the seasonal abundance of the species, and that these responded equally to temperature, relative humidity and luminosity, throughout the entire day, except for P. eximia, which exhibited greater sensibility to these... |

| ABSTRACT Sphingidae attracted to light were systematically collected in an Amazonian forest canopy. Sampling occurred at a height of 34 m in an upland primary rainforest plateau in the Cueiras River basin, located within the Experimental Station of Tropical Silviculture, Manaus municipality, Amazonas, Brazil. The hawkmoths were collected using a vertical white sheet illuminated by a 250 W mixed mercury light and a 20 W black-light (BLB) fluorescent tube. Monthly collections were carried out from January to December 2004, during three nights of lunar transition from third quarter moon to new moon between 6 p.m. and 6 a.m. We sampled 1748 specimens, represented by 1485 males and 263 females, belonging to 52 species and 21 genera. Xylophanes comprised the... |

| ABSTRACT This study evaluated the influence of the environment and of two models of beehive (wooden box and ceramic pot) on the flight activity of the ground-nesting bee, Melipona quinquefasciata. The experiment took place in the Chapada do Araripe, in the State of Ceará, Brazil, between July 2014 and June 2015. The study followed colonies in three ceramic pots and four wooden boxes. Observations of the flight activity of the bees and of the climate were made on five days every month, each colony being monitored for 5 min, at intervals of one hour, from 0500 to 1700. The internal temperature and relative humidity of the hives were also recorded every hour throughout the year. The temperature correlated positively with the bees' entering and leaving the... |

| Flight activity of Melipona bicolor bicolor, coming from Cunha (23º05'S, 44º55'W), Atlantic Forest, was studied in ten colonies, and in two periods: from July to September 1993 and from August to September 1995. The colonies were grouped in weak, medium and strong, according to the diameter of the combs, which can provide a good idea of the number of cells built. 855 observations were accomplished for 5 minutes, every half-hour, from 8 to 18 hours. The total number of bees that entered and left the hive and the number of bees that arrived with mud, pollen and resin, besides the number that went out with debris in that period were counted. It was also registered the temperature and the relative humidity of the air. The total external activity, as well as... |

| Flight activity of Plebeia pugnax Moure (in litt.) was studied in six colonies coming from Cunha, SP, from July to October 1994. Twice a week, from 8:00 a.m. to 6:00 p.m., for 5 minutes every half-hour, all the bees entering and leaving the hives were counted. Six hundred counts were made and the materials that foragers carried were recorded. Data were analysed in relation to temperature, relative humidity, light intensity and day time. Foragers' flight activity was relatively constant in a wide range of temperature, from 22°C to 34°C. The minimum temperature for the beginning of flight activity was 14°C. Effective flight activity (when foragers of all colonies were leaving the hives) occurred at 15°C. These bees also flew within a wide range of relative... |
