| To estimate the populational fluctuation of Chrysomya Robineau-Desvoidy, 1830 species and the relation of populational abundance around, six wind oriented trap (WOT) were placed in three distinct ecological areas (urban, rural and wild) in Pelotas, Rio Grande do Sul, Brazil, from February/1993 to January/1995. The flies were weekly collected. Captured species were Chrysomya albiceps Wiedmann, 1819, C. megacephala Fabricius, 1794 and C. putoria Wiedmann, 1830 with respective abundance of 64.5%, 19.7% and 0.9%, representing a total of 85.0% of 409,920 specimens of Calliphoridae. The three species demonstrated similarity in the populational fluctuation, except in the abundance. The populational peak ocurred in autum when the temperature decreases. In the... |

| Aspects related to the longevity and oviposition of Ophyra albuquerquei Lopes, 1985 are studied. Males had a mean lifespan longer than females (40.24 vs. 33.15 days, respectively), while still possessing qualitative advantages during this period. Females O. albuquerquei were fed on powdered milk, fish flour, refined sugar and water, and provided fish flour and moistened sawdust for oviposition. The length of the oviposition period for females was 46.75 days, and most of the deposition of the eggs occurred in the first days of the colony. Females completed 50% of their egg deposition by Day 16, seven days before the large last mortality peak and about 12 days after the first oviposition in the colony. Females deposited an average of 184 eggs per individual.... |

| A colony of Synthesiomyia nudiseta (WULP, 1883) was established in the laboratory to obtain eggs, larvae and puparium, to determine the period of development and viability at constant temperature with RH above 75% and photoperiod of 12 h. The viability of development cicle was 48.68%. Incubation period was 21.17 h, larvae development 25.97; 48.08 and 233.65 h for the first, second and feeding phase of third instars, respectively. The development period of postfeeding larva, prepupa and pupa development was 322.26 h. |

| The thermal requeriments of Culex quinquefasciatus (Say, 1823) and the number of generations in the year are determined. The colony to obtain eggs, larvae, pupae and adults was established under laboratory conditions. Every stage was maintained at constant temperature (15, 20, 25 and 30ºC), in cameras, with relative humidity of 80% ± 5 and photophase of 12 hours, to settle down the thermal inferior limit and the thermal constant by the method of the hiperbole. The thermal inferior limit to phase of egg, larvae and pupa were respectively 10.0, 9.1 and 10.2ºC, and 10.2ºC to all the aquatic cycle, with a thermal constant of 207.2 degree-day, with the mean of 15.5 generations per year in Pelotas, State of Rio Grande do Sul. |

| A reprodução e a sobrevivência de Synthesiomyia nudiseta (Wulp, 1883) foram estudadas entre 22 e 28ºC, UR de 70% e fotoperíodo de 12h. Os dados foram analisados através de classes de idade, tabelas de vida de fecundidade, análise de sobrevivência pela distribuição de Weibull e análise das curvas de sobrevivência através do conceito de entropia (H). A taxa intrínseca de aumento natural (r m), taxa finita de aumento (lambda), taxa de reprodução líquida (R0) e tempo médio de uma geração (T) foram 0,534; 1,7; 59,439 e 7,65 respectivamente, sugerindo rápido crescimento populacional nestas condições. Isso foi causado pela alta fecundidade, confirmando o que ocorre para esta espécie, com média de 266 ovos/fêmea e período de pré-oviposição de 10,25 dias. O modelo... |
