ABSTRACT. Seasonality of three species ofSyrphidae (Insecta, Diptera) collected with Malaise traps in Parana State, Brazil. The project "Survey of the Entomological Fauna in Parana" (PROFAUPAR) was carried out in eight localities of Parana, Brazil, during two years. In the first year a total of 1.607 specimens of Syrphidae were collected with Malaise trap. The species Toxomerus tibicen (Wiedemann, 1830), Microdon mitis Curran, 1940 and Leucopodella gracilis (Williston, 1891) were the most abundant. The abundance and seasonality of each species are evaluated.

ABSTRACT. Survival analysis and estimation of entropy of Sareonesia eh/orogaster (Wiedemann) (Diptera, Calliphoridae). The life expectancy of Sareonesia eh/orogaster (Wiedemann, 1830) reared in at1ificial diet and controlled temperatures chamber set at 27± 1 °C, 70± 10% RH and 12 hours of photophase was analysed using entropy (H). Entropy (H) was used to quantify the distribuition of deaths between ages and then quantity the impact of mortality on life expectancy. The entropy values obtained for males (H=0,245) and females (H=0,299) were intermediary between the theoretical values of H=0,5 and H=O suggesting a tendency toward rectangular distribuitions in both sexes. The effect of mortality across ali ages on expectation of life was different at each age. For males the highest values were found between days 10 and 20 and between days 15 and 25 for females. This tindings imply that small changes in female m0l1ality will have a gl'eatel' impact 011 female life expectancy than will have on male expectation of life. KEY WORDS. Diptera, Calliphoridae, Sareonesia ch/orogasler, entropy, life expectation, survivorship curves A família Calliphoridae agrupa várias espécies de importância médico-sanitária devido principalmente, aos hábitos alimentares extremamente variáveis e ao elevado grau de sinantropia que estas podem apresentar (ZUM PT 1965;GREENBERG 1971). (Wiedemann, 1830) é um califorídeo cuja distribuição no Brasil, restringe-se apenas aos estados da Região Sul (DEAR 1979; QUEIROZ et ai. 1985) e que devido a seus hábitos alimentares necrófagos (LOPES 1973), sua preferência por áreas urbanas e seu elevado grau de sinantropia (FERREIRA 1978), pode ser utilizada com indicadora do intervalo pós-morte em entomologia médico-criminal (MOURA et ai. 1997). Sarconesia chlorogasterPor ser uma espécie necrófaga, utilizando-se por conseguinte de recursos efêmeros e temporalmente irregulares, torna-se também um ótimo modelo para estudos de estrutura e dinâmica populacional. A estrutura de uma população tem sido descrita basicamente através da utilização de tabelas de vida, onde descreve-se detalhadamente a mortalidade dentro de cada idade específica (CAREY 1993). Tal procedimento é extremamente importante devido a mortalidade não ser igual em todas as idades (DEMPSTER 1975;KREBs 1994).

Durante dois anos de coleta (1986 a 1988) do Projeto de Levantamento da Fauna Entomológica do Paraná (PROFAUPAR) em oito localidades do Estado, foram coletados 3316 indivíduos da família Syrphidae, sendo 1607 no primeiro ano e 1709 no segundo. Cinco espécies (Toxomerus procrastinatus Metz, Toxomerus tibicen (Wiedemann), Microdon mitis Curran, Leucopodella gracilis (Williston) e Paramicrodon flukei (Curran) destacaram-se pelos níveis de abundância alcançados, num total de 1554 indivíduos. São discutidas as distribuições sazonais de abundância de cada uma destas espécies.

L1FE CVCLE OF SARCONESIA CHWRO(j,ISTER (WIEDEMANN) (DIPTERA, CALLlPIIORIDAE, TOXOTARSINA E), REARED UNDER LABORATORV CONDITIONS ON ARTIFICIAL DIET. Bionomic characteristics of Sarcollesia chlorogasler (Wiedemann, 1830) were obtained, rearing it with an artificial diet and a controlled temperature chamber set at 27± 1°C, 70± 1 0% RJ-I and 12 hours photophase. The duration of the whole evolulive cycle ofS. cholorogasler was about 19.61 days. The incubation period was the shortest (14.30 hours), the pupal one (pre-pupal and pupal together) was the longest (9.57 days), followed by the larval period that had about 9.44 days. A !ife table for immalure stages was done in order to obtain a survival curve. The average ofthe adults longevity was about 25.28 days. There is no statistical difference between lhe duration ofmale and fema le longevity. The duration ofthe periods ofpre-posture and posture were almost the sarne (8.41 and 10.96 days respectively), but the period of pos-posture was lhe shortesl (5.15 days). The life lab les for adults, males and females were also done and lhe survival curves were obtained. The results were similar tor both sexes. Through the life table of fertility the number of generations of S.chlorogasler was estimated to be 9.81 generations/year. The lemales had a high felt ility under the laboratory conditions used. KEY WORDS. Diptera, Calliphoridac, Sarcollesia cldorogasler, bionomics, artiticial diet Considerado o grupo mais generalizado dos Oestroidea (ROBACK 195 1), a família Calliphoridae compreende espécies tipicamente necrófagas e saprófagas, cujas larvas são os principais decompositores iniciais de matéria orgânica animal ou vegetal, ou são causadoras de miíases, acidentais ou obrigatórias, no homem ou animais (ZUMPT 1965;GREENBERG 1971; BAUMGARTNER & GREENBERG 1985).Do ponto de vista médico-sanitário há uma crescente preocupação epidemiológica com este grupo de insetos dada a sua grande capacidade de dispersão, elevada densidade populacional e diversificado hábito alimentar -variando desde fezes e excrementos, lixo residencial e hospitalar, até al imentos frescos -aliados ao alto grau de si nantropia e endofi li a, tornando-os potenciais transmissores de agentes enteropatogên icos ao homem e animais domésticos (

ABSTRACT. MORPIIOLOGICAL ANALYSIS OF IMMATURE STAGES OF (Wiedemann, 1830) were obtained rearing it on an artificial diet in a temperature controlled chamber set at 27± 1°C, 70± 10% RH and 12 hours photophase. The egg, three larval instars and puparium were described and illustrated together with the larval cephalopharyngeal skeleton. Some characters were studied, for the first time using lhe scanning electron microscopy.

An obituary, although written at a sad time, pays honor and respect to a dear family member, friend, and colleague. It is difficult to summarize the many accomplishments of Renato Contin Marinoni. He very closely followed the poet's observation "life is too short to be small." Renato (as we all called him) did not seek personal recognition. He "wore the uniform of his team". His commitments were firm, and closely following his devotion to family was his commitment to foster the Department of Zoology of the Universidade Federal do Paraná (UFPR). During his almost 50 years of professional life, Renato Contin Marinoni played a pivotal role in transforming the Department of Zoology into a renowned research center. His performance as an administrator and professor was always impeccable and constructive, leaving a profound and an indelible mark on his home institution. Renato was often viewed as a reserved, serious person by those who did not know him well. This superficial, first impression kept some students and professors at a distance. Those close to him, however, knew a quite different, friendly, open-hearted man. From a taxonomist's point of view, the latter characterizations were his diagnostic features, and they will never be forgotten.
