QUALITY CONTROL OF Cochliomyia macellaria (FABRICIUS) (DIPTERA: CALLIPHORIDAE) IMATURES IN COLONY Quality control of Cochliomyia macellaria (Fabricius) (Diptera: Calliphoridae) larvae and pupae in colony was observed during eight consecutive generations. A diet consisting of decomposing horse flesh was used, and the relation of 0.02 g egg mass/ 200 g diet was established. The larval and pupal viability at 27 oC and 30 oC temperature, 65 <FONT FACE=Symbol>±</FONT> 10% UR and 14 h photofase, respectively, were greater than 80%. The egg to pupae period and the body mass of postfeeding larvae variation were 4.7-7.0 days and 59.40-70.30 mg, respectively. The emergence ocurred 8.0-12.0 days after the neolarvae innoculation in diet. The study has not show a linear relation between the analised characteristic and monitored generations

RESUMO O controle de qualidade de larvas e pupas de Cochliomyia macellaria (Fabricius) (Diptera: Calliphoridae), mantidas em estoques, foi monitorado durante oito gerações consecutivas. Uma dieta consistindo de carne eqüina putrefata foi utilizada, estabelecendo-se a relação de 0.02 g de massa de ovos / 200 g de dieta. A taxa de sobrevivência larval e pupal a 27 ºC e 30 ºC de temperatura, 65 <FONT FACE=Symbol>±</FONT> 10% UR e 14 h de fotofase, respectivamente, foi superior a 80%. O período de ovo a pupa e a massa corporal de larvas pós-alimentadas oscilou entre 4.7-7.0 dias e 59.40-70.30 mg, respectivamente. A emergência ocorreu 8.0-12.0 dias após a inoculação das neolarvas na dieta. O estudo não sugeriu uma relação linear entre as características analisadas e as gerações monitoradas.

In the present study we estimed the longevity and reproductive potential of Cochliomyia macellaria (Fabricius, 1775), in different densities of grouped pairs, as a function of time of collection. The study was divided into two phases and conducted in an incubator regulated at 27oC, 65±10% RH and 14 hours photoperiod. Forty and 20 pairs/replication were used, corresponding to the third and fourth generation originating from a laboratory colony. Egg masses were collected at 8:00 and 17:00 hours daily. The results obtained were influenced by the variables established. The ovipositing peak occurred 20 days after the emergence of females belonging to the third generation. This peak occurred earlier in fourth generation females, i.e., 11 days after imago emergence. These peaks corresponded to a total of 0,30 and 0,23g of egg masses, respectively. The survival curves for adults were estimated by the Weibull method.
