Desenvolvimento de Synthesiomyia nudiseta (Diptera, Muscidae) em laboratório

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 effect of environment on development and survival of pupae of the necrophagous fly Ophyra albuquerquei Lopes (Diptera, Muscidae)

The effect of environment on development and survival of pupae of the necrophagous fly Ophyra albuquerquei Lopes (Diptera, Muscidae). Species of Ophyra Robineau-Desvoidy, 1830 are found in decomposing bodies, usually in fresh, bloated and decay stages. Ophyra albuquerquei Lopes, for example, can be found in animal carcasses. The influence of environmental factors has not been evaluated in puparia of O. albuquerquei. Thus, the focus of this work was motivated by the need for models to predict the development of a necrophagous insect as a function of abiotic factors. Colonies of O. albuquerquei were maintained in the laboratory to obtain pupae. On the tenth day of each month 200 pupae, divided equally into 10 glass jars, were exposed to the environment and checked daily for adult emergence of each sample. We concluded that the high survival rate observed suggested that the diets used for rearing the larvae and maintaining the adults were appropriate. Also, the data adjusted to robust generalized linear models and there were no interruptions of O. albuquerquei pupae development within the limits of temperatures studied in southern Rio Grande do Sul, given the high survival presented.
