Oxysarcodexia Townsend, 1917 (Diptera: Sarcophagidae)-a centennial conspectus.

A taxonomic conspectus is presented for the genus Oxysarcodexia Townsend, 1917, which is one of the most species-rich genera of New World flesh flies. It has its center of diversity in the Neotropical Region, with some species reaching into the Nearctic and a few species introduced to the Australasian and Oceanian Regions. Species within this genus are primarily dung-breeders, but some species have also been bred from vertebrate carcasses.

Three new species of Oxysarcodexia Townsend (Diptera: Sarcophagidae)from the Colombian Andes.

Three new species of Oxysarcodexia Townsend (Diptera: Sarcophagidae) from the Colombian Andes are described based on male specimens collected using decaying animal matter as bait: Oxysarcodexia catica sp. n., O.

Rates of development of immatures of three species of Chrysomya (Diptera: Calliphoridae) reared in different types of animal tissues: implications for estimating the postmortem interval.

Blowflies have major medical and sanitary importance because they can be vectors of viruses, bacteria, and helminths and are also causative agents of myiasis. Also, these flies, especially those belonging to the genus Chrysomya, are among the first insects to arrive at carcasses and are therefore valuable in providing data for the estimation of the minimum postmortem interval (PMImin). The PMImin can be calculated by assessing the weight, length, or development stage of blowfly larvae.

[Population dynamics of Aedes aegypti (L) in an urban area with high incidence of dengue].

Aspects of the population dynamics of Aedes aegypti were investigated from collections over a two-year period in the urban area of Uberlândia, State of Minas Gerais. The population dynamics of this mosquito were influenced by physical factors such as temperature and rainfall. High larval densities also had an influence on mosquito development.
