Estudo do desenvolvimento pós-embrionário de stenomicra sp. n. (diptera: aulacigastridae) e o levantamento da dipterofauna imatura de heliconia sp. (musaceae).

Abstract

The genus Stenomicra comprises a poorly studied group of diptera. Adults were observed flying over the spiral foliage of Heliconia sp., which according to the rainfall may constitute a very efficient microhabitat for the life cycle of many individuals. The objective of this work is the description of the larval stages of a new species of Aulacigastridae found in this environment, as well as the survey of immature forms of other diptera. The work is concentrated in the Mocambo area, which is a terra firme forest reserve located on the outskirts of Belém. The still spiral leaves are packed in numbered plastic bags and their contents placed in containers with the same numbering. In the laboratory, individual observations of the leaves and their contents are made using a stereoscopic microscope. All Stenomicra sp. larvae found were last stage. Regarding the survey of other immature diptera, besides Aulacigastridae, the family Ceratopogonidae was also identified.
