	abstract = {From observations over a period of 7 years (1981-87), the seasonal incidence and voltinity of 37 species of Pipunculidae (which are parasitoids of Auchenorrhyncha) in Belgium is reported.Abstract 2: The annual modality of 37 Pipunculidae (Diptera) species occurring in Belgium is discussed. The results are based on data from 28 site-year cycles of Malaise traps (occasionally emergence and water traps) and material collected by handsweepings. Voltinism is detected and a seasonal sequence pattern is composed for the species discussed, showing a temporal distribution between univoltine and bivoltine species during the Summer. The results are compared with those from some other West and Central European countries. Intraspecific variability, probably caused by geographical as well as climatological differences, is discussed for some common species. Interspecific variability among closely related species is discussed as well as sex-ratios of the captures in the Malaise traps.},
