The present work was carried out to investigate first, the ecology of the Sepedon flies as well as speciesof Lymnea snails and secondly, the biological effects of Sepedon fly larvae living on Lymnea. In this regard,the life cycle, death rate and compatibility of Lymnea species, as well as the life cycle of Sepedon flies inbreeding cage and the activity of the new larvae in the same ecological c...

the paper contains the first report on the biology of snail-killing flies (sciomyzidae) in khuzestan. it is based on field and laboratory studies conducted during november 1971 and april 1973, as well as field observations in may 1972, at the dezful medical research station. additional biological information obtained during studies is given for pherbellia fuscipes (macaquart), p.grisescens (mei...

The type specimens of Tenthredo sensu lato deposited in the Hungarian Natural History Museum (Budapest) are reviewed. The following synonyms are recognized and discussed: Rhogogastera aenescens Mocsáry, 1909, syn. nov. of Tenthredo (Temuledo) finschi finschi W.F. Kirby, 1882; Macrophya prasinipes Konow, 1891, syn. nov. of Macrophya caucasica (Mocsáry, 1880); Tenthredo concinnoides Malaise, 1945...

the following three procedures have been used to determine the sex ratio of s.sphegea. the fly is one of the two iranian species of the genus sepedon which is fairly dominant in the focus area of schistosomiasis in khuzestan (south of iran) and by far abundant in the provinces of gilan and mazandaran, north of the country. a) collection of adults in late summer of 1975, about 200 adults s.spheg...

the biology of immature stages of s.sphegea and different techniques for their laboratory rearing has been studied during the past five years (1972-77). this fly is one of the 18 iranian species of snail-killing flies which is dominant in the focus area of schistosomiasis (khuzestan province) in the south-west of iran. the following procedures improved appreciably our laboratory rearin-technics...
