Abstract

Syrphus ribesii is a widespread and very common species of subfamily syrphinae which its larvae are predator of a variety of aphids. Despite of its importance in biological control of aphids, informations on its biology and rearing techniques in Iran are little. Along with faunistic survey, its biology was investigated under standard laboratory conditions. Gravid females were obtained from the field and stock culture were raised in aluminium cages which their 3 sides and top were covered with muslin. The adults were fed with fresh pollen from aster flowers, sugar and water. Oviposition stimulated by introducing in the rearing cages cut branches of rose flower infested with rose aphid, Macrosiphum rosae. The females laid eggs on the cut branches of rose infested with aphids. To study the developmental period of different life stages, the cut sections of rose plant bearing the known aged eggs were removed into another rearing cage with the same laboratory conditions. Two days after hatching the eggs, the larvae were placed individually in plastic Petri dishes (diameter 14 cm, height 4.5 cm) and were fed daily with rose aphids collected from the field. Daily examinations were done 3 times (8 A.M., 12 A.M. and 6P.M.). Rearing procedure lasted for 3 months and by this way, the time taken by each stage to be completed, the average number of prey consumed during larval stage, total eggs laid by each female and some other characters were determined. Under laboratory conditions, one generation of this predatory insect took 27.2 days to be completed. Also it was possible to rear this syrphid continusely. However, field sampling from larvae and adults showed that this syrphid has 2 generations as well as one incomplete one per year. The larvae of 3rd generation over winter under fallen leaves on the ground.
