The ontogeny and larval development of Aphidius suspensus was carried out under laboratory conditions during 1996. In this investigation electronic microscope (scanning) was used and developmental stages of about 100 samples, photographed. These studies show that, the eggs are ovoid without
terminal prosessus or stalk, about 0.235 mm length, 0.115 mm width larvae hymenopteriform with 14 segments, 0.57 mm length, 0.24 mm width, the
widest part of body is mesothorax, mandibles falciform and dorsal parts of body segments are covered with thorn like setae. First instar larval period is
about 70 hours. The second instar larvae is about 0.79 mm length, 0.30 mm width without mandible hut with a row of setae, one on each segment along
the body. Duration of this stage is about 33 hours. The third instar larvae is about 1.25 mm length and 0.54 mm width, mandibles visible, with transverse furrows on each dorsal segment spiracles visible. Third instar larval period is
about 35 hours. The fourth larvae is about 1.7 mm length and 0.65 mm width, with cylindrical body shape and distinct dorsal line on thorax and abdomen.
On head capsule antennae and mouth parts with different types of setae, papilles, mouth parts include, lahro - clypeus, mandibles, maxillae and labium. On the body and fine pubescents on caudus. Two types of caudal furrow
vertical and transverse are visible. This stage dures about 72 hours. Nymphal period is about 72 hours. Complete life cycle from eggs to adults under laboratory conditions is about 14 days.
