Extract

The length of the developmental period from oviposition to adult emergence for nondiapausing individuals of a solitary endophagous braconid, Microctonus vittatae Mues., was usually about 4 wk at 20°C, 70–80% R.H., and a 16h:8h L:D cycle. However, living second and subsequent instar parasite larvae were occasionally found in adults of Phyllotreta cruciferae (Goeze) and Phyllotreta striolata (F.) (Coleoptera: Chrysomelidae) dissected 25–30 days after parasitization. Most of these beetles also contained one or more dead parasite eggs or first-instar larvae, suggesting that superparasitism prolonged development of the single surviving parasite in each host. Therefore, the effect of superparasitism on the parasite's development was investigated by recording the length of the developmental period of M. vittatae in two groups of adult P. cruciferae, one consisting of a majority of superparasitized individuals and the other mostly of hosts with only one immature parasite each.
