Different instar nymphs of Sogatella furcifera HORVATH, just after hatching or moulting, were immediately reared at 24℃ under 16-hour lighting after attack by Haplogonatopus apicalis R.C.L. PERKINS (=H. japonicus ESAKI et HASHIMOTO). When the parasite parasitized on each of the 1st-5th instar nymphs of hosts, the instar period of parasitized nymphal stage was prolonged, but that of the following nymphal stages after parasitization was not. When the 4th and 5th instar nymphs of host were parasitized by parasites, a small number of females after adult emergence were able to deposit their eggs. A fair number of males after adult emergence could reproduce themselves when the 3rd-5th instar nymphs were parasitized. When the parasites parasitized on the 1st-3rd instar nymphs of hosts, the progenies of parasites hatched from the dryinid sacs on the 5th instar nymphs and adults of host after they fully grew in the hosts. On the other hand, when they parasitized on the 4th and 5th instar nymphs of hosts, a large number of the progenies of parasites hatched from the dryinid sacs on the host adults. The parasite larvae which hatched from the dryinid sacs on host adults required more time for development than those from the 5th instar nymphs of hosts.
