“…Much of the research in insect virology has been directed towards the use of viruses as field control agents for pest species, but it is unlikely that small RNA viruses will be used extensively for this purpose until more is known about their molecular biology, pathology and host range. A major problem regarding their potential use as insect control agents is created by several reported interactions between small RNA viruses of insects and antibodies in mammalian sera (Longworth et al, 1973b;MacCallum et al, 1979;Scotti & Longworth, 1980;Moore et al, 1981b). It is likely that inadequate monitoring of baculovirus preparations used in field control of pest insects has led to the accidental spread of small RNA viruses (Hess et al, 1977(Hess et al, , 1978.…”
