The present situation with regard to the use of baculoviruses in insect control is outlined. By virtue of their high degree of host specificity, they offer considerable advantages over chemical insecticides, but their practical use is limited by a number of factors, particularly their slow speed of action. Various approaches to the genetic modification of baculoviruses to overcome these problems are described. These have resulted in improvements in insecticidal activity in laboratory trials which are now being confirmed in the field. Thus, genetically modified baculoviruses have a promising future in pest-control programmes. Our increasing knowledge of the genetic factors which regulate their behaviour is showing how other aspects of their performance may be controlled and exploited.
