Greathead, D.J., & Greathead, A.H. 1992 Biological control of insect pests by insect parasitoids and predators: the BIOCAT database.. Biocontrol News and Information 13(4): 61N-68N.
Notes: The structure of the BIOCAT database, which contains records of the introductions of insect natural enemies for the control of insect pests worldwide and is now available online, is explained. It is a useful summary of biological control effort and a guide to factors which may influence the success of introduction programmes, but is not detailed enough for making firm predictions. Scale species mentioned in this paper include Aspidiotus destructor, Phenacoccus manihoti, Pseudaulacaspis pentagona, Rastrococcus invadens and Unaspis citri.
