The authors explore the role of multiple predators on the transient and long-term dynamic outcomes of biological control. Theory indicates that specialist predators ought to promote less stable long-term biological control than generalists, while generalists readily drive suppression of nontarget prey species. However, these results showed that the combination of specialists and generalists acted synergistically to promote safe biological control. The results also suggested that endemic generalist predators, not introduced generalist predators, may often be responsible for the suppression and elimination of nontarget species. This final result demands empirical attention.

Over 100 investigations have utilized gut-content analysis to estimate aphid predation rates by predators including gut dissection, radio-labelling of prey, dissection of faecal samples, electrophoresis, stable isotope analysis and use of polyclonal antisera, monoclonal antibodies. Advances in molecular biology have enabled the detection of species-specific DNA sequences and use of these applications to quantify predation by aphidophagous predators is reviewed.

More success for IBCAs has been achieved with seasonal inoculative releases (50.0% of cases) than for classical biological control programs (17.1% of cases). Concerns about potential non-target effects but post-release evaluation has often been insufficient to draw any conclusions about them. Most of the biological control agents introduced in Spain were parasitoids (n = 53), and the remainder predators (n = 12). Only four parasitoids are considered monophagous. Using information from literature and the internet, the mean number of host species parasitized by parasitoids is 15.2, Therefore, polyphagy appears to be quite common among the IBCAs that have been introduced in Spain.

This issue contains 7 papers focusing on the importance of Heteropteran predators as biological control agents. The ecology and risks and benefits of using these predators in insect pest and weed control are also discussed.
