Coccinellids have been widely used in biological control for over
a century, and the methods for using these predators have remained
virtually unchanged. The causes for the relatively low rates of
establishment of coccinellids in importation biological control have
not been examined for most species. Augmentative releases of several
coccinellid species are well documented and effective; however,
ineffective species continue to be used because of ease of
collection. For most agricultural systems, conservation techniques
for coccinellids are lacking, even though they are abundant in these
habitats. Evaluation techniques are available, but quantitative
assessments of the efficacy of coccinellids have not been done for
most species in most agricultural crops. Greater emphasis is needed
on evaluation, predator specificity, understanding colonization of
new environments, and assessment of community-level interactions to
maximize the use of coccinellids in biological control.
