Environmental impact of invertebrates for biological control of arthropods: methods and risk assessment.

Book cover for Environmental impact of invertebrates for biological control of arthropods: methods and risk assessment.

Description

This book, intended for the scientific community involved in biological control and integrated pest management, commercial companies producing biological control agents, risk assessors and regulatory authorities, compiles the current methodologies used for assessing the environmental impacts of invertebrate biological control agents and guidelines in performing science-based risk assessments requi...

Risks of interbreeding between species used in biological control and native species, and methods for evaluating their occurrence and impact.

Insect species introduced or augmented for biological control of insect pests may interbreed with native species, which may change fitness or cause evolution, which may in turn alter abundances. By 'interbreeding', we mean any reproductive interactions between species. We review the literature on factors affecting the likelihood of interbreeding between insect species and the impacts when these occur. We discuss phylogenetic relatedness, geographical distribution, spatial and temporal barriers to mating, mate recognition, copulation and sperm use, hybrid inviability and sterility, hybrid speciation, reproductive character displacement and introgression. We concentrate on the risks from introduced species, but we also address the risks from augmentation of native species. We propose methods for pre-introduction or pre-augmentation assessment of the likelihood and potential impact of interbreeding between native species and insects used in biological control. Finally, we propose methods for evaluating the occurrence and impact of interbreeding after insect species are introduced or augmented.
