Social context during ontogeny affects cannibalism and kin recognition of the predatory mite Amblyseius herbicolus at different life stages
Cannibalism is commonly found among phytoseiids at almost all mobile life stages. The avoidance of kin cannibalism in the presence of non-kin has been observed in a limited number of phytoseiid species. Howeve...
