Kin recognition by cannibals is modulated by hunger level in a generalist predatory mite <i>Amblyseius herbicolus</i> (Chant) (Acari: Phytoseiidae)

Abstract Cannibalism is a commonly found behaviour in the animal kingdom. The biggest concern of cannibalism that it reduces inclusive fitness cannibals by eliminating close relatives. Kin recognition strategy used many to benefit from without cost reducing their eating Most members family Phytoseiidae are cannibalistic. Previous studies suggest specialist phytoseiids practice kin recognition, while generalists use species or discrimination due diet specification and frequent intraspecific interactions. We examined whether type‐III generalist phytoseiid, Amblyseius herbicolus (Chant) (Acari: Phytoseiidae). cannibalistic adults with different hunger levels (0‐, 24‐ 48‐hr starvation) were given choice non‐kin larva. A. was affected level. Adults not starved before test significantly preferred cannibalizing Conversely, for 24 48 hr showed no statistically significant preference between larvae. Furthermore, latency reflected level, where had most prolonged latency, intermediate shortest latency. This study suggests innate mechanisms avoid since larvae prior association experiment. effect familiarization on should be further investigated.
