Abstract

Oviposition behavior may be affected by the presence of potential future

competitors, mates, or predators of offspring. We examined patch choice,

oviposition site preference and egg production in the predaceous mites Phytoseiulus

persimilis and Neoseiulus californicus (Acari: Phytoseiidae) when

given a choice between paired spider mite patches with and without conspecific

eggs, with and without heterospecific eggs, and with conspecific or

heterospecific eggs. Neoseiulus californicus females had no patch preference

and distributed their eggs randomly in all choice situations. This was also

the case with P. persimilis females given a choice between patches with and

without conspecific eggs and between patches with either con- or heterospecific

eggs. Phytoseiulus persimilis females confronted with patches with and

without heterospecific eggs preferentially stayed and oviposited in the predator

free patches. We discuss the oviposition strategies of P. persimilis and

N. californicus with respect to food competition, cannibalism and intraguild

predation.
