Post-embryonic development and life table parameters of Neoseiulus californicus on Tetranychus desertorum and Panonychus citri (Acari: Phytoseiidae, Tetranychidae) under laboratory conditions
ABSTRACT The postembryonic development, and life table parameters of the Neoseiulus californicus were studied under laboratory conditions in order to evaluate the potentiality of this depredator for feeding on two phytophages mites Tetranychus desertorum (desert spider mite) and Panonychus citri (re...
