Hilgardia, 1970, vol. 40, issue 10

Abstract: This study revealed that prey population attributes, not individual attributes, dictate the efficiency with which Metaseiulus occidentalis (Nesbitt) (Acarina: Phytoseiidae) responds to and controls populations of given spider mite species (Eotetranychus willamettei Ewing and Tetranychus pacificus McGregor) on grapevines.
