This mite is known as the pest of many crops, including cassava. <em>Neoseiulus longispinosus</em> Evans (Phytoseiidae) is a predatory mite commonly found on plant infested by kanzawa spider mite. This predatory mite has high potential to be developed as biological control agent of <em>T. kanzawai</em>. The aim of this research is to elucidate the effective density and release time of <em>N. longispinosus</em> to control <em>T. kanzawai</em> on cassava. The research was conducted in the greenhouse, using cassava of Mentega cultivar. <em>T. kanzawai</em> were introduced into the cassava plants two weeks after planting, with density 5 female adults/plants. <em>N. longispinosus</em> were introduced 1, 2, and 3 weeks after <em>T. kanzawai</em> introduction with predator:prey ratio of 0:5, 1:5, 2:5, dan 3:5, respectively. Population of <em>T. kanzawai</em> and <em>N. longispinosus, </em>and also plant damage were observed at 6 weeks after planting. <em>N. longispinosus</em> could suppress <em>T. kanzawai</em> population and the highest suppression occurred at the interaction between 3:5 ratio and the release time at one week after <em>T. kanzawai</em> infestation. There was no significant effect of <em>N. longispinosus</em> release at various release ratio and time on attack intensity of <em>T. kanzawai</em>.</p>}, number={3}, journal={Jurnal Entomologi Indonesia}, author={Putri, Nhyra Kamala and Nurmansyah, Ali and Santoso, Sugeng}, year={2021}, month={Dec.}, pages={207} }
