Abstract

A laboratory technique for mass-rearing the truncate spider mite, Tetranychus truncatus Ehara, is presented. This is an output of the project entitled "Survey, biology and mass-rearing of common phytoseiid predators of ornamental mite pests," funded by the DA-BAR from July 2001 to June 2004. The technique is simple and convenient. It uses waterlily, Eichornia crassipes L., as oviposition substrate and feed, plastic bucket for holding the waterlily plants; rectangular plastic vats as moats; and tap water to keep the waterlily plants fresh. An average of 4,162 eggs, 1,414 active stages, 1,003 female adults and 200 male adults per leaf can be produced after two weeks of continuous rearing on waterlily.
