The present study evaluates the pathogenic efficacy of an entomopathogenic fungus, Metarhizium anisopliae s.l. (=M. anisopliae) against red spider mite, Oligonychus coffeae damaging tea plants. Laboratory studies revealed that M. was on O. and exhibited 78% mortality. Evaluation formulated 5% aqueous suspension (AS) (1000 ml containing 2 × 107 conidia/ml in 400 L water/ha) through micro-plot a ...

A laboratory trial evaluated four phytoseiid species for their potential as biological control agents of spruce spider mite, Oligonychus ununguis (Jacobi) (Acari: Tetranychidae). An augmentative biological control approach, using the predatory mites Neoseiulus fallacis Garman and Galendromus occidentalis Nesbitt (Acari: Phytoseiidae), was evaluated for reducing pest mite densities and injury, a...

The use of a standardized beat sampling method for estimating spruce spider mite, Oligonychus ununguis (Jacobi) (Acari: Tetranychidae), densities on a widely used evergreen ornamental plant species, Juniperus chinensis variety 'Sargentii' A. Henry (Cupressaceae), was examined. There was a significant positive relationship between total spruce spider mite densities and spider mite densities from...
