Spider mite has been a major pest of greenhouse crops worldwide. They are<br />

common pest of Solanaeae (eg. peppers and tomatoes) and ornamental<br />

cultivars (eg. roses). The study on effect of spider mite feeding on Malaysian<br />

crops and ornamental cultivars are still lacking. Therefore, this study was<br />

conducted to determine the effect of spider mite feeds on leaves from different<br />

plants. The spider mites used in this study are Tetranychus cinnabarinus. Spider<br />

mites were collected from roses around district of Kuala Nerus, Terengganu.<br />

The leaves were left for spider mite infestation for four days. The feeding effect<br />

of spider mites were quantified based on the silver leaf spot area in (cm²).<br />

Total damaged area on roses was higher than chili and eggplant and the lowest<br />

total damaged area was eggplants. Therefore, the infestation of spider mite on<br />

leaves was different between host plants. The result from this study will provide<br />

the knowledge about the potential of spider mites can infest on host plants.<br />
