Spider mite is an economic plant pest that is affecting ornamental plants. The<br />

aim for this study to examine the survival rates of spider mites, T. cinnabarinus<br />

on rose leaves. Survival rate of T. cinnabarinus on rose leaves was evaluated<br />

in the laboratory at 26 o C and 41% relative humidity. Twenty adult female spider<br />

mites were transferred to the leaves in the tray. The female spider mite takes<br />

three days to lay eggs. Female laid eggs up to 118 and the eggs took one week<br />

to hatching and become larva. The development time from larva to nymph took<br />

from five to six days. This study is useful to predict the population growth rates<br />

of spider mites on rose leaves, thus may contribute in improving pest<br />

management of T. cinnabarinus in Malaysia.<br />
