ROSE :: MAJOR PEST :: PESTS OF ROSE

3. Red spider mite: Tetranychus cinnabarinus (Tetranychidae: Acarina)
Damage symptoms :  Nymphs and adults feed on the undersurface of the leaves and are found covered with silken webs. As a result, yellow spots appear on the upper surface, which gradually turn reddish. Affected leaves finally wither away. Growth and flower production are adversely affected.

Bionomics  : Both nymphs and adults are red in colour. About 200 whitish, spherical eggs laid on the ventral surface of the leaves and measure about 0.1 mm in diameter.  Egg period 4-7 days, larval and pupal periods 3-5 and 8-12 days respectively. Life cycle is completed in 15-20 days and there are 15 generations / year.
Management : Prefer Spinx and temptation  varieties as they are moderately susceptible
Avoid First Red as it is highly susceptible.
Remove and destroy the damaged leaves along with mites.
