What are the damage symptoms of thrips in carnation?

thrips

Thrips are damaging to carnation flowers in dry summer months. On coloured flowers they cause white flecks, but on white flowers they cause tan to brown specks. The western flower thrip, Frankliniella occidentalis, is the most prevalent thrip in Hawaii-grown carnations. Other species- e.g., Thrips palmi, T. tabaci, and T. hawaiiensis- are also common. The western flower thrip and T. palmi are the most difficult to control because they have developed resistance to insecticides. Adult western flower thrips, are about 1/20 inch long and are tan; the young are yellowish.

What are the damage symptoms of carnation bud mite?

carnation

Carnation bud rot in Hawaii is caused by saprophytic fungi and bacteria associated with the grass mite. Affected flower buds may appear normal on the outside, but the inner floral parts are discoloured light brown and moist in appearance. Interior petal decay occurs when fungi and bacteria associated with the mite invade the tissues damaged during feeding. With a magnifying glass, it is possible to see the white ellipsoidal bodies of pregnant female mites embedded in the discoloured tissue inside the bud. Young infected buds fail to open or open abnormally, generally in a lopsided way.
