Thrip damage on the petals of dayliliesDescription of Thrips

Thrips are very small insects with a slender body. They are a common pest of garden plants and crop plants. The adult insect is less than 1/25th of an inch and either black or straw coloured. There are wingless as well as winged varieties.

What Do Thrips Eat?

They have asymmetrical mouth parts to extract the plant sap. One of the mandibles is a bit longer than the other. Apart from damaging the plant parts like leaves and buds by sucking the juice, they also lay eggs on fruits and leaves. This causes discolouration of fruits and leaves. Some thrips feed on the buds and leaves of the plant whereas there are varieties that feed on other insects by sucking the juice out of their body. Flower buds that die before opening and stippled leaves are an indication of thrips attack.

Lifecycle of Thrips

During the spring season, the female troops emerge from the pupal stage and start laying the eggs in the plant tissues of leaves, flowers and stems. Male insects are rare and are smaller than the female. They lay eggs without mating. Each female insect lays more than 80 eggs and it will get hatched within a few days in warmer climates. During cold weather, hatching will take weeks or months. The larvae emerging from the eggs are wingless and are called nymphs. They feed on the sap of the plant. After passing through 2 or more moulting stages, the thrips drop to the soil to start pupating. The pupae, as well as the adult insects, overwinter inside the soil. After pupation, the insect repeats the cycle. In a single year, more than 12 generations are produced. During warm weather, the life cycle requires only 16 days

Flower Damage By Thrips

Thrips cause cosmetic damage to the flowers. They can cause terrible damage to the flower petals of daylilies. The flowers of the woody plants like roses can also be affected by thrips attack. Dark streaks and spots may appear on the petals due to the feeding injury caused by thrips during the bud stage. Sometimes, the flower buds even fail to open due to the deformity caused by the insect attack. The mature and larval thrips feeds on the sap of the petals. Pictured is thrips inside the buds.
