What are Thrips?

Thrips are small, minute insects that can be found on the leaves of your plants. They belong to Arthropod phylum and there are a variety of names that are given to this creature like, thunder flies, harvest bugs, and corn flies, etc.,

They are 1.5 to 3 mm long which is difficult to see with naked eyes, and they depend upon the plants for their life, they feed upon plant parts like flower leaves and pollens.

They have elongated bodies and two pairs of wings to fly. Female thrips can give birth to 15 generations in one single year.

Thrips are found mostly on the ground, leaves, and woods as they feed on the following things:

  • Plant parts and nutrients such as chloroplast
  • Crops
  • Pollen grains
  • Wasp and Mite eggs
  • Moths
  • Other thrips

There are more than 6,000 thrip species, but are hard to distinguish from each other because of their uncanny resemblance.

Thrips live among leaves and woods feeding on pollen. Thrips function as a predator for even other thrips and moths. The chloroplasts in the plant cells are consumed by these beings. Another source of food for the thrips are eggs laid by mites and pollen grains.

Thrips life cycle

The average lifetime of a thrip is one month during which it undergoes the following different stages of life-cycle: egg, larval, pre-pupal, pupal, and adult.

Thrips lay two to ten eggs per day which require an optimum temperature of 20⁰C, and suitable environmental conditions to develop properly into an adult thrip in 20 days.
