Life cycle: How spider mites grow?

 

Spider mites are very prolific in nature.  They get sexual maturity as little as 5 days, hatch within 3 days, and complete their lifecycle within 2-4 weeks. They undergo five stages of life –

  • Egg: Adult mites thrive during summer. Under optimal conditions, one female adult can lay 100-300 eggs (depending on species) within her 3-4 weeks’ lifetime. They usually lay eggs on the underside of leaves.
  • Larva stage: From the hatched eggs, eight-legged, translucent larvae expose. They start feeding plant fluids and grow fast. Then comes the nymphal phase: this phase undergoes two consecutive stages; Protonymph and Deutonymph.
  • Protonymph: In this stage, the larvae form eight legs, consume enough plant fluids, and stay inactive.
  • Deutonymph: After a moulting process, they transform into a deutonymph. This is another resting period.
  • Adult stage: The deutonymph moults further, changes in colour and shape, and becomes adult in a short time. Adults mature within five days and start to lay eggs. Unfertilized eggs produce males, and fertilized eggs produce female spider mites.
