Natural enemies

There are two types of natural enemies in the rice fields:

Predators

  • Captures, kill and eats the prey
  • eat many prey in a lifetime, feeding both as young and as adults
  • Usually larger than their prey
  • Do not have specific prey mostly
  • Some bugs, beetles, flies, lacewings and spiders

Parasitoids

  • Lay their eggs to other insects (the hosts).
  • Each egg hatches within the host, and the young feed and develop within that single host, eventually killing it.
  • Parasitoids are most commonly small wasps.
