Rice Bug (Walang sangit)

23 March 2022
5 mins read

Leptocorisa oratorius (Fabricius), or rice bug, is a common pest that damages rice grains during the ripening phase. The mechanism of damage is sucking grain grains that are filling. When disturbed, insects will defend themselves by emitting a smell. Apart from being a self-defense mechanism, the scent released is also used to attract other bugs of the same species. Rice bug damages the plant when it reaches the flowering phase until the milk matures. The damage causes the rice to change color and calcify, and the grain becomes empty. This pest can be controlled through several steps, such as:

  • control weeds, both in the fields and around the crops
  • Level the land well and fertilize plants evenly so that the plants grow uniformly;
  • Catching bugs using nets before flowering stage;
  • Feeding bugs with rotten fish, spoiled meat, or chicken manure;

Use insecticides when necessary and preferably in the morning or evening when the bug is in the canopy. The use of insecticides (if needed) includes the active ingredients:

  • BPMC,
  • fipronil,
  • metholcarb,
  • MIPC, or
  • propoxur.
