The biology of the black bug, Scotinophara coarctata, was determined in laboratory and field experiments in Palawan Island, Philippines. The egg guarding behavior of the female deterred the full impact of the indigenous egg parasite, Telenomus triptus. Raising the water to a level higher than the egg masses drives the female black bug off the mass and also results in reduced egg hatch. Implications of using water level for black bug control were discussed.
