Relation between population density of the rice bug, Leptocorisa oratorius Fabricius (Heteroptera: Alydidae), and damage of rice grains



Relation between population density of the rice bug, Leptocorisa oratorius Fabricius (Heteroptera: Alydidae), and damage of rice grains



JIRCAS Journal ( 2): 59-64



Grain damage caused by the coreid Leptocorisa oratorius was investigated in relation to the insect population density in rice fields in Sri Lanka in 1989. The insect populations on rice plants at the time of flowering included a smaller proportion of nymphs in paddy fields with early flowering plants, but a larger proportion of nymphs in the fields where rice flowered later.
