attack on rice crop

Rice Leafroller or Leaf folder is supposed to lay egg in single or in groups in longitudinal path whereas yellow stem borer lays in clusters called egg mass. Please review in my picture. The moth is very active, bright yellow or straw in colour with two distinct wavy lines in the fore wing and one wavy distinct line in the hind wing. It has a wing span of 15mm. Eggs are laid singly or in groups arranged in longitudinal rows on the undersurface of the leaves which are scaly white in color. Fecundity is about 56 eggs. Incubation period is 4–8 days. We find 5–6 larval instars, larval period is about 22–23 days. It pupates with in the infested leaf fold for a period of 6–7 days. The fully grown caterpillar is green in color and is 16.5mm long. The total life cycle completed in about 5 weeks. So, andi, you can ck egg mass also for Yellow Stem Borer in my post below. Thank you!
