Abstract
Studies of the effect on cotton yield of 2 levels of simulated Heliothis damage to squares and bolls were made at 2 locations in Mississippi between 1965 and 1967. Simulated larva damage at the level of 1 larva/5 feet and 1 larva/2½ feet did not cause a significant decrease in yield of seed cotton over the undamaged check. Yield of seed cotton was increased in some cases when the fruit was damaged early enough for the plant to compensate for the damage by producing new fruit.Keywords
