Yield and Milling Quality of Monon Wheat Damaged by Feeding of Cereal Leaf Beetle12

Abstract

Damage from feeding of larvae of the cereal leaf beetle, Oulema melanopus (L.), caused considerable losses in yield of grain from Monon wheat. No significant losses in protein content, pearling index, mill yield, and alkaline water retention capacity were noted. Loss in yield of grain is brought about by reductions in kernel number and kernel weight and presumably could range from 0 to 21.3 g per 100 heads, or 0 to 23%, dependent upon the amount of flag leaf surface consumed by the larvae.
