Abstract:

Infestation of dry-farm wheat during 1931 by the second brood of the wheat strawworm, Harmolita grandis (Riley), was considerably lower, and that of irrigated wheat but slightly reduced as compared with conditions during the preceding year. During 1931 the wheat jointworm, H. tritici (Fitch), was found infesting wheat in three Utah areas, the principal injury occurring in the Tooele-Lake Point section. The rye strawworm, H. websteri (Howard), is frequently encountered in rye-growing areas of northern Utah, being more generally distributed than the rye jointworm, H. secalis Fitch.
