A Method of Rearing the Pale Western Cutworm, Agrotis orthogonia Morr. (Lepidoptera: Phalaenidae), in the Laboratory

Abstract
Methods of rearing various stages of the pale western cutworm, Agrotis orthogonia Morr., in the laboratory have been described (Hocking, 1952; Jacobson, 1952; King and Atkinson, 1927; Lindsay. 1954; Parker et al, 1921; Seamans and McMillan, 1935). From these a very satisfactory method has been evolved at the Lethbridge laboratory that this insect to be reared for several generations, providing a source of experimental material at any stage of development. The rearing may be done very satisfactorily a t room temperature but, if desired, the method is adaptable to rearing at various conditions of constant temperature and relative humidity.
