Lygus bugs, which are among the most destructive insect pests in the western United States where they attack a wide variey of crops, are important in Arizona because they attack cotton, alfalfa grown for seed, and safflower. The most abundant of the 3 species of Lygus present in southern Arizona and Californa is L. hesperus Knight (Stitt 1940). Therefore, the effect of temperature on the development of L. hesperus was studied (Champlain and Butler 1967; Butler and Wardecker, unpublished data). Also, the effect of temperature on the development of the 2nd species, the tarnished plant bug, L. lineolaris (Palisot de Beauvois), was studied by Ridgway and Gyrisco (1960) and by Bariola. The 3rd species, L. desertus Knight, described in 1944 from specimens collected at Ajo but present throughout Arizona, is the least abundant of the 3 in the principal agricultural areas. Its development in relation to temperature has not been previously reported, though some references in the literature to L. elisus Van Duzee (such as Stitt 1940) undoubtedly refer to this species.
