Sugar beets are grown on approximately 38,000 acres of irrigated land in southern Alberta and their culture is a stabilizing influence on the economy of the irrigated districts. The sugar-beet root maggot, Tetanops myopaeformis (Röder), has been a pest of sugar heets in the sandy soil areas of southern Alberta since 1955 and caused serious damage in the same area from 1934 to 1937. This insect has been a problem also in Manitoba, North Dakota, Idaho, Montana, Wyoming, Utah, and Colorado (Allen et al., 1959; Callenbach et al., 1957; Hawley, 1922; Jones et al., 1952; Maxson, 1948). Considerable experimental work has been done on the control of this pest in Alberta (Harper et al., 1961a; Harper et al., 1961b; Lilly et al., 1961), but there have been no detailed studies published on the life history of the insect in Canada and there is very little information from elsewhere. In 1922 Hawley published notes on the biology of the insect in Utah. The present paper describes the life history of T. myopaeformis in southern Alberta.

The sugar-beet root magsot, Tetanops myopaeformis (Röder), is one of the most important pests of sugar-beets in southern Alberta. From 1956 to 1960 studies were made of various phases of its life history (unpublished). In this paper, napping adults of T. myopaeformis by insecticide and water traps is judged for reliahility in determining dates of emergence and sex ratio when compared with data obtained from emergence cages in the field. Information is also given on the influence of color and a wetting agent on the number of flies caught in water traps.

AbstractIn southern Alberta the fundatrix of P. betae hatches from the overwintered egg in late April and early May and feeds on an emerging leaf of P. angustifolia or P. balsamifera, forming a gall. In the gall it produces alate fundatrigeniae, which migrate from the poplars to beets and produce apterous alienicolae. This form of the aphid reduces both yield and sugar content of beet roots. During the summer several generations of alienicolae are produced. In the fall most of the alienicolae produce sexuparae. These migrate from beets to poplars, where they produce males and oviparae. Each fertilized ovipara lays a single egg on the bark of a poplar tree. The species may overwinter as eggs on the poplars or as alienicolae in the soil. The egg has an obligatory diapause that is terminated by exposure to low temperature. The fungatrigeniae migrate from late June to mid-August and the sexuparae from early September to late October. The potential reproductive capacities of the fundatrix, fundatrigenia, sexupara, and ovipara averaged 163, 13, 6, and 1, respectively. Under greenhouse conditions 20 aphids (alienicolae) produced 9,000 in 6 weeks when the soil temperature was maintained at 27 °C. Below 15 °C. the rate of reproduction was low and death was caused by exposure to 30 °C. for 6 weeks. The most important predators of P. betae were the anthocorid A. antevolens, the flies S. bigelowi, L. pemphigae and T. glabra, and a coccinellid Scymnus sp.
