The authors thought they had experienced everything that the sugar beet crop could throw at them from a pest point of view after almost 40 years of working with the sugar beet industry. It was therefore very exciting to be confronted with a highly unusual pest this summer, so unusual that its presence in high numbers causing significant damage to a sugar beet crop in Norfolk in August 2021, is the first record of such damage in the UK. The pest was the exotic tortoise beetle, Cassida nebulosa, which the sugar beet bible, Pests, Diseases and Disorders of Sugar Beet, published by the International Institute de la Recherches Betteraves (IIRB), describes as rare, and never important in northern Europe. Indeed, this species has never, in our memory, been recorded before as a pest in sugar beet in the UK, only a very rare presence. Dewar and Cooke (2006) stated in their review of pest problems in sugar beet the UK, that crop damage by tortoise beetles never occurs in western Europe, but can be severe in warmer Mediterranean regions and in Russia.

Root Maggot

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.
