Cultivar Response to Wheat Strawworm¹

A survey of six Ellis county Kansas wheat (Triticum aestiuum L. em. Thell.) fields in 1979 indicated that 53% of culms were infested with larvae of the second generation wheat strawworm, Harmolita grandis (Riley) form grandis. Early maturing cultivars tended to escape infestation in cultivar yield trials at Hays, Kans. in 1979. However, ‘Centurk’, ‘Centurk 78’, ‘Rocky’, and ‘Parker’ cultivars had lower infestations than others of the same maturity class, indicating possible cultivar resistance. Yield losses of 6 to 10 % were recorded for ‘Sage’ wheat culms infested with form grandis in 1979 and 1980. These losses, combined with the more serious damage reported for the spring form minuta, indicate this pest should be monitored more accurately, since moderate wheat strawworm damage may go unnoticed or credited to other insects.
