The Effects of Swathing on the Survival of Nymphs of Lygus lineolaris L. (Heteroptera: Miridae) in Canola

摘要: Cutting canola and placing it into swaths had both immediate long term effects on plant bug populations. About one-half of the nymphs were dislodged from crop when was cut. Whether displaced moved to swath or not depended age stage Very few crops cut 30-40% seeds begun ripen but many if at an earlier stage. Older readily fed reached adulthood swathed fewer young completed their development than standing crops. As a result populations decreased more rapidly The likelihood that swathing could reduce feeding damage in is discussed.
