Natural History, Ecology, and Management of Diamondback Moth (Lepidoptera: Plutellidae), With Emphasis on the United States

摘要: Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), has become the most destructive insect pest of cruciferous vegetables ( Brassica oleracea L.) worldwide, and is a continuing problem especially in southern United States. Because inconsistencies individual control methods, inefficiencies time demands scouting, lack clear thresholds, current management practices emphasize prophylactic use insecticides. Numerous other methods are available for P. including host plant resistance, biological controls, cultural behavioral management, judicious Past experience shown that alone, none these strategies will work sufficiently insecticide misuse resistance issues likely continue. However, when used together, tactics can complement each lead to more sustainable system. Recent research focused on molecular genetics genomics dramatically increased our understanding specific mechanisms controlling physiology its interactions with plants. This potential revolutionize way we manage this pest. Here summarize natural history ecology diamondback moth present options sampling management. Additionally, highlight recent may integrated approach managing suite pests crops.
