Insect pests on cruciferous crops and their natural enemies were surveyed during 2009~2011 in Daegwallyeong highland region which has been famous for summer Kimchi cabbage production in Korea since 1970s. Totally 15 insect pests have been reported in cabbage field in Daegwallyeong. Diamondback moth (DBM, Plutella xylostella) imported cabbage worm (Artogeia rapae L.), cabbage armyworm (CAW, Mamestra brassicae L.), cabbage looper (CL, Trichoplusia ni), cabbage sawfly (Athalia rosae ruficornis Jakovlev), and turnip aphid (Liphapis pseudobrassicae (Davis)) were the dominant pest species among the 15 species. For monitoring as well as controlling insects with weak flight, yellow sticky cards (10×15㎝) were used in cabbage fields. The sticky cards were hanged on plastic stick and placed at a 2-5 m distance within cabbage field (1,000㎡). Sex pheromone traps were employed for monitoring and controlling insects with strong flight. The survey result showed that there was significantly reduced pest occurrences in treated, compared to untreated condition. Similarly, The results from the sex pheromone traps were coincident with those of sticky trap. DBM, CAW and CL were found less in the treated than untreated fields; by 67.5%, 70.6% and 44.0%, respectively. Although the control efficacy of such traps was less than that of chemical spray, the use of sticky card trap combined with sex pheromone trap could be useful management tools for controlling insect pests in cabbage fields.
