Abstract
Captures of diamondback moth (DBM), Plutella xylostella (L.), with different lures and trap designs were assessed in Hanoi, Vietnam. The lures in plastic basin traps with water containing detergent (5‰) had the most captures. Both Chinese lures and Japanese lures could effectively attract DBM males from January to May in 2002. The effective period of Chinese lures and Japanese lures was 30 days, during which time the captures of the two types of lures were not significantly different. Mass trapping of DBM with Chinese lures in plastic basin traps and BT (Bacillus thuringiensis) applications in cabbage or kohlrabi fields could decrease the population densities of DBM.
