    Abstract


    Five types of sex pheromone lures: Standard DJ- 2 mg (Z11-16Ald:Z9-16Ald) 3:1 ratio; Combined 1mg DJC - Z11-16Ac: Z13-18Ac 1:10 ratio and 1mg Z9-16ald: Z11-16Ald with 1:3 ratiol; DJZ1 - Z9-16:Ald (25 µg), Z11-16:Ald (75 µg) and Z9-18:Ald (12.5 µg); DJZ2- Z9-16:Ald (250 µg), Z11-16:Ald (750 µg) and Z9-18:Ald (125 µg) and DL - Z11-16:Ald: Z9-16:Ald with 2:1 ratio were tested in bottle trap design experiments conducted at Hanoi and Hai Phong. The experiment was arranged in a randomized complete block design with 5 replications. The distance between traps was 30m. The results showed that the average number of adult males caught in a trap per night was highest at the combined lure (DJC), followed by the standard lure (DJ) and the least was DJZ1 and DJZ2. Integrated effect of 4 components of the combined lure (DJC) showed the highest effect. Additional components (Z9-18L: Ald) compared with standard (DJ) has reduced the number of of adult males.
