[Development of formulations of sex attractant litchi fruit borer, Conopomorpha sinensis]
Plant Protection Bulletin (Taipei) 48 (3), 189-202
Abstract: Several different formulations were developed for attracting litchi fruit borer (LFB), Conopomorpha sinensis, based on five sex pheromone components of closely related cocoa pod borer, Conopomorpha cramerella. These five sex pheromone components of cocoa pod borer were as following: I, E,Z,Z-4,6,10-hexadecatrienyl acetate (E,Z,Z-4,6, 10-16:Ac), II, E,E,Z-4,6,10-hexadecatrienyl acetate (E,E,Z-4,6,10-16:Ac), III, E,Z,Z-4,6, 10-hexadecatrieny-1-ol (E,Z,Z-4,6,10-16:OH), IV, E,E,Z-4,6,10- hexadecatrien-1-ol (E,E,Z-4,6,10-16:OH), and V, n-hexadecyl alcohol (16:OH). Attractiveness of the formulations to litchi fruit borer was tested in laboratory with the turntable method and in the field. The results showed that component I/II mixed with different ratios of III/IV significantly increased attractiveness of formulations to LFB, while only component I/II=35-97/65-3 or III/IV=97.5-50/2.5-50 did not show attractiveness. The formulas I/II/III/IV/V=65/35/35/15/0, 92/8/46/4/0, 100/0/15/10/0, 92/8/4/6/10, 92/8/46/4/100 were more attractive than other formulas to LFB, and component II reduced attractiveness of sex attractant formulas to LFB. The formulas with 0.1 mg attractant components in microtube were more attractive to LFB and cheaper than other formulation designs when we compared attractiveness of formulas with 5 different carriers and different dosages of lure.
