Effectiveness of the combination of attractants and colors in trapping fruit flies [Bactrocera spp] on chili plant [Capsicum annuum L.]

Abstract

The research was carried out to examine the effect of attractants and the color of traps in trapping fruit flies [Bactrocera spp.]. The research was done by using Randomized Block Design [RBD] with 2 factors and 3 replications. The first factor was the type of attractants consisted of 3 levels; A0 [methyl eugenol + water], A1 [methyl eugenol + guava juice], and A2 [methyl eugenol + starfruit juice]. The second factor was the colors of trap consisted of 4 levels; B0 [without color [transparent]], B1 [red], B2 [yellow], and B3 [green]. The result shows that: trap A1B3 [methyl eugenol and guava juice as an attractant, green trap] was a type of trap that has the broadest spectrum to attract and trap various species of fruit flies. There was no significant effect of adding color to traps in attracting and trapping male fruit flies. Male fruit flies generally were more attracted and more trapped in traps with methyl eugenol as attractants than the traps added with fruit juice. Female fruit flies were attracted and trapped only in a trap with attractants containing fruit juice as an attractant.
