Effect of Trap Height Level on The Capture of Fruit Fly (Bactrocera spp.) on Crystal Guava Field

Abstract

Fruit fly (Bactrocera spp.) is one of the most important pest of crystal guava. The use of bottle as a trap with methyl eugenol block (ME block) as an attractant is commonly applied to control the population of fruit fly. The objective of this research was to determine the most effective height level of the trap to capture fruit fly. This experiment was conducted at the Great Giant Foods, Lampung. The experiment was arranged in the randomized block design which consisted of 6 treatments and 5 replications. The treatments were trap height level at 50 cm, 75 cm, 100 cm, 125 cm, 150 cm, and 175 cm above the ground. Each trap was laced with 2 ml of ME block. The results showed that height variations affected the number of captured fruit fly in crystal guava field. The best trap for catching fruit flies on crystal guavas that have been produced for more than a year old that have 150 cm tall plants is one with a height level of 125 cm. The fruit flies caught were identified as Bactrocera dorsalis and B. carambolae.
