It contains the pengorok fly genus Liriomyza, the order Diptera, family and Agromyzide. The genus Liriomyza consists of many species. Flies with this type of feeding polifag can be found on many different types of plant (Baliadi 2010). General pest on the leaves found on the stage of development of Liriomyza in the form of larvae. The larvae of slitting the sections network host plant palisade. Penggorok leaf flies attack symptoms easily recognized by the presence of white grooved korokan liang nodes on the mesofil leaves. These symptoms are found on the leaves of the plant. Liang korokan color will change to brownish, and attacks the larvae of Liriomyza spp. flourish in it. The symptoms are typical of the flies penggorok leaves (Baliadi 2010). This is in accordance with the observations made in the seedbed teak (Figure 21). There is a Groove or a rut gorokan on the leaves of teak, liang gorokan the Brown. Based on the literature already mentioned, liang gorokan which Brown is the attack of penggorok flies. Pest control penggorok fly (Liriomyza sp.) can use the trap color is berperekat. The use of trap color that can be used for pest control fly penggorok is the color yellow. According to Andrey et al. (1999) in Sunarno (2011), the yellow trap of plastic materials that are smeared with lubricant more effectively controlling the flies pengorok leaves. This is likely caused by a contrasting yellow and shiny so flies are more interested than other types of yellow trap. In addition, the yellow plastic more resistant to rain and the Sun making it more adherent and more durable. The yellow trap installation is adapted to the height of the trap. The most efficient trap installation was installed around the plant. According to Alwi et al. (2000), the installation of the trap around the plants provide efficient results due to fly flying high just around the plant and the size of the body of the fly is relatively small, so that the migration of blow flies are very dependent on the wind.
