Abstract
Abstract Shorea sp. (meranti) is a wood-producing tree from Indonesia that has many benefits in world trade. Meranti cultivation is carried out to rehabilitate and develop plantation forests. However, meranti cultivation is susceptible to various pest attacks, including Calliteara cerigoides . This study aimed to determine the food preferences of C. cerigoides and to analyze the phytochemical compounds in meranti leaves. Pest food preferences were tested by testing three meranti leaf species on C. cerigoides larvae. Three species of meranti were Shorea selanica, S. pinanga , and Shorea sp. Phytochemical tests were carried out by identifying seven secondary metabolic compounds in meranti leaves. The results showed that C. cerigoides larvae preferred S. selanica leaves and survived until the seventh instar. The content of tannin and hydroquinone phenolic compounds in the leaves of S. pinanga is thought to be an obstacle in the pest’s food preference, causing the larvae to die in the third instar. The content of alkaloid and flavonoid compounds in the leaves of Shorea sp. was suspected to be the cause of the larvae not surviving until the instar phase and only until the fourth instar. Morphological factors and the content of chemical compounds in meranti leaves affect the eating preferences of larvae.
