ABSTRACT

    Aonla (Phyllanthus emblica L.) is a crop with emerging medicinal uses, but information regarding its pests has not been reported in Taiwan. In this study, the results show that the main of aonla pests include Polyphagozerra coffeae (Nietner), Euproctis taiwana (Shiraki), Caloptilia sp., Selepa celtis Moore, and Eumeta spp during 2018 to 2019. P. coffeae was recorded in Feb-Apr and May-Oct and its larvae damaged aonla branches in Gongguan, Touwu, Zaoqiao, Sanwan, Zhuolan, Houlong and Zhushan. E. taiwana was recorded in Mar-Apr, and its larvae resulted in aonla leave damage founded in Gongguan, Zaoqiao, Dahu and Zhuolan. Caloptilia sp. was recorded in Jun to Nov, and its larvae damaged aonla leaves in Gongguan, Zaoqiao,and Houlong. S. celtis threat times were recorded in Mar, May, Jun and Sep, and its larvae eat aonla leaves and fruits founded in Gongguan and Zaoqiao. Eumeta spp. were recorded in May, Jun and Nov, and its larvae eat aonla leaves founded in Gongguan, Zaoqiao and Dahu. There is no damage caused by pests in January and December; this may be because aonla leaves fall in winter. Compared with this study, we identified some lepidopteran pest species to be different in China and India according to their literature. There is have to notice other countries’ pest before introducing aonla cultivar to Taiwan.
