A New Pest Insect of Dendrobium: Hypolycaena kina Hewitson

Hypolycaena kina Hewitson was found as a new pest insect infesting Dendrobium in Dehong, Yunnan province, China. The morphological and biological characteristics of H. kina Hewitson at different development stages were observed and the pest infestations were also described in the lab and the field. The results showed that late March was the peak period for occurrence of H. kina Hewitson. The larvae of H. kina fed on flowers of Dendrobium wardianum Warner, and their feeding behavior caused damage to the growth and ornamental value of D. wardianum. Some feasible measures were proposed to control this pest.
