摘要

The gall-inducing weevil Acythopeus glyptorhis Prena (2021) is reported for the first time in India, where it was found infesting teasel gourd (Momordica subangulata subspp. renigera) plants in northeast India. Both male and female weevils were observed congregating near the nodes of M. subangulata vines, where they mate and oviposit on the stems. After hatching, the larvae feed on internal stem tissues, leading to the formation of galls. Pupation occurs within the larval tunnels. A total of 53.33% plant damage was recorded between June and October, with node damage ranging from 12.67 to 17.67%. This study not only represents the first record of A. glyptorhis in India but also its first association with teasel gourd (M. subangulata) including its natural history on new host. Additionally, it confirms the pest status of A. glyptorhis, which inflicts economic losses to high-value teasel gourds in India, and presents key diagnostic characteristics, including detailed morphometric data for both sexes, with emphasis on the first description of the female genitalia. Given the significant damage to M. subangulata, further research on the pest’s bio-ecology, damage patterns, and economic impact is crucial for developing effective management strategies.
