Abstract Fulgoraecia bowringii Newman, 1851 is a true parasite of Pyrops candelaria (Linnaeus, 1758), and is now first record- ed from North Vietnam. Brief biological information is also reported.

Introduction We collected Pyrops candelaria from the trunk of lychee tree planted around village (Fig. 1). If a was The larva of a the parasitic Fulgoraecia bowringii infested by the larva of Fulgoraecia bowringii, we placed it in Newman, 1851 is attached to the dorsal surface of a plant- a plastic bag with its host. Observations were conducted in the hopper (Bowring & Westwood, 1876; Pierce, 1995). It was lab. After death of the host, all the larvae died within several originally thought that the larva ate the waxy secretion of the days. The determination of the moth was based on the figures host (Newman, 1851; Bowring & Westwood, 1876). The host of Bowring & Westwood (1876) and the association of the planthopper, Pyrops candelaria (Linnaeus, 1758), a common host planthopper. and well known pest of lychee, Litchi chinensis, is distributed The specimens reported here are preserved in the Vietnam widely in the Oriental Region; however, the distribution of the National Museum of Nature, Ehime University Museum, and parasitic moth was known only from China (Hong Kong) and Hokkaido University Museum. India (Kato, 1940). In the present paper, we report Fulgoraecia bowringii Results and discussion from Vietnam for the first time. Total of 23 individuals (14 males & 9 females) of Pyrops Materials and methods candelaria (Fig. 2) were collected from six trees, and of these 7 individuals (sex of host: 5 males & 2 females) Collecting data are as follows: [VN50] Cuc Phuong, Ninh were parasitised by Fulgoraecia bowringii (Table 1). The Bình Prov. (165 m), 20.140595N, 105.420878E, 6. III. 2015, H. parasitic larvae were attached to the dorsal surface of the Yoshitomi and R. Okano leg.
