利用斑头陡盾茧蜂防治粗鞘双条杉天牛的新技术

斑头陡盾茧蜂是1973年在粗鞘双条杉天牛上发现的体外寄生蜂， 寄生粗鞘杉天牛为首次记录。斑头陡盾茧蜂隶属于膜翅目， 茧蜂科， 矛茧蜂亚科， 矛茧蜂族。在华南南部地区， 于12月下旬或1月上旬在杉木皮层及边材之间的天牛虫道内结茧化蛹越冬， 翌年2月中旬左右羽化为成蜂。1年发生15- 16代， 一般完成一代要20-25天。繁蜂的最适温度为23-28℃， 最适相对湿度为70%左右。长角凿点天中、松墨天牛、杉棕天牛、竹虎天牛及粗鞘双条杉天牛等中小型天牛幼虫是繁殖该蜂的优良寄主。繁蜂的主要工具有繁蜂箱、繁蜂架、繁蜂板和杉皮等。天牛幼虫在林木皮层为害时为最佳放蜂时期， 适时早放可提高放蜂效果。蜂在老熟蛹期释放为好。放蜂量与林间天牛虫口数成1Spotted-head Steep-shield Braconid Wasp (*Spathius cephalofasciatus*) was discovered as an ectoparasitoid on the thick-sheath double-striped fir longhorn beetle (*Semanotus bifasciatus*) in 1973, and its parasitism on this longhorn beetle was recorded for the first time. This wasp belongs to the order Hymenoptera, family Braconidae, subfamily Doryctinae, tribe Doryctini. In southern South China, it overwinters as cocoons and pupae within the longhorn beetle tunnels between the bark and sapwood of Chinese fir, with cocoon formation occurring in late December or early January, and adult eclosion taking place around mid-February of the following year. It has 15 to 16 generations per year, with each generation typically requiring 20 to 25 days to complete. The optimal temperature for mass rearing this wasp is 23–28°C, and the optimal relative humidity is approximately 70%. The larvae of medium and small-sized longhorn beetles, including the long-horned drilling longhorn beetle, pine sawyer beetle (*Monochamus alternatus*), fir brown longhorn beetle (*Callidium villosulum*), bamboo tiger longhorn beetle (*Chlorophorus annularis*), and thick-sheath double-striped fir longhorn beetle (*Semanotus bifasciatus*), are excellent hosts for mass rearing this parasitoid wasp. The main tools for mass rearing include wasp rearing boxes, rearing racks, rearing plates, and Chinese fir bark, among others. The optimal period for wasp release is when longhorn beetle larvae are feeding within the tree bark; releasing wasps early at the appropriate time can improve release efficiency. It is recommended to release the wasps during their mature pupal stage. The ratio of released wasps to the forest longhorn beetle population is 1
