摘要: 杉木是我国南方的重要速生造林树种,但近年来福建、江西、浙江等地遭受了严重干旱和杉肤小蠹Phloeosinus sinensis复合危害,出现了大面积枯死现象。经调查,在受害杉木林分的杉肤小蠹蛀道中发现一种甲虫,对杉肤小蠹具有较强捕食能力,具有一定的控害前景。遂采用野外观察并结合室内饲养明确其生物学特性,以期为开发利用提供科学依据。经鉴定该甲虫为红腹郭公虫Clerus rufiventris,对杉肤小蠹具有较强的捕食能力,1头成虫每日捕食杉肤小蠹成虫达7~10头。卵为乳白色,在25(±1)℃下卵期约为7 d;初孵幼虫乳白色,后呈粉红色,幼虫分3龄,历期约40 d;蛹为离蛹,蛹期约为16~18 d;雌性成虫第5腹板有缺刻,雄性成虫则无;红腹郭公虫雌虫羽化后7~21 d内产卵量少,红腹郭公虫平均产卵量为5粒/雌,羽化后28~42 d产卵量高,平均产卵量为20粒,一生产卵量约为108~114粒。

Abstract: Cunninghamia lanceolata is an important fast-growing afforestation species in southern China. However, in recent years, severe drought and compound infestations by Phloeosinus sinensis in Fujian, Jiangxi, Zhejiang, and other regions have led to large-scale die-offs. Investigations revealed the presence of a beetle within the boreholes of P. sinensis in affected C. lanceolata stands, which exhibited strong predatory capabilities against P. sinensis, indicating potential for pest control. Field observations and laboratory rearing were conducted to clarify its biological characteristics, providing a scientific basis for its utilization. The beetle was identified as Clerus rufiventris, demonstrating a high predation capacity, with a single adult consuming 7-10 adult P. sinensis per day. The egg is milky white, with an incubation period of approximately 7 days at 25(±1) ℃. Newly hatched larva is milky white and later turns pink; the larval stage consists of three instars and lasts about 40 days. The pupa is an exarate pupa, with a pupal period of about 16-18 days. The fifth abdominal ventrite of female adults is notched, while that of males is not. Female C. rufiventris lays few eggs within 7-21 days after emergence, with an average of 5 eggs per female. Egg-laying peaks between 28 and 42 days after emergence, averaging 20 eggs, and the total lifetime fecundity is approximately 108-114 eggs per female.
