杉肤小蠹的捕食天敌——红腹郭公虫的生物学特性
Biological Characteristics of Clerus rufiventris——A Predator of Phloeosinus sinensis in the Forest of Cunninghamia lanceolata
摘要
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.关键词
