摘　　要：为查清油茶蓝翅天牛在江西省的发生危害情况和生活史,调查了江西8个县(市、区)的油茶蓝翅天牛发生危害情况。结果表明被害株率、产卵刻槽以崇义县最多,分别为78.85%、5.23个/株,与其他7个县(市、区)均存在显著差异;上犹、于都的被害株率也较高,分别为71.69%、69.64%,显著高于除崇义县的其他5个县(市、区);德兴、余江的产卵刻槽数分别为4.21个/株、3.19个/株,与其他6个县的产卵刻槽数间存在显著差异;余江、于都、上犹、高安的排粪孔数分别为1.72个/株、1.56个/株、1.12个/株、0.81个/株,与其他4个县的排粪孔数间存在显著差异。蓝翅天牛幼虫存活率以于都县油茶林中最高,为62.2%;铅山县最低,仅为2%。经观察,油茶蓝翅天牛在江西2年发生1代,最早羽化日期为4月23日,羽化期可持续到6月中旬。出孔后的成虫3~4 d后交尾产卵,产卵刻槽呈“■”形,每个刻槽内一般产卵1枚,每枝条产卵痕最多可达9个,卵期为10~15 d;以当年及上一年孵化的幼虫在油茶枝条蛀道内越冬。笔者还绘制了油茶蓝翅天牛年生活史表。研究结果可为防治该害虫提供科学依据。To investigate the occurrence characteristics and life history of Chreonoma atritarsis(Pic.)in Jiangxi Province,the occurrence and damage of Chreonoma atritarsis(Pic.)in eight counties(cities and districts)were surveyed.The results showed that the rate of damaged plants and oviposition grooves was highest in Chongyi County,which was 78.85%and 5.23 per plant,respectively,which were significantly different from the other seven counties(cities and districts).The damage rates in Shangyou and Yudu were 71.69%and 69.64%,respectively,significantly higher than those in the other five counties(cities,districts)except Chongyi County.The number of oviposition grooves in Dexing and Yujiang was 4.21 per plant and 3.19 per plant,respectively,with significant differences compared to the other six counties.The number of defecation holes in Yujiang,Yudu,Shangyou,and Gao’an was 1.72 per plant,1.56 per plant,1.12 per plant,and 0.81 per plant,respectively,which were significantly different from those in the other four counties.The survival rate of Chreonoma atritarsis(Pic.)larvae was highest in the Camellia oleifera forest in Yudu County,which was 62.2%,and lowest in Qianshan County,which was only 2%.According to the observation,Chreonoma atritarsis(Pic.)had one generation every 2 years in Jiangxi.The earliest eclosion date was April 23 and the eclosion period could last until mid-June.After 3 to 4 days of hatching,the adults mated and laid eggs.The oviposition groove was in a“”shape,with one egg generally laid in each groove,and the maximum number of oviposition marks per branch was up to 9,with an egg stage of 10~15 days.The larvae hatched in the current year and the previous year overwintered in the branches of Camellia oleifera branches.The author also drew an annual life history table of the Chreonoma atritarsis(Pic.).The research results can provide a scientific basis for the prevention and control of this pest.
