【摘要】 中华广肩步甲是一种重要害虫天敌。根据在河南省安阳地区的调查,一年发生1—2代,以成虫过冬。成虫捕食盛期在6月中旬,7月上旬大部分个体进入滞育,次年4月上中旬出蛰,6月中旬产卵,每雌可产卵2000余粒。成虫和幼虫对粘虫的控制作用显著。此虫喜在食料丰富,作物密植,土壤湿润疏松的条件下生活,凡作物套种,精耕细作的农田,虫口数量较大,对害虫的控制作用明显。经初步试验,利用人工饲料,可以饲养繁殖,产生正常后代,为今后大量繁殖利用提供了初步经验。更多还原

【Abstract】 Calosoma chinenese Kirby is an important natural enemy to pest—insects.Ac-cording to the investigations in the Anyang Prefecture of Henan Province,itoceurres one or two generations a year and lives through the winter in the formof its imago.The surperb period of its feeding is in the middle of June,andthe much more of the imagoes diapause in the first ten-day period of July,appear in the first ten-day period and the middle of April next year and layeggs in the middle of June.A female may lay about 2000 eggs.The control of the imagoes and larvae to Mythimna separata is significant.Calosoma ehinenese prefers to live where diets are rich,crops intensive and soils-damp and loose.The population is large wherever there are interplanted cropsand intensive cultivation fields,and its control to destructive insects is obvious.By testing,C.chinenese can be breeded and reproduced with an artificial diet,producing its normal generation.更多还原
