摘　　要：研究了黑广肩步甲Calosoma maximociczi Morawitz各虫态的主要生物学特性及其卵的发育起点温度与有效积温。在山东地区,该虫1年发生1代,以成虫在土壤中越冬。成虫在5月中旬至10月上旬发生,6月初开始产卵,卵的发育起点温度为14．66℃,有效积温41．7日度,在25℃下卵期平均为3．69±0．25d;幼虫共3龄,历期分别为3d～5d、4d-5d;平均气温28℃下,预蛹期约为8d-14d,蛹期为10d-15d。成、幼虫以多种鳞翅目幼虫为食。Biology of Calosoma maximociczi Morawitz was observed. It had one generation per year in Shandong province, and overwintered as adult in soil. The adults emerged from mid - May to the first ten days of October, and oviposited in early June. The developmental threshold temperature of egg was 14.66℃, and its effective accumulated temperature was 41.7 degree - day. At 25℃, eggs hatched after 3. 69±0. 25 days, the nymph had three instars, the 1st instar stage was 3-5 days, 2nd instar 3-5days, and 3rd instar 4-5 days. The prepupal stage lasted 8-14 days and the pupal stage lasted 10-15 days at 28℃. Adults and larva preyed on many kinds of Lepidoptera larvae.
