摘要
舟蛾赤眼蜂（ＴｒｉｃｈｏｇｒａｍｍａｃｌｏｓｔｅｒａｅＰａｎｇｅｔＣｈｅｎ）在淮北地区自然界能安全越冬。该蜂每年１０月上旬至１１月上旬寄生柳毒蛾（Ｓｔｉｌｐｎｏｔｉａｓａｌｉｃｉｓ（Ｌｉｎｎａｅｕｓ））卵，卵粒寄生率为３８．１７％，以预蛹越冬，翌年３月下旬至４月上旬羽化，羽化率达９７．２３％。越冬代历期１７８～１８２天。其越冬前的寄主是杨扇舟蛾（Ｃｌｏｓｔｅｒａａｎａｃｈｏｒｅｔａ（Ｆａｂｒｉｃｉｕｓ））卵、栎枯叶蛾（Ｇａｓｔｒｏｐａｃｈａｑｕｅｒｃｉｆｏｌｉａ（Ｌｉｎｎａｅｕｓ））卵和盗毒蛾（ＥｕｐｒｏｃｔｉｓｓｉｍｉｌｉｓＦｕｅｅｓｓｌｙ）卵，越冬后的最初寄主是栎枯叶蛾卵、柳天蛾（即蓝目天蛾）（ＳｍｅｒｉｎｔｈｕｓｐｌａｎｕｓＷａｌｋｅｒ）卵、杨二尾舟蛾（ＣｅｒｕｒａｅｒｍｉｎｅａｍｅｎｃｉａｎａＭｏｏｒｅ）卵、小杨天社蛾（ＭｉｃｒｏｍｅｌａｌｏｐｈａｔｒｏｇｚｏｄｙｔａＧｒａｅｓｅｒ）卵和双尾天社蛾（ＣｅｒｕｒａｅｒｍｉｎｌａｍｅｏｃｉａｎａＭｏｏｒｅ）卵。在其越冬前后转主期，野外适时人工补充寄主卵，可相应增加其越冬基数和春季自然种群数量。
Trichogramma closterae overwinters safely in nature in Huaibei Region. It parasitizes the eggs of Stilpnotia salicis from first ten days of October to first ten days of November every year, and overwinters in prepupae. The parasitism rate is 38.17% in nature. The adults emerge from last March to early April every year. The emergence rate reaches 97.23%. It spends 178 182 days in winter. Before overwintering its hosts are the eggs of Clostera anachoreta, Gastropacha quercifodia and Euproctis similis. After overwintering its first hosts are mainly the eggs of Gastropacha quercifolia, Smerinthus planus, Cerura erminea menciana, Micromelalopha trogzodyta and Cerura erminla meociana. During the hosts change Period before and of ter averwintering artificial supplement of hosts in field can correspondingly incre the parasitoid's ase cardinal overwintering density and natural density in Spring.
