东方蝗卵蜂Scelio orientalis Dodd是越北腹露蝗Fruhstorferiola tonkinensis Will.卵的寄生性天敌。2004～2006年对广东省北部越北腹露蝗卵粒和卵块寄生率分别为43.18%和89.34%。东方蝗卵蜂产卵在越北腹露蝗卵中,幼虫期为2龄,每粒被寄生的蝗卵只出1头蜂。东方蝗卵蜂的产卵系统发达,不仅骨化程度高,而且具有伸缩性。雌雄性比约为1:0.6,羽化后即可交配。以5%的葡萄糖溶液喂养成蜂,最多可存活31d。东方蝗卵蜂可能是某些年份越北腹露蝗种群下降的重要因子。
Scelio orientalis Dodd is a parasitic natural enemy of Fruhstorferiola tonkinensis Will. From 2004 to 2006, the parasitism rates of eggs and eggs of Abies sequins in northern Guangdong were 43.18% and 89.34%, respectively. Oriental locust egg bee egg spawning in the locust egg, the larvae of 2 years old, each locust egg parasitic was only 1 bee. Oriental locust egg bee oviposition system developed, not only high degree of ossification, but also has flexibility. Male and female ratio of about 1: 0.6, can be mated after emergence. Feeding bees with 5% glucose solution can survive for up to 31 days. Eastern locust eggs may be an important factor in the declining population of Locusta migratoria in some years.
