When released near a bagworm infestation, trichogramma wasps will lay their eggs inside the eggs of bagworms, with the wasp larvae then feeding on baby bagworms and preventing the infestation ...
寄生蜂物种间的基因组大小变化较大,目前已知最小的为40 Mb左右而最大的则超过了2 Gb(图2)。近期的比较基因组研究表明,寄生蜂基因组大小的变化与其中的转座子含量显著相关。进一步的分析表明,不同类型的转座子在不同寄生蜂的基因组大小演化中扮演重要角色 ...
