Termites are known as social insects worldwide. Presently in China 473 species, 44 genera and 4 families of termites have been reported. Of them, 111 Reticulitermes species are widely spread in different zones of China. The dispersion flight season of these Chinese Reticulitermes species are usually started from February to June, but in some regions different species are distributed, sharing their boundaries and having overlapping flight seasons. These reasons become important sources of hybridization between two different heterospecific populations of termites. It was confirmed that the fertilized eggs and unfertilized eggs of some Reticulitermes termites have the capacity of cleavage. While the unfertilized eggs of R. aculabialis, R. chinensis and R. labralis cleaved normally and the only R. aculabialis unfertilized eggs develop in embryos. While, the R. flaviceps and R. chinensis were observed with their abnormal embryonic development, and not hatching of eggs parthenogenetically. They were reported more threatening to Chinese resources as they propagate with parthenogenesis, hybridization and sexual reproduction. Eggshell and macrophiles of eggs play important roles in species identification and control. Although, they are severe pests and cause a wide range of damages to wooden structures and products in homes, buildings, building materials, trees, crops, and forests in China's Mainland.
白蚁是世界范围内的社会性昆虫。目前在中国已报道了 473 种、44 属和 4 科白蚁。其中,111 种家白蚁分布广泛,分布于中国不同地区。这些中国家白蚁的扩散飞行季节通常从 2 月到 6 月开始,但在一些地区,不同的物种分布,共享边界,飞行季节重叠。这些原因成为两种不同白蚁种群之间杂交的重要来源。已经证实,一些家白蚁的受精卵和未受精卵具有分裂能力。而 R. aculabialis、R. chinensis 和 R. labralis 的未受精卵正常分裂,只有 R. aculabialis 的未受精卵发育成胚胎。然而,观察到 R. flaviceps 和 R. chinensis 的胚胎发育异常,未受精卵孤雌生殖孵化。由于它们以孤雌生殖、杂交和有性生殖的方式繁殖,因此被认为对中国的资源构成更大的威胁。卵壳和卵的亲代物质在物种鉴定和防治中起着重要作用。尽管它们是严重的害虫,对中国大陆的木质结构和产品、房屋、建筑物、建筑材料、树木、作物和森林造成广泛破坏。
