肚倍是一种重要的五倍子。肚倍蚜各世代都行卵胎生,两性生殖出现在春季。迁移蚜体内各卵和胚胎发育整齐,生殖期短;除雌蚜只生殖1头无生殖历期外,其余各无翅虫型体内各卵和胚胎渐次发育、渐次成熟、渐次产出,生殖期长。瘿内世代生殖量大;瘿外世代生殖量小,无翅侨蚜更小。除干雌未观察外,其他各虫型的个体初产出时均有一层软膜包被,脱膜后才能正常活动。迁移蚜生殖特性的利用于肚倍生产的关系极为重要。
Abdominal times is an important gallnut. Belt aphids all generations of ovulation, amphiprotic appear in the spring. The migration of aphids eggs and embryos in vivo development and tidy, short reproductive period; except for female aphids reproductive only 1 non-reproductive period, the rest of the non-flies worms in vivo each egg and embryo gradually developed, gradually mature, gradually output, reproductive period long.瘿 large within the generation of reproductive capacity; 瘿 small reproductive generation of offspring, wingless anopheles smaller. In addition to the dry female did not observe, the other individual types of pests have a layer of soft tissue coated at the beginning of production, after the release of the normal activities. The relationship between reproductive traits that migrate aphids and belly production is of paramount importance.
