Insects have close symbiotic relationships with several microbes, which extends the limited metabolic networks of most insects. Using symbiotic microorganisms for the biological control of pests and insect-borne diseases has become a promising direction. (L.) (Blattaria: Blattidae) is a public health pest worldwide, which is difficult to control because of its strong reproductive ability, adaptability, and resistance to insecticides. In this paper, the diverse biological functions (nutrition, reproductive regulation, insecticide resistance, defense, and behavior) of symbionts were reviewed, and new biological control strategies on the basis of insect-symbiont interaction were proposed. We highlight new directions in control, such as suppressing cockroach population using or paratransgenes, and combining fungal insecticides with synergistic agents to enhance insecticidal efficacy.
昆虫与多种微生物有着密切的共生关系，这扩展了大多数昆虫有限的代谢网络。利用共生微生物进行害虫和虫媒疾病的生物防治已成为一个有前景的方向。蜚蠊（L.）（蜚蠊目：蜚蠊科）是一种全球范围内的公共卫生害虫，由于其强大的繁殖能力、适应性和对杀虫剂的抗性，难以控制。本文综述了共生体的多种生物学功能（营养、生殖调控、抗杀虫剂、防御和行为），并基于昆虫 - 共生体相互作用提出了新的生物防治策略。我们强调了防治方面的新方向，例如使用共生菌或paratransgenes抑制蟑螂种群，以及将真菌杀虫剂与增效剂结合以提高杀虫效果。
