据我们观察,德国小蠊有自洁习性。蟑螂的触角分节,前、中,后足均分节长刺,各附节之间生附节盘。这些特殊构造,使其肢体易粘附细粉状物。蟑螂的自洁是通过口器完成的,利用其自洁习性,将其肢体粘附的胃毒型杀蟑药粉摄入体内,定能提高药杀效果。为此,在实验室进行了颗粒剂和粉剂的药效对照试验。 According to our observation, German cockroaches have self-cleaning habits. Cockroach antennae section, before, during and after the foot are long stab section, epiphyseal appendages between the appendages. These special structures make it easy for them to adhere to the fine powder. Cockroach self-cleaning is done through the mouthparts, the use of its self-cleaning habits, its limbs adhesion of stomach poisoning type cockroach powder intake into the body, will be able to improve the drug kill effect. To this end, the controlled trials of granules and powders were conducted in the laboratory.
