Last instar larvae of Locusta migratoria can be protected ("vaccinated") against lethal doses of Bacillus thuringiensis by previous injections of low doses of this pathogen. If iron saccharate is injected in to larvae prior to the administration of the "vaccinating" dose of Bacillus thuringiensis, no antibacterial protection can be induced. Injection of iron saccharate in to "vaccinated" larvae does not interfere with the induced protection; such larvae resist lethal doses.
通过预先注射低剂量的苏云金芽孢杆菌，可使飞蝗末龄幼虫免受致死剂量该病原体的侵害（“接种疫苗”）。如果在给予“接种疫苗”剂量的苏云金芽孢杆菌之前向幼虫注射含糖铁，就无法诱导出抗菌保护作用。向“接种疫苗”的幼虫注射含糖铁不会干扰诱导产生的保护作用；此类幼虫能抵抗致死剂量。
