【摘要】 采用浸渍法和喷雾法测定了d-柠檬烯对柑橘全爪螨成螨、卵以及若螨、产卵抑制作用的生物活性。结果表明,d-柠檬烯对柑橘全爪螨成螨和若螨的毒杀作用较低;对卵具有一定毒杀活性,48 h的LC₅₀值为231.73 mg/L;对成螨产卵具有较好的抑制作用,72 h的LC₅₀值为54.19 mg/L。研究表明d-柠檬烯对柑橘全爪螨的作用方式主要以抑制产卵为主,盆栽试验结果也表明了这一特性。更多还原

【Abstract】 The biological activities of d-limonene against female adults, nymphs, eggs and oviposition inhibition of Panonychus citri were evaluated in this study with dipping and spraying. It suggested that d-limonene had low toxicity on adults and nymphs, but showed some extent toxic activity against eggs with LC₅₀ values of 231.73 mg/L at 48 h after treated. At the same time, d-limonene proved to inhibit oviposition effectively with LC₅₀ values of 54.19 mg/L and the number of eggs was decreased obviously after treated with d-limonene in pot experiments. The inhibition of oviposition is an important action for d-limonene to control mite.更多还原
