摘要:
为寻找研制新型绿色杀线虫生物制剂,首次报道利用灵菌红素(prodigiosin,简称PGN)对混合虫龄松材线虫的生物活性,灵菌红素是一种广泛分布于环境中的黏质沙雷氏菌的次生代谢产物,试验测定不同浓度下灵菌红素的杀虫活性及对松材线虫卵孵化率的影响。离体杀虫试验结果表明,灵菌红素对松材线虫各虫龄段都有较高的生物活性,32 h 时的LC90为(90.24±1.41)mg/L,阳性对照组硫酸铜的LC90为(60.60±1.48)mg/L;在离体虫卵孵化率测定试验中,灵菌红素在较低浓度时就已经表现出较高的生物活性,浓度为9.5 mg/L时,卵的孵化率仅为45.5%,与此同时,对照组的孵化率为97.6%。灵菌红素以其杀虫效率高、环境污染小、来源广泛等优势,在农林业生产中有极好的应用前景。
