稻纵卷叶螟食诱剂在水稻上的应用研究初报

Preliminary Application of Food Attractant of Rice Leaf Folderon Rice

2021年6—10月在上海松江区开展了食诱剂对稻纵卷叶螟在水稻上诱集效果试验,解剖了雌虫的卵巢,并比较了食诱与性诱和灯诱的防治效果。结果表明,食诱剂的诱虫效果优于性诱,可诱集到的Ⅰ级卵巢雌成虫占比达到30.95%,且未交配率达96.15%,被诱捕到的雌虫数量显著多于雄虫,雌雄比为2.34。综合分析表明,食诱具有雌雄同诱、诱集低级别卵巢发育阶段未交配雌虫的优点,为稻纵卷叶螟绿色防治提供了理论依据。

The experiment on the trapping effect of food attractant on rice leaf folder was carried out in Songjiang of Shanghai from June to October in 2021,in comparison with traditional methods such as sex pheromone trapping,light trapping.Food attractant trapping was overall better than sex pheromone trapping.The proportion of female adults in grade I ovary was 30.95%,and the non-mating rate was 96.15%.The number of trapped females was significantly higher than that of males,with a female-to-male ratio of 2.34.Thus,food attractant trappings can trap both male and female and trap unmatched females at low-level ovarian development stage,which provides a theoretical basis for the green control of rice leaf folder.
