Sugarcane thrips, Fulmekiola serrata (Kobus), is a common leaf pest of sugarcane. To clarify the occurrence and overwintering of F. serrata in Yunnan sugarcane planting areas of China in winter and the influencing factors, five surveys on the occurrence and overwintering of thrips in sugarcane were carried out at three bases of the Sugarcane Research Institute, Yunnan Academy of Agricultural Sciences, in January and February 2023, targeting five varieties and two sugarcane growth periods. The results showed that the average number of adults was 2.86 individuals/plant, significantly greater than that of nymphs, at 0.07 individuals/plant. The average number of females was 1.87 individuals/plant, significantly greater than that of males, at 0.06 individuals/plant. Except for the first survey, the average number of thrips of Yunzhe 081,608 was the highest in the other four surveys, but Guiliu 05,136 was the lowest in the five surveys. The average number of thrips at the seedling stage was 2.86 individuals/plant, significantly greater than that at the mature stage, at 0.98 individuals/plant. The average numbers of adults were 2.48 and 2.12 individuals/plant at the Mabao and Sugarcane Institute bases, respectively, significantly greater than that at the Lengshuigou base, at 1.16 individuals/plant. In conclusion, F. serrata mainly overwintered as adults in the heart leaves of sugarcane at the seedling stage, with females in the majority, and the sugarcane growth period had the greatest influence on the average number of thrips. As the planting area of autumn-planted sugarcane and winter-planted sugarcane increases annually, clarifying the occurrence and overwintering of thrips in winter can provide a foundation for monitoring and effectively managing of F. serrata.
甘蔗蓟马（Fulmekiola serrata (Kobus)）是甘蔗常见的叶部害虫。为明确中国云南甘蔗种植区冬季甘蔗蓟马的发生及越冬情况及其影响因素，2023年1月和2月，在云南省农业科学院甘蔗研究所的三个基地针对五个品种和两个甘蔗生育期开展了五次甘蔗蓟马发生及越冬情况调查。结果表明，成虫平均虫口密度为2.86头/株，显著高于若虫的0.07头/株。雌虫平均虫口密度为1.87头/株，显著高于雄虫的0.06头/株。除第一次调查外，云蔗081608在其他四次调查中的蓟马平均虫口密度最高，但桂柳05136在五次调查中最低。苗期蓟马平均虫口密度为2.86头/株，显著高于成熟期的0.98头/株。在马关基地和甘蔗研究所基地，成虫平均虫口密度分别为2.48头/株和2.12头/株，显著高于冷水沟基地的1.16头/株。综上所述，甘蔗蓟马主要以成虫在苗期甘蔗的心叶中越冬，雌虫居多，甘蔗生育期对蓟马平均虫口密度影响最大。随着秋植蔗和冬植蔗种植面积逐年增加，明确冬季蓟马的发生及越冬情况可为甘蔗蓟马的监测和有效防控提供依据。
