摘要
为明确河南漯河夏玉米中后期鳞翅目害虫的种群优势度和生态位特征,分别于2022、2023年当地夏玉米吐丝期、灌浆期、乳熟期和蜡熟期开展田间调查。结果显示:漯河夏玉米中后期鳞翅目害虫主要有6种:亚洲玉米螟、劳氏黏虫、桃蛀螟、棉铃虫、东方黏虫、草地贪夜蛾;两年间亚洲玉米螟和劳氏黏虫均为优势种;桃蛀螟在2022年为丰盛种,在2023年为优势种;棉铃虫均为丰盛种;东方黏虫和草地贪夜蛾均为少见种;两年间亚洲玉米螟空间生态位宽度和时间生态位宽度均为最大;上述6种害虫的空间生态位重叠指数较高,时间生态位重叠指数分散。该结果可为黄淮海地区夏玉米穗期鳞翅目害虫监测预警与综合防治提供理论依据。
The objective of this study was to clarify the dominant species and niche characteristics of Lepidoptera pests in the middle-late stage of summer maize in Luohe,Henan Province.To this end,an investigation was conducted to ascertain the species and number of pests on summer maize at the stages of silking,grain-filling,milk,and wax maturity in Luohe during the years 2022 and 2023.The findings revealed the identification of six primary Lepidoptera pest species in the middle and late growth stage of summer maize,namely Ostrinia furnacalis,Leucania loryi,Dichocrocis punctiferalis,Helicoverpa armigera,Mythimna separata,and Spodoptera frugiperda.In both years,O.furnacalis and L.loreyi were the dominant species,while H.armigera was abundant.In contrast,M.separata and S.frugiperda were rare species.D.punctiferalis exhibited high abundance in 2022 and dominated in 2023,while O.furnacalis demonstrated the most expansive spatial and the longest temporal niche during both years.The six Lepidoptera pests had similar niche overlaps in their spatial niches,however,they demonstrated dispersed niche overlap in their temporal niches.This study provides a theoretical basis for monitoring,early warning,and integrated management of Lepidoptera pests in summer maize at heading stages in Huang-huai-hai regions.
