摘要
为明确哈尔滨地区大豆田双斑长跗萤叶甲的种群动态,2021年和2022年在哈尔滨地区利用马氏网和田间扫网法调查监测哈尔滨地区大豆田双斑长跗萤叶甲成虫种群发生情况。结果表明,双斑长跗萤叶甲成虫在大豆田的始见期是在7月7日至7月14日之间,高峰期是在8月4日至8月11日之间,2021年双斑长跗萤叶甲始发期和高峰期比2022年提前7 d,结合2年监测发现盛发期为7月21日至8月25日,长达35 d。综合以上结果,哈尔滨地区大豆田双斑长跗萤叶甲田间始发期为7月初开始在大豆田出现,盛发期为7月下旬到8月中旬,8月初到中旬达到高峰期。因此,哈尔滨地区大豆田双斑长跗萤叶甲最佳防治时期为7月下旬(始盛期)。建议防治双斑长跗萤叶甲采取农业防治、物理防治和化学防治相结合的综合防治措施。
In order to clarify the population dynamics of M.hieroglyphica in Harbin Area,the population of M.hieroglyphica adults was monitored by Malaise traps and sweep net in soybean field in 2021 and 2022.The results suggested that the initial of M.hieroglyphica adults in soybean fields is between July 7 and July 14.The peak period is between August 4 and August 11.Although the initial and peak periods of M.hieroglyphica in 2021 were one week earlier than that in 2022,the full incidence period is the same periods,from July 21 to August 18.In summary,the initial of M.hieroglyphica adults in soybean fields in Harbin Area is in early July;The full incidence period is from late July to mid-August;The peak period is from early August to mid-August.So the best control period of M.hieroglyphica in soybean fields in Harbin is late July(the beginning peak period).The suggestion to control M.hieroglyphica are combine agricultural control,physical control and chemical control.
