摘要: 为明确西花蓟马在不同种植环境菊苗上的种群活动规律与季节消长动态,采用五点取样,利用粘虫板诱集法对不同种植环境菊苗上西花蓟马种群动态进行调查,分析了2018—2020年在不同种植环境下前茬苗上西花蓟马对后茬苗的影响。结果表明:西花蓟马种群数量在前茬苗和后茬苗上均出现先增加后减少的趋势,西花蓟马主要发生期的时长与菊苗种植时间的长短有关;在不同种植环境下,前茬苗上西花蓟马的主要发生期均集中在3月末—6月末,种群数量最多时露地可达654.6头·板-1,单体棚可达373.8头·-1,连栋大棚可达146.4头·板-1;后茬苗上主要发生期集中在7月中旬—10月中旬,种群数量最多时单体棚为551.2头·板-1,露地为134.3头·板-1,连栋大棚为57.7头·板-1;前茬苗上西花蓟马主要发生期的种群数量露地>单体棚>连栋大棚,后茬苗上西花蓟马主要发生期的种群数量单体棚>露地>连栋大棚;前茬苗上西花蓟马对后茬苗上西花蓟马的影响露地>单体棚>连栋大棚。连栋大棚内西花蓟马种群数量最小且在连栋大棚内前茬苗对后茬苗西花蓟马种群数量影响最小,可以有效控制菊苗上的西花蓟马种群数量。

Abstract: We used five-point sampling and sticky board method to investigate population dynamics of F. occidentalis on chrysanthemum seedlings under different planting environments. The effects of F. occidentalis size of fore-rotating seedlings on F. occidentalis size of current-rotating seedlings were analyzed from 2018 to 2020. The results showed that population size of F. occidentalis increased first and then decreased in both the fore-rotating and current-rotating seedlings. The duration of the main activity period of F. occidentalis was related to the planting time of chrysanthemum seedlings. The main activity period of F. occidentalis on fore-rotating seedlings were from late March to late June under different planting environments, with peak population size of 654.6 ind·board-1 in open field, 373.8 ind·board-1 in single greenhouse and 146.4 ind·board-1 in conjoined greenhouse. The main activity period of F. occidentalis on current-rotating seedlings was from mid-July to mid-October, while population peaked to 551.2 ind·board-1 in single greenhouse, 134.3 ind·board-1 in open field and 57.7 ind·board-1 in conjoined greenhouse. F. occidentalis population size on fore-rotating seedlings during the main activity period was in an order of open field > single greenhouse > conjoined greenhouse, while that on current-rotating seedlings was in an order of single greenhouse > open field > conjoined greenhouse. The effect of F. occidentalis population size of fore-rotating seedlings on F. occidentalis population size of current-rotating seedlings was increased in an order of open field > single greenhouse > conjoined greenhouse. The population size of F. occidentalis of fore-rotating seedlings in conjoined greenhouse had the lowest influence on that of current-rotating seedlings, which could effectively control the population size of F. occidentalis on the chrysanthemum seedlings.
