以葡萄园果蝇为研究对象,采用调查及不同诱捕器诱集的方法,研究了葡萄园果蝇全年种群动态及不同诱捕器对果蝇的引诱效果,并寻找了诱捕器的最佳悬挂高度。结果表明:葡萄园果蝇种群动消长动态中共出现12个峰,其中果蝇发生高峰出现在5月下旬至6月上旬、9月中旬至10月上旬;糖醋液、香蕉果肉、糖醋液+香蕉果肉、葡萄果肉及糖醋液+葡萄果肉均对果蝇有显著引诱效果,其中以糖醋液+香蕉果肉与香蕉果肉诱集效果最好,且糖醋液与香蕉果肉、葡萄果肉混合并未产生明显的增效或抑制作用。葡萄园诱捕器最佳悬挂高度以0.8~1.2m为宜。
Taking the fruit fly of vineyard as the research object, this paper studied the population dynamics of the fruit fly in the vineyard and the luring effect of different traps on the fruit fly, using the method of investigation and trapping of different traps, and looked for the best suspension of the traps height. The results showed that there were 12 peaks in the dynamic and long dynamic state of fruit fly population in the vineyard, including the peak occurrence of fruit flies in late May to early June and mid-September to early October. The sweet and sour liquid, banana pulp, + Banana pulp, grape pulp and sweet and sour vinegar + grape pulp all have significant attraction to fruit flies, of which sweet and sour liquid + banana pulp and banana pulp are best, and sweet and sour liquid are mixed with banana pulp and grape pulp Did not produce significant synergistic or inhibitory effect. Vineyard traps the best suspension height of 0.8 ~ 1.2m is appropriate.
