摘要
铃木氏果蝇是危害樱桃等多种水果果实的重要害虫,近年来在国内许多樱桃园暴发成灾。为明确樱桃园铃木氏果蝇的发生危害情况,掌握其发生规律,进而探究有效预防并控制其发生危害的措施,于2015年8月至12月,在系统监测樱桃园铃木氏果蝇种群动态的基础上,通过田间试验调查研究不同诱捕器、不同诱剂及诱捕器上端放置不同颜色塑料球对铃木氏果蝇及樱桃园常见4种果蝇混合种群的诱捕效果。结果表明:陕西杨凌樱桃园中,铃木氏果蝇的数量约占樱桃园果蝇混合种群发生量的1/3,并在10月中旬达到最大值;自制矿泉水瓶诱捕器的诱捕效果显著优于综合型诱捕器的诱捕效果;糖醋液的诱捕效果明显,而香蕉香精作为诱剂对铃木氏果蝇及其樱桃园果蝇混合种群几乎无诱捕作用;在自制矿泉水瓶诱捕器上端加置橙色塑料球,对铃木氏果蝇及其混合种群的诱捕有增效作用。
Drosophila suzukii Matsumura,is an important pest which causes severe damage in cherry and other fruits. Many cherry orchards suffered great losses because of plague of D. suzukii in recent years. A research of trapping effect of D. suzukii and the other four species of common fruit flies were conducted during August to December in 2015 with different trappers, baits and plastic color balls based on dynamics monitoring of fruit flies population in Yangling, Shaanxi province. The results showed that the number of D. suzukii occupied on third of mixed Drosophila population with the peak in mid-October in cherry orchard. The trapping effect of home-made water bottles was significantly better than that of comprehensive type. The sweet and sour liquid was pretty efficient, while the Ba- nana Flavor was almost useless. With reference to the seven colors in the survey, the entrapment with orange plastic balls showed the best synergistic effect in trapping D. suzukii and other fruit flies.
