| 中文摘要: |
| 为明确贵州省黔西南州安龙县芒果园实蝇科害虫种类及种群消长动态，采用性诱剂、食诱剂等方式开展实蝇害虫的诱集。经过持续跟踪调查，明确了该地主要的实蝇科害虫种类分别为桔小实蝇Bactrocera dorsalis，占比94.85%；其次是南瓜实蝇Bactrocera tau、具条实蝇Bactrocera scutellata，分别占比2.51%、1.45%；黒漆实蝇Zeugodacus scutellaris （Bezzi）（1.01%）、三点棍腹实蝇Dacus trimacula （Wang）（0.02%）、泰实蝇Bactrocera thailandica（Drew &Hancock）（0.16%）和瓜实蝇Bactrocera cucurbitae（0.01%），其中桔小实蝇占据了主要生态位。从种群消长动态分析，7月3日至8月5日，桔小实蝇数量出现急剧上升，10月11日达到高峰值。由于安龙县地理位置及气候的特殊性，桔小实蝇可常年发生，成为一个向外输出虫源的虫源地。为此，在桔小实蝇的防控上，重点是降低虫口基数。可常年设置性诱剂诱杀，结合收获后捡拾落果集中处理、药剂封杀土表等措施防控桔小实蝇的为害。 |

| To identify the species and population fluctuation dynamics, the fruit flies(Diptera:Tephritidae) in mango orchards in Anlong County, Qianxi’nan Prefecture, Guizhou Province were collected using sex and food attractants. After continuous tracking, it was identified that Bactrocera dorsalis (Hendel) was the main species, accounting for 94.85%, followed by Bactrocera tau (Walker), accounting for 2.51%, Bactrocera (Zeugodacus) scutellata (Hendel), accounting for 1.45%, Zeugodacus scutellaris (Bezzi) (1.01%), Dacus trimacula (Wang) (0.02%), Bactrocera thailandica (0.16%), and Bactrocera cucurbitae (0.01%), with B. dorsalis dominated the ecological niche. The number of B. dorsalis increased sharply from July 3 to August 5 and peaked on October 11, 2019, according to the analysis of population fluctuation dynamics. The adults of B. dorsalis could be found all year round in Anlong County due to the specific geographical location and climate, which became a source of exogenous pests. Thus, to prevent and control the pest, it was so critical that the population base of B. dorsalis needs to be suppressed. The damage of. B. dorsalis can be prevented and controlled using sex attractants all year round, collecting and processing dropped fruits after harvest intensively, killing larvae and pupae under soil surface with insecticides. |
