山西三点棍腹实蝇和具条实蝇种群动态监测

2006年,于山西的侯马、长治、交城、祁县、太原,在Steiner诱捕器内加T,Cue,Me诱剂诱集各种实蝇,监测山西境内实蝇的发生动态。结果表明,三点棍腹实蝇(Dacus(Callantra)trimacula(wang))和具条实蝇(Bactrocera(Zeugodacus)scutelltat(Hendel))是山西的优势实蝇种群,各诱集点两种实蝇种群动态基本一致,每年的6月底7月初由南到北相继发生,高峰期出现在8月中下旬至9月上中旬,种群消退结束于9月底到10月上旬。两种实蝇一年发生一代,种群羽化整齐。

Population Dynamics of Dacus(Callantra)trimacula(wang)and Bactrocera(Zeugodacus)scutellatus(Hendel)in Shanxi Province

Annual monitoring was conducted on the population dynamics of Dacus(Callantra) trimacula(wang) and Bactrocera(Zeugodacus) scutelltat(Hendel) through lure-traps,holding T,Cue and Me lure agents,in Houma,Changzhi,Jiaochen,Qixian and Taiyuan in Shanxi Province.The results showed D.trimacula and B.scutellatus were dominant species.The population dynamics had similar trend at five sites.D.trimacula and B.scutellatus were first trapped from the end of June to the beginning of July every year,and then the amount of populations went up until peak appeared from the middle of August to middle of September.After that,the fly population declined and ended between the end of September and the beginning of October.The two species developed a generation each year and emerged orderly.
