摘要
目的了解皖北地区储藏柿饼中甜果螨的孳生状况,为市售储藏柿饼甜果螨的防制提供参考。方法选取皖北地区6个县临街而建的干果商店共30家,采集储藏柿饼(储藏时间≥6个月),每家采集10 g,采用直接镜检法分离柿饼中的螨类并制成玻片标本,光镜下观察形态特征,测量大小,采用与检索表和粉螨图谱比对的方法进行鉴定并分别计数。结果共采集储藏柿饼样本30份,其中23份检出甜果螨,甜果螨孳生率为76.67%(23/30);孳生密度最高为136只/g,最低为11只/g,平均孳生密度48.71只/g(14612只/300 g);共检出成螨(含若螨)12322只,幼螨1752只,螨卵538枚,各发育期的构成比依次为84.33%、11.99%及3.68%,未发现休眠体。结论皖北地区储藏柿饼存在一定程度的甜果螨污染,应采取相应措施进行有效防制,降低由螨造成的经济损失,防止人体螨病的发生。
Objective To investigate the breeding status of Carpoglyphus lactis(C.lactis)in dried persimmons in the dried fruit stores in northern Anhui Province,so as to provide reference for control of C.lactis infestation in the dried persimmons available on market.Methods Dried persimmon samples which were stored≥6 months were collected from 30 dried fruit stores by the street in 6 counties in northern Anhui Province,each store collected 10g.The mites were initially isolated from the dried persimmons by direct microscopy,and then made into slide specimens,which were observed for the morphology under a light microscope and measured of the size.Finally,the mites were identified and counted comparison with the identification index and atlas of acaroid mites.Results A total of 30 dried persimmon samples were collected,in which C.lactis was detected in 23 samples.The breeding rate of C.lactis was 76.67%(23/30),and the breeding density ranged from the highest being 36 capita to the lowest being 11 capita per gram of sample,with an average breeding density of 48.71 capita per gram(14612 capita/300 g).Totally,12322 adults(including nymphs),1752 larvae and 538 eggs were detected.The constituent ratio of C.lactis in different developmental stage was successively at 84.33%,11.99%and 3.68%for adult,larva and egg,respectively.No hypopus was detected.Conclusion The dried persimmons in the fruit stores in northern Anhui Province were contaminated by C.lactis to a certain degree,which suggests that corresponding effective prevention and control measures should be taken to reduce economic loss and incidences of acariasis.
