Field experiments were conducted using Ceranock bait station, "attract and kill" system to combat Mediterranean fruit fly, Ceratitis capitata, in citrus orchards of Baghdad and Wasit governorates, Iraq, during 2013-2014 season. Control program was implemented in six citrus orchards of mixed citrus varieties: Orange, Citrus sinensis; Mandarin, C. reticulate; Lemon, C. lemon; and Bergamot, C. aurantium. Ceranock traps 240/ha were hanged in trees of two separate orchards in each location, with third orchard served as control. Delta and McPhail traps supplied with pheromone were used to monitor Medfly population density in treated and control orchards. Results indicated that Medfly activity and presence in citrus orchards started during the first week of October coincide with the beginning of fruits ripening. The result indicated that Medfly population density in Wasit orchards was more than that of Baghdad orchards. The total trapped insects after two weeks of Ceranock were 59, 94, 142 and 205, 277, 765 adults for the firsst, second and the control orchards in the two locations, respectively. The percentage of fruit injuries were increased dramatically when fruits mature and its color turn to yellowish reaching of 35%, 56%, 21% and 32% in mandarin and orange fruits in Baghdad and Wasit orchards, respectively, compared with 3%, 4%, 4% and 5% in treated orchards, respectively. Calculated percentage of fruit damage indicated that reduction in injuries were 97% in mandarin and 96% in orange at Baghdad orchards and were 95% and 96%, respectively, in Wasit orchards. The results of this study demonstrate clearly the efficacy of Ceranock bait station, "attract and kill" system as a control measure for Medfly in citrus orchards. 相似文献

联合国粮农组织(FAO)与国际饲料工业协会(IFIF)2020年联合修订出版了《饲料行业良好管理规范(Good Practices for Feed Sector)》。此规范是为贯彻《食品法典——良好动物饲养规范(The Codex Alimentarius Code of Practice on Good Animal Feeding)》而制定的,其目的是基于“同一健康(The one health)”的方针,确保在动物性食品产业链上饲料生产供应环节的饲料安全,进而保证饲养动物的安全和动物性食品的安全、营养与多样化。文章主要介绍该规范的第二部分——基本原则与要求,包括饲料原料的采购与接收、标签、可追溯性系统、召回、适用于紧急情况的特殊条件、检查和控制程序以及加药饲料中使用的饲料添加剂和兽药等,并与我国《饲料质量安全管理规范》的相关内容进行比较和讨论,并提出一些建议。 相似文献

一、HACCP及HACCP在国际和国内应用简介HACCP是目前国际普遍认可的用于控制食品安全的先进控制体系,在食品加工行业中的应用得到国际广泛认可,美国食品和药物管理局(FDA)的资料显示,HACCP运用极大地防止了有水产品携带的各种疾病。在水产养殖方面引进并消化应用国际上先进HACCP体系,就是要在亲体-幼苗-养成-销售整个过程中确定养殖种苗、饲料和养殖过程中可能存在的危害,找出关键控制点,建立控制程序并有效监管这些控制程序。将可能发生的食品危害消除在养殖过程中,而不是靠 相似文献
