Abstract

ABSTRACT Ectomyelois ceratoniae (Zeller) is a cosmopolitan pest that affects many crops worldwide. The present study was performed to refine our knowledge about density and damage of this pest on Navel oranges in northern Tunisia and to evaluate the effectiveness of four alternative methods including, cultural control, mass trapping, Trichogramma cacoeciae (Marchal) releases and mating disruption. Results showed that E. ceratoniae populations increased from April to November. All trials were effective in decreasing E. ceratoniae populations on citrus fruits. The most effective management was mating disruption combined with T. cacoeciae release (30,000 Trichogramms/ha), with a reduction rate of E. ceratoniae of 62.8% after treatment. Mass trapping using delta traps combined with Trichogramma releases (25,000 T/ha) may be a promising alternative for limiting E. ceratoniae populations. It has also been shown that a density of 10 delta traps/ha can reduce the infestation rate of E. ceratoniae. Furthermore, control by successive T. cacoeciae releases at a density of 20,000 T/ha shows its effectiveness. Our results for improving management of E. ceratoniae in citrus orchards are highlighted and discussed herein.

突尼斯柑桔园对Ectomyeloïs褐螟不同防治策略的效果研究

ceratoniae (Ectomyelois ceratoniae, Zeller)是一种世界性害虫，危害世界各地的多种作物。本研究旨在完善我们对突尼斯北部脐橙这种害虫的密度和危害的认识，并评估四种替代方法的有效性，包括培养控制、大规模诱捕、赤眼蜂(Marchal)释放和交配中断。结果表明:4 - 11月蠓种群数量呈上升趋势;所有试验均能有效减少柑橘类水果上的角蠓种群。干扰交配联合放生(3万头/公顷)是最有效的处理方法，处理后角蠓的减少率为62.8%。利用三角捕集器结合赤眼蜂释放(25000吨/公顷)进行大规模捕集可能是限制角蠓种群的一种有希望的替代方法。研究还表明，10个三角陷阱/公顷的密度可以降低角蠓的侵染率。以2万T/ hm2的密度连续放生，防治效果明显。本文重点讨论了我们在柑桔果园中改善蠓管理方面的研究成果。

期刊介绍： Oriental Insects is an international, peer-reviewed journal devoted to the publication of original research articles and reviews on the taxonomy, ecology, biodiversity and evolution of insects and other land arthropods of the Old World and Australia. Manuscripts referring to Africa, Australia and Oceania are highly welcomed. Research papers covering the study of behaviour, conservation, forensic and medical entomology, urban entomology and pest control are encouraged, provided that the research has relevance to Old World or Australian entomofauna. Precedence will be given to more general manuscripts (e.g. revisions of higher taxa, papers with combined methodologies or referring to larger geographic units). Descriptive manuscripts should refer to more than a single species and contain more general results or discussion (e.g. determination keys, biological or ecological data etc.). Laboratory works without zoogeographic or taxonomic reference to the scope of the journal will not be accepted.
