Coffee (Coffea arabica and C. canephora) is one of the most widely traded agricultural commodities and the main cash crop in ∼80 tropical countries. Among the factors that limit coffee production, the coffee berry borer, Hypothenemus hampei (Ferrari) has been considered the main insect pest, causing losses of over U.S. $500 million dollars annually. Control of this pest has been hindered by two main factors: the cryptic nature of the insect (i.e., protected inside the coffee berry) and the availability of coffee berries in the field allowing the survival of the pest from one generation to the next. Coffee berry borer control has primarily been based on the use of synthetic insecticides. Management strategies have focused on the use of African parasitoids (Cephalonomia stephanoderis, Prorops nasuta, and Phymastichus coffea), fungal entomopathogens (Beauveria bassiana), and insect traps. These approaches have had mixed results. Recent work on the basic biology of the insect has provided novel insights that might be useful in developing novel pest management strategies. For example, the discovery of symbiotic bacteria responsible for caffeine breakdown as part of the coffee berry borer microbiome opens new possibilities for pest management via the disruption of these bacteria. Some chemicals with repellent propieties have been identified, and these have a high potential for field implementation. Finally, the publication of the CBB genome has provided insights on the biology of the insect that will help us to understand why it has been so successful at exploiting the coffee plant. Here I discuss the tools we now have against the CBB and likely control strategies that may be useful in the near future.

防治咖啡浆果虫的害虫管理策略(鞘翅目:Curculionidae:Scolytinae)

咖啡(阿拉伯咖啡C. canephora)是交易最广泛的农产品之一,也是约80个热带国家的主要经济作物。在限制咖啡产量的因素中,咖啡果蛀虫Hypothenemus hampei(Ferrari)被认为是主要的害虫,每年造成的损失超过5亿美元。该害虫的控制受到两个主要因素的阻碍:昆虫的隐秘性(即在咖啡浆果内部得到保护)以及田间的咖啡浆果的可用性使得该害虫能够一代又一代地生存。咖啡果蛀虫的防治主要基于合成杀虫剂的使用。管理策略侧重于非洲寄生虫的使用(Cephalonomia stephanoderisProrops nasutaPhymastichus coffea),真菌性昆虫病原体(Beauveria bassiana))和昆虫陷阱。这些方法产生了不同的结果。关于昆虫基本生物学的最新工作提供了新颖的见解,这些见解可能对开发新颖的害虫管理策略很有用。例如,作为咖啡果蛀虫微生物组一部分的咖啡因分解的共生细菌的发现为通过破坏这些细菌而进行有害生物管理提供了新的可能性。已经鉴定出一些具有驱避特性的化学物质,这些化学物质在现场实施方面具有很高的潜力。最后,CBB基因组的发表提供了关于昆虫生物学的见解,这将有助于我们了解为什么它在开发咖啡植物方面如此成功。在这里,我讨论了针对CBB的现有工具以及可能在不久的将来有用的控制策略。
