Abstract

The white mango scale, Aulacaspis tubercularis Newstead (Hemiptera: Diaspididae) is an exotic pest that causes important economic damage in the Spanish mango crops. Prospecting for potential natural enemies, the parasitic wasp Arrhenophagus chionaspidis Aurivillius (Hymenoptera: Encyrtidae) was first detected attacking immature male stages of A. tubercularis in Tenerife (Canary Islands, Spain) in 2022. Still, its influence on pest populations was not evaluated. This endoparasitoid was identified by its morphological characteristics and characterized for the first time by DNA barcoding of adult females using partial (651 bp) mitochondrial cytochrome oxidase 1 (mtCOI) gene (Genbank accession number OQ646824). Its potential utilization as biological control agent of A. tubercularis in mango crops is discussed. Therefore, further studies need to be conducted about its biology, population dynamics and rate of natural parasitism for the development of effective biological control strategies of A. tubercularis in mango.

加那利群岛首次报告 Arrhenophagus chionaspidis Aurivillius（膜翅目：Encyrtidae）对 Aulacaspis tubercularis Newstead（半翅目：Diaspididae）的危害

白芒果鳞Aulacaspis tubercularis Newstead（半翅目：Diaspididae）是一种外来害虫，对西班牙芒果作物造成了严重的经济损失。为了寻找潜在的天敌，2022 年在特内里费岛（西班牙加那利群岛）首次发现了寄生蜂 Arrhenophagus chionaspidis Aurivillius（膜翅目：Encyrtidae），它攻击未成熟的雄性 tubercularis。但并未评估其对害虫种群的影响。通过其形态特征确定了这种内寄生虫，并首次使用部分（651 bp）线粒体细胞色素氧化酶 1（mtCOI）基因（Genbank登录号 OQ646824）对成年雌虫进行了 DNA 条形码鉴定。讨论了它作为芒果作物中结核杆菌生物防治剂的潜在用途。因此，需要对其生物学特性、种群动态和自然寄生率进行进一步研究，以制定有效的芒果中结核杆菌生物防治策略。

期刊介绍： Phytoparasitica is an international journal on Plant Protection, that publishes original research contributions on the biological, chemical and molecular aspects of Entomology, Plant Pathology, Virology, Nematology, and Weed Sciences, which strives to improve scientific knowledge and technology for IPM, in forest and agroecosystems. Phytoparasitica emphasizes new insights into plant disease and pest etiology, epidemiology, host-parasite/pest biochemistry and cell biology, ecology and population biology, host genetics and resistance, disease vector biology, plant stress and biotic disorders, postharvest pathology and mycotoxins. Research can cover aspects related to the nature of plant diseases, pests and weeds, the causal agents, their spread, the losses they cause, crop loss assessment, and novel tactics and approaches for their management.
