中文摘要:
【目的】 对北京市密云区种植园内发现的危害草莓的新害虫进行种类鉴定,掌握该虫的危害情况与发生规律,采取有效措施进行防控。【方法】 通过形态学和分子生物学手段进行物种鉴定,观察该虫的危害特点,在受害园区交替喷施乙基多杀菌素和苏云金杆菌进行防控。【结果】 形态和分子鉴定结果表明该害虫为欧洲辣椒螟Duponchelia fovealis(鳞翅目:草螟科:斑野螟亚科)。该虫原产南欧和地中海东部地区,目前已经扩散至除澳大利亚大陆外的世界主要大陆,在我国尚属首次报道,是入侵我国的一种新害虫。欧洲辣椒螟食性广,寄主植物包括草莓、辣椒、玉米、绿萝等65科的140多种植物,幼虫可取食植物嫩叶、茎和果实。在北欧和北美地区常对设施栽培的作物和花卉以及露地种苗造成危害。幼虫常隐藏于土壤中,不易被发现。在我国首次发现该虫的北京市密云区东邵渠镇园区内,约35%的草莓植株受害。通过交替喷施60 g/L乙基多杀菌素悬浮剂30 mL/667 m2(2 000倍液)和苏云金杆菌可湿性粉剂G033A 32 000 IU/mg 100 g/667 m2(600倍液),受害园区内的种群得到控制。【结论】 欧洲辣椒螟已入侵我国,建议有关部门加强检疫和监测,若发现需尽早采取有效防控措施,以减轻该虫造成的危害。
英文摘要:
[Aim] To identify a new pest damaging strawberries
on a farm in Miyun District, Beijing, understand its impact and occurrence, and
implement effective control measures. [Methods] The species was identified through
morphological and molecular identification and the damage caused by it was
observed. A prevention and control experiment was carried out by alternately
spraying spinetoram SC and Bacillus thuringiensis at the affected
farm. [Results] The pest was the
European pepper moth, Duponchelia fovealis (Lepidoptera: Crambidae: Spilomelinae).
Native to Southern Europe and the Eastern Mediterranean, this moth has now
spread to all major continents except Australia. This is the first report of
this species in China as an invasive pest. Larvae of this pest are polyphagous
and feed on over 140 crops from 65 plant families, including strawberry,
pepper, and golden pothos. The larvae feed on the tender leaves, stems,
and fruits of plants. D. fovealis often attacks crops and flowers grown
in greenhouses and outdoor nurseries in Northern Europe and North America.
Larvae are often hidden in the soil, making them difficult to detect. On the
farm on which this pest was first reported in China, about 35% of strawberry
plants had been damaged by it. The population of this moth in Miyun was
successfully controlled by alternately spraying 60 g/L spinetoram SC
(equivalent to 30 mL/667 m2; 2 000-fold dilution) and Bacillus thuringiensis wettable powder G033A 32 000 IU/mg 100 g/acre (600-fold
dilution). [Conclusion] The European
pepper moth is now present in China.
Therefore, it is recommended that the relevant authorities strengthen
quarantine and monitoring measures for this pest. If further outbreaks are
detected, effective prevention and control measures should be implemented
promptly to mitigate damage to agricultural crops and horticultural plants.
