摘要

卷叶地瓜（鳞翅目：地瓜科）是一种以红薯幼叶为食的害虫，会导致严重的植物落叶。本研究旨在首次报告刚果民主共和国上加丹加省害虫的发生情况。在生长季节，在上加丹加省的十个城市进行了调查和观察，以检测是否存在A.convolvuli。在这个季节检查了五十二块红薯地。幼虫和蛹在每个城市收集，并在刚果民主共和国卢本巴希大学的实验室饲养。结果表明，该害虫发生在该省，其中卢本巴希和卡松巴莱萨的虫害率最高，分别为18.80±11.36和18.71±8.13%。每片田地和每株植物的幼虫数量最高的是卢本巴希，分别为18.80±8.04和3.80±1.48。甘薯叶害分类表明，卡松巴列萨、萨卡尼亚和卢本巴希的危害程度较高。虫害率与每片田地的幼虫数量呈正相关（R2=0.3069；t=4.705；p<0.0001），但虫害率与单株幼虫数量也呈正相关（R2=0.478；t=6.368；p<0.001）。目前的研究结果表明，旋毛虫可能对上加丹加省的红薯生产构成潜在威胁。

Occurrence of the sweet potato hornworm Agrius convolvuli (Lepidoptera: Sphingidae) in the Haut-Katanga province, Democratic Republic of the Congo

Agrius convolvuli (Lepidoptera: Sphingidae) is a pest that feeds on young sweet potato leaves causing severe plant defoliation. This study was designed to report for the first time on the occurrence of the pest in the Haut-Katanga province in DR Congo. Survey and observations were conducted during the growing season in ten cities of the Haut Katanga province to detect the presence of A. convolvuli. Fifty-two sweet potato fields were inspected during the season. Larvae and pupae were collected in each city and reared in the laboratory at the University of Lubumbashi, DR Congo. Results revealed that the pest occurs in the province with Lubumbashi and Kasumbalesa being the most highly infested with 18.80±11.36 and 18.71±8.13% of infestation, respectively. The highest number of larvae per field and per plant was recorded in Lubumbashi alone with 18.80±8.04 and 3.80±1.48, respectively. Classification of sweet potato leaf damage indicated that Kasumbalesa, Sakania and Lubumbashi had high levels of damage. Positive relationships were observed between infestation rate and number of larvae per field (R2=0.3069; t=4.705; p<0.0001) but also between infestation rate and number of larvae per plant (R2=0.4478; t=6.368; p<0.0001). The findings of the current study suggest that A. convolvuli could be a potential threat to sweet potato production in the Haut-Katanga province.

期刊介绍： The Journal of Entomological and Acarological Research (JEAR), formerly the Bollettino di Zoologia Agraria e di Bachicoltura of the Institute of Entomology of the Università degli Studi, Milano, was founded in 1928 by Remo Grandori. Thereafter, Minos Martelli and Luciano Süss hold the direction of the Journal until December 2011. In January 2012 the Editor decided for the new open-access on-line version of JEAR. The Journal publishes original research papers concerning Arthopods, but reviews, editorials, technical reports, brief notes, conference proceeding, letters to the Editor, book reviews are also welcome. JEAR has four main areas of interest: -Entomology (systematics; morphology; biology; biotechnology; agriculture, ornamental and forest entomology; applied entomology; integrated pest management; biological control; apiculture and apidology; medical, urban and veterinary entomology; etc.) -Stored product pests (biology; integrated pest management; etc.) -Insect Ecology (behaviour; biodiversity; taxonomy; plant insect interaction and ecosystems; biological control; alien species; etc.) -Acarology (systematics; morphology; biology; parasitology; control; etc.) The publication of manuscripts is subject to the approval of the Section Editor who has knowledge of the field discussed in the manuscript in accordance with the principles of Peer Review; referees will be selected from the Editorial Board or among qualified scientists of the international scientific community. Articles must be written in English and must adhere to the guidelines and details contained in the Instructions to Authors.
