摘要
茄子果实和嫩枝蛀虫(EFSB)是加纳茄子(Solanum aethiopicum L. 和 Solanum melongena L.)的一种毁灭性害虫,造成了巨大的经济损失。虽然最初被认为是在亚洲发现的 Leucinodes orbonalis Guenee 种,但最近欧洲和地中海植物保护组织的报告表明非洲没有这种害虫。然而,最近在非洲描述了 8 个 Leucinodes 物种,包括两个新物种 Leucinodes africensis sp. n. 和 Leucinodes laisalis Walker,它们是从加纳出口到英国的茄子果实中截获的。尽管据报告非洲没有 L. orbonalis,但它仍作为已知会攻击茄子的物种被列入加纳的害虫名单。为了准确确定发生在加纳南部茄子上的 EFSB 复合物的身份,我们采用了分子和形态分类工具,并在农场条件下对雄性成虫种群进行了监测。我们的研究结果表明,在茄子的嫩芽和果实中存在两种 EFSB--L. africensis 和 L. laisalis,其中 L. africensis 是优势种,广泛分布于加纳南部。值得注意的是,尽管 L. africensis 和 L. orbonalis 在生物学上截然不同,但雄性 L. africensis 会被 L. orbonalis 的信息素引诱所吸引。这项研究为正确识别侵害加纳南部茄子的 EFSB 物种提供了重要信息,对制定针对这些害虫的管理干预措施及其对国际茄子贸易的影响具有重要意义。
First report of Leucinodes africensis and Leucinodes laisalis on Solanum aethiopicum and Solanum melongena in farmer's fields in southern Ghana
The eggplant fruit and shoot borer (EFSB) is a devastating pest of eggplants (Solanum aethiopicum L. and Solanum melongena L.) in Ghana, causing significant economic losses. Although initially thought to be the Leucinodes orbonalis Guenee species found in Asia, recent European and Mediterranean Plant Protection Organization reports suggest its absence in Africa. However, eight Leucinodes species have been recently described in Africa, including two new species, Leucinodes africensis sp. n. and Leucinodes laisalis Walker, which were intercepted in eggplant fruits exported from Ghana to the United Kingdom. Despite the reported absence of L. orbonalis in Africa, it remains on the pest list of Ghana as a species known to attack eggplants. To accurately determine the identity of the EFSB complex occurring on eggplant in Southern Ghana, molecular and morphological taxonomic tools were employed, and adult male populations were monitored in on-farm conditions. Our results revealed the presence of two EFSB species, L. africensis and L. laisalis, in the shoot and fruits of eggplants, with L. africensis being the dominant species and widely distributed in Southern Ghana. Notably, L. africensis males were attracted to the pheromone lure of L. orbonalis despite the two species being biologically distinct. This study provides crucial information on correctly identifying the EFSB species attacking eggplants in Southern Ghana and has significant implications for developing management interventions against these pests and their effects on international eggplant trade.
期刊介绍:
Established in 1910, the internationally recognised Bulletin of Entomological Research aims to further global knowledge of entomology through the generalisation of research findings rather than providing more entomological exceptions. The Bulletin publishes high quality and original research papers, ''critiques'' and review articles concerning insects or other arthropods of economic importance in agriculture, forestry, stored products, biological control, medicine, animal health and natural resource management. The scope of papers addresses the biology, ecology, behaviour, physiology and systematics of individuals and populations, with a particular emphasis upon the major current and emerging pests of agriculture, horticulture and forestry, and vectors of human and animal diseases. This includes the interactions between species (plants, hosts for parasites, natural enemies and whole communities), novel methodological developments, including molecular biology, in an applied context. The Bulletin does not publish the results of pesticide testing or traditional taxonomic revisions.
