Abstract

Abstract The papaya mealybug, Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae), a serious invasive pest affecting horticultural crops, was first reported in Kenya in 2016 at Kwale, Mombasa, and Kilifi Counties of the coastal region. A study was conducted to establish its identification, distribution and host ranges at the coastal region. This is the first report of P. marginatus distribution and crops attacked in Kenya. The papaya mealybug was found to infest papaya (Carica papaya), cassava (Manihot esculenta), chili pepper (Capsicum annuum), guava (Psidium guajava), mango (Mangifera indica), and eggplant (Solanum melongena) in this study. An average yield loss of 91% on papaya crop was reported in the affected farms. Only 7.2% of the farms surveyed were found to have management strategies in place against the papaya mealybug. Additional surveys should be conducted to determine pest migration and potential endemic or unintentionally introduced natural enemies.

木瓜肉虫边缘副球菌在肯尼亚的首次报告和分布1

摘要木瓜粉蚧、边缘副球菌和Granara de Willink（半翅目：拟球虫科）是一种影响园艺作物的严重入侵性害虫，于2016年在肯尼亚沿海地区的夸勒县、蒙巴萨县和基利菲县首次报告。进行了一项研究，以确定其在沿海地区的识别、分布和寄主范围。这是第一份关于P.marginatus在肯尼亚的分布和作物遭受袭击的报告。在本研究中，木瓜粉蚧感染了木瓜（Carica木瓜）、木薯（Manihot esculenta）、辣椒（Capsicum annuum）、番石榴（Psidium guajava）、芒果（Mangifera indica）和茄子（Solanum melongena）。据报道，受影响农场的木瓜作物平均产量损失91%。在接受调查的农场中，只有7.2%的农场制定了针对番木瓜粉蚧的管理策略。应进行额外的调查，以确定害虫的迁移和潜在的地方病或无意引入的天敌。

期刊介绍： The Journal of Agricultural and Urban Entomology (JAUE) (Journal of Agricultural Entomology, Jan 1984 - Oct 1998 volumes 1-15) is published under the auspices of the South Carolina Entomological Society (SCES). The Journal publishes contributions of original research concerning insects and other arthropods of agricultural and urban importance to include those affecting humans, livestock, poultry, and wildlife. JAUE is particularly dedicated to the publication of articles and notes pertaining to applied entomology, although it will accept suitable contributions of a fundamental nature related to agricultural and urban entomology.
