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.
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.
