Arthropods intercepted on fresh Chrysophyllum fruit imported into England from Ghana and Nigeria.

Abstract

Fresh Chrysophyllum sp. fruit is occasionally imported into England from Ghana and Nigeria. This trade is of interest due to the relatively large numbers of arthropod species (40) detected on a small number (18) of samples of fruit examined. This high level of infestation is due in part to the practice of collecting the fruit once it is ripe and fallen to the forest floor. The majority of arthropods found were non-native plant pests including four quarantine pests for the EU: Bemisia tabaci, Ceratitis anonae, Ceratitis punctata and Parasaissetia nigra. The most frequent and abundant species was the scale insect Stictococcus sjostedti, a polyphagous pest that occurs widely in tropical Africa. The potential phytosanitary risk to the U.K. horticultural industry posed by this trade is discussed and concluded to be negligible.
