“…Another factor that could also determine likelihood of a species being present or absent in a given state is time since arrival and establishment in the United States. However, the reliability of these type of data is notoriously poor (invaders can remain undetected for many years and reporting varies with commodity, surveillance systems, economic significance, feeding ecology, taxonomy and so on) 32 , making systematic analysis difficult. Beyond enabling us to generate likelihood lists for each of the US states, as mentioned in the methods, those regions that are closest together in a SOM, and in particular that share the same neuron, are most similar to one another 21,22,24,33 .…”

“…To date, nonnative insects, weeds and disease organisms, together with climate change, are considered to be the main drivers for biodiversity loss at global scale (Mooney and Hobbs 2000) with growing world trade and increased travel accelerating the rate of new introductions (Josling et al 2003). The proportion of insect pests in reported introductions is substantial, but lower than the one of weeds and pathogenic organisms (Pimentel et al 2005, Waage et al 2009). Because of complex intertrophic and ecosystem-interactions, the ecological impact of invasive insects is far-reaching and generally complex to assess (Kenis et al 2009).…”

Bactrocera invadens(Diptera: Tephritidae), a New Invasive Fruit Fly Pest for the Afrotropical Region: Host Plant Range and Distribution in West and Central Africa

In 2003, the invasive fruit fly Bactrocera invadens Drew, Tsuruta & White (Diptera: Tephritidae) (Drew et al. 2005), of possible Sri Lankan origin, has been detected in the East and about 1 yr later in West Africa. In regular surveys in Benin and Cameroon covering 4 yr, samples from 117 plant species across 43 families have been obtained. Incubation of field-collected fruits demonstrate that in West and Central Africa (WCA) B. invadens is highly polyphagous, infesting wild and cultivated fruits of at least 46 species from 23 plant families with guava (Psidium spp.), mango (Mangifera spp.), and citrus (spp.), and the wild hosts tropical almond (Terminalia catappa L.), African wild mango (Irvingia gabonensis (Aubry-Lecomte) Baill.), and sheanut (Vitellaria paradoxa C.F.Gaertn.) showing the highest infestation index. B. invadens occurs in 22 countries of WCA with new records for Angola, Central African Republic, the Congo, DR Congo, Equatorial Guinea, Gabon, Gambia, Guinea Bissau, Mali, Mauritania, Niger, and Sierra Leone. Overall, the pest has spread across a North-South distance of ≍5,000 km representing a contiguous area of >8.3 million km(2) within WCA. B. invadens has adapted to a wide range of ecological and climatic conditions extending from low land rainforest to dry savanna. Because of its highly destructive and invasive potential, B. invadens poses a serious threat to horticulture in Africa if left uncontrolled. Moreover, the presence of this quarantine pest causes considerable restrictions on international trade of affected crops.

“…Quarantines need to be strengthened on a worldwide basis to counter the increased spread and dissemination of emerging infectious diseases. However, owing to limited national and regional phytosanitary capacity and the impetus to remove trade barriers, tropical countries are vulnerable to emerging infectious plant diseases (135).…”

The tropics produce a range of fruit from tree crops that cannot be grown in colder climates. Bananas, mangos, several nuts, spices, coffee, and cacao are widely traded and much sought after around the world. However, the sustainable production of these tropical tree fruit crops faces significant challenges. Among these, losses due to pests and diseases play a large part in reducing yields, quality, and profitability. Using bananas and cacao as key examples, we outline some of the reasons fungal and oomycete diseases cause such significant losses to tropical tree crops. Cultivation of monocultures derived from limited genetic diversity, environmental conditions conducive for disease development, high levels of disease incidence and severity, a lack of disease resistance in planting materials, shortages of labor, and inadequate infrastructure and investment pose significant challenges, especially for smallholder producers. The expansion of travel and trade has given rise to emerging infectious plant diseases that add further insecurity and pressure. We conclude that holistic actions are needed on multiple fronts to address the growing problem of disease in tropical fruit tree crops.
