Since its invasion in late 2016, the fall armyworm has a widespread year-round distribution within Africa where it continues to threaten cereal production, particularly maize. Most recommended control advice emphasises the need for interventions against larvae early after colonization of a new...

The non-native aquatic weed Crassula helmsii, or Australian swamp stonecrop, has become widespread and a major problem in aquatic habitats in the UK and North-West Europe, with negative impacts reported from ecologically important habitats. As very few effective traditional management tools are...

Globally, pests (invertebrates, vertebrates, pathogens, weeds) can cause estimated annual losses of between 20- 40%, but higher losses are disproportionately experienced by many low-income countries as agriculture is the mainstay of the majority of the people and of national economies. Pests pose a ...

Crop pests (weeds, insect pests and pathogens) are recognised worldwide as a serious challenge to agricultural production and threat to food security. Potential losses due to weeds, animal pests and pathogens have been reported at 34%, 18% and 16%, respectively. In monetary terms losses can be...

The rapid spread of the invasive crop pest, the fall armyworm (Spodoptera frugiperda), across Africa in recent years has attracted considerable interest, especially the effect on maize farmers. The purpose of this study is to understand and assess the economic costs of the fall armyworm invasion in ...

Vector control has been the most effective preventive measure against malaria and other vector-borne diseases. However, due to concerns such as insecticide resistance and budget shortfalls, an integrated control approach will be required to ensure sustainable, long-term effectiveness. An integrated ...

Even though many globally important tropical agroforestry crops are partially or completely dependent on insect pollination, the conditions influencing pollinator abundance in these systems are often incompletely understood. This is particularly the case for cocoa midges (Diptera: Ceratopogonidae), ...

Fall armyworm, Spodoptera frugiperda, is a crop pest native to the Americas, which has invaded and spread throughout sub-Saharan Africa within two years. Recent estimates of 20-50% maize yield loss in Africa suggest severe impact on livelihoods. Fall armyworm is still infilling its potential range...

Liriomyza huidobrensis (Blanchard) is native to South America but has expanded its range and invaded many regions of the world, primarily on flowers and to a lesser extent on horticultural product shipments. As a result of initial invasion into an area, damage caused is usually significant but not...

The appearance of fall armyworm (FAW; Spodoptera frugiperda) in Africa has caused much consternation. The UK Department for International Development commissioned CABI to compile an evidence note, which was published by CABI in September 2017. This paper is a summary of the evidence note, which...
