Scope for non-crop plants to promote conservation biological control of crop pests and serve as sources of botanical insecticides
Besides providing food and shelter to natural enemies of crop pests, plants used in conservation biological control interventions potentially provide additional ecosystem services including providing botanical insecticides. Here we concurrently tested the strength of these two services from six non-crop plants in managing cabbage pests in Ghana over three successive...Amoabeng, B. W. ; Stevenson, Philip C. ; Mochiah, B.

Information arms race explains plant-herbivore chemical communication in ecological communities
Plants emit an extraordinary diversity of chemicals that provide information about their identity and mediate their interactions with insects. However, most studies of this have focused on a few model species in controlled environments, limiting our capacity to understand plant-insect chemical communication in ecological communities. Here, by integrating information theory...Zu, Pengjuan ; Boege, Karina ; del-Val, Ek ; Schuman, Meredith C. ; Stevenson, Philip C. …

The state of the world’s urban ecosystems: What can we learn from trees, fungi, and bees?
Social Impact Statement Positive interactions between people and nature inspire behaviours that are in harmony with biodiversity conservation and also afford physical and mental health benefits. Since most people live in towns and cities, urban greenspaces are key points of influence for conservation, but also provide diverse ecosystem services. City... -

Insect pollination is important in a smallholder bean farming system
Background Many crops are dependent on pollination by insects. Habitat management in agricultural landscapes can support pollinator services and even augment crop production. Common bean (Phaseolus vulgaris L.) is an important legume for the livelihoods of smallholder farmers in many low-income countries, particularly so in East Africa. While this...Elisante, Filemon ; Ndakidemi, Patrick ; Arnold, Sarah E. J. ; Belmain, Steven R. ; Gurr, Geoff M. …

Beneficial insects are associated with botanically rich margins with trees on small farms.
Beneficial insect communities on farms are influenced by site- and landscape-level factors, with pollinator and natural enemy populations often associated with semi-natural habitat remnants. They provide ecosystem services essential for all groecosystems. For smallholders, natural pest regulation may be the only affordable and available option to manage pests. We evaluated...Arnold, Sarah E. J. ; Elisante, Filemon ; Mkenda, Prisila A. ; Tembo, Yolice L. B. ; Ndakidemi, Patrick A. …

Natural Pest Regulation and Its Compatibility with Other Crop Protection Practices in Smallholder Bean Farming Systems.
Common bean (Phaseolus vulgaris) production and storage are limited by numerous constraints. Insect pests are often the most destructive. However, resource-constrained smallholders in sub-Saharan Africa (SSA) often do little to manage pests. Where farmers do use a control strategy, it typically relies on chemical pesticides, which have adverse effects on...
