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. …

Knowledge gaps among smallholder farmers hinder adoption of conservation biological control
Conservation biological control uses habitat management to enhance the survival and impact of arthropod natural enemies for pest control. Its advantages are that it relies on native or established invertebrate populations that are adapted to local agricultural ecosystems and conditions. We surveyed 300 farmers in three agro-ecological zones of Kilimanjaro... -

Multiple ecosystem services from field margin vegetation for ecological sustainability in agriculture: scientific evidence and knowledge gaps
Background Field margin and non-crop vegetation in agricultural systems are potential ecosystem services providers because they offer semi-natural habitats for both below and above ground animal groups such as soil organisms, small mammals, birds and arthropods that are service supplying units. They are considered as a target area for... -

Field Margin Vegetation in Tropical African Bean Systems Harbours Diverse Natural Enemies for Biological Pest Control in Adjacent Crops
Non-crop vegetation around farmland can be valuable habitats for enhancing ecosystem services but little is known of the importance of field margins in supporting natural enemies of insect pests in tropical agriculture. This study was conducted in smallholder bean fields in three elevation zones to assess the importance of field...Mkenda, Prisila A. ; Ndakidemi, Patrick A. ; Stevenson, Philip C. ; Arnold, Sarah E.

Characterization of Hymenopteran Parasitoids of Aphis fabae in an African Smallholder Bean Farming System through Sequencing of COI ‘Mini-Barcodes’
Parasitoids are among the most frequently reported natural enemies of insect pests, particularly aphids. The efficacy of parasitoids as biocontrol agents is influenced by biotic and abiotic factors. For example, hyperparasitoids can reduce the abundance of the primary parasitoids as well as modify their behavior. A field study was conducted... -

Enhancing knowledge among smallholders on pollinators and supporting field margins for sustainable food security
Agro-ecological intensification (AEI) harnesses natural processes, such as pollination, that support sustainable crop production and can buffer against future food security risks. However, the transition from conventional agriculture, which relies on inputs that can damage natural ecosystem processes, to more sustainable food production under AEI, is knowledge-intensive. Here, we investigated...Elisante, Filemon ; Ndakidemi, Patrick A. ; Arnold, Sarah E.J. ; Belmain, Steven R. ; Gurr, Geoff M. …
