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... -

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. …

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. …

Extracts of Common Pesticidal Plants Increase Plant Growth and Yield in Common Bean Plants
Common bean (Phaseolus vulgaris) is an important food and cash crop in many countries. Bean crop yields in sub-Saharan Africa are on average 50% lower than the global average, which is largely due to severe problems with pests and diseases as well as poor soil fertility exacerbated by low-input smallholder...Mkindi, Angela G. ; Tembo, Yolice L.B. ; Mbega, Ernest R. ; Kendal-Smith, Amy ; Farrell, Iain W. …

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... -

Bioactivity of Common Pesticidal Plants on Fall Armyworm Larvae (Spodoptera frugiperda)
The fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae) is a recent invasive pest species that has successfully established across sub-Saharan Africa where it continues to disrupt agriculture, particularly smallholder cereal production. Management of FAW in its native range in the Americas has led to the development of resistance to many... -

Phytochemical Analysis of Tephrosia vogelii across East Africa Reveals Three Chemotypes that Influence Its Use as a Pesticidal Plant
Tephrosia vogelii is a plant species chemically characterized by the presence of entomotoxic rotenoids and used widely across Africa as a botanical pesticide. Phytochemical analysis was conducted to establish the presence and abundance of the bioactive principles in this species across three countries in East Africa: Tanzania, Kenya, and Malawi....Mkindi, Angela G. ; Tembo, Yolice ; Mbega, Ernest R. ; Medvecky, Beth ; Kendal-Smith, Amy …
