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. …

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 …

Mechanisms in mutualisms: a chemically mediated thrips pollination strategy in common elder
The concept of flower-feeding thrips as pollinating insects in temperate regions is rarely considered as they are more frequently regarded to be destructive florivores feeding on pollen and surrounding plant tissue. Combining laboratory and field-based studies we examined interactions between Sambucus nigra (elderflower) and Thrips major within their native range...
