    • The diversity of aphid parasitoids in East Africa and implications for biological control 

      Woolley, Victoria; Tembo, Yolice; Ndakidemi, Baltazar; Obanyi, Janet; Arnold, Sarah; Belmain, Steven; Ndakidemi, Patrick; Ogendo, Joshua; Stevenson, Philip (Wiley Online Library, 2021-11-18)
      BACKGROUND Hymenopteran parasitoids provide key natural pest regulation services and are reared commercially as biological control agents. Therefore, understanding parasitoid community composition in natural populations ...
    • Elements of agroecological pest and disease management 

      Belmain, Steven; Tembo, Yolice; Mkindi, Angela; Arnold, Sarah; Stevenson, Philip (University of California Press, 2022-06-01)
      The development of large-scale monocropped agrisystems has facilitated increased problems with pests and diseases, perpetuating the reliance of farmers on synthetic pesticides. The economic success of synthetic inputs ...
    • Extracts of Common Pesticidal Plants Increase Plant Growth and Yield in Common Bean Plants. 

      Mkindi, Angela; Tembo, Yolice; Mbega, Ernest; Smith, Amy; Farrell, Iain; Ndakidemi, Patrick; Stevenson, Philip; Belmain, Steven (MDPI, 2020-01-23)
      Common bean () 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 ...
    • Invasive weeds with pesticidal properties as potential new crops 

      Mkindi, Angela; Mpumi, Nelson; Tembo, Yolice; Stevenson, Phillip; Ndakidemi, Patrick; Mtei, Kelvin; Machunda, Revocatus; Belmain, Steven (Elsevier, 2017-12-30)
      Plants with pesticidal properties have been investigated for decades as alternatives to synthetics, but only a handful have been commercialised and developed as non-food cash crops. One of the reasons why pesticidal plants ...

    • Pesticidal Plant Extracts Improve Yield and Reduce Insect Pests on Legume Crops Without Harming Beneficial Arthropods 

      Tembo, Yolice; Mkindi, Angela; Mkenda, Prisila; Mpumi, Nelson; Mwanauta, Regina; Stevenson, Philip; Ndakidemi, Patrick; Belmain, Steven (Original Research, 2018-09-28)
      In the fight against arthropod crop pests using plant secondary metabolites, most research has focussed on the identification of bioactive molecules. Several hundred candidate plant species and compounds are now known ...
    • Phytochemical Analysis of across East Africa Reveals Three Chemotypes that Influence Its Use as a Pesticidal Plant. 

      Mkindi, Angela; Tembo, Yolice; Mbega, Ernest; Medvecky, Beth; Kendal-Smith, Amy; Farrell, Iain; Ndakidemi, Patrick; Belmain, Steven; Stevenson, Philip (MDPI, 2019-12-12)
      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 ...
