    • Direct and Indirect Effect via Endophytism of Entomopathogenic Fungi on the Fitness of Myzus persicae and Its Ability to Spread PLRV on Tobacco 

      Fingu-Mabola, Junior Corneille; Bawin, Thomas; Francis, Frédéric (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-21)
      Aphids are major crop pests that are feeding on plant sap and transmitting plant viruses, thus inducing high yield losses worldwide. As chemical pesticides are decreasingly used in plant protection, fungi that cause disease to insects (entomopathogenic fungi) are one of the promising alternatives. They are commonly applied by spraying plants to protect them against herbivores. When applied, some ...

    • Does the Infectious Status of Aphids Influence Their Preference Towards Healthy, Virus-Infected and Endophytically Colonized Plants? 

      Fingu-Mabola, Junior Corneille; Martin, Clément; Bawin, Thomas; Verheggen, François Jean; Francis, Frédéric (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-11)
      Aphids (Hemiptera: Aphididae) cause significant damage and transmit viruses to various crop plants. We aimed to evaluate how the infectious status of aphids influences their interaction with potential hosts. Two aphid (Myzus persicae and Rhopalosiphum padi) and plant (Nicotiana tabacum and Triticum aestivum) species were used. The preferences of aphids towards healthy, virus-infected (Potato Leafroll ...

    • Repellent Effect of Basil (Ocimum spp) on Pea Aphid (Acyrthosiphon pisum Harris) and Potential Use in Crops 

      Yarou, Boni Barthélémy; Bawin, Thomas; Assogba-Komlan, Françoise; Mensah, Armel; Francis, Frédéric (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-30)
      Synthetic insecticides used for aphid control continue to be a threat to humans and the environment. Therefore, in order to reduce these problems, it is important to use less harmful, environmentally friendly agricultural practices. It is with this objective in mind that the choice behaviour of the pea aphid – Acyrthosiphon pisum Harris (Hemiptera: Aphididae – towards basil odors (Ocimum basilicum ...
