Projects

The RnAPhidS project develops innovative RNA-based plant protection solutions for a sustainable and environmentally friendly cultivation of winter oilseed rape. The aim is to replace chemical-synthetic insecticides with highly specific, biodegradable RNA sprays. These exploit the natural mechanism of RNA interference (RNAi) to selectively silence genes in target pest insects.

The project focuses on two major pests: the aphid Myzus persicae and the cabbage stem flea beetle Psylliodes chrysocephala, both of which are increasingly developing resistance to conventional active substances. Through the development of tailored double-stranded RNA (dsRNA) molecules and optimized formulations, the project aims to enable effective, stable, and field-applicable use under open-field conditions.

The project makes a significant contribution to sustainable agriculture by reducing impacts on soil and water, protecting biodiversity, and strengthening integrated pest management strategies. At the same time, the flexible RNA-based approach opens new perspectives for application across different crops and against a wide range of insect pests.

This collaborative project between Kenyatta University and the University of Jena, funded by the Alexander von Humboldt Foundation, aims to develop innovative and environmentally friendly strategies to control the insect vector Maiestas banda, which transmits Napier grass stunt (NGS) disease in East Africa. The project focuses on semiochemical-based “attract-and-kill” systems that lure pests and enhance their control through natural enemies such as ants and spiders.

A key objective is the identification of plant-derived volatile compounds (allelochemicals) that influence both the pest and its natural predators. These compounds will be formulated into effective blends and implemented in field-based trapping devices that can be directly used by smallholder farmers.

By integrating fundamental research with applied agricultural solutions, the project also emphasizes capacity building through training programs, particularly targeting women and youth. Ultimately, the approach aims to sustainably improve fodder production and strengthen the livelihoods and resilience of smallholder farmers across East Africa.
