Abstract
Provided are non-propagating transgenic microalgae expressing at least one heterologous RNAi molecule. The RNAi-expressing non-propagating transgenic microalgae are used for oral delivery of the RNAi molecule to a target organism in its intact and functional form. The heterologous RNAi molecule, present within the microalgae, is characterized by being biologically active, exerting at least one specific effect on the organism consuming the microalgae or on a pathogen of said organism. In particular, the non-propagating transgenic microalgae are used as agents for biological control of animal and plant pests.
