Abstract: The invention provides methods and compositions for improved production of large quantities of unencapsidated double strand RNA (dsRNA) in vivo. The disclosed methods and compositions, comprising co-expression of genes encoding orotate phosporibosyl transferase, bacteriophage coat protein and dsRNA produce a significant improvement over current in vivo methods of producing unencapsidated dsRNA.

Abstract: The invention describes recombinant DNA sequences transcribed into RNA constructs capable of forming Virus Like Particles (VLPs) suitable for insect control applications.

Abstract: The invention describes recombinant DNA sequences transcribed into RNA constructs capable of forming Virus Like Particles (VLPs) suitable for insect control applications. Specifically, the disclosure provides a method for controlling target insects comprising, transforming a microbial host with a first DNA sequence comprising a gene encoding a bacteriophage capsid protein and a second DNA sequence encoding an RNA transcript comprising at least one bacteriophage pac sequence coupled to an RNAi precursor sequence, inducing the microbial host to express the first and second DNA sequences, isolating virus-like-particles (VLPs) comprising the capsid protein and RNAi precursor from the microbial host, and contacting the isolated VLPs with the target insects.

Abstract: Methods and materials for improved in vivo production of dsRNA are presented. Yields of dsRNA are significantly increased in the presence of capsid protein. The improved yield of dsRNA is not dependent on the presence of specific cognate binding sites for capsid protein associated with the dsRNA, but is dependent on capsid protein.
