Control of insect pests using rna molecules

An interfering ribonucleic acid (RNA) molecule wherein the RNA comprises at least one dsRNA wherein the dsRNA is a region of double-stranded RNA comprising annealed complementary strands, one strand of which comprises a sequence of at least 19 contiguous nucleotides which is at least partially complementary to a target nucleotide sequence within a flea beetle target gene, and (i) is at least 85% identical to at least a 19 contiguous nucleotide fragment of SEQ ID NO:

• 253-378 or SEQ ID NO:
• 616-701, or the complement thereof;
• (ii) comprises at least a 19 contiguous nucleotide fragment of SEQ ID NO:
• 253-378 or SEQ ID NO:
• 616-701, or the complement thereof;
• (iii) comprises at least a 19 contiguous nucleotide fragment of a nucleotide sequence encoding an amino acid sequence encoded by SEQ ID NO:
• 253-378 or SEQ ID NO:
• 616-701, or the complement thereof, or (iv) can hybridize under stringent conditions to a polynucleotide comprising the nucleotide sequence of SEQ ID NO:
• 253-378 or SEQ ID NO:
• 616-701, or the complements thereof, wherein the interfering RNA molecule has insecticidal activity on an insect pest, wherein the insect pest is a flea beetle of the Alticini tribe.
