Insecticidal toxins described herein are fused toxin peptides made up of a targeting domain fused to a toxin domain. The targeting peptide generates a specific association with mosquitoes by causing the fused toxin peptide to bind mosquitoes in a way that leads to the insecticidal activity. Transgenic plants described herein are mosquitocidal by expressing an insecticidal toxin protein in nectar that includes a targeting peptide to ensure specificity against mosquitoes. These transgenic plants serve as role models for safety, since they are non-crop plants and specific to one mosquito species.
