LqhIT2 is a 61 amino acid-long scorpion depressant toxin from L. quinquestriatus hebraeus. Although the scorpion is dangerous to humans, LqhIT2 is not. LqhIT2 shows a high preference for insect voltage-gated sodium channels and is totally harmless to mammals (Karbat et al., 2007; Zlotkin et al., 1991).

LqhIT2, an insect-specific toxin from Leiurus quinquestriatus hebraeus

LqhIT2 is a 61 amino acid-long scorpion depressant toxin from L. quinquestriatus hebraeus. Although the scorpion is dangerous to humans, LqhIT2 is not. LqhIT2 shows a high preference for insect voltage-gated sodium channels and is totally harmless to mammals (Karbat et al., 2007; Zlotkin et al., 1991).

Usage and Biology

Since LqhIT2 is only toxic to insects, it is a good choice for pesticides. To improve the efficiency and effectiveness of Metarhizium anisopliae as a fungal biopesticide, we chose to introduce LqhIT2 into the fungus. LqhIT2 significantly improved the virulence of M. anisopliae against pests.
