Venom composition image
Figure 1: Composition of L.intermedia venom, studied at the transcriptomic level (Gremski et al., 2010). The venom contains the following families: LiTx3-related, LiTx, peptidase M12A (astacin-like metalloprotease), SicTox (arthropod phospholipase D) , neurotoxin-Magi 3-like,serine protease, TCTP (translationally controlled tumor protein) , allergen, hyaluronidase (glycosyl hydrolase 56) and serine protease inhibitor.
Clinical Effects, Treatment, Antivenoms See the Clinical Toxinology Resources Website.
Lethal dose LD(50) is 0.48 mg/kg when injected into mice (Barbaro et al., 1996).
LD(50) is 0.34 mg/kg by subcutaneous injection into mice (Dias-Lopez et al., 2010).
LD(50) is 1.80 ± 0.30 μg/g when injected into lepidoperan Agrotis ipsilon larvae (de Castro et al., 2004).
LD(50) is 1.39 ± 0.34 μg/g when injected into lepidoperan Diatraea saccharalis larvae (de Castro et al., 2004).
LD(50) is 1.92 ± 0.71 μg/g when injected into lepidoperan Spodoptera cosmioides larvae (de Castro et al., 2004).
LD(50) is 1.90 ± 0.11 μg/g when injected into lepidoperan Spodoptera frugiperdalarvae larvae
(de Castro et al., 2004).
