Hi everyone. Having read through the excellent website of @Widowman10, I have a couple of questions regarding the venom of Latrodectus sp.
The LD50 values are quoted by Widowman10 as being:
Latrodectus geometricus = .43 mg/kg (IV) & .223 mg/kg (IP)
Latrodectus hesperus = .84 mg/kg (IV)
Latrodectus mactans = 1.39 mg/kg (IV) & .90 mg/kg (SC)
Latrodectus bishopi = 2.2 mg/kg (could be IP)
Latrodectus variolus = 1.8 mg/kg (IP)
Based on the figures above does Latrodectus geometricus have the most potent venom of the Northern American Latrodectus species, but because the yield of venom is considerably lower than other Latrodectus species the bite of Latrodectus geometricus is not usually medically significant to humans?
Which of the Northern American Latrodectus species is considered to be the most dangerous to humans, taking into account both the potency and yield of the venom? I've read conflicting answers to this question from varying online sources so I imagine opinion varies on this topic.
Thanks for your help.
