this carica distribution map shows that it stops at the border. makes you wonder if there are simply far fewer inaturalists in mexico. but if you go into the filter and uncheck "verifiable" you'll see several observations of carica being cultivated in mexico. i'm pretty sure that the limiting factor of carica's colonization of mexico is the desert. california is surrounded by desert, except for in the north, where the limiting factor is the cold.
i'm not sure how carica's wasp would handle florida's combination of heat, humidity and 50" of summer rain. if it survived, would it spread faster north or south? there's less rkn the further north, but then there's the issue of cold snaps.
i'm really curious if carica's wasp will be able to pollinate opposita x carica. if it can, and if the hybrid is resistant to rkn, then rkn wouldn't really limit "carica's" southerly distribution in florida.
SpiritFarmVa, yeah i think that microbiome does factor into rkn. i'm sure that rkn is a much bigger problem in a florida orange grove than in a pristine forest.
florida natural farming (fnf) has said that nematodes haven't been a problem for him, but he's never tried growing any fig trees. i wouldn't be surprised if fig trees in fnf's farm grew much better than in an orange grove or in a garden with lots of lawn. in an optimally diverse microbiome there should be quite a few critters that want to eat rkn.
4evercurious, with this same logic, seems like there should be lots of predators that want to eat nutria. and what about kudzu? nutria eats everything and anything except for kudzu? yesterday on my youtube feed a video popped up about
foraging kudzu. here in socal we have invasive mustard plant. the greens are delicious and nutritious, free and abundant, but hardly anyone harvests it. well, where are all the public service announcements (psa's)? they don't exist. but they really should.
just like it should have been the universities that 1st crossed carica with a sandpaper fig. again, there's always going to be a huge disparity between supply and demand when the demand is unknown.
next month i'm meeting with a usda researcher in miami to give him a seedling of opposita x carica. assuming he still has funding, and a job. in theory it should be relatively easy for the usda to quickly test the hybrid for rkn resistance.
i'm curious about relevant grant possibilities, assuming that they still exist.
a quick google search didn't supply any useful information about louisiana's attempt to introduce carica's wasp. was it lsu? why did it fail?
