Summer means vacation time, and nothing says, “Welcome to paradise!” quite like a palm tree. Though it’s home to only one native species, California has nonetheless adopted the palm as a quintessential icon.
But a new snake in California’s palm tree-lined garden may soon put all that to the test. Dozens of palms in San Diego’s Sweetwater Summit Regional Park, about 10 miles from the Mexican border, are looking more like sad, upside-down umbrellas than the usual bursts of botanical joy.
The offender is the South American palm weevil, a recent arrival to the U.S. that’s long been widespread in the tropics. Large, black, shiny, and possessed of an impressive proboscis (nose), the weevil prefers the king of palms, the Canary Island date palm, also known as the “pineapple palm” for the distinctive way it’s typically pruned.
A palm tree is basically a gigantic cake-pop, an enormous ball of veggie goodness on a stick. The adult female palm weevil uses her long snout to drill tunnels into that goodness—known to science as the “apical meristem” and to your grocer as the “heart” of the palm—where she lays her eggs.
When her larvae hatch, their food is all around them. And they start to eat.
If the South American palm weevil consolidates its foothold in California, then the worst might still be to come. While these weevils generally stick to the Canary Island palms, they can harbor a parasitic worm that causes red-ring disease—a fatal infection that can strike almost any palm, including the state’s precious native, the California fan.
--- Where do South American Palm Weevils come from?
Originally, Brazil and Argentina. They’ve become common wherever there are Canary Island Palm trees, however, which includes Europe, the Mediterranean, the Middle East.
--- How do they kill palm trees?
Their larvae eat the apical meristem, which is the sweet part of the plant sometimes harvested and sold commercially as the “heart of palm.”
--- How do you get rid of them?
If the palm weevils infest a tree, it’s very hard to save it, since they live on the inside, where they escape both detection and pesticides. Neighboring palm trees can be sprayed for protection.

Greetings! I'm the producer of this episode of Deep Look. I wish we could have brought it to you in smell-o-vision. The stink of the infested tree filled a whole city block, and got all over my shirt. Leave us your questions and comments! And visit Anna at Gross Science, too. —Elliott

I know they are a pest and all but I like beetles ALOT!! N would LOVE to get my hands on a few to breed. No worries ANY beetles I breed I do NOT allow out of the beetle room. And even when they die I freeze them for a week before throwing them out just in case.
Yes we do eat them, we have one of those bug but the head is smaller and body is fatter, and they live in smaller palm trees only five feet at tallest. only one larva in each plant. It is one of the forage-able food in the forest. Some restaurants in the city sell them for $1 per Larva, they are fired, not eaten raw, they are kinda a delicacy actually.
I wish I could get my hands on those larvae,....
I have had those when I was a child....but its so hard to get them now...as if like they are just vanishing.
I kid you not when I tell you....these bugs are pretty delicious...
In Portugal we have been having the exact same problem ... the only diference is that the weevils are orange and not black ... The good thing though is that we’re way closer to Canary Islands to export them again ...
I know how to put pesticides on every tree get a plane that pours water the plane that is used to extinguish (sry maybe wrong spelling) fire but do not put water put pesticides and boom done just pour it at some parts of the world and boom done
The larvae are food! Full of protein! I would eat them fried along with some grasshoppers... I've heard some restaurants that serve exotic foods buy them larvae $50 bucks a pound .Its sort of like eating a land shrimp.

Men predominantly suffer from this health condition, particularly male pattern baldness and early onset hair loss from age 20-40.
However, there are ways to slow down the rate of male hair loss or baldness, and even stimulating the hair follicles to reproduce hair. A few home remedies for hair loss and baldness issue are discussed below.
