what is this bug and how to kill it organically?

imagardener2(9-10)July 28, 2011

This white bug is eating my rose leaves to skeletons. also found on rudbeckia and blackberry leaves but not nearly as much. I prefer organic solution. Tried Organicide and no improvement. I've been picking them off but there are too many and they drop off or fly away.

Thanks

Denise

P.S. I tried to email jbuss@ufl.edu but it came back undeliverable.

I do not know the name of the bug, however I have had a similar beetle in my garden. I have found that walking around my garden in the morning and dropping or shaking the bug into a bucket of water to be pretty effective. I do this in the morning because their wings are wet from the dew and they can't fly away.

Good luck

From UF:
Little Leaf Notcher - Artipus floridanus (Horn)
Little leaf notcher was first reported in Florida in 1876 and is found mainly along Floridas east coast from Volusia County to the Keys. This species is the smallest of the weevils, measuring about 0.2 to 0.25 inch in length.

They are grayish-white in color, flightless, and all female
The life cycle is 60 to 120 days with 3 to 4 overlapping generations per year. The female lays an average of 1,220 eggs during her life span.

This species has a wide host range of approximately 150 plant species. These weevils disperse by crawling or by passive movement on plants or equipment.

Look for photos half way down the link.

Thank you gatormomx2

This is bad news since this weevil feeds on many, many plants including citrus and there is no known pesticide and I would only use bee-friendly anyway. It comes from Sri Lanka. Strange thing is I've gotten no new plants for many months and neighbors never buy plants for it to ride in on. Maybe it's been here for a while but in smaller numbers.

OK I read a little more and mine is NOT the Sri Lanka weevil (which has a yellow head). My critter is a FL native, they look almost identical except for the head.
They are both bad news.

Not trying to be flippant, but there's 1 organic 'treatment' that works on every insect I know of - squishing!

Spread a dab of crazy glue on a slab of concrete. (like your sidewalk or driveway)
Place bug in the gob of super glue and hold in place until it is stuck fast.
Borrow organ from church. (preferably not the church you attend)
Rent a crane to lift the organ 25 feet directly over the bug.
Have crane operator release the organ and let it fall directly on bug squishing it.
Scoop up organ parts and return them to the church.

You have now killed the bug organically.

these are small, mobile, flying or dropping to the ground bugs. Not slow like hornworms. Quite a challenge.

One good thing is that they are white and do not camouflage well. The bad thing added to above is that they seem smart. When they spot me they hide and if I move a leaf they either fly or drop and burrow FAST.

Suggestion from the Stink-bug-thread....

I tried a vaccuum and artist brush and was amazed at the number of stinkbugs I was able to eliminate QUICKLY !

A tea made of boiled habanero peppers seems to work on almost any bug.

Lou, as always, you made me laugh.

If you don't know where the Sri Lankan weevil came from, just go shopping and look at where the clothes are made. They probably came in a container with the other imported items.

I have graduated to finger crunching after several days and several dozen weevils plopping into cuppa neem mixture. Sometimes the cup works better though if they're in a place I can't reach.

ariel is right-morning is the best time but being obsessive I do it every time I'm in the garden. weevils be gone!

I do this every morning. My Loquat tree is loaded with these bugs. So I hosed them and the fall to the ground. Then I release my chickens from the chicken yard and boy what a feast they have. All my trees and shrubs are looking better for the effort. Just so you know. My grandson tried picking these off the leaves and putting them in a jar but the little buggers bite. So beware.

I have those evil weevils,too. They are very mean, so I spray them with rubbing alcohol and I'm starting to try DM earth in my yard as well.

They're in my lychee tree bad and have been for months. I squish several every day.

One thing I've found is that their instinct is to drop when cornered. So always cup your hand underneath them when grabbing at them and they will drop right into your hand. Then I just smash them. Never had one bite me.

You can also shake them out of the trees. Put down a dark colored sheet under the tree and start shaking. They drop because they're scared and then are easy to smash or hit with malathion or something else you wouldn't want to spray on everything.

Ok. Simple solution. Fill large spray bottle with: 1 cup alcohol, 2 cups water, squirt of cheap dishsoap. Spray entire lychee tree including undersides of leaves quickly before the bugs see you. Wait 5 minutes. Spray entire tree off with hose. Rinse well. Doesn't harm tree, kills bugs, alcohol evaporates, bugs die from alcohol poisoning. lol. Use non-phosphate detergent, very small amount. Makes it stick to them using the surface tension of the soap. Works great for citrus trees (small) as well. Used it on my honey tangelo. Also may want to consider spraying other nearby plants. Check weekly for new arrivals. Or you can do what my grandmother did. Peel @ 5 cloves garlic,slice up, boil in water for 2-3 minutes, pour contents at base of tree. do weekly. Just don't stand too close for a day.

You could drown the bug in crude oil that is organic? You could use arsenic that is organic.
