has anyone seen these insects before?

I've used pyrethrin based pesticides in the past for serious white fly infestations. This is some really KILLER shit, and I would only recommend using it if you have a serious infestation. I'll post some info for you and a link for some good stuff that won't be harsh on the ladies. Gotta be careful with what kind of pyrethrum/pyrethrin you use.

Where does pyrethrum come from?

Pyrethrum is found in the Chrysanthemum plant, Chrysanthemum cinerariaefolium. Pyrethrum is found at particularly high concentration within flower structures known as achenes which are located in the flowerhead of the Chrysanthemum.



What are the differences between pyrethrum, pyrethrins and pyrethroids?

Pyrethrum is the extract from the flowerhead of the Chrysanthemum plant. The six esters known collectively as pyrethrins are found within the pyrethrum extract. The pyrethrins are the active ingredient in pyrethrum that kills insects.

Pyrethroids are synthetically produced compounds with a chemical structure that is similiar to the structure of one of the pyrethrin esters. They kill insects by a similiar mode of action, but do not come from flowers.



How does pyrethrum kill insects?

Pyrethrum induces a toxic effect in insects when it penetrates the cuticle and reaches the nervous system. The pyrethrins that compose pyrethrum bind to sodium channels that occur along the length of nerve cells. Sodium channels are responsible for nerve signal transmission along the length of the nerve cell by permitting the flux of sodium ions. When pyrethrins bind to sodium channels, normal function of the channels is obstructed thereby resulting in hyperexcitation if the nerve cell and, consequently, a loss of function of the nerve cell. The shutdown of the insect nervous system and insect death are most often the consequences of insect exposure to pyrethrins.



What happens to pyrethrum in the environment?

Pyrethrum does not persist for a long time in the environment. The active chemicals in pyrethrum, pyrethrins, are degraded by high temperature and UV light.



What kind of insects can be controlled with pyrethrum based products?

Pyrethrum is a broad spectrum insecticide. Meaning it will affect a wide range of insects; including beneficials.



How long have pyrethrins been used for insect control?

Pyrethrins have been used in insect control for more than 160 years.



Will pyrethrum/ins degrade or become less potent during storage?

Most products are packaged in containers that do not let UV light through, and indicate they should be stored in a cool, dry place. Under these conditions most products should maintain their potency for a couple of years. If the product is subjected to high temperature or UV light, there can be some degradation of the pyrethrins. As with most products, you should only purchase what you need, and for best results use it within the season it is purchased.



How safe is Pyrethrum?

Pyrethrum has been extensively studied for its effects on people and the environment. Like all insecticides, pyrethrum is used to have a toxic effect on insects. Thus it is not correct to say that pyrethrum is "safe." At the same time, we are confident that pyrethrum has a very good toxicity profile. For mammals, doses that elicit toxic reactions are significantly larger than the exposures people typically experience in using pyrethrum based products.
appreciate this info, i bought a can of pyrethrum spray from a garden centre about 10yrs ago, i sprayed the leaves at nite to deter some mites...the next day the leaves were burnt off the plant, this scared me away from pyrethrum sprays all this time...so i approach this substance with caution now...if i find a good recommended brand growers here(weed growers) use safely then i will consider it...otherwise im a bit wary of it

latest report on the 'flea beetle' is - after 2 applications of the eco-oil 4 days apart the beetle is all but gone, i found 2 alive & 5 dead ones on the plants, i will repeat the eco-oil treatment in about 3 more days to give as much respite to the plants as possible, good news also the damaged small buds are sprouting new pistils, i had fears they would be stunted permanently, like what happened some years ago after an invisible mites aka broad mites invasion, will post some pics of the new pistil growth tomorrow, the good thing too with this bug is - it shows no interest in more mature buds, so hopefully in the next week the buds will be large enough & be 'distasteful' to them

ill get some and try it thanks, need everything we can get as an arsenal against the bugs
You'll be happy with this stuff, I can vouch for it, used it all last year even in flowering unfortunately, cause i had a major white fly infestation.

The pipernoyl bonoxide or whatever thats also in that spray increases the toxicity of the pyrethrins or somethin like that, makes it more effective. Has a very chemically smell tho, doesn't leach into the taste of buds though.

I could only see a few of those bugs in the picture, there pretty big which is good if you ask me, instead of having 1000s of lil aphids or whiteflies hiding beneath the forest.

Don't wanna double post, so I'ma add a few thing to this post, which can be helpful for future grows.

Praying mantis egg sacks are in season right now bro, you should consider loadin up. I just picked up 5 egg sacs on ebay for about 14$ after shipping. You get about 50-200 praying mantis to each egg and they are legit bosses when it comes to killin other insects.

Start neem treating your plants everytime as a prevention. When they're maybe 3-4 weeks old start spraying them all over, under the leaves, etc. every 3 days for 3 weeks straight and do it once more later on throughout the grow (outdoors).

Another few good pesticides you should keep in hand is some monetery bay's insect killer (spinosad) and of course some BT for little caterpillars, which I assume you already have that one, atleast i hope.

Sure thing man. An ounce of prevention is worth a pound of cure haha.

Preventing is definitely the way to do it, cause outdoors you will always run into pests. Two favorite things in the world is neem oil and praying mantis's haha.. Not too much of a fan for ladybugs, they never happen to stay on the ladies for long, but I've had a single praying mantis grow from a baby to a full grown women pregnant 4-5 months later into the season in my garden (assuming it was the same one haha).

Well congrats on taking care of the problem, hopin those dam critters don't come back lol.

thanks very much, sounds great with the mantis...remember the horror movie 'mantis'? lol...they are the apex predator for sure, excellent having them stay around for soo long, no doubt have pet names for some of them now?

well it looks like the flea beetles have packed their little bags & moved on, could not see 1 this morning, plants are recovering with new pistil growth so it looks like a win against the horrors, they have no appetite for more mature buds, or for the eco-oil, 2 applications were applied 4 days apart, some pics of the recovering buds, thanks for helpful advice offered by the good hearts here....:peace:IMG_2535.JPG IMG_2536.JPG

thanks Bear420, lucky to find the remedy quickly, otherwise i fear they would have been permanently stunted in a short amount of time
