heres how the treatments for these critters are panning out - applied the spinosad to the stems only as directed by instructions and not totally covering plant because im worried the liquorice smelling tar like liquid with leave a bad residual taste on the buds 2 days ago...with no noticeable decline in numbers of the bug, the spinosad may indeed work in the longterm but with the destruction being wrought at such a fast pace i cannot afford to sit back for more days to see what happens without large losses to the affected plants, last nite a test was applied to 2 plants with http://ecoorganicgarden.com.au/products/pest-disease/eco-oil/ the 2 treated plants were found to harbour none of the bugs by this morning with the rest still badly infected, tonite the rest of the infected will be treated with the eco oil remedy, so the important points with this bug are - it must be eradicated asap, it wreaks damage to the pistils and growing shoots very quickly, it does not appear to have any desire for more mature budding plants, only the newly budding plants and shoots are its main targets, so far the eco oil seems to be having a good quick effect with no toxicity shown to the plants, this bug may not exist outside of australia, but fellow aussies may well bookmark this thread for future reference

i initially used this first http://mite-rid.com/ it contains neem oil as well as some other stuff, it had no effect, then the spinosad which possibly needed more time for effect...time i could not afford, now the eco oil...which seems to be fast acting in a deterrent effect

They look like dark Japanese beetles.

japanese beetles are 1/2" in length, these bugs are 1/8" fully grown

ok so after having treated all affected plants with this 2 nites ago http://ecoorganicgarden.com.au/products/pest-disease/eco-oil/ ive found 99% of the bugs have died & vanished, follow up treatment will occur in another few days, issue now is...will these affected plants recover or be permanently stunted? in a few wks i should know the outcome, note in the pic all the pistils have been eaten

Did you get that stuff online mate or locally? I think I saw something similar in bunnings or big w. I will have to check it out.
SE QLD here and the bugs are just relentless this year. Drier than normal so I'm guessing that's why.

Did you try pyrethrum on them ?
Kills most bugs and is very eco friendly there`s also a few other extracts with slightly different names that are pretty much the same thing, Spinosad normally kills any bug but you gotta be brave, in the UK you can buy it in most shops as "ant stop granules" its spinosad and sugar dry you mix it with water, if it was some stinky black stuff I doubt I`d spray the buds with it either
but Pyrethrum brakes down with sunlight lasts around 2 to 4 days where as Spinosad can last 14 days

i have tried 1 type of pyrethrum and it burnt the leaves...it must have been a concentrated type but it scared me away from it

you can buy it on ebay.com.au, compare prices as some places are more expensive than others, you can totally coat your plant with it (at sunset or nite) with no toxic effects, good stuff.
ive been growing in this area for 20yrs and never seen or heard of this bug before, then 1 wk ago its here in force, if the buds do not regrow these critters will have wiped out half my crop...in just a few days...man if you see these things dont delay & just treat your whole plants with the eco-oil, i still have not found out what these bugs are after extensive google searches, i may have to purchase a very comprehensive dedicated book on australian plant diseases & bugs

Oh its never cause any issues for me I mix it 1/2 to 2x what they say but who`s to say what brand says what on the bottle
They also do smoke bombs with it in it so just put the plant in a bag or room and fire off a smoke bomb
but you cleared them out anyway
Some poor stoner bugs are gonna be like "Man you remember that time we were living on a weed plant ? now we gotta walk all the way over there to eat weed:" lol

well checked plants first thing this morning & notice a few more of the bugs are back on the plants...only a few, understandable that they are probably everywhere on the nearby trees, so a repeat application of the eco-oil will happen again tonite, plants only need to have more mature buds then these bugs appear to have no interest, just a few weeks grace is all thats needed i hope

it would have to be a very fine net, these bugs are about the size of the large dog flea (dont know if they are outside australia) approx 3mm in length x 1mm wide

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.

And here is an amazon link. Like most foliar sprays, do it in the evening when the lights are down, especially since this stuff degrades rapidly in the sunlight.

Oh, and a few other things. ALWAYS wear a mask when spraying, you DONOT want to inhale this stuff.
And one more thing haha, chances are you aren't going to be dumping this stuff in a lake or have some runoff going into some type of pond with marine life, but just so you know.. The more you know, the better right?
This stuff isn't very toxic to mammals, but it is EXTREMELY toxic to marine life.
