I have visitors on some of my tomato plants. Anyone want to have a go at IDing them for me please?
That is my thumb nail for some idea of size. Obviously there are babies there too. The markings are very regular, not all over the place at all.
Hmm, seems like they are green vegetable bugs, but early stages. I think I did see an adult around the other day. I’ll keep knocking them off.

Juvenile green shield bugs. Easier to kill when they are young and clustered. A real pain to have on tomates. They will ruin the whole crop.

If sprayed with pyrethrum when young, it may kill them. Virtually nothing kills the adults. Pyretthrum will damage young growth on pants so this gets problematic.
Some say that homeopathy works. chuck them in a blender and spray them back on.
nice pics

Doesn’t white oil work?

No.
I wonder why. Do you have any idea?

There’s no getting around it. Sometimes after everything you’ve tried has failed, your only option for removal is with the use of pesticides. That being said, stink bug elimination is difficult since they are resistant to most common pesticides. Their waxy-like coating makes it hard for poisons to penetrate. However, there are a few options you can try.
Look for organic pesticide methods of stinkbug control first. These include:
Neem oil Insecticidal soap Pyrethrin RotenoneMichael V said:

Hard exoskeleton.
They still have to breathe somehow. Through spiracles like other insects, I’d imagine. I’ll check. And that’s how white oil works – by blocking the spiracles, isn’t it?

Oh, like WD-40 then?

Tell me more.
And yes, that’s how white oil works, by blocking an insect’s breathing tubes (spiracles). And hemiptera have spiracles.
White Oil spray.
1 1/2 half cups water
1 Cup Cooking Oil
1 Tsp Detergent
Mix all ingredients in a blender.
Spray ratio 1/50
This works on most of these type pests
dumb’s back from the stock rounds, previous to that did some security updates to daddy’s computer
coffeed just now, few saladas with vegemite on, and lady’s making fried eggs on toast
for more information please don’t hesitate to ask

Yes it is how white oil or soapy water or milk sprays work but shield bugs seem almost unkillable other than by squashing and even thta isn’t easy. The best time to contriol them and maybe white oil could help here is when they are in the early nymph stages.

A couple of different organic growers methodology. Though this first one is mainly about the citrus bugs there are good ideas from sucking them up with vacuum cleaner to full fat milk, cheap cooking oil and dishwashing liquid(which is white oil bolstered with full fat milk.

Organic Control and Prevention of Stink Bugs: from https://organicgardeningnewsandinfo.wordpress.com/2013/10/16/organic-control-of-stink-bugs/
1. Cultural control: Destroy heavily weeded and bushy areas in and near your garden. Adult stink bugs prefer overwintering in such sites among legumes, blackberries, Russian thistle, mustards and little mallow. Till the growing area, destroy and rid of crop debris and good weed management will help minimize stink bug populations.
2. Monitor and handpick: Stink bugs are somewhat sluggish and can be caught easily. They do release a stink gas when threatened so beware and cover your nose! Remove them and drop them into a bucket of soapy water. Shaking infested plant or tree will send them tumbling down. Vacuuming them off is also an option. Spray plants with water to knock them down and kill them off.
3. Plant trap crops: Mustard, millet, buckwheat, sorghum, sunflower, marigolds, lavender and chrysanthemums are good trap crops to attract stink bugs to attack them rather than your crop of interest. Once these trap crops are infested, the stink bugs can be killed with ease.
4. Physical traps: Yellow sticky traps or bucket painted yellow filled with soapy water can rid of quite a few unsuspecting stink bugs. An open pipe painted yellow stuck into the ground can also be used effectively for trapping stink bugs. Then there are commercially available stink bug traps that can be tried out.
5. Beneficial insects include ants, ladybird beetles and some lacewings, all of which destroy stink bug egg masses. Attract these insects by planting several nectar producing flowers.
6. Sprinkle diatomaceous earth in your garden and in prone areas. It works by breaking down the waxy protective layer on the stink bugs exoskeleton, eventually causing it to dehydrate.
7. Make a garlic spray and use as frequently as needed. Stink bugs detest the potent smell of garlic and will repel them from your garden.
8. Kaolin, a soft, white silicate clay mineral can be combined with water to form a protective physical powdery barrier that will prevent stink bugs and other pests from feeding on plant tissue.
9. Use an organic insecticidal soap and spray this solution directly on stink bugs or in areas they frequent. The soap kills the bugs by breaking down their protective exterior and dehydrating them.
10. Neem oil is another natural product that can help reduce stink bug populations by disrupting their feeding and mating habits.
11. Companion planting: Plant garlic, tansy, mint, catnip and radish to help repel stink bugs.
2. Monitor and handpick: Stink bugs are somewhat sluggish and can be caught easily. They do release a stink gas when threatened so beware and cover your nose! Remove them and drop them into a bucket of soapy water. Shaking infested plant or tree will send them tumbling down. Vacuuming them off is also an option.

I’ve been brushing them off and noticed no smell at all. I do have quite a good sense of smell, so this is odd if they are as smelly as that suggests.

Brushing them is not the same as squashing them in relation to the amount of stink. They naturally drop off plants if disturbed so a catching cloth or other materal should be laid under the plant so that fewer escape the trap.

No, the bit you quoted says when threatened. Doesn’t say anything about squashing.

Yes but they are brushed off all the time by wind. Try to pick them up and they will drop off the plant. Actually put them vbetween your fingers and they will squirt you.
I’ve cut them in half with secateurs before they knew I was there and they cannot squirt you if yu are quick enough.
How on earth could you cut something a bare 3mm across with secateurs? Some of these are barely pin head in size.

I am a watchmaker who has also spent a lot of time with my head in plants and secateurs in my hand.

Getting back to suffocating shield bugs with fatty stuff. Yes insects with exoskeletons breathe through their spiracles but coating the insect with such solutions is easier with such as aphids because one drop will attach all over the body. This does not work so easily with shield bugs as they get older. their back may get coated but it is hairless and smooth so the oil runs off. They shield their fronts with their backs. All the literature I’ve read suggests that the easiest time to attempt to control these bugs is during early instars when;
•they are less heavily protected
•they are clustered together and are able to be controlled en masse.
