HELP My Adenium obesum's have bugs on them!

Can anyone ID these bugs for me and the correct poison for them and adenium obesum plants? IU have almost 60 to worry about and i don't want to hurt them.

Thanks

Aphids!

They are just aphids. I would go get some ladybugs as they are a natural predator that will devour these little plant juice sucking pests.



For aphid control: 1600 X-Clude,Diatomaceous Earth, Garden Dust Insecticide/Fungicide, Ladybug Lures, Insect Soap, Orange Guard, Rotenone/Pyrethrum Spray, Yellow Sticky Traps



Ants "farm" aphids often keeping them in their nest during winter, then bringing them out in spring and placing them on the host plant. The ants eat the honeydew the aphids produce and move them from plant to plant spreading any diseases that are present. The honeydew favors formation of a black fungus known as "sooty mold." Control of the ants may often solve the aphid problem. Aphids abound in warm moist environments and will attack almost anything, favoring succulent new growth.


Predators: Green lacewings, ladybugs and their respective larvae have a voracious appetite for aphids. Larvae from the syrphid fly also consume aphids. Hover flies and praying mantis feed on aphids.
Repellent plants: Anise, chives, coriander (cilantro), garlic, onions, petunias and radish. Nasturtiums act as a trap crop. Aphids definitely prefer yellow flowers.



  • Squashing a few aphids around the infested plants releases a chemical signal that makes the other aphids drop from the plants and leave.
  • To foil aphids: flatten a square of aluminum foil around the base of plants to bounce light on the undersides of leaves. This also helps the plants in giving them more light.
  • Try a barrier of powdered charcoal, calcium dust or bonemeal to keep them away from your plants.
  • Stinging Nettle Spray: Aphids & Thrips - Cover 1 quart nettles with water, cover and ferment for 3 weeks. Mix 1 part nettle tea with 7 parts water. Spray.
  • Spread out a barrier of tansy around the base of the plant to stop those ants.
  • Use a spray made from a tea of tomato or potato leaves and water.
  • Chop 12 or so tomato leaves and 1 chopped onion in 1/2 cup of of 70% isopropyl alcohol for a few minutes. Apply the mixture directly on aphids with a cue tip or paintbrush.
  • A forceful spray of water is often enough to knock the aphids off the plant and may discourage the ants, well sometimes.
  • Put a bright yellow plastic pan in a strategic spot in the garden. Fill it a third of the way full with water. Aphids are drawn to the yellow color, land on the water, sink and drown.
  • A soap spray can be used to strip them of their protective wax coating, dehydrating them. Mix 1 tablespoon of Castile soap to 1 gallon of water, spray.
  • Garlic oil spray can kill aphids and other soft bodied pests.
  • A dusting of diatomaceous earth is lethal to aphids. Wear a mask when using DE.
  • Teas made from elderberry or rhubarb leaves can act as a deterrent. Oxalic acid is the compound present in these plants that makes a spray effective. It is poisonous.
  • Place banana peels at the base of infested plant. The peels give them a shot of potassium too!
  • Also See: Treatments: Horseradish, elderberry and yarrow tea.
  • For wooly aphids on apple trees: grow the trailing type nasturtiums training them to wrap up and around the tree trunk to ward off these pests. Very attractive too! Note: nasturtiums will specifically attract the black aphid while repelling others.

Whoa stray! that has to be the best response Ive ever seen in a forum.
Thank you so much for the enormous ammount of information on them. I am facinated with the lady bugs being natural predators, and I will endeavour to locate some commercially. The green ants we have seem to be eating them, although very slowly.

Again thank you for an excellent reply.

Happy Growing

In the meantime, you can just wash them off with a hose, supporting the leaves with your fingers (so that the jet doesn't break them).

Thumbs up

Attila,
Yes, I should have stressed more removing them mechanically first.

Taipan,
Thanks for the nice words, but I only recognized the aphids and did a google search with keywords: aphids natural control, clicked the first link and then a cut and paste and presto! I figured the links to their products would give that site their credit due.

Does the water in Australia really go down drains anti-clockwise or is this just an urban myth?

Thanks Stray and Attila, I have hosed them all off and the stress has left my body...As to your urban myth question? Yes the water does indeed go down anti-clockwise in the southern hemisphere...As it is supposed to!

Freaks me out when i travel to the northern hemisphere to see it go down the drain the wrong way...You guys should really get some scientists and fix that problem you have up there lol
Something to do with magnetic poles i think? I too saw the simpons episode when Bart rang a kid in the outback lol...You had to love the pollitician floating in his dam lmao...very close to real life i assure you.

Thanks again for the advice guys.

Happy growing
Tai
