This is a badge bit (BB) that is part of the PEP curriculum.  Completing this BB is part of getting the straw badge in Animal Care.

For this BB, you will control leaf eating beetles with permaculture!



For this BB, the minimum requirements are:
 - Control leaf eating beetles with permaculture
         - colorado potato beetle
         - japanese beetle
         - other leaf eating beetles
     - Not
         - DE
         - soap sprays or any kind of spray
         - squishing
         - BT
     - Do four of these things
         - improve diversity of plants
             - some species improve the strength and health of target plant
             - diversity of plants in a polyculture to allow most plants to escape beetle attack
             - some species discourage beetles
             - Some cultivars are resistant to beetles
             - some species draw beetles away from other species (sacrifice)
                 - these species typically attract beetle predators
         - build beetle predator habitat
         - add mulch to support health of target plants
         - bring fowl in to eat the beetles
         - Trap crop (grapes?) to attract beetles then shake trellis to feed chickens below
         - Demonstrate how landscape texture and underground diversity allow some plants to thrive while others suffer from beetles
                 - Texture could be 7’ hugelkulturs
                 - Show plants within 20’ of each other, one thriving, one suffering.  

To document your completion, provide proof of the following as pics or video (less than two minutes):
     - state which four beetle control measures you will implement
     - before, during, and after construction/implementation of each of the four beetle control measures you select to implement
     - Prove your efforts mitigated beetles.    Here are two possible ways to prove it:
         - Have a “control” patch and document results during the time of year when beetles are a problem
         - Document one year without and one year with controls, same time of year

I'm dealing with my first CPB outbreak right now and while searching Permies for threads on the little buggers, I ran across this. The list of things to try is useful and maybe I'll submit for this BB next year if I find the techniques are working. I have several varieties that I grew from true seed last year and I see a big disparity in what the CPB are attacking. So my first thought for combating them was to develop a resistant landrace of potato. Can I petition to have that added to the list or something? Or maybe it's not considered a kosher approach?

Last year, several of my fruit trees experienced a cherry sawfly and leaf-curl beetle infestation. I began learning what I could do for them. I added mulch and planted tree guilds, including garlic, strawberries, and alfalfa on two plum trees. Under one tree, the alfalfa and garlic did very well, and because of this, I postulate, the leaf-curl beetle wasn't a problem at all. Under the other tree, only 10 feet away, where the alfalfa got over-weeded and not much of the garlic came up, the pest level was about the same, or worse.  I take this as proof that the plant diversity under the first tree helped it repel the beetles and flies.  So this year, I added even more permie tree candy:
a. I ran my young chickens and ducks under the trees once a week.
b. I added back the alfalfa and garlic, plus more plants, such as clover and marigolds, peppermint and calendula and green onions
c. I added more mulch.
d. I created a specific ladybug habitat and grew cilantro and parsley nearby, which I learned is beloved by lacewings and preying manti, more beetle predators.
The result?  The sick tree made it through the beetle's active season and put on new, healthy growth. I expect the beetle presence next season to be few to none.  I can't wait to show other gardeners how it can be done!

The "after pic", showing the successful, new growth of the tree, beyond beetle phase. Despite the scared, curled leaves, the healthy new growth bodes well for the tree's future
The successful regrowth of the branches, after the beetle season, shows the tree is healthy and may do well in future seasons

After all the beetle remediation work is done. I circled mulch, Peppermint plants added to the tree guild, and my ladybug house on the fence. There are little dots on the ground representing chicken love 💩
