dammit i knew i forgot something last payday,that tester from solvita,,explain more of this rotation of your method for the bettles bro,,are you saying instead of killing them ,your moving the crop in mind to another part of your farm were they benifiting the orange and olive trees,if so how,,im asking cause i done found 2 of them big ass japenese bettle asshole in my garden this year,and i dont want them,i live in snake country and digging around in them raised boxs and come face to hand with them big bastards will draw that hand back ,lmao something that big and ugly cant be good hahahah
certain plants emit specific volatile organic compounds, and these are used as signaling system for beetles. how else might a tiny insect find a mate in an acre of soil and biomass? Since many ground beetles are essential shredders of organic matter, one might argue they are a massively important component of effective nutrient recycling and soil health, see more beetles equals higher levels of natural Chtin for example.
Whilst we generally agree fungus are the top of the decomposer chain, beetles can quickly consume dead plant matter which is then excreted alongside a coach load of beneficial microbes, these go on to further process the matter in to ionic formats for our plants.
It is highly likely, you might determine a great deal about your system from understanding what plants are growing, and what are the characters of these personalities before removal.
I suspect the immigrant beetles you report are themselves coached to come to the USA via the movement of plants and produce. It is likely the plants in your garden are the bell which leads these organisms to your space.
before you embark on a mission to eradicate the beetles, diagnose every plant in your space. it might be easier to remove the signal plant than attempt to remove an ever coming chain of beetles, themselves victims of the plants perfume and the need to procreate.
it is my expressed practice to understand each and every plant, to know its properties, and ergo to understand more about its role.
Where I was having problems with larger organic matter taking longer to decay then we might like in a hot dry country, I reintroduced some of the plants i know contain the flavanols that signal certain beetles

I am convinced, the answer to our farming problems with pest insects, will be found among the various signals we are too basic to detect. this is the essence of companion planting for me :)
this is the essence of BOX!
It is only through the encouragement of a deeper engagement with all things, that we will solve the problems we are facing today and tomorrow. Limiting the use of herbicides and pesticides, and blanket approach plant removal is an obvious place to look. We are hindered by our limited biological range of senses, but we are over powered by the capacity to think and to imagine and this mitigates all earthly limits of our construction.
