Oxythyrea Funesta bites an insect that devours roses from the inside

This season I find in some of my roses enough insects like these.
I have researched and I believe they are Oxythyrea Funesta. They are insects that do a terrible job with the roses. It enters inside as soon as it begins to open the cocoons. From inside they devour the rose and when it finally opens it is totally deteriorated.
It is very difficult to remove them from the interior of the little open roses. I have tried it but in the end my own fingers damage the petals.
Has anyone had a bug like this in their roses? What treatment do they apply? Is there any effective method to fight them?
I have read somewhere that this 'shroud beetle' (that's its common name here in Spain) is more attracted to light-colored roses. But I have found that they get so much into the clear, dark, large, small, many, and few petals. In all!!!
I have read some comments in this forum about an insect that you call "Japanese beetle." Is this Japanese beetle the same insect that I show in my images?

Japanese beetles: too late to kill them off?
Comments (37)Wow! Lot's of great ideas, but most won't work...don't waste your sanity or household funding on traps and chemicals. You have to know the insect's vulnerability and have the willingness to go to town on them a few days a week when they come out to breed...usually in the month of July...the little buggers bee-line straight for anything resembling roses, vining plants and assorted fruiting trees...treating you garden like government cheese. Here's the trick. The Japanese beetle's vulnerabilty is temperature and it's innate tuck & roll defense strategy. When the sun goes down and the temperature drops the beetles do not fly. Simply put your non-dominant hand under the leaf of the plant and then lightly tap the leaf with the other and they will fall directly into your palm...they don't bite, sting or scratch...no worries. You can humanely crush them between your digits or if you're a wimp you can put them in a jar at the end of your raiding mission...cap the jar and let the sun bake them the next day...empty jar of baked beetles in the trash, rinse and repeat the following evening. I guarantee they will get the hint and you can have your garden back....See MoreJapanese beetles attack
Comments (39)They get worse every year, have been swarming but I noticed they pick certain spots on certain plants and blooms. I see by all the holes that I've missed a bunch, didn't go out for awhile. I tried the 2 inches of Dawn in a spray bottle, shook to mix it, and it worked. BUT I oversprayed a lot of places and damaged several plants, both roses and perennials. So no more of that but will try it on weeds, almost works like RU. So I had part of a bottle left of Bayer Advanced Rose and Garden Insect killer. I had four but swore I wouldn't use them any more on roses. But my cat got fleas bad and I couldn't afford much then and it has the same active ingredient in Advantage you put on the cat, just less strength. I sprayed the carpet and bad places with the Bayer and Adv on the cat, $10 a pop, vet asst told me it take four apps for the cat to mop up the fleas, she was right. Just have to get away and not let the cat near it til it dries, then it's ok although some spots I had to do 3 times. Darn cat knew where the fleas were and wouldn't walk through there and made sure to jump up on something high lol. The active ingredient is imidacloprid which kills bees. So I put on latex gloves, pruners in one hand and spray bottle in the other. Zaps them. If I spray a flower or get some on a nearby flower, I prune it right off and deadhead a little at the same time. I don't have to worry about the dormant roses they swarm on or rose leaves because bees usually only stop at blooms. I go out between 5 and 6, there are a few bees, but I haven't accidentally killed any. I like it because I can cover more territory faster, clip other stuff at the same time, aim further than I can reach, far fewer get away than they do from the soapy water drowning, and it's working better for me even though I know there are tons more up in my birch trees I can't reach. If you're still doing the soapy water, 3 swarms together won't work, but if they are swarmed in a rose blossom, I cup my hand over the blossom which keeps them from flying up, get the water underneath and tease them out of the bloom, most just drop right into the soapy water but I get petals in it and pick them out. terryjean, I don't know where you are in IL, but they must really be bad in Peoria County. I read in my Illinois Farm Bureau Farm News that the crops were showing signs of heat stress and no rain and that crop dusting planes were spraying for Japanese Beetles and also fungicide. I think with the wet spring, many farmers got their crops in late, the corn was at the silk stage, and too many beetles will get an ear with no corn. I was told the soybeans could take it. I shudder to think what they are spraying, probably something commercial grade, but it will kill all insects along with the beetles. Here they're doing all these hideous transgenic experiments with animals, saw a picture of a beagle puppy; it's white nose and light body parts glow red in the dark, for real, photo was on ABC news site, makes me sick. But if they could do something with the beetles like that where they wouldn't cross into the other insect population, I'd be all for terminating them. Sorry it's so long, spend a lot of time learning about different things. Too hot and humid this summer to enjoy much out there, then drought. Finally got some badly needed rain and now with the Bix weekend and RAGBRAI, we are having our 3rd flood of the Mississippi this year....See MoreAre the Japanese beetles about gone?
Comments (17)I have been complaining about these guys but now I am beginning to believe that I was complaining too much. I have not had hundreds at any time. Even though they were eating my roses, there were none on my Rose of Sharon or Crape Myrtle, as reported by some of my friends. Picking them off my roses is not that bad a job. I cut rose buds when I find any without disfiguring bites. I will be using something to get rid of the grubs at the right time. A friend reported that spraying them with soapy water with cayenne pepper added worked great on plants that were too tall to reach otherwise. They MUST be close to the end of their cycle by now....See MoreMythical critters we'd love to see in our rose gardens
Comments (44)Ha, Jim! Looks like you captured a photo of the elusive Grouchodeer! Beneficial to the garden because they drop cigar ash around the beds but dangerous because they don't look where they're stepping while they wiggle their eyebrows milking the audience for laughs. Just wait till his brothers start showing up - hoo boy, that's A Day at the Races. Diane, I was thinking your badgers did sound might useful at chasing away the mice (I'm fine if the coyotes finish the mice off), but the "super at digging" part sounds suspiciously fraught with danger. I can imagine a badger uprooting an established rose because some fool gopher snuck in there for protection. I imagine you don't let small dogs or cats out into the garden at night either, for fear the same fate awaits them. You have quite the Wild Life out there.
