Keepitlow, I'm not sure they're increasing on a global scale, it's just that societies are much more mobile now, and bring pests along with them, so that there is a larger diversity of pests here. A couple more imported pests that come to mind are Japanese beetles introduced in the early 1900s, and the very recently introduced spotted wing drosophila fly. Once introduced, it has generally taken a long time for some of these pests to become omnipresent. Codling moth, even though introduced with the first settlers, didn't find it's way to Kansas until 1850. Japanese beetles, even though introduced 90 years ago, are still not found in all KS counties today. However, in the future with our society even more mobile, it may take less time for these newly introduced pests to fully disseminate. OFM has become more of a problem due to mutation. Originally it was exclusively a stone fruit pest. In recent years it has become a pest in commercial apple orchards as well. I've also read it can be a problem in some home orchards where there are lots of stone fruit and apples planted together. To the naked eye, the larva are indistinguishable from CM. Lastly, introduced pests are not limited to fruit. Bedbugs have been practically unheard of here for half a century. Remember the old adage, "sleep tight and don't let the bedbugs bite"? That came from a time when people slept on hanging rope beds. Bedbugs could be somewhat thwarted by tightening up the ropes to prevent the bed from touching the floor. In recent times some hotels (even nice ones) have had problems with bedbugs being reintroduced from overseas travelers. That'd be a case where I'm going to kill some nature, and feel really good about it.

See the black/purple chiles closest to the sun and with the least leaf cover? Common with chiles.....

Just a natural reaction to the sun -Not sun burn-will disappear as the pods color up.

Irises do not change color - not on a permanent basis, anyway. It is possible that herbicide drift can cause temporary changes in iris pigmentation (do you use RoundUp or have a nearby neighbor who does?). If that is what happened to your irises, they will probably return to normal color next year, assuming they are not subjected to herbicide again. I don't believe there are any nutritional factors that can completely change an iris's color pigment, though growing conditions can certainly influence color saturation. It wouldn't hurt to have your soil analyzed for any possible nutrient deficiencies. The amount of available sunlight and ambient temperature can also influence color intensity to some degree, though not to the point of turning one color into an entirely different one i.e. purple irises turning white. There are, however, other possible explanations for these apparent flower color changes: Irises often do not bloom every year. It is possible that your dark colored irises neglected to bloom this year, while lighter ones (perhaps left by a previous owner) within the same planting area did bloom. If you dug your original irises from a bed where only purple irises were blooming, perhaps you assumed that you dug only purple irises. However, there may have been a number of other colors of irises in the original bed that weren't blooming at the time you dug but that did bloom later in your own garden. If you dug and replanted a bed within the last several years, it's possible a tiny piece or pieces of a previous iris planting remained in the bed and has now matured to blooming size. An animal or child may have uprooted a rhizome from elsewhere and dropped it into your garden without your knowledge, or a neighbor may have tossed unwanted rhizomes over the fence into your yard where they took root. It happens. Certain cultivars are far more vigorous growers than others, and in closely planted beds, the more vigorous growers will almost inevitably choke out the less aggressive irises over time. Your original irises may have been bee-pollinated within the last few years. The seeds from those crosses may have ripened, dropped, and germinated among the original plants, and now you have a bunch of new seedlings blooming within your original clumps. Iris seed does not grow true to the parent plant and may well have produced some new colors in your iris bed. On extremely rare occasions an iris may "sport", meaning the iris may produce an offset that differs noticeably in appearance from the original plant. HONORABILE is one well-known example of a cultivar that has produced several sports in its long history. The sport offsets, however, do not change the color or appearance of the original plant. The only way to get all of this sorted out is to place a tag around each bloomstalk to identify its color, then dig and divide all of the rhizomes 6-8 weeks after bloom, replanting each color separately about 2' apart so they won't crowd each other too soon. Remove any seed pods that may form before they have a chance to ripen to avoid a repeat of this problem in your garden.
