8A —Marshall County Post, Thursday, April 25, 2024 They’re back: Brood XIX ready to invade DUANE SHERRILL Contributor B rood XIX is about to make its fi rst appear- ance since 2011 bringing ear-splitting noise and potential for plant dam- age as billions or even trillions of the cicadas will make themselves known pretty soon for just over a month before disappearing for another 13 years. Middle Tennessee ap- pears to be in the cross- hairs of this year’s emer- gence. Brood XIX is only one of the broods that impact this area. Brood XIV, for instance, will re- turn next year after last being seen in 2008, mak- ing them a 17-year cicada. According to informa- tion provided by Dr. Kar- la Addesso, Entomologist and Director of the Ten- nessee State University Nursery Research Station in McMinnville, cicadas usually emerge in early May. Their numbers can di ff er greatly in density across the emergence area. After fi ve days or longer and depending on temperature, adult cica- da activities begin, both in fl ight and song, as they gain strength in their muscles. Adult males usually produce charac- teristic sounds in chorus trees during courtship to attract females. This high-pitched, shrill call is produced by two drum- like membranes on the side of the abdomen. Adult periodical cica- das are medium-size in- sects. The body is black, while the legs, eyes and wing veins are reddish- orange. Mature nymphs are commonly found within the top few inches of soil. When soil temper- atures reach 64 degrees nymphs will begin dig- ging to the surface. Fol- lowingmating, the female cicada uses her knife-like ovipositor to deposit eggs into slits made on twigs. The female can lay 24 to 28 eggs in each slit and will repeat this pro- cedure, cutting numer- ous slits along the same branch and depositing more eggs. Each female can lay approximately 400 to 600 eggs during her lifetime, which can be four to fi ve weeks. Egg laying is the ma- jor cause of cicada dam- age in nurseries and new- ly planted orchards. Egg laying punctures causes the twig tips to wilt and leaves to turn brown; a condition referred to as “ fl agging”. Also, egg- laying wounds can serve as entry routes for other insects and diseases. After about a month, eggs hatch into wing- less white nymphs with an ant-like appearance. These nymphs fall from tree branches and dig into the moist soil using modi fi ed front legs until a suitable root is found. Cicadas have piercing- sucking mouthparts, and nymphs feed by sucking xylem sap from the roots. The nymphs continue to feed and develop for 13 or 17 years, depending on the species. In their fi nal year, the mature nymphs will emerge from the ground shortly after sunset and crawl onto a vertical surface, which is often the bark of young trees or neighboring vegetation. At this stage, they molt for the last time and metamorphose into fully-winged adults on young trees during nighttime hours between 6 p.m. and 9 p.m. Dur- ing this process, the old empty exoskeleton is left behind. Over a few hours, the wings expand fully, and the body obtains its natural pigmentation. Once the adult is fully hardened, it will fl y into a nearby tree canopy and the life cycle repeats. Egg-laying damage by female cicadas have been observed on over 200 woody tree species. Woody trees with the most noticeable symp- toms include American hop hornbeam, Ameri- can hornbeam apple, ash, cherry, cypress, dog- wood, elm, grapevines, hickory, maple, oak, peach, pear, redbud, ser- viceberry, and willow. During insurance appraisal of egg-laying damage in 2011 by Brood XIX (13-yr cycle) at seven Middle Tennessee nurs- eries, those trees deter- mined to be “Damaged Beyond Repair” includ- ed: seven species of oak, four species of maple and cherry, three species of redbud and peach/plum, and two species of elm, dogwood, and willow; single species included golden raintree, holly, honey locust, London plane tree, serviceberry, sourwood, sugarberry, and tulip poplar. Small trees can be protected by enclos- ing them in cheesecloth, tobacco canvas, mesh screenings (<1/2-inch or 3/8-inch openings, and polypropylene fabric. Ahern reported netting gave the best protection and cost less than chemi- cal control. Covering pro- tection should be applied just before emergence until adults are gone 6–8 weeks later. Pro- tect ponds in ornamen- tal plant facilities with screen or plastic mesh to avoid any buildup and decay of periodical cicadas (oxygen deple- tion of water has been observed when decaying cicadas are present); and regularly clean irrigation pond skimmers or fi lters during periodical cicada emergence to avoid any blockage. As for their numbers, Dr. Addesso said that Cicada scientists believe that emerging every 13 or 17 years in huge num- bers is their defense. It is referred to as the ‘preda- tor satiation hypothesis.’ Since the insects have no physical defenses, they overwhelm predators by emerging in such high numbers that the preda- tors can’t eat them all. That allows the survi- vors to mate and lay eggs safely after the predators in the area are full. They can be as dense as one million per acre. Dr. Addesso noted that one thing that is sometimes overlooked about the outbreak is that they often can make meals for not just ani- mals but also people. “You can think of ci- cadas as ‘land shrimp’. Eating them is safe as long as you are not aller- gic to shell fi sh,” she said. “There are a number of free recipe books online. The newly emerging ci- cadas are the best to eat because their shells have not yet hardened. To col- lect these, wait until 9 pm, grab a headlamp, fi nd a large tree and look for cicadas hanging up- side down, emerging from their nymph skins. They will be a creamy white color.” Want to Become a Host Family? W e have always celebrated diversity in the USA and one exciting way American families can do this is by hosting a foreign exchange student. Exchange students are preparing to travel to Tennessee inAugust 2024 fromall across the world, including Germany, Spain, Thailand, Mongolia, Ecuador, and Brazil. Becoming a host family for one of these exchange students starts with a willingness to host. Here’s a story from a Chapel Hill, Tennessee host family who hosted recently – “Wewere soblessed tohost aBrazilianexchange student this past winter. A piece of our hearts is now in South America, We will be traveling to see her this December. I would highly encourage hosting an exchange student. As a mom, I am constantly trying to expose my children to people that are di ff erent than us. I want to broaden their world, not narrow it.” Lisa Chapman Sara Fletcher is another Tennessee host family and is also the Regional Director of Tennessee for the organization International Experience. She is recruiting host families in Tennessee for the 2024 students. “You can host anywhere.” Sara says , “Our students are waiting for their placement assignments; we just hope to fi nd warm and welcoming families who want to share the American culture and learn their student’s culture. We will do a background check and home visit before we approve you to host. This is really an amazing chance to give back to the world – it is also such an incredible adventure your family will never forget! I hope to hear from you.” You can contact Sara at s. f l etcher@ie-usa.org or by phone 423-310-1393.
