Generally speaking, the earlier you catch these problems, the better. With that in mind, you'll want to pay extra attention to your trees, which could be showing you signs that something is amiss. Read on to find out which tree symptom experts say you need to report immediately.

Invasive species pose a threat to surrounding wildlife, and as they are not native to the U.S., they can disrupt ecosystems and create much larger problems. Earlier this year, experts called for gardeners to pull out any garlic mustard, which is classified by the U.S. Department of Agriculture (USDA) as a "terrestrial invasive." This plant sprouts earlier than others around it and is then able to commandeer natural resources. It also blocks sunlight from other species and releases a chemical that kills integral underground fungi. But not all invasive species put down roots, and another kind of invader could be harming your trees.AE0FCC31AE342FD3A1346EBB1F342FCB

If you notice perfectly round holes in the bark of your hardwoods, they might be playing host to a dangerous insect—the Asian Longhorned Beetle. The USDA classifies this bug as an invasive pest, posing the greatest threat to American hardwood trees. In fact, the agency warns that it could cause more damage to national forests and backyard trees than Dutch elm disease, chestnut blight, and gypsy moths combined.

BerdasarkanCharles van Rees, PhD, conservation scientist, naturalist, and founder of the Gulo in Nature blog, this beetle has no native predators in the U.S., and domestic hardwood trees do not have any natural defenses. With no one to eat adult Asian Longhorned Beetles or their larvae, their populations easily multiply.

"As a result, our native forests, upon which both we and wildlife depend, become a smorgasbord that gets rapidly devoured," van Rees said. "The damage that their larvae do while feeding on the inner bark and heartwood of hardwood trees usually kills them."

The punctures in the bark of your trees are actually the beetles' exit holes, according to the USDA, and they will be perfectly round and pencil-sized.

"This is where the larvae emerge once they have changed into adult beetles. Piles of fine sawdust around the base of trees is a good sign that the larvae are working within," van Rees said. He added that rounded depressions, also known as "wounds," are left by adult females when they bite into the tree bark to lay eggs. This will then leak sap, which is another telltale sign that your trees are in trouble.

According to the USDA, the Asian Longhorned Beetle is a threat to elm, birch, poplar, and other varieties of hardwoods, currently affecting areas in Massachusetts, New York, and Ohio. While this beetle has not yet been detected in Western states, all U.S. states are thought to be at risk, the agency says. Entomologists believe that the larvae originally arrived in the U.S. via wood products or crates from East Asia and then grew into adults in the states.

While the most obvious signs of the beetles are the larvae in your trees, you can also recognize the beetle itself, as it is quite distinct. They are anywhere between .75 and 1.5 inches in length, and have "bullet-shaped" shiny black bodies with white spots and long striped antennae. Van Rees pointed out that the beetles are also commonly referred to as "starry sky."

Pay attention to your trees if they seem stressed, van Rees said, which you will notice if leaves start falling off or changing from a green color to yellow.

"Keep a close eye on how 'perky' and alive your trees look as the spring progresses," he noted. "This time of year, they should be getting greener and healthier looking all the time."

BerdasarkanNicholas Martin, ahli entomologi dan pendiri dan pemimpin redaksiHacks Hack Kontrol Hama, kumbang longhorned Asia tidak berbahaya bagi Anda atau hewan peliharaan Anda, tetapi pohon Anda bisa dalam bahaya yang cukup besar. Jadi, jika Anda melihat ada tanda -tanda infestasi, Van Rees merekomendasikan untuk menghubungi Badan Satwa Liar atau Sumber Daya Alam Anda, atau Kantor Layanan Inspeksi Kesehatan Hewan dan Tanaman USDA (APHIS), segera.

"Mereka benar -benar ingin tahu bahwa kumbang telah muncul di properti Anda, karena mereka dengan sangat hati -hati melacak penyebaran dan kemajuan spesies ini," kata Van Rees. "TeleponAplikasi seperti Eddmaps adalah cara mudah untuk memberi tahu mereka, tetapi jika Anda ingin saran khusus tentang apa yang harus dilakukan, yang terbaik adalah menelepon atau mengirim email ke kantor. "

Anda dapat mencapai hotline APHIS untuk kumbang Asia Longhorned di 1-866-702-9938 atauLaporkan tanda atau gejala infestasi online. Agensi juga merekomendasikan sumber kayu bakar secara lokal bila memungkinkan, dan tidak memindahkannya, karena kumbang dapat bertahan hidup tersembunyi di dalam log ini pada setiap tahap kehidupan.
