3、One Alien Insect with OthersRusty Rhea sighs wistfully as he talks about the beauty and peace of standing amid a grove (小树林) of deep green hemlocks in Appalachia, some of them up to 160 feet ( 50 meters ) tall and more than 500 years old.“This is a very special tree,“ said Rhea, an entomologist for

4、the U.S. Forest Services Forest Health Protection program in Asheville, North Carolina. “I was brought up here, and I dont want to see another species go by the wayside.“The evergreen trees, a hallmark of southern Appalachias national parks, are Under attack by an invasive insect barely visible to t

5、he eye but potent enough to fell the giants of the eastern United States old-growth forests.Already the tiny bug from Japan, known as the hemlock woolly adelgid (HWA), has killed upward of 95 percent of the hemlocks in Virginias Shenandoah National Park. Now they are making their way through the hal

6、f-million-plus-acre (200,000-plus-hectare) Great Smoky Mountains National Park in North Carolina and Tennessee.The hemlocks shade streams, keeping water temperatures just right for brook trout (鲑鱼) and other fish. They also house birds such as the black-throated green warbler, solitary vireo, and no

7、rthern goshawk, all three of which mainly shelter in stands of hemlock trees.Because of the insects broad impact on the entire ecosystem of southern Appalachia, HWA stands to cause wider damage than the American chestnut blight (枯萎病) of the early 1900s. That fungus from Europe killed off the once do

8、minant chestnut trees from the northeast United States to the southern Appalachian Mountains.In addition, a species related to HWA, the balsam woolly adelgid, has already killed about 90 percent of the mature Fraser fir trees in the Smokies.Acting QuicklyHWA arrived in the U.S. Pacific Northwest via

9、 nursery plants from Japan in 1924. By 1951 the tiny invader had been found in Virginia. Since then the insect has spread to more than 15 U.S. states.The key to killing the HWA is to catch if early and act quickly. Its already well established in the Great Smoky Mountains, where Rhea and others are

10、trying to stem the spread of the bugs.HWA multiply quickly: All of the insects are females that reproduce asexually (无性地), laying several hundred eggs a year. When they get to the nymph, or crawler, stage, they are dormant from about June until October, after which they emerge and establish themselv

11、es on trees.Winds and birds and other animals spread the crawlers through the forest.HWA crawlers feed on the new growth of hemlocks by piercing the twigs that hold the branches, sucking the sap, and injecting toxic saliva. The needles turn from a deep green to a grayish green and eventually die, de

12、priving the tree of nutrition from photosynthesis.An infected tree usually dies within five years of initial attack: Infection is signaled by either a white, cottonlike material that appears along a trees twigs or by the “baldness“ of a trees upper branches.Plans of AttackIn the Pacific Northwest th

13、e hemlocks seem to be tolerant of the creatures feeding, and in the cold northeast, winters seem to keep them at bay. But in the warm southeast, with weather approximating that of the insects native Asian homes, they thrive.Chemical sprays-such as insecticidal soaps and horticultural oils as well as

14、 trunk or soil injections-have helped to kill some of the HWA infestations.But spraying must be repeated every six months, and injections are expensive and last only two years at most. These methods cant be used conveniently or safely in remote areas or near the streams where hemlocks grow thickly.L

15、ong term, the best way to control the pests appears to be releasing other insects that feed exclusively on HWA. Scientists have studied HWA in Japan and China and identified three such species. One of them, the Sasajiscymnus tsugae (St) beetle, was released in areas of Great Smoky Mountains National

16、 Park in 2002.Studying what controls a species in its native habitat-including climate, predators, and host resistance-provided clues about which insects to use against HWA, said Kristine Johnson. Based in Gatlinburg, Tennessee, Johnson is a supervisory forester for Great Smoky Mountains National Pa

17、rk.“Biological control is the only long-term hope to save the trees in the backcountry (穷乡僻壤),“ she said. “We have 800 square miles (2,100 square kilometers) of contiguous wilderness. We value the native forest, and its entirely worth defending.“Risky BusinessReleasing one species of non-native bug

18、to kill another could be risky business, potentially creating another type of infestation. But scientists first quarantined and studied the HWA-killer insects.They believe the St beetles are the best answer tn the HWA problem and that they wont cause side damage. This tiny black female beetle, the s

19、ize of a poppy seed, is already spreading in the Great Smoky Mountains.But the beetle and other HWA-killer insects are seasonal, so it will take several different ones operating year-round to keep HWA in check, Rhea said. He doesnt believe HWA will be completely eradicated (根除) but will instead be k

20、ept in balance by the predator insects. “Were trying to insert a balance in a system thats out of balance,“ he said.Each St beetle can lay 200 to 300 eggs, said Ernest Bernard, professor of entomology and plant pathology at the University of Tennessee in Knoxville.Bernards laboratory is one of sever

21、al that are breeding the beetles.“Each beetle eats hundreds of baby adelgids a year,“ he said. And about 120,000 of the beetles have been released in the past couple years in the Smokies, but it is still too early to measure their impact.One good sign, Bernard said, is hat some beetle larvae (幼虫) ha
