A variety of collecting methods was used, including netting, light attracting, light trapping and pheromone trapping. The specimens were identified by the currently available pictorial sources and determination keys. Many were also sent to specialists for confirmation or identification. The majority of the data was from Kanawha County, reflecting the area of more intensive sampling effort by the senior author. This imbalance of data between Kanawha County and other counties should even out with further sampling of the area. Key Words: Appalachian Mountains,

A large number of tortricid species have been inadvertently introduced into North America from Eurasia, and many have the potential to inflict considerable negative economic and ecological impacts. Because native species behave differently than introduced species, it is critical to distinguish between the two. Unfortunately, this can be a difficult task. In the past, many tortricids discovered in North America were assumed to be the same as their Eurasian counterparts, i.e., Holarctic. Using DNA sequence data, morphological characters, food plants, and historical records, we analyzed the origin of 151 species of Tortricidae present in North America. The results indicate that the number of Holarctic species has been overestimated by at least 20%. We also determined that the number of introduced tortricids in North America is unexpectedly high compared other families, with tortricids accounting for approximately 23–30% of the total number of moth and butterfly species introduced to North America.

  • Caterpillars on the Foliage of Conifers in the Northeastern United States 1 Life Cycles and Food Plants
    INTRODUCTION INTRODUCTION Coniferous forests are important features of the North American landscape. In the Northeast, balsam fir, spruces, or even pines may dominate in the more northern forests. Southward, conifers still may be prevalent, although the pines become increasingly important. In dry, sandy areas, such as Cape Cod of Massachusetts and the Pine Barrens of New Jersey, hard pines abound in forests composed of relatively small trees. Conifers are classic symbols of survival in harsh environments. Forests of conifers provide not only beautiful scenery, but also livelihood for people. Coniferous trees are a major source of lumber for the building industry. Their wood can be processed to make paper, packing material, wood chips, fence posts, and other products. Certain conifers are cultivated for landscape plants and, of course, Christmas trees. Trees of coniferous forests also supply shelter or food for many species of vertebrates, invertebrates, and even plants. Insects that call these forests home far outnumber other animals and plants. Because coniferous forests tend to be dominated by one to a few species of trees, they are especially susceptible to injury during outbreaks of insects such as the spruce budworm, Choristoneura fumiferana, the fall hemlock looper, Lambdina fiscellaria fiscellaria, or the pitch pine looper, Lambdina pellucidaria. Trees that are defoliated by insects suffer reduced growth and sometimes even death. Trees stressed by defoliation, drought, or mechanical injury, are generally more susceptible to attack by wood-boring beetles, diseases, and other organisms. These secondary pests also may kill trees. Stress or tree death can have a negative economic impact upon forest industries.
