AbstractThe Rhyacionia frustrana group of pine-tip moths consists of at least three species: true R. frustrana (Comstock), which occurs from Central America and northern Florida north to Missouri and Massachusetts; R. sonia n. sp., present from southern Maine west to southern Manitoba; and R. bushnelli Busck, which occurs from New Mexico north to Nebraska and eastern Montana. Adults of all three species are superficially identical. A lectotype is designated to establish the identity of R. frustrana, and R. sonia is described as new to science on the basis of markedly differing genitalia. R. bushnelli, long regarded as a domestic introduction of R. frustrana, seems more likely a distinct species endemic to the western plains because of its differing overwintering habit and size.

This series of Key Plant, Key Pests publications are designed for Florida gardeners, horticulturalists and landscape professionals to help identify common pests associated with common Florida flora. This publication, the seventh in the Key Plant, Key Pests series, helps identify the most common pests found on Pinus sp. This publication provides information and general management recommendations for borers, pine sawflies, pine bark beetles, pine tip moths, fusarium rust, pine chlorosis, and pitch canker.

AbstractSynthetic sex attractants were used to trap Rhyacionia pine tip moths throughout the western United States in spring and early summer 1977 and 1978. Some species were shown to have much wider distributions than previously known. Among species responding to (E)-9-dodecenyl acetate, R. zozana was collected over most of the area, with new records for Washington, Idaho, Montana, Wyoming, and South Dakota; R. neomexicana was found for the first time in Utah, as was R. salmonicolor in New Mexico, Colorado, and Utah; R. monophylliana in Nevada and Utah; R. jenningsi in New Mexico; and R. multilineata in Arizona and Oregon. Among species caught in traps baited with (E,E)-8,10 dodecadienyl acetate, R. busckana was found widely through the Northwest, for the first time in Montana and Wyoming, and R. fumosana was captured throughout the Rocky Mountain states, with new records for Montana, Utah, and Nevada. Sets of two previously unknown zozana -like moths were collected. One is closely associated with the typical form in Oregon and California; the other is a pinyon associate in Colorado and New Mexico.

Abstract Growth impact of pine tip moths (Rhyacionia spp.) in two 12-year-old Arkansas loblolly pine (Pinus taeda L.) plantations was measured, and growth loss through rotation was projected. Two tip moth control treatments (azinphos-methyl foliar spray and carbofuran granules) were appliedto trees in the protected treatments at ages 3, 4, and 5, and growth was compared to unprotected trees at 2-year intervals. Trees in protected treatments had significantly greater average height (2.0 ft), dbh (0.35 in.), and total volume (182 ft³/ac) than did trees in the unprotectedtreatment. Volume losses at age 12 were proportional to tip moth infestation levels during the period of protection. Potential long-term impact of a tip moth was estimated using the results of this study as input to growth and yield models for thinned and unthinned stands. Projected gainsfrom early tip moth control in light to moderately infested stands were: unthinned, 2 to 6 cords/ac at age 30; thinned, 300 to 700 bf/ac of sawtimber and 1 to 3 cords/ac of pulpwood on a 35-year rotation. An economic analysis comparing the present value of growth benefits to the treatmentcosts showed tip moth control to be marginally cost effective only in the thinned, sawtimber regime. South J. Appl.

AbstractEucosma gloriola Heinrich is distinguished from E. sonomana Kearfott, a closely related species, by using differences in morphology and distribution. E. gloriola is notably smaller in alar expanse and in size of male genitalia. The distribution of E. gloriola follows closely the natural range of eastern white pine (Pinus strobus L.), while E. sonomana follows that of ponderosa pine (P. ponderosa Laws.).Eucosma gloriola overwinters in the pupal stage in the soil. Adults emerge from late April to mid-May in eastern and southern areas, and from late April to early June in northern areas. The insect passes through five larval instars within a pine shoot. Larvae emerge from shoots and drop to the ground in early July in eastern and southern areas, and somewhat later in northern areas.Symptoms of attack and injury by E. gloriola in two- and five-needle pines are distinct from those of other eastern shoot and tip moths. The destruction of leaders is the most important injury since stunted and deformed trees result from repeated attack.Large-scale chemical control methods as required in reforestation plantings of Christmas trees are difficult to achieve. Glypta sp. was the most abundant of five parasites reared from the eastern pine-shoot borer.
