Available in PDF, EPUB and Kindle. Book excerpt: S2Leaves harvested in 1986 from clonally propagated elm hybrids ('Pioneer', 'Homestead', '970') previously fumigated in open-top chambers with ozone at 15 parts per hundred million (pphm) or with charcoal-filtered air (CFA) were evaluated for water and nitrogen content or were fed to adult elm leaf beetles (ELB), Xanthogaleruca = (Pyrrhalta) luteola (Muller), to determine host suitability for beetle fecundity and survivorship. For all three hybrids, EL9 females fed ozone-fumigated leaves laid significantly fewer eggs than females fed CFA-fumigated leaves. Fecundity of females fed '970' leaves was higher than for females fed 'Pioneer' or 'Homestead' foliage. Fumigation treatment had no significant effect on leaf nitrogen or water content. There was a significant positive linear relationship between leaf nitrogen content and beetle fecundity for all hybrids combined. In 1988, hybrid '970' was fumigated with CFA, 15, 30, or 45 pphm ozone to determine concentration effects on EL9 fecundity, leaf consumption, and survivorship. Significantly fewer eggs were laid only at the higher concentration of ozone. Mean leaf area consumed by beetles did not vary among fumigation treatments. For both years, beetle survivorship was unaffected by hybrid or ozone concentration.S3.

Book excerpt: Excerpt from Elm-Leaf Beetle in New York State This bulletin was prepared, first to bring prominently before the public the very destructive nature of this imported insect, and second to demonstrate that it can be controlled without great expense, provided intelligent direction is given to the matter. The life-history and habits of this beetle have been given some what in detail because unless they are thoroughly understood, it is very easy to adopt means that are only partially successful or futile. In order to give the bulletin a more practical value, short accounts have also been included of three other insects, which, working with the elm-leaf beetle, have aided greatly in ruining many noble elms. In the portion devoted to remedies prominence has been given to the cost of spraying per tree, the proper apparatus and the time and manner of application. It is surprising to see what mis takes some men make in dealing with insects and how they cling to methods of no value. To offset this tendency, two of the more common fallacies are mentioned and their futility shown. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
