This book was released on 2020 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of pesticides to produce fruit crops is essential to the economic success of farmers. Consumers have a high standard for acceptable fruit, and pesticides are key to the farmer's ability to produce marketable fruit. In the past 50 years, there has been a shift towards using safer active ingredients to protect both humans and the environment. The government continues to ban unsafe, broad-use pesticides, and label new chemistries with more specific active ingredient targets. If this trend towards more responsible pesticide usage continues, there will be a need for more direct targeting of the pesticides on the crops. The most common method of pesticide application is airblast spraying. This method has huge drawbacks. It has been shown that with airblast application, less than 0.1% of pesticides applied to crops reaches its target pest. Most of the pesticide is lost to drift, leaching, and degradation by the sun, and risks exposure to non-target populations. Trunk injection should be considered as an alternative delivery method for pesticides. It delivers the pesticide directly into the tree's system without losing pesticide to drift and is contained within the tree. Trunk injection has been effectively used to control foliar pests in apple trees and wood boring pests such as the emerald ash borer. One injection can provide multiple seasons of control. In the current two studies, we use trunk injection to apply insecticides and evaluate their efficacy at controlling two very different orchard pests, the pear psylla in pear and the black stem borer in apple. The objective of the first study is to compare the efficacy of abamectin and azadirachtin in the control of pear psylla in pear using two different application methods, airblast and trunk injection. Trunk injections of abamectin and azadirachtin were compared to airblast applications of equal labeled rates on 33-year-old Bartlett Pear trees (Pyrus communis L., var "Bartlett"). The abamectin and azadirachtin trunk injected treatments controlled pear psylla as well or better than the airblast applied treatments. Trunk injecting from the first season provided a moderate level of control into the second season, one year after the injections. The objective of the second study is to evaluate the efficacy of two insecticides, emamectin benzoate and azadirachtin, and injection timing fall and spring, on their ability to control BSB in apple trees with simulated topworking and ethanol injection as an attractant.

Book excerpt: Pear psylla (Cacopsylla pyricola [Foerster] [Hemiptera: Psyllidae]) is an important pest of pear in Washington. Honeydew produced by pear psylla causes fruit russet, and serious infestations can stunt and defoliate trees. Pear psylla likely arrived in the United States along with shipments of pear nursery stock from western Europe. It was first found in Connecticut in 1832 and spread to Washington State by 1939. Within a few years it became a serious pest throughout all pear growing areas in the Pacific Northwest.

Available in PDF, EPUB and Kindle. Book excerpt: In the last few decades there has been an ever-increasing component in most BSc Zoology degree courses of cell biology, physiology and genetics, for spectacular developments have taken place in these fields. Some aspects of biotechnology are now also being included. In order to accommodate the new material, the old zoology courses were altered and the traditional two-year basis of systematics of the animal kingdom, comparative anatomy (and physiology) and evolution, was either severely trimmed or reduced and presented in an abridged form under another title. Soon after these course alterations came the swing to modular teaching in the form of a series of shorter, separate courses, some of which were optional. The entire BSc degree course took on a different appearance and several different basic themes became possible. One major result was that in the great majority of cases taxonomy and systematics were no longer taught and biology students graduated without this basic training. We field biologists did appreciate the rising interest in ecology and environ mental studies, but at the same time lamented the shortage of taxonomic skills, so that often field work was based on incorrect identifications. For years many of us with taxonomic inclinations have been bedevilled by the problem of teaching systematics to undergraduates. At a guess, maybe only 5% of students find systematics interesting. It is, however, the very basis of all studies in biology - the correct identification of the organism concerned and its relationships to others in the community.
