Book Description
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.

Book Description
Integrated Pest Management (IPM) employs both chemical and non-chemical strategies. In both cases, foundational research is required and necessary to create an effective management tool. This dissertation explores the development of an alternative, non-chemical management tool for pear psylla (Cacopsylla pyricola) exploiting their vibrational communication. The first chapter reviews pear psylla biology and history as well as the study of vibrational communication, most recently coined as Biotremology. In the first manuscript, I characterized the mating songs of male and female pear psylla adults and assessed whether temperature and presence of conspecific individuals altered the male signal characteristics. I show that some song traits are affected by temperature while some are not. Further, that experience with the opposite sex increases the likelihood of males producing a vibrational mating song. The second manuscript explores three vibrational delivery methods to determine the efficacy of mating disruption (MD) in pear psylla employing the two MD hypotheses: competitive versus noncompetitive MD. My results showed that white noise (noncompetitive MD) was effective in reducing mating rates in pear psylla, but only when played directly to the plant substrate. Male song playback (competitive MD) was more effective than the other types of playback when going through the air using speakers. This suggests that we may be able to employ both types of mating disruption through different delivery methods. In the third manuscript, I set out to test vibrational playbacks as an enhancement to traps for monitoring and as a tool to disrupt mating in pear psylla in an orchard setting. The results showed that vibrational playback enhanced sticky card trap catch and was female-biased. Vibrational playback was more effective at reducing offspring when using white noise as vibrational playback, especially in the Anjou pear variety. The results from these experiments will contribute to the body of knowledge and tools for pear psylla IPM and as a basis for developing a similar tool for other pests that use vibrational communication.

Book Description
Pest Management Programs for Deciduous Tree Fruits and Nuts attempts to present the current status of pest management programs in orchard ecosystems. The book is a collection of papers from a symposium convened on the subject for the 1977 National Meeting of the Entomological Society of America and invitational papers on commodities not covered during the symposium. In recent years, books have appeared on "integrated pest management (IPM)"; however, most of these have concentrated on field crop IPM with an occasional chapter on fruits. No publication presently exists which brings together information on the pest management programs currently being conducted on the major nut crops, almonds, pecans and walnuts. Because it is the first treatment for almonds and walnuts, the authors of these chapters have attempted not only to present the current IPM technology but the historical data which led to the contemporary programs. Two chapters appear on pecan IPM. The first concentrates on the development of a management program for the pecan weevil, the key arthropod pest of pecans, while the second discusses the implementation of pilot pecan IPM programs in two southeastern states. The latter chapter illustrates that even with a limited data bank, the pesticide load in pecan orchards can be reduced by the adoption of the IPM approach to pest control.
