Invasive wood borers vectoring pathogenic fungi have nearly exterminated several North American tree species, and it is unclear whether landscape dominant trees, such as pines, will face similar threats in the future. This paper explores the economic impacts of a hypothetical arrival of a...

A new distribution map is given for Tobacco etch virus (Potyviridae: Potyvirus). The hosts include bell pepper (Capsicum annuum), tomato (Solanum lycopersicum) and tobacco (Nicotiana tabacum). Information is provided on the geographical distribution in Europe (Cyprus, France, Hungary and Russia),...

A new distribution map is provided for Bean pod mottle virus. Comoviridae: Comovirus. Hosts: common bean (Phaseolus vulgaris) and soyabean (Glycine max). Information is given on the geographical distribution in Asia (Iran), North America (Canada, Ontario, USA, Alabama, Arkansas, Illinois, Indiana,...

Field tests were conducted during 2001 and 2002 in northeastern North Carolina to evaluate the impact of cultural practices and in-furrow insecticides on the incidence of Tomato spotted wilt virus (genus Tospovirus, family Bunyaviridae, TSWV), which is transmitted to peanut, Arachis hypogaea L.,...

Two weevils, H. pales and P. nemorensis, were studied as potential vectors of L. procerum, the causal agent of procerum root disease. Transmission of the fungus to living trees was determined by caging field-collected and artificially contaminated H. pales and P. nemorensis on eastern white pine (...

The study reported was carried out in 4 Christmas tree plantations of eastern white pine (Pinus strobus) in SW Virginia. Trees were 1-14 yr old in 1988 at the beginning of the study, when those showing symptoms of infection by Leptographium procerum were assigned to one of 4 symptom categories...

An insect survey was conducted in 10 Pinus strobus Christmas tree plantations in southwestern Virginia. Five plantations had trees showing symptoms of V. procera root disease, while 5 had asymptomatic trees. Weevils (Hylobius pales and Pissodes sp.) and bark beetles (in the genera Pityogenes,...

Field tests were carried out at various sites in New York State, Delaware, Pennsylvania, Rhode Island, Maryland, Virginia, North Carolina and Wisconsin in 1975-76 to evaluate the effectiveness of surrounding elm [Ulmus] groves with sticky traps baited with multilure [ alpha -cubebene, with...
