In arid to semi-arid regions, vulnerability climate change combined with the overexploitation of water resources is jeopardizing food security. Souss-Massa region in central Morocco, rural population relies on growing olives for a living. The management these orchards mostly traditional under rainfed irrigation, which induces high level dependence variability. present study, we investigate long...

The Guthion-resistant strain of walnut aphid parasite, Trioxys pallidus, was reared in the greenhouse on potted walnut trees and released into a commercialwalnut block near Gridley during the 1989 growing season where it established, survived Guthion,and spread to an adjacent blocktreated with Lorsban. Aphidand parasite counts suggest the parasites controlled the aphids in both the Guthionand L...

Streptomycin is used in arboriculture to control fire blight. Using sheep as a model, multidrug-resistant bacteria in mammals were found to be selected after the intentional release of streptomycin into the environment. Escherichia coli and Staphylococcus spp. were isolated from the faeces and nasal cavities, respectively, of sheep grazing on a field sprayed with streptomycin at concentrations ...

In the present study, 3 replanted black pepper orchards with continuously cropping histories for 10, 21, and 55 years in tropical China, were selected for investigating the effect of monoculture on soil physiochemical properties, enzyme activities, bacterial abundance, and bacterial community structures. Results showed long-term continuous cropping led to a significant decline in soil pH, organ...

during an investigation on edaphic mite fauna of orchards and parks of tehran, some species belonging to the superfamily pygmephoroidea were collected and identified, of which bakerdania graciloides sevastianov is considered to be a new record for iran.

We developed new integrated pest management programs for eastern U.S. peaches with minimal use of organophosphates. From 2002-2005, we assessed the ecological impacts of these reduced-risk programs versus grower standard conventional programs that still relied primarily on the use of organophosphorous and carbamate insecticides. Using a split-plot design replicated at four commercial Pennsylvan...

Low dietary intake of Ca in humans has been epidemiologically linked to various diseases, which can have serious health consequences over time. Accordingly, the development an agronomic itinerary for biofortification Rocha pears and assessment physicochemical deviations prompted this study. Two orchards with contrasting soil water characteristics were selected, characterized through orthophotom...

Thrips were sampled from six nectarine orchards in the Dry Central Interior, British Columbia, Canada, between April and June 1993 using yellow sticky cards on posts spaced around the perimeter of each orchard. Although 12 identified species of thrips were captured, >90% of individuals were the western flower thrips, Frankliniella occidentalis (Pergande). The flight patterns and abundances of w...

Abstract Studies were conducted in apple, Malus domestica Borkhausen and pear, Pyrus communis L. (Rosales: Rosaceae), orchards to evaluate the attractiveness of grey halobutyl septa loaded with 1 (L2) and 10 (Mega) mg of codlemone, 8E, 10E-dodecadien-1-ol, 3 mg of pear ester, ethyl (E,Z)-2,4-decadienoate (DA2313), and 3 mg of pear ester plus 3 mg of codlemone (Combo) to adult codling moth, Cydi...
