Last-instar larvae of the western cherry fruit fly, Rhagoletis indifferens, were subjected to Beauveria bassiana GHA incorporated into sterile sand and non-sterile orchard soil. Mycosis in the pupal stage was observed in >20% of buried R. indifferens pupae and >80% of larvae entering sand treated with either of two B. bassiana isolates. When pre-pupal larvae burrowed into conidium-treated non-s...

The labor-intensive nature of harvest in the tree fruit industry makes it particularly sensitive to labor shortages. Technological innovation is thus critical in order to meet current demands without significantly increasing prices. This paper introduces a robotic system to help human workers during fruit harvest. A second-generation prototype is currently being built and simulation results dem...

The wireless sensor networks used in large-scale orchard must be able to run in various environments including different heights and densities of fruit trees. Moreover, as the radio channels have different propagation characteristics in different environments, it is important to study the propagation characteristics of wireless channel in orchards environments. This paper studied the propagatio...

The traceability system of navel orange can ensure the quality and safety due to the whole process control from orchard to market. Research on the whole process of navel orange is the foundation and premise of building the traceability system. Based on the analyses of whole food chain of navel orange from origin to market, HACCP is used to evaluate the risk and latent risk of the food chain of ...

The movements of meadow voles in a field popUlation were studied using radiotelemetry during fall and winter. The voles changed from a dispersed, solitary dispersion pattern during early autumn to social clusters with communal nesting during winter. This shift occurred as the daily median temperature approached freezing. Movement was inhibited and localized during winter, except under snow when...

This paper assesses the impact of Siam’s 1901 Land Title Deed Act on land markets and land use in Bangkok. Using a sample of orchard title deeds issued in the 1880s, this study investigates the incidence of land transfers and subsequent land use patterns both before and after the transition from usufruct to full private ownership rights as a result of the 1901 Act. Survival analysis shows that ...

Actual evapotranspiration is assessed via surface energy balance at an hourly rate. However, a robust estimation of daily evapotranspiration from hourly values is required. Outcomes of surface energy balance are frequently determined via measures of eddy covariance latent heat flux. Surface energy balance can be applied on images acquired at different times and spatial resolutions. In addition,...

The study was conducted at 10 – yearsold walnut orchard at Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni-Solan(H.P.) to find out the effect of integrated nutrient management on leaf nutrient status of walnut (Juglans regia L.). There were 13 different treatment combinations of organic and inorganic fertilizers. Treatments were applied on per tree basis. Among the treatments re...

We assessed the efficacy of free-ranging dogs, confined by buried fences and electronic collars, for reducing deer damage to apple trees in three commercial apple orchards in Oswego County, New York State. During 1995 and 1996, we monitored paired dog-protected and control plots in each orchard. Within dog-protected areas, the percentage of damaged buds was lower, and fruit yield was higher in ...
