Precision horticulture: application on apple orchards
… horticulture and spatial analysis applied to orchards are a growing and evolving part of precision agriculture technology. The aim of this discipline is to reduce production costs by monitoring and analysing orchard-derived information to improve crop performance in an environmentally sound …

Water use of mature pecan orchards under semi-arid conditions
… current data used for water management of pecan orchards are primarily based on research done in other countries or by using an empirical model to estimate water use. As different regions are characterized by its own unique climate and management practices, modeling approaches were developed that …

GENETIC EFFICIENCY IN TWO LOBLOLLY PINE (PINUS TAEDA L) SEED ORCHARDS
<p>The degree to which seed crops in seed orchards reflect the genetic variability and superiority present among orchard parents (genetic efficiency) was examined in two loblolly pine seed orchards using seven allozyme loci as genetic markers.</p><p>The frequency of outcrossed progeny in the seed …

Activity and diet of bats in apple orchards of southern Michigan
<p>I studied activity and diet of bats in apple orchards in southern Michigan. There was no difference between organic and conventional orchards in number and composition of insects captured with light traps, number of bats captured with mist nets, or number of acoustic files of bat activity that …

Leptothrips mali (Fitch): a potentially important predator in Virginia apple orchards
… Dysaphis plantaginea spp.) in Virginia apple orchards and predators (Leptothrips mali, Haplothrips subtilissimus, Orius insidiosus, Stethorus punctum, Dereacoris nebulosus, Chrysopa spp.) were monitored during 1977-78 under 3 reduced pesticide programs. The pesticide program with phosalone and …

Apple orchards feed and contaminate bees during, but even more so after bloom
… have examined the reciprocal relationship of the orchards on honey bees, particularly across the entire foraging season. Here we investigated the foraging dynamics of honey bees in an orchard crop environment in Northern Virginia, United States. We decoded, mapped, and analyzed 3,710 waggle …

Bioenergetics and nutrition of the pine vole (microtus pinetorum) in two Virginia apple orchards
Bioenergetic measurements were made on adult, lactating females, and growing juvenile pine voles. Adult pine voles showed a seasonal cycle in daily maintenance energy requirements. Winter was energetically the most expensive season. Requirements during the summer season were the lowest of all …

The influence of an umbelliferous understory on the parasites of organic apple orchards in Canterbury
… ground cover on the parasites of organic apple orchards was examined. The indirect influences on the major pest species, codling moth (Cydia pomonella L.) and lightbrown apple moth (Epiphyas postvittana (Walker)) were also investigated. Sampling was carried out in the Lincoln University …

Bionomics of Platynota flavedana Clemens and P. idaeusalis (Walker)(Lepidoptera: Tortricidae) in Virginia apple orchards
The effects of pheromone trap placement on male moth catches of both species were studied. For P. flavedana, traps hung at 2.1 and 3.0 meters captured the greatest number of moths. Trap heights of 1.2, 2.1, and 3.0 meters caught the greatest number of P. idaeusalis moths. The outside-the-canopy …

Impact of Low-Spray Mating Disruption Programs on Aphidophagous Insect Populations in Virginia Apple Orchards
… programs were surveyed in Virginia apple orchards. Two sampling methods were utilized;aphid colony collection and beating tray collection. The low-spray blocks employed the use of mating disruption for control of the key direct pests, codling moth, Cydia pomonella (Linnaeus), and …
