Studies were conducted to assess glacial acetic acid (GAA) with various host plant volatiles (HPVs) and the sex pheromone, (E,E)-8, 10-dodecadien-1-ol, of codling moth, Cydia pomonella (L), as lures in traps for tortricid pests that often co-occur in tree fruits in the western United States. In addition to codling moth,...
Pear ester is a characteristic pear flavor attractive to codling moth (i.e., a kairomone). Traps baited with a pear ester lure can be used to monitor male and female adult codling moth activity. Pear ester is a natural volatile produced by ripening pears. Male and female codling moths have specialized...
Experiments were conducted in North and South America during 2012-2013 to
evaluate the use of lure combinations of sex pheromones (PH), host plant volatiles
(HPV), and food baits in traps to capture the oriental fruit moth, Grapholita molesta
(Busck) and codling moth, Cydia pomonella (L.) in pome and stone fruit...
Many factors can cause distorted growth in grapevines. One cause of distorted growth is a disorder known as Short Shoot Syndrome (SSS), which is associated with mite feeding damage. However, similar abnormal growth symptoms can be caused by spring frost damage, herbicide damage, vine imbalance (overcropping of vines), nutrient deficiency...
Premise of the study: Triassic and Jurassic fossils record structural changes in conifer seed cones through time, provide the earliest evidence for crown-group conifer clades, and further clarify sister-group relationships of modern conifer families. A new and distinct seed-cone from the Isle of Skye in western Scotland provides the oldest...

Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...
