Global Demand for California Almonds Remains Strong
Demand for California Almonds remains strong. Shipments for the month of November exceeded prior year by nearly 8%. Year-to-date, shipments continue to run ahead of last year at 7.4%.
Commitments for November rose by 149 million lbs., putting the 2013 California almond supply at 57% shipped and committed. The most recent estimates peg the 2013 California almond crop between 1.95 and 2.00 billion pounds.
Market demand in the US continues to be robust as shipments for November rose 8% over prior year and stand at 8.7% over prior year on a year-to-date basis.
Two of the largest export markets, China and India, showed declines against prior year of 48% and 31% respectively. Year-to-date, China sits at 16% behind last year while India is 22% behind last year.
Partly driven by a small Spanish crop, shipments to Europe were up 59% for November against prior year. Total yearly shipments are up 33.9 million pounds, 20% over prior year.
Exports to the Middle East have begun to show consistent signs of growth with November totals exceeding prior year by 88%. The region is up 20.8 million pounds, 41.6%. Growth is well distributed across the Middle East countries.
With demand for California Almonds firmly in place, prices are expected to remain solid as we progress into the bloom.

Researchers Develop System for Assessing How
Effective Species Are at Pollinating Crops
From tomatoes to pumpkins, most fruit and vegetable crops rely on pollination by bees and other insect species – and the future of many of those species is uncertain. Now researchers from North Carolina State University are proposing a set of guidelines for assessing the performance of pollinator species in order to determine which species are most important and should be prioritized for protection.

“Widespread concerns over the fate of honey bees and other pollinators have led to increased efforts to understand which species are the most effective pollinators, since this has huge ramifications for the agriculture industry,” says Dr. Hannah Burrack, an associate professor of entomology at NC State and co-author of a paper on the new guidelines and related research. “However, various research efforts have taken a wide variety of approaches, making it difficult to compare results in a meaningful way.
“We’ve developed a set of metrics that we think offers a comprehensive overview of pollination efficiency, which would allow researchers to compare data from different crops and regions.”
The new comprehensive approach looks at four specific metrics. First is single-visit efficiency, which measures the number of seeds produced when one bee visits one flower. Second is abundance, which measures the number of each type of bee observed in a study area. Third is inclement weather behavior, which tracks how active a bee species is during cool, cloudy and/or windy weather. Fourth is visitation rate, or the number of flowers that a bee visits while foraging, and the amount of time it spends at each flower.
“The perfect bee would produce a lot of seeds and visit a lot of flowers, even in poor weather – and there would be a lot of them,” Burrack says. “But as far as we know, the perfect bee doesn’t exist.”
The researchers conducted a pilot study using their comprehensive approach to assess the pollination performance of various bee species on economically important highbush blueberry crops in North Carolina. They found that small native bees had extremely high single-visit efficiency rates and were active during inclement weather. However, small native bees did not have high abundance nor appear to have high visitation rates.
“This highlights the importance of incorporating multiple metrics,” says Dr. David Tarpy, an associate professor of entomology at NC State and co-author of the paper. “Because researchers looking only at visitation rates or abundance may think the small native species are unimportant, when they actually appear to be important pollinators for blueberry growers.”
The paper, “Multiple Criteria for Evaluating Pollinator Performance in Highbush Blueberry (Ericales: Ericaceae) Agroecosystems,” was published online Nov. 25 in the journal Environmental Entomology. Lead author of the paper is Shelley Rogers, a former graduate student at NC State. The work was supported by the National Science Foundation, the N.C. Blueberry Council and the NC State Beekeepers Association.
