Pistachio Extract Fights Off Bacterial & Viral Infections
With the panic of an international pandemic, citizens are flocking the grocery stores stockpiling essential food and supplies. Recent studies suggest that pistachios should be on that list of groceries to stock up on too. In addition to their known health properties, recent published research shows that pistachio extract can thwart and even kill certain bacteria and viruses. Watch this brief video with Judy Hirigoyen from American Pistachio Growers and read more about it in the coming issue of Pacific Nut Producer Magazine.

Dr. Oz Shares Why Pistachios Offer Complete Protein & Quality Sleep to Consumers
Dr Oz shared some breaking news in the health and nutrition industry at American Pistachio Growers recent Annual Conference in Monterey, CA. In addition to talking about how much he enjoys incorporating nuts in his daily diet, he shared the results of recent research suggesting that eating pistachios will not only help consumers sleep better at night, but is also one of the only plant-based foods available that offer “complete protein.” Watch this brief video with Judy Hirigoyen from American Pistachio Growers and read more about it in the coming issue of Pacific Nut Producer Magazine.

Why Oregon Hazelnut Acreage Growth has Slowed
Despite all the recent excitement in the growth of the hazelnut industry in the Pacific Northwest, the last few harvests are not quite reflecting the new acreage coming into production, and acreage growth has also slowed down this past year. Watch this brief interview with Michael McDaniel from Pacific Agricultural Survey as he shares some of the limiting factors, as well as where the growth is actually taking place.

Pollinator Partnership Equips Almond Growers with Greater Tools to Prove Sustainability
Almond growers sometimes get a bad rap in the general public as being abusive to bees or sucking too much water out of the ground, but it is quite the contrary. Almond growers are stewards of the land, and with the help of the Almond Board of California, and a new ties with the Pollinator Partnership, growers are going to be equipped with great tools to prove their environmental and sustainable practices in the orchard at bloom. Watch this brief video with the Daren Williams from the Almond Board of California for more details, and read more about it in Pacific Nut Producer Magazine.

Flower Losses Due to Shrinking Habitats and Climate Change Hurt Prime Pollinators
Without enough sugar in their diets, bumblebee queens can experience difficulty reproducing and shorter lifespans. Hollis Woodard, assistant professor of entomology at UCR, has conducted multiple studies showing how loss of plant availability negatively affects the prolific pollinators. Previous research indicates a queen’s diet can impact how quickly her brood develops, or whether she’s able to live through hibernation.
In a study published recently, Woodard and her team demonstrate that without adequate sugar, the queen’s fat body, which functions like a human liver, does not correctly produce enzymes required for healthy metabolism and detoxification from pesticides.
“The fitness consequences of not producing enough of these enzymes, P450s, could ultimately be lethal, preventing reproduction or shortening lifespans,” Woodard said. “If you don’t outright kill a queen, but she can’t lay eggs, from a population standpoint you might as well have killed her.”
Woodard’s team wanted to focus its research on bumblebee queens because they undergo an event called diapause, which is like hibernation. Queens gather an abundance of nutrients just before diapause, as it is likely one of the most vulnerable times in their lives.
A queen’s ability to survive this period is not guaranteed without adequate nutrition. However, the team also wanted to know about the sublethal effects. “We wanted to ask if other signs of distress might be detectable in advance, and whether there are molecular signs queens might not make it through diapause,” Woodard said.
The research team collected queen bumblebees of varying ages and fed them one of four diets ranging from no sugar to extremely concentrated sugar. They found queens in the oldest age group, roughly 12 days old, who were fed the most sugar, began to exhibit gene expression patterns consistent with the beginning of diapause. This suggests queens may have an internal mechanism to detect the amount of stored sugar in their bodies, Woodard said. By extension, it means there may be a way to detect in advance when queens do not have enough sugar to survive diapause, or for their fat bodies to produce enough enzymes to protect them from damaging pesticides.
This research underscores the importance of bumblebee food resources, which have been dwindling in recent years due to habitat loss. “There are studies showing gaps in floral availability late in the season before diapause, when queens most need food,” Woodard said.
In addition to habitat loss reducing bumblebees’ preferred plants, climate change may also be taking a toll. As winters become warmer, queens may emerge earlier from diapause in winter when fewer flowers are available to them. Their physiology becomes uncoupled from the seasons, making it less likely that they survive, or that their nests will be successful.
Many bumblebee species are declining, which could eventually have consequences for the human diet. Bumblebees, unlike honeybees, are native to the U.S. and perform a type of pollination essential for some of humans’ favorite foods, such as tomatoes, blueberries, potatoes and almonds.
Therefore, Woodard believes every effort must be made to ensure bumblebees, especially queens, have enough flowers to feed on. “It’s important for everyone from land managers to people with gardens to plant things bumblebees can feed on,” she said. — By Jules Bernstein, University of California, Riverside
