Pollinators Threatened by Invasive Plants

"Invasive non-native plants have been found to reduce pollinator abundance and diversity, and disrupt pollinator services to some native plants, which could reduce seed production. Although our knowledge is still limited on the effects of invasive plants on pollinator abundance and diversity, and pollination of native plants, several studies have been conducted that answer some of those questions. Results of these studies will further our understanding of the influence of plant-pollinator interactions on native plant communities threatened by invasive plants." article by 
in TechLine, Invasive Plant News. The article contained summaries of several studies on this topic.

Whole Foods is selling invasive lionfish in Florida

Whole Foods is now selling invasive lionfish at its Florida locations.

From USA Today: Since lionfish were first spotted in Florida in the mid-1980s, they have continued to spread rapidly. Florida’s Wildlife Commission estimates there are millions of the fish, which have no predators, and have wreaked havoc on native fish and shrimp populations.
Florida officials have pushed for people to combat the species in the kitchen by catching the fish and eating it.
Whole Foods is simplifying the process for Floridians who aren't into diving for their fish.
The chain began selling lionfish for $8.99 a pound on Wednesday and plan to raise the price to $9.99 a pound June 1.

Rampaging Radioactive Wild Boars Causing Havoc

by Lynne Hayes.  Original article in: Growing America. Friday April 8th, 2016

 Lynne Hayes’ article highlights a major invasive species problem being manifested in the Fukushima region of Japan, an area in Japan that includes the 12 mile radius of the “exclusion zone” that experienced the nuclear disaster resulting from the Fukushima Hamadōri earthquake and subsequent tsunami on 11 March 2011.  

As if a nuclear disaster wasn't overwhelming enough in the Fukushima region of Japan, now the farmers who live in the area are being overrun by wild boars—thousands of them—with razor sharp tusks. And to top it off, they’re radioactive.

They’re full of radiation, so not only can’t they be eaten, they must be buried in concrete pits much like any disposed of radioactive material.  That has created an even bigger problem in Japan—mass graves that were built to hold 600 boars each are already full and there is a shortage of people qualified to cremate them.

Their problem????  Not so fast: see the section: Pigging Out In America … feral hogs are OUR problem as well.  Though not radioactive, according to the USDA, the United States is home to more than 5 million feral hogs. These ‘cousins” of the wild boar are capable of devastating damage to crops and can seriously upset the balance of our ecosystem.

Map Callery Pear Challenge!

How many states are seeing Callery Pear becoming an invasive issue? Map infestations you see and let's find out! 
The University of Illinois is mapping Callery Pear in their state - Let's all join the challenge
The University of Illinois Extension Forestry is encouraging everyone in the state to map Callery Pear.  This invasive is rapidly spreading across the state.  Currently we have documented escaped populations in 65/102 counties in Illinois but we are sure it is more widespread than that.  And, based upon the data in www.eddmaps.org, we are ahead of the other states in mapping this species!  As we are asking everyone in Illinois to help fill out our map, I want to challenge the other Midwestern states to do the same!  Let’s build a single map that relays the true distribution of this species across the Midwest!
 We’re asking everyone to report to www.eddmaps.org or use the GLEDN app - http://apps.bugwood.org/apps/gledn/

Trees in Trouble: A documentary film about America’s Urban Forests. Coming to PBS

Trees in Trouble: A documentary film about America’s Urban Forests. Coming to PBS broadcasting near you in association with Earth Day/ Arbor Day programming during the month of April. The film will be aired numerous times during the week of April 25th.
Trees in Trouble http://www.treesintrouble.com/#about-film tells the story of Cincinnati’s response to the threat to its trees posed by the emerald ash borer. However, the film’s message is not limited to southern Ohio: across the country, from Massachusetts to San Diego, Minneapolis to Charleston, thousands of communities face the same threat: valuable and beloved trees being killed by non-native insects or diseases. While the trees and killers differ, the cost to the communities is the same: destruction of trees that provide shade and other important ecosystem services and create our sense of home. Trees in Trouble helps us understand what we are losing and links us to actions we can take to counter this tragedy.”   Faith Campbell, Vice President, Center for Invasive Species Prevention

 Check the PBS schedule chart at: http://www.treesintrouble.com/national-public-television-release/ to find out when Trees in Trouble will be airing on PBS in your area

Native Predators May Be Having a Larger Impact than Expected on Invasive Stink Bug

Entomology Today. March 25, 2016 issue. 
By Dr. Rob Morrison, USDA-ARS Appalachian Fruit Research Station in Kearneysville, WV. 

Research recently appearing in the journal Biological Control may change how we view native predators of the brown marmorated stink bug (BMSB). BMSB is an invasive species that was accidentally introduced to the United States from Asia in Pennsylvania, and has since been detected in more than 40 U.S. states. It feeds on more than 150 plant species, making it a large threat to many agricultural systems in the country.

Researchers with the USDA-ARS Appalachian Fruit Research Station and Shepherd University evaluated 25 native generalist natural enemy species collected from the field as potential predators of BMSB egg masses in the laboratory. 

To better evaluate and characterize damage inflicted by the various predators, the researchers photographed egg masses before and after predator exposure with the aim of linking egg damage to specific groups or guilds of predators.

Predators were also observed using videography, and some interesting behaviors emerged.  Bottom line, results suggest that native predators may not be getting as much credit as they deserve in the biological control of BMSB.
