IN THIS ISSUE:

=================================
Fall Webworm

Fall webworm lives as a group of caterpillars that spin a communal silk web. This silk nest typically encloses the end of the branch and associated leaves. The caterpillars remain in the webbing, feeding on these enclosed leaves. When the leaves inside the web are eaten, the silk webbing is expanded to include more leaves.

---------------------------------------------------------------
Turf Insecticides and Pollinators

Insecticides, particularly neonicotinoids, have been receiving some heavy hits recently about effects on honey bees and other pollinating insects. Other pollinating insects include bumblebees, sweat bees, ground bees, flower flies, bee flies, butterflies, moths, and various beetles. Last week, I attended the National Turfgrass Entomology Workshop held in South Kingston, Rhode Island where this topic came up.

---------------------------------------------------------------
Turfgrass Rust

Turf rust outbreaks are commonly seen in late summer to early fall as moderate temperatures and long evening dew periods occur. Rust diseases are most severe on slow growing turf stressed by drought, summer heat, low-fertility, shade or compaction. From a distance, severely infected turf appears thin and tinted yellow, red, or brown. Closer inspection will reveal individual blades with numerous yellow orange pustules.

---------------------------------------------------------------
New Plant Diagnostic Sample Submission App

The Plant Diagnostic Sample Submission App is a joint effort to provide a way to easily submit digital images of plant problems or pests on the go. This App is available for iOS and available for free download in the iTunes store. Farmers, homeowners, greenhouse and nursery growers, agricultural specialists and others now have a new mobile application resource to identify plants, plant diseases, insect pests and other plant problems.

---------------------------------------------------------------
Modified Growing Degree Days (Base 50°F,  March 1 through August 22)

Insect development is temperature dependent. We can use degree days to help predict insect emergence and activity.

Meet 11 Species That Are Set To Take Over The Earth


Erin McCarthy, This story was originally published by mental_floss.

Invasive species are bad news. They compete with native critters for food, destroy local ecology and, in some cases, are even dangerous to humans.

And thanks to the increasingly global nature of our world, there are more and more animals discovered where they don’t belong every year.

Here are just a few pests that have hitched rides to distant shores, where they’re currently wreaking havoc.

1.)  Cane Toad

2.)  Asian Tiger Mosquito

3.)  Burmese Python

4.)  Brown Marmorated Stink Bug

5.)  Asian Carp

6.)  Japanese Beetle

7.)  Zebra Mussel  

8.)  Red Imported Fire Ant

9.)  Northern Snakehead Fish

10.) Asian Longhorn Beetle

11.) European Starling

Invasive Species from Japan Tsunami Threaten US Shores

By Hannah Osborne: International Business Times
October 9, 2012

Invasive species, such as the Northern Pacific seastar, were washed up on US shores after the Japan tsunami.
Invasive species, such as the Northern Pacific seastar, were washed up on US shores after the Japan tsunami. More debris from the Japan tsunami has been washing up on US shores and scientists are increasingly concerned about the invasive species arriving with it.

Initially, it was thought that debris from the tsunami, which devastated Japan in 2011, would hit the west coast of the US in 2013. However, items started to wash up in April this year. In June, a floating dock drifted in to Newport, Oregon, and was found to contain 13lbs (6kg) of organisms per square foot. Most of these species originated in Japan.

Researchers at Oregon State University's Hatfield Marine Science Centre said it was difficult to assess the threat these creatures posed to the US ecosystem but as more debris arrives so too will additional species.
John Chapman, of the centre, said: "There was a huge amount of stuff. [The organisms] were very healthy, very reproductive. And included in the list of species that we could identify were some very bad characters we are afraid of having here - so yes, this really is a horrible thing."

One species found on the dock was Northern Pacific seastars. If this species becomes established in Oregon, it could cause widespread ecological and economic harm because they prey on native marine organisms. Eradication efforts are ineffective because the planktonic larvae the seastar produces are free-swimming for several weeks and can easily be transported to new locations.

Wakame kelp, known as one of the worst invasive species outside its natural environment, was also present on the dock. The Hatfield Marine Science Centre said: "This non-native golden-brown seaweed from Asia has the potential to become established along the coast where it may spread quickly and become a fouling nuisance on docks, ship hulls, nets, fishing gear, moorings, ropes and other marine structures.

"In sheltered waters, the Wakame kelp can quickly form large beds that block out sunlight essential for the survival of native kelps, seaweeds, and other marine algae."

It has been estimated that 1.5 million tonnes of debris is floating through the North Pacific Ocean.
British Columbia is preparing for an increase in debris washing ashore as it prepares for winter storms to hit the coast. While more invasive species may arrive, Jessica Miller, an Oregon State University marine ecologist, said the arrival of the dock was a sobering reminder of the natural disaster.

She said: "We have to remember that this dock, and the organisms that arrived on it, are here as a result of a great human tragedy. We respect that and have profound sympathy for those who have suffered, and are still suffering."

The tsunami hit the eastern coast of Japan in March 2011. It killed almost 16,000 people.

Study tracks release of invasive species by science teachers

About a quarter of educators said they put plants and animals into the environment once the lesson is over

Published: August 10, 2012 12:00AM, Midnight, Aug. 10 

Science teachers who want their students to get up close and personal with the natural world may be unwittingly unleashing invasive species into the environment once class is over.

A recent survey conducted by Oregon State University researchers found that many science teachers who buy organisms from biological suppliers to use in the classroom release the critters rather than kill them when the science lesson is done.

About a quarter of teachers reported releasing live organisms, and 8 percent of those organisms were known to be invasive, so researchers estimate that just 2 percent of the releases are potentially invasive.

“But that adds up, school by school, year after year,” said Sam Chan, the OSU researcher who presented the study in Portland this week at the national meeting of the Ecological Society of America.

The problem also extends to teachers who keep fish, snakes, turtles and other animals as pets in the classroom to help students learn responsibility, he said.

OSU Sea Grant researchers surveyed nearly 2,000 teachers in Florida, New York, Indiana, Illinois, Oregon, Washington, California, Connecticut, British Columbia and Ontario. They also interviewed curriculum specialists and biological supply company owners and managers.

Chan, former chairman of the Oregon Invasive Species Council, said he began looking at the issue following a parent-teacher conference where he saw a notice of a “spring release party” planned for the crawfish that the students had been studying.

The crawfish in question is the “rusty crawfish,” native to the Ohio river basin and so invasive that its importation to Oregon has been outlawed.

Rusty crawfish displace native crawfish, reduce aquatic plant populations, and also can put a dent in the density and variety of invertebrates and even some fish populations, say researchers who have observed their spread through Minnesota, Michigan, Illinois and Wisconsin.

To see them released by a school gave Chan pause.

100 of the World's Worst Alien Invasive Species


Welcome to "One Hundred of the World�s Worst Invasive Alien Species", funded by La Fondation TOTAL, and part of the Global Invasive Species Database. Invasive species have been recognised globally as a major threat to biodiversity (the collected wealth of the world�s species of plants, animals and other organisms) as well as to agriculture and other human interests.
*
It is very difficult to identify 100 invasive species from around the world that really are "worse" than any others. Species and their interactions with ecosystems are very complex. Some species may have invaded only a restricted region, but have a high probability of expanding and causing further great damage (e.g. see Boiga irregularis: the brown tree snake). Other species may already be globally widespread, and causing cumulative but less visible damage. Many biological families or genera contain large numbers of invasive species, often with similar impacts.
*
* Species were selected for the list according to two criteria: their serious impact on biological diversity and/or human activities, and their illustration of important issues surrounding biological invasion. To ensure the inclusion of a wide variety of examples, only one species from each genus was selected. Absence from the list does not imply that a species poses a lesser threat.
