Zebra Mussels On the Move:
Lake Lewisville and Lake Bridgeport

Zebra mussel (Dreissena polymorpha) larvae, known as veligers, have been confirmed in Lake Bridgeport. The news comes days after the discovery of the invasive exotic in Lewisville Lake.

It is important to note that to date no settled juvenile or adult zebra mussels have been found in Lake Bridgeport to suggest a self-sustaining population.  Given the high mortality rates of zebra mussel veligers it’s not a guarantee that a population exists but given these results and the DNA results from the past two years it is likely that the lake is infested. - Read More.

Texas Parks and Wildlife, the Lady Bird Johnson Wildflower Center and other partners are working together on a campaign to stop the spread of zebra mussels by allowing visitors to REPORT SIGHTING or request free outreach material.

Proposals Sought for Pest Projects Supporting Distribution Studies & Collaboration Efforts

Proposals are now being accepted for the Cooperative Agriculture Pest Survey (CAPS) Program for calendar year 2014 surveys. The purpose of the Cooperative Agriculture Pest Survey program is to provide a distribution profile of plant pests in the United States deemed to be of regulatory significance to USDA-APHIS-PPQ, State Departments of Agriculture, tribal governments and cooperators by:

 1. Confirming the presence harmful plant pests; and
 2. Establishing and maintaining a cooperator or stakeholder network of cooperators to safeguard plant resources. 

Proposals must be submitted to Awinash Bhatkar, no later than July 25, 2012.  Please refer to the survey 2014 CAPS guidelines for details and templates.  - Read More.

Invasion of the Asian Tiger Mosquito

Aedes albopictus (Asian tiger mosquito) has been a problem in Texas for decades, and now that problem is now is expected to get worse due to warmer climate conditions.  The first U.S. sighting was in Texas in the 1980s, where it was found in a shipment of tires (which can hold the standing water provided mosquitoe breeding habitat). 

This mosquito is extremely aggressive and partly titled "tiger" because, once it attaches to skin, it does not let go.  It also transmits more than 20 diseases, according to the Cornell Chronicle, including West Nile fever, dengue fever, yellow fever and two types of encephalitis. - Learn More.

Citizen Science Workshops

Sentinel Pest Network & Invasive Species Workshops
Invaders of Texas program workshops train volunteers to become "citizen scientists" to identify, detect and report invasive plant species.  Workshops can include sessions on the Sentinel Pest Network, which serves to increase the probability of early detection of Emerald Ash Borer, Cactus Moth, Asian Longhorned Beetle, and other pests of regulatory significance.  Workshops can be tailored to meet the interests of your volunteer group, and supplementary session examples include an introduction to the TX Invaders mobile application and the Eradicator Calculator, a feature on designed to help organize and track volunteer-based eradication efforts.
