MISSION VIEJO, Calif. - Bird-B-Gone announced its latest addition to the Bird Jolt Flat Track line of electric bird elements, Clear Track. Effective for both small and large pest birds, the Bird Jolt Flat Track System does not harm birds, but instead conditions them to avoid the area, Bird-B-Gone reports.
The system is the only electric track bird deterrent system with multi-patented anti-arcing glue trough designs, the firm said. Birds often choose to roost and nest in signs, building features, eaves and many other high-profile locations, creating health risks and causing property damage.
The Clear Track Bird Jolt Flat Track system provides an aesthetically pleasing solution to bird control problems, Bird-B-Gone said. It is flexible and can be used in any area, flat or curved.

CNN reports that Florida is bracing for an invasion of gallinippers, a mosquito that can be 20 times the size of typical mosquitoes. They are expected to invade Florida this summer.
Why do birds, monkeys and other animals rub themselves with citrus and creatures like millipedes? One likely reason is because certain plants and arthropods contain natural repellents.
Scientists with the U.S. Department of Agriculture (USDA) and the Smithsonian Conservation Biology Institute (SCBI) at the National Zoological Park in Front Royal, Va., examined citrus compounds and millipedes for effectiveness against ticks. John Carroll, an entomologist with the Agricultural Research Service (ARS) at the Henry A. Wallace Beltsville Agricultural Research Center (BARC) in Beltsville, Md., and SCBI researcher Paul Weldon tested the responses of ticks to more than 20 different compounds in citrus extracts. ARS is the chief intramural scientific research agency of USDA.
Ticks were allowed to climb on vertical paper strips containing lemon rind exudates and other citrus chemicals. Repellency evaluation was based on whether ticks crawled into treated areas, continued to move, turned around, crawled back down or fell. Experiments also involved putting ticks inside treated filter-paper packets. After one hour, the ticks were removed, placed on their backs and timed to see if and when they could right themselves and climb out of a low enclosure and onto a fingertip.
Carroll, who works in BARC's Invasive Insect Biocontrol and Behavior Laboratory, found that some ticks were unable to crawl out of enclosures or even right themselves. Of 24 ticks exposed to one citrus chemical, only one righted itself. Of the chemicals tested, one killed or disabled ticks exposed to it for an hour. Several other chemicals kept ticks from climbing onto a fingertip.
To get to the bottom of why some animals anoint themselves with crushed millipedes, scientists used similar techniques to test ticks' responses to three benzoquinone chemicals found in millipedes. One benzoquinone chemical killed ticks, one repelled them and all three benzoquinones hampered efforts of ticks to right themselves and climb. Higher concentrations of these chemicals were able to impair ticks' ability to climb for several months.

Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in St. Louis have shown.
The finding is an important step toward developing a vaginal gel that may prevent the spread of HIV, the virus that causes AIDS.
“Our hope is that in places where HIV is running rampant, people could use this gel as a preventive measure to stop the initial infection,” says Joshua L. Hood, MD, PhD, a research instructor in medicine.
The study appears in the current issue of Antiviral Therapy.
Bee venom contains a potent toxin called melittin that can poke holes in the protective envelope that surrounds HIV, and other viruses. Large amounts of free melittin can cause a lot of damage. Indeed, in addition to anti-viral therapy, the paper’s senior author, Samuel A. Wickline, MD, the J. Russell Hornsby Professor of Biomedical Sciences, has shown melittin-loaded nanoparticles to be effective in killing tumor cells.
