Six-legged soldiers

Insects have been converted into weapons of war and tools of terror for millennia. A new book asks: Are we ready for the next wave?

By | October 24, 2008

Adapted from the epilogue of linkurl:__Six-Legged Soldiers: Using Insects as Weapons of War__:; __Dusk descends on a sweltering linkurl:New Orleans.; A naked man lies moaning in an apartment a few blocks from Canal Street. His jaundiced body is mottled with bruises where vessels have hemorrhaged. The pillow and bedside are caked with blood that he has vomited. The man's breathing is labored as he drowns in his own fluids. The window of the room is shut tightly, letting in no breath of air - and letting out none of the thousands of mosquitoes that cover the walls and the man's body. linkurl:__Aedes aegypti__; is not the most common species along the Gulf Coast, but anyone with a course in linkurl:medical entomology; could build a simple trap and conscript a bloodthirsty army. Across the hall, another man cracks his door and peers out. Seeing nobody in the hallway, he emerges wearing linkurl:beekeepers'; garb. After slipping into the sickroom, he watches as a convulsion wracks the martyr's body. The insects rise in a ravenous cloud, droning their annoyance at having their meal disturbed. Taking advantage of the moment, the garbed man crosses the room and opens the window...__
__Insect-borne diseases were rampant in Civil War hospitals such as this one in Washington D.C. (Library of Congress)__
Using insects as weapons of terrorism seems darkly fantastical but the history of entomological warfare suggests that such a scenario is frighteningly plausible. linkurl:Jack Woodall,; director of the Nucleus for the Investigation of Emerging Infections Diseases at the Federal University of Rio de Janeiro, warns that years of complacency and a focus on disease darlings linkurl:(bird flu; being a recent media favorite) have set up the American public for an outbreak - natural or otherwise - of linkurl:yellow fever.; The potential for this disease to decimate a civilian population was understood by American linkurl:military; strategists in the 1960s. linkurl:Biological warfare; researchers drew up plans to produce 130 million infected mosquitoes per month. And they developed sophisticated delivery systems - including open-field tests on an unsuspecting American public (albeit with uninfected vectors). A partially declassified "Entomological Warfare Target Analysis" from this time shows that the US Army was considering attacks on Soviet cities with yellow fever mosquitoes. The report concluded that it "would be impossible for a nation such as the USSR to quickly undertake a mass immunization program to protect millions of people." But surely we could amass such a public health campaign today, right? Based on a natural experiment with an insect-borne virus, things don't look so good. When linkurl:West Nile virus; arrived in 1999, government agencies scrambled to explain and then control the disease. The technological might of the United States could not keep mosquitoes from spreading the disease across the nation.

Given our losing battle against West Nile virus, the greatest concern is its African cousin, linkurl:Rift Valley fever.; This virus causes abortions in pregnant livestock, and young animals suffer 10 to 70 percent mortality. In 1977, a strain able to invade the human nervous system emerged in Africa. Of 200,000 Egyptians who fell ill, some 2,000 lost their eyesight and 598 died of linkurl:encephalitis.; Every region in the United States has a mosquito species capable of transmitting this disease. Nor would it be difficult to introduce Rift Valley fever, according to linkurl:Charles Bailey,; director of the National Center for Biodefense at George Mason University. A person with $100 worth of supplies, a set of simple instructions, and a plane ticket from an afflicted African nation to the United States could introduce the disease with virtually no chance of being caught. All of this might sound like post 9/11 hyperbole but for the history of insect weapons in the 20th century. We might doubt the Cuban, Chinese, and North Korean accusations that the United States launched attacks with a menagerie of insect vectors during the Cold War, but there is no doubt that Japan's Unit 731 waged full-scale entomological warfare against China in World War II - and were on the verge of launching similar attacks against US troops and the American public. Between linkurl:plague-infected fleas; and linkurl:cholera-coated flies,; nearly half-a-million Chinese were killed.

Is the United States prepared for an entomological attack? Not according to linkurl:Robert Kadlec,; staff director for the U.S. Senate Subcommittee on Bioterrorism and Public Health. He argues that rather than amassing defenses along our borders, we should fund a flourishing public health system that can detect and quash whatever comes. A great strategic lesson of 9/11 has been overlooked. Terrorists only need a little ingenuity, not sophisticated weapons, to cause enormous damage. Armed only with box cutters, the terrorists hijacked planes and brought down the towers of the World Trade Center. Insects are the box cutters of biological warfare-cheap, simple, and wickedly effective. __...Sensing the air currents, a cloud of mosquitoes pours through the window, carrying a payload of yellow fever. The city's tropical heat, stagnant waters, crumbling infrastructure, decrepit health care system, and haggard people - nearly a quarter million resolute souls after linkurl:Katrina; - will provide an ideal setting for an epidemic. The man pulls a cell phone from his pocket and reads the coded text messages from his associates in Houston and Miami. He smiles, brushes a mosquito from the key pad, and dials the news desk at CNN.__ linkurl:Jeff Lockwood; is the author of __Six-Legged Soldiers: Using Insects as Weapons of War__.

Biological warfare response is public health. Period. Kadlec is right.

The Mediterranean Fruit Fly has been completely controlled by release of irradiated males the few times that this fruit fly became established in California.\n\nThe method could be, and is, being used for a number of different insect pests. It would not take very much of the budget now given to the U.S. Department of Defense to become prepared for released invasions of the most dangerous carriers of diseases. \n\nAt present the International Atomic Energy Agency in Vienna is most active in helping different nations in control of insect pests. \n\nI am working with the IAEA now to gain information on how to control the Mountain Pine Beetle that has devastated a pine forest the size of California in British Columbia, Canada. This beetle has curious mating habits that still have to be taken into consideration. \n\nR.C. von Borstel
