...Wald said that the Biolabs, the site of the proposed containment facility, are 50 years old, and ant-infested. Even the most elementary precautions would require insect control, he said, adding he believed the Biolab ants are ineradicable...
...indicate that Lignasan is 99% effective when used preventively-before the disease strikes-on healthy trees. But many plant scientists refuse to endorse the product until they know more about proper dosages, duration of protection and the chemical's effectiveness when used without other preventive measures-such as insect control and prompt, careful pruning or removal of blighted elms. Just as cautiously, Du Pont emphasizes that Lignasan is only an aid for controlling the disease, not a cure...
...Bugs Are Coming" mentions new effective pest-killing innovations but declares that the evolution of the insect will outmode the best of them. It has been suggested that this would not be the case if the various techniques were intermittently applied. When one method is only used for a short time and then replaced with another, evolution of the insect is prevented without destroying the environment...
...sure-fire way of decreasing the number of insects would be to treat them as a valuable natural resource, such as oil and agriculturally produced food. An insect industry would develop, and in 20 years we would face a shortage...

Since the females of many insect species mate only once in a lifetime, bug birth rates can be reduced by tricking them into mating with males that have been sterilized by exposure to radiation. In the 1960s, sterile males were used to eradicate the resident screwworm fly population in Florida and large areas of the Southwest. In a somewhat similar program, Agriculture Department officials in California recently released more than 350 million sterile males and females in an apparently successful attempt to control an invasion of relatively small numbers of the Mediterranean fruit fly. The invaders, mating mostly with...
