Bug Birth Control Tested; Mosquitoes Now Guinea Pigs
NEW YORK, — (UPI)— The two most promising of the experimental Chemosterilants" have been put to the acid test of whether they sterilize the male mosquito permanently or merely for the time being.
One flunked it ingloriously while the other passed it more or less, but much more than less. The test was critical because it would be uneconomical to sterilize a male on anything other than a permanent basis.
"Chemosterilants" are science's potential better-mouse-trap for controlling obnoxious insects. The current control method of poisoning them is under criticism because it can poison birds, fish and even people.
EUT THE EXPERIMENTAL "Chemosterilants" promise to be harmful only to insects, and harmful to them only by preventing them from reproducing. It is a less dramatic method than killing but in the long run it would be no less effective.
The two most promising are "Apholate" and "Tepa," those names being extreme simplifications of extremely complicated chemical definitions. In the Entomological Research Laboratories of the U.S. Department of Agriculture in Gainesville, Fla., they were applied to the males of the common mosquito, Aedes Aegypti.
Students Assist KC Voter Drive
KU students enlisted the names of about 150 prospective Kansas City voters in a voters registration drive in Kansas City, Mo., Saturday, Elbert J. Rinkel, Scott City junior, said.
The purpose of the drive is to register voters for a city election on a public accommodations ordinance to be held April 7, Rinkel said.
Rinkel said that about 20 members of the Kansas City Liberal Action Committee and about 15 members of the KU-Y participated in the drive, sponsored by church organizations and civil rights groups in Kansas City.
Rinkel, president of the Kansas University Liberal Action Committee, said that KULAC is sending several of its members to Kansas City again this weekend to help register voters for the election.
Rinkel considered the voter registration drive a worthwhile project and said he was pleased with the results. The students visited homes and took the names of people who said they would like to register, Rinkel said.
The church and civil rights organizations sponsoring the project will provide rides to people who said they would like to register for the election. Rinkel said.

Of the eggs laid by the first females exposed to "Apholate"-treated males, not quite five per cent were hatchable. But the eggs of the fourth batch of females exposed to them were 85 per cent hatchable, and this is the ratio of hatchability which occurs in natural mosquito breeding.
They were added to the tap water in which mosquito larvae were developing. When the males emerged into adult form, they were exposed consecutively to four bathes of females. The tests were to determine whether the females subsequently laid hatchable eggs.

The eggs of the first batch was only half of one percent hatchable. In the second batch the hatchability rate rose to one and one-half per cent, and in the third it bounced up to eight and one-half per cent only to fall back to about

two and a half per cent in the fourth.
Furthermore, the amounts of "Chemosterilants" applied to the water in which the males spent their larva stage was tiny—only 10 parts chemical to 1 million parts water.
David A. Dame and Hugh R. Ford, the entomologists in charge, also showed experimentally that "Tepa" applied to male mosquitoes after they reached adulthood resulted in 100 per cent permanent sterilization. In this connection it must be remembered that applying a "Chemosterilant" to mosquito-breeding bogs would be much easier than getting it into fully developed animals.
