Cytoplasmic Incompatibility 

New Weapons Found To Battle Insects  The insect has always been a voluble provider of basic facts for the geneticist. Now the geneticist is using this knowledge against the insect.The campaign is not yet directed against the ubiquitous laboratory (house) fly, but the insect vectors of diseases such as malaria, filariasis, yellow fever, and plague. A World Health Organization scientific group met recently in Washington to review new genetic tools for vector eradication.Perhaps most encouraging of the recently-tried genetic methods is "cytoplasmic incompatibility." Recently the technique was used to completely eradicate a carrier of filariasis, Culex fatigans, from a Burmese village.The protagonists were a group of the flies imported from Fresno, Calif, explained Professor Hannes Laven. About 50 pairs of a species related to the Burmese mosquitoes were sent to Dr. Laven's laboratory at the Johannes Gutenberg University in Mainz. The California insects were crossbred for
