Recently Williams has been work ing with hormones that are secreted by insects to permit and regulate growth and maturation from egg to larva to pupa to adult. If insect juvenile hor mone comes in contact with larvae at the wrong stage of development, the in sects will not mature. When insects at later stages are treated with growth hor mone, they are killed by developing at too rapid a rate. Moreover, Williams .and other researchers have discovered that lethal equivalents of these sub stances have...

The reason that all insects are not wiped out in the Rio Negro area is that not all of them come into contact with the insecticide-laden river.
