Chrysomela knabi

In a study of insect-plant relationships at Oak Ridge National Laboratory, Crossley (1963) utilized a field nuclear waste site containing Cs. Chrysomela knabi beetle larvae were collected on leaves from willow trees (Salix nigra) growing on White Oak Lake bed. This lake was formerly a low-level waste disposal site at the laboratory, and the sediments contained various radionuclides, including Cs. Consequently, the leaves of the willow tree contained Cs...

Third instar larva, pupa, and adult stages are shown, (b) Retention of Cs by a single grasshopper Melanoplus differentUdis. (c) Relationship of insect weight to biological half-life of cesium.
