Aggregation in Aphis varians: an effective strategy for reducing predation risk

, : Aggregation in Aphis varians: an effective strategy for reducing predation risk. Ecology (Washington D C): 704: 1008-1016

The advantages or disadvantages of clumping to prey was studied for the interaction between Aphis varians and the coccinellid Hippodamia convergens on fireweed (Epilobium angustifolium) in Washington during 1986-87. Aphids tended to stay within clumps of conspecifics.

The exposure of cultured rat striatal neurons to L-DOPA caused marked cell death. The L-DOPA cytotoxicity was inhibited by the addition of Mg2+ to and by the removal of Ca2+ from the culture medium, and also by the application of tetrodotoxin. Mor...
