Résumé :
|
The feeding behaviour of five cereal aphid species in wheat seedlings (measured by the time taken by an aphid to penetrate the phloem and the time spent in committed pholem ingestion) and their performance (measured as mean relative growth rates) were determined as a function of hydroxamic acid concentrations in the seedlings. Lower mean relative growth rates and higher times to attain a committed phloem ingestion were associated with higher hydroxamic acid values. Duration of committed phloem ingestion was not influenced by hydroxamic acid values.
