Sieve element acceptance by aphids
- N/A
Aphis fabae took 3 to 4 hours, after access to a plant, to show the first puncture of a sieve element. A further hour was needed before sustained ingestion started. Early probes did not show sieve element punctures, in general. Within later probes, showing these punctures, the average time needed to reach them was 30 min. Early sieve element punctures were mainly accompanied by the secretion of a watery saliva. The composition of this saliva and the function of its secretion is unknown. It is speculated that this saliva secretion makes the phloem sap more readily available and/or improves its quality for aphids. Further research is needed to test this hypothesis.
