What is the primary sustenance consumed by yellow aphids that fuels their rapid reproductive cycle?
Answer
Phloem sap
The primary sustenance for all aphids, including yellow varieties, is phloem sap. This sap flows within the plant's vascular system and is inherently rich in sugars, which are the direct result of photosynthesis. This high-sugar content provides the necessary energy reserves for the aphid's incredibly rapid multiplication rate. Aphids are obligate plant-suckers, relying entirely on this internal fluid rather than consuming solid leaf matter.
