麦长管蚜在燕麦上的取食行为‘’克林特兰‘’)进行了电子监测，并描述了与流涎、摄取和筛分元素渗透相对应的波形。在进入植物的90分钟内，蚜虫从韧皮部摄取的时间为0-43分钟(平均8.1min)，从非韧皮部摄取的时间为0-60分钟(平均为19分钟)。只有65%的受试者在90min内接触韧皮部，在18-85min(平均32min)后接触韧皮部。携带大麦黄矮病毒(BYDV)的蚜虫取食行为与非带毒蚜虫的取食行为没有显著差异。筛网元件的穿透是BYDV传播的先决条件，但不能确保传播。一个筛分分子的穿透导致65%的传递率，与韧皮部接触的时间无关。传播的机会随着筛元穿透次数的增加而增加。在燕麦幼苗上接种一种带毒力的蚜虫90分钟，估计会导致54%的植株被感染。此外，据估计，在工厂接入周期短于17分钟的情况下，不会发生任何传播。
Feeding behavior of Sitobion avenae F. (Homoptera: Aphididae) on oats (Avena sativa cv. ''Clintland 64'') was electronically monitored, and waveforms corresponding to salivation, ingestion, and sieve element penetration described. During 90 min plant access, aphids ingested from phloem for 0-43 min (mean: 8.1 min) and non-phloem for 0-60 min (mean: 19 min). Only 65% of the aphids tested made phloem contact within 90 min, contacting phloem after 18-85 min (mean: 32 min). No significant differences was observed in the feeding behavior of aphids carrying barley yellow dwarf virus (BYDV) from that of non-viruliferous aphids. Penetration of a sieve element was a prerequisite for BYDV transmission but did not insure transmission. Penetration of one sieve element resulted in a 65% chance of transmission independent of the duration of phloem contact. The chance of transmission increased with increasing number of sieve element penetrations. Inoculation of oat seedlings with single, viruliferous aphids for 90 min is estimated to cause 54% of the plants to be infected. Also it is estimated that no transmission can occur with plant access periods shorter than 17 min.
