Aphids severely affect crop production by transmitting many plant viruses. Viruses are
obligate intracellular pathogens that mostly depend on vectors for their transmission and
survival. A majority of economically important plant viruses are transmitted by aphids. They
transmit viruses either persistently (circulative or non‐circulative) or non‐persistently. Plant
virus transmission by insects is a process that has evolved over time and is strongly
influenced by insect morphological features and biology. Over the past century, a large body …
