Bean root aphid

Smynthurodes betae is a specvies of aphids. Where the primary host (Pistacia) is found, the bean root aphid goes through its full life cycle, host alternating from Pistacia to numerous secondary hosts, especially in the Asteraceae (Artemisia, Arctium), Fabaceae (Phaseolus, Vicia, Trifolium), and Solanaceae (Solanum tuberosum, Lycopersicon esculentum) - and sometimes on Beta, Brassica, Capsella, Gossypium, Heliotropum, Rumex, and others. Smynthurodes betae can persist on its secondary hosts as anholocyclic parthenogenetic populations. It commonly overwinters in ant's nests. Anholocyclic parthenogenetic populations of Smynthurodes betae are found in most countries of the world, except the coldest parts. This polyphagous aphid goes through its full life cycle in North Africa, Israel, Syria, Iran, southern Crimea, Transcaucasus and Pakistan.
