Plant Parasites of Europe

leafminers, galls and fungi

Smynthurodes betae

Smynthurodes betae Westwood, 1849

on Pistacia, primary host plant


There are two types of galls. The fundatrix lives in a small red gall in the midrib. The secondary gall of her offspring is a 2 cm long, strongly swollen, reddened upwards fold of the leaf margin bordering the petiole; also the lateral veins are clearly swollen here.

host plants

Anacardiaceae, narrowly monophagous

Pistacia atlantica, chinensis subsp. integerrima.

Rarely also P. vera.

polyphagous on secondary host plants


Winged adults that emerge from the Pistacia galls settle on the roots of a variety of plants. Here several generations take place, until a generation on Pistacia follows in the end; the entire cycle takes two years; however, see below.

host plants

± dicotyledons, polyphagous

Artemisia; Arctium; Beta; Brassica napus, oleracea; Capsella; Diplotaxis erucoides; Drimia maritima; Gladiolus; Gossypium; Heliotropium; Lycopersicon esculentum; Phaseolus vulgaris; Raphanus raphanistrum; Rumex; Sinapis arvensis; Solanum nigrum, tuberosum; Trifolium; Vicia

Rarely also Cyperaceae, Poaceae.


The species has an almost world-wide distribution. In all regions where Pistacia does not occur the species lives permanently on the secondary hosts.
