Liriomyza trifolii (Burgess in Comstock, 1880)


Rather long, narrow, strongly convoluted, not strongly widening, upper-surface gallery, often ending in a secondary blotch. Frass in thread fragments at either side. Mines often in the distal part of the lamina. Pupation outside the mine.

distribution within Europe

The first records of the species come from North and South America. Transported over practically the entire world in the eighties by the trade in cut flowers (chrysanthemums). In temperate regions mainly in greenhouses (Dempewolf, 2004a).


Front spiraculum with 6 papillae, rear spiraculum with 3, the outer ones somewhat elongated. Contrary to L. bryoniae the larva is entirely yellow (Minkenberg & van Lenteren, 1986a).


Yellowish brown.


Liriomyza phaseolunulata (Frost, 1943); L. alliovora Frick, 1955.

In many older publications (including Hering,1957a) but also Stammer (2016a) the name trifolii is used to denote what presently is named Liriomyyza congesta. The “L. trifolii” in van Frankenhuyzen Houtman & Kabos (1982a) is a mix of congesta and trifolii.


Very serious pest species, in temperate regions mainly in greenhouse crops, in the tropics and subtropics also in the open. The species is particularly dangerous because it quickly has developed a high degree of resistance against a variety of insecticides (Spencer, 1973b; Minkenberg & van Lenteren, 1986a; Darvas, Skuhravá & Andersen, 2000a).
