During 1994/1997, the population dynamics of the quarantine glasshouse leafminers Liriomyza bryoniae and Liriomyza huidobrensis were studied using yellow sticky strips in glasshouses at Tvrdonice (near Břeclav). There were usually three generations per growing season. An interval of about 28 days can be recognized between the peak periods for adults, which corresponds with the development time for these leafminers under the local temperature conditions. During 1995/1997, three polyphagous glasshouse Liriomyza spp. were recorded in the Czech Republic outside glasshouses: the native palaearctic species L. bryoniae in 17 samples (eight squares of grid map), Liriomyza strigata in 10 samples (five squares of grid map) and the originally nearctic and neotropical quarantine pest L. huidobrensis in five samples (three squares of grid map). The host plants were broad bean for Liriomyza bryoniae (three times), onion for L. huidobrensis and broad bean (three times) and poppy for L. strigata. Overwintering of puparia of L. huidobrensis outdoors in the Czech Republic seems barely possible.
