Liriomyza bryoniae (Kaltenbach, 1858)
< back | next >
forms contorted mines

 

Food Plant: Dahlia pinnata (Dahlia), Hydrocotyle spp. (Pennyworts), Cucumis sativus (Cucumber), Phaseolus spp. (French and Runner Bean), Lupinus spp. (Lupins), Galeopsis spp. (Hemp Nettles), Linaria spp. (Toadflaxes), Atropa belladona (Deadly Nightshade), Lycopersicon esculentum (Tomato), Solanum villosum (Red Nightshade)

Egg: inserted mainly into the upper leaf surface

Mine: June-September

Notes: A major pest species on a large range of species, which forms irregular twisting mines (as shown), which are not associated with the veins or midrib of the leaf (It is this character which enables distinction from another Agromyzid pest species - Liriomyza huidobriensis). The larvae may leave one leaf (if not large enough) and enter another leaf, via the petiole). It exits the leaf to pupate through a semi-circular slit in the upper surface of the leaf. Highly polyphagous and mainly restricted to greenhouses and botanical gardens, where it is a particular pest of Tomatoes. Large infestations can cause reduced fruit yield and even death of the plant. Found throughout Europe. Mines are shown on Capsicum annuum.

Data: 17.ix.2010, Bresso (Milan), Italy
