Common name:

Hosts

Liriomyza trifolii is highly polyphagous and has been recorded from 25 families (Spencer 1990). The most important crops attacked are beans, celery, chrysanthemum, cucumber, gerbera, gypsophila, lettuce, onion, potato and tomato (Spencer 1989).

Key characters

Head with frons and orbits yellow, hind margin of eye largely yellow, at most slightly darkened centrally, third antennal segment yellow, femur yellow with occasional slight brownish striations, mesonotum matt black with grey undertone, both vertical bristles on yellow ground. Wing with last section of CuA1 3-4 times length of penultimate section, wing length 1.2-1.9 mm. Aedeagus: distiphallus with one distal bulb with marked constriction between upper and lower halves. External morphology is very similar to L. katoi and L. yasumatsui. Identification requires examination of male genitalia. Detailed descriptions can be found in Dempewolf (2004), EPPO (2005), Malipatil et al. (2004), Spencer (1965, 1973) and Shiao (2004). Feng et al. (2007) described a rapid molecular test to diagnose L. trifolii. Key diagnostic features are shown in the PaDIL diagnostic images (Malipatil 2007). The larva of L. trifolii forms a tightly coiled, almost blotch-like mine.

Notes

The biology and ecology of L. trifolii (together with other polyphagous Liriomyza spp.) have been reviewed by Minkenberg & van Lenteren (1986), Murphy & LaSalle (1999), Parrella (1982, 1987) and Waterhouse & Norris (1987). Biological  control of leafminers in protected crops has been reviewed by Chow & Heinz (2004) and van der Linden (2004).

In the USA, L. trifolii  became the dominant agromyzid pest in the USA, displacing L. sativae. This was attributed, at least in part, to its reduced levels of insecticide susceptibility to a wide range of insecticides (Parrella & Keil 1984; Palumbo et al. 1994). However, in Japan, L. trifolii is now being displaced by L. sativae (Abe & Tokumaru 2007), which is attributed to the higher fecundity of L. sativae (Tokumaru & Abe 2003) and to the inability of Dacnusa sibirica, an effective braconid parasitoid of L. trifolii, to complete development on L. sativae (Abe et al. 2005).

Reitz & Trumble (2002) suggested that there may be cryptic species within L. trifolii. They found flies in southern Californian fly populations were polyphagous but that central Californian populations were now restricted to capsicum. They also found that L. langei (the North American clade of L. huidobrensis reinstated to species level by Scheffer & Lewis (2001)) was displacing L. trifolii in central California. Scheffer & Lewis (2006) used cytochrome oxidase 1 sequence variation to detect two major clades (A and W) within L. trifolii. They also concluded that the pepper-feeding flies (from California, Florida, Mexico and Honduras) formed a genetically distinct clade (nested within clade W). All Old World samples of L. trifolii were from clade W, with nearly all (92%) being the same haplotype (T-9), suggesting that invasive populations of L. trifolii came from restricted areas in North America.

In southern Australia, common agromyzids such as L. chenopodii, L. brassicae and Chromatomyia syngenesiae (usually on Sonchus oleraceus) on weeds and other non-crop plants would act as important reservoirs for populations of parasitoids (e.g. Diglyphus isaea (Walker)) of L. trifolii and invasive polyphagous agromyzids (Bjorksten et al. 2005; Lardner 1991).
