The Ecuadorian Agromyzidae described by Theodor Becker from the Mission du service géographique de l'armée pour la mesure d'un arc de méridien équatorial en Amérique du Sud are revised and several taxonomic changes are proposed. The eight named species identified by Becker actually comprise 14 species of Agromyzidae (3 Melanagromyza, 4 Cerodontha, 6 Liriomyza, 1 Nemorimyza) and one species of H...

Liriomyza mystica Boucher & Nishida, sp. n., and Liriomyza prompta Boucher & Nishida, sp. n. are described from Costa Rica. Both species were reared from leaves of Bocconia frutescens L. (Papaveraceae). The latter species was also reared from B. arborea S. Watson. Larvae of L. mystica mine primary veins of large, relatively old, mature leaves, and L. prompta mine blades of small to large, matur...

Liriomyza huidobrensis (Blanchard) is a highly destructive invasive leafminer pest currently causing extensive damage to vegetable and horticultural crops around the world. Liriomyza langei Frick is a leafminer pest native to California that cannot currently be morphologically distinguished from L. huidobrensis. We used a DNA-barcoding approach, a published PCR-RFLP method, and a new multiplex ...

DNA barcoding involves the sequencing of a single gene region from all species to provide a means for identifying all of life. Although appealing to many scientists, this idea has caused considerable controversy among systematists. We applied a DNA barcoding approach to outbreak populations of invasive Liriomyza spp. leafminer pests in the Philippines to explore the use of barcoding in a relati...

Liriomyza huidobrensis (Blanchard) is native to South America but has expanded its range and invaded many regions of the world, primarily on flowers and to a lesser extent on horticultural product shipments. As a result of initial invasion into an area, damage caused is usually significant but not necessarily sustained. Currently, it is an economic pest in selected native and invaded regions of...

The pea leafminer, Liriomyza huidobrensis (Diptera: Agromyzidae), is a highly polyphagous insect pest of global distribution. L. huidobrensis feeds and lays its eggs on leaf tissue and reduces crop marketability because of stippling and mining damage. In field insecticide trials, it was observed that stippling was reduced on plants treated with surfactant alone. The objectives of this study wer...

In recent years, the pest status of Liriomyza trifolii (Burgess) and L. huidobrensis (Blanchard) (Diptera: Agromyzidae) has changed in California, as well as other areas of the world. In California, L. huidobrensis has become the predominant Liriomyza species in valleys along the central coast, while L. trifolii remains the predominant species in southern California. To investigate possible rea...

Liriomyza leafminers (Diptera: Agromyzidae) are cosmopolitan, polyphagous pests of horticultural plants and many are resistant to insecticides. Producers in South Texas rely on insecticides as the primary management tool for leafminers, and several compounds are available. The objective of this study is to address the efficacy of these compounds for controlling Liriomyza while minimizing their ...

Photoactive compounds might be used as effective pesticide agents, with almost no impact on the environment, being nontoxic and not mutagenic. The point is, that nontoxic photoactive compound accumulates within the insect body and, following exposition to visible light, induces lethal photochemical reactions and death of target pest. The aim of this study was to determine, whether hematoporphyr...

The leafmining ßyLiriomyza trifolii (Burgess) (Diptera: Agromyzidae) is an important pest of vegetable and cut-ßower crops. In recent decades, this species has become invasive, spreading from the Americas to the rest of the world. Despite substantial losses caused by Liriomyza leafminers, the systematics of these ßies has remained poorly understood because of their small size and morphological ...
