ABSTRACT México es de los principales productores de chile, ya que al año se siembran alrededor de 140,000 ha y la producción asciende a 1'180,000 t. En el estado de Sinaloa se establecen, en promedio, 17,180 ha/año, con una producción de 488,153 t. Este cultivo es una importante fuente de empleos y de derrama económica. Se identificaron las especies de minadores de la hoja y su fluctuación poblacional en el cultivo de chile jalapeño en tres municipios del norte de Sinaloa. Se desarrollaron 29 muestreos semanales de octubre de 2008 a abril de 2009. Se contabilizaron minas en foliolos. La fluctuación de adultos se determinó con trampas de impacto color amarillo fluorescente a la altura del cultivo y una trampa fija a 1.70 m. Se determinó taxonómicamente a Liriomyza trifolli (Burgess) mediante claves especializadas. Este agromícido presentó cantidades altas en el municipio de Guasave en comparación con Ahome y El Fuerte, aunque en los tres lotes las poblaciones más abundantes fueron en las etapas de floración y fructificación. Las trampas de altura variable capturaron más adultos del minador de la hoja en los tres lotes, en comparación con trampas fijas a 1.70 m.

    ABSTRACT: The agromyzid leafminers, Liriomyza sativae Blanchard and L. trifolii (Burgess) (Dip-tera: Agromyzidae) are major pests that attack vegetables in Varamin, Tehran Province. The parasitoids (Hymenoptera: Eulophidae) of these pests were investigated during 2003. The leafminer infested leaves were collected from different host plants, in particular cu-cumber (Cucumis sativus L.,) and preserved under laboratory conditions until the parasi-toids emerged. The vegetable leafminer were parasitized by an expected range of parasi-toids. The parasitoid species included Cirrospilus vittatus Walker, Hemiptarsenus zilahise-bessi Erdös, Closterocerus formosus Westwood, Diglyphus isaea (Walker), Diglyphus crassinervis Erdös. and Pnigalio sp. nr. pectinicornis. The most common species was D. isaea, followed by C. formosus and D. crassinervis. Although insecticides were applied con-tinuously for control of leafminers, the mean seasonal percentage of parasitism was 51.12%. The morphological characteristics of each species are given in brief.

    ABSTRACT: There are more than 330 Liriomyza species (Diptera: Agromyzidae) and many are economically important pests of field crops, ornamentals and vegetables. Given the substantial economic losses associated with various aspects of Liriomyza feeding as well as the ability of these insects to rapidly develop resistance to insecticides, researchers from many countries have attempted to use bio-logical control to manage these pests. Unfortunately, progress on the science and implementation of effective Liriomyza biological control is hampered by the literature being scattered widely and in many different languages. A primary goal of this review is to consolidate the available infor-mation and provide an analysis of the published work. Investigations of natural enemies of Liriomyza have identified approximately 140 species of parasitoids, a few species of predators (including nematodes), and some entomopathogens. Some species of parasitoids and nematodes have been mass-reared and used for biological control of Liriomyza species under confined environmental conditions. While chemical control is still used extensively, conservation biological control and inoculative releases are being adopted as a primary strategy for Liriomyza suppression in select situations.

    ABSTRACT: In recent years, the pest status of Liriomyza trifolii (Burgess) and L. huidobrensis (Blanchard) (Diptera: Agromyzi- dae) 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 reasons for this change in status, differences in host plant use and reproductive success of intraspecific populations were examined for Liriomyza trifolii and L. huidobrensis from both central and southern California. The southern L. trifolii fed, oviposited and reproduced successfully on all five hosts tested, but the central population fed significantly less on all hosts and was restricted to reproducing on pepper only. With the exception of pepper, southern L. trifolii had significantly greater larval survival on all hosts than central L. trifolii. In contrast, the central L. huidobrensis population had greater reproductive success than the southern population of that species on all hosts plants tested. However, pepper was not a suitable host for either L. huidobrensis population. Both species showed positive assortative mating, with homotypic mating occurring more frequently than heterotypic mating; however, the difference between L. trifolii populations was much more pronounced than between L. huidobrensis populations. These data indicate that central and southern California populations of each species are distinct biotypes. Furthermore when coupled with previous genetic data, our results suggest the possible existence of cryptic species within L. trifolii.
