Entomopathogenic fungi were collected from soil in four adjacent habitats (oak forest, agricultural soil, pine reforestation and chaparral habitat) Saltillo, México using the insect bait method with Tenebrio molitor (L.) (Coleoptera: Tenebrionidae) larvae as bait. Overall, of exposed to 171 (20%) hosted Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae), 25 (3%) Metarhizium anisopliae (Metschnikoff) Sorokin Clavicipitaceae) 1 (0.1%) Isaria (=Paecilomyces) sp....

Abstract Invasive species are a leading cause of global biodiversity decline. Larvae the cactus moth Cactoblastis cactorum Berg (Lepidoptera: Pyralidae: Phycitinae) consume prickly pear ( Opuntia ; Cactaceae) in its native South American range. High host specificity made C. an appropriate biological control agent species, which have become invasive weeds around world. This program was successful. Ironically, success weed facilitated series events led to invasion North America where diversity...

The subphylum Entomophthoromycotina (Phylum Zoopagomycota) includes many arthropod pathogens, some of which are renowned for their abilities to alter host behavior prior death and cause epizootics that impact populations. last checklist arthropod-pathogenic species in this group was published 1963 consisted 39 a single genus. Since then, more have been named, taxonomy has changed extensively. We constructed an updated North America; the continental United States, Canada, Mexico. Data were...

Novel trophic associations have sometimes resulted in fortuitous and significant biological control. After the invasion of North America by South American cactus moth, Cactoblastis cactorum (Berg) (Pyralidae: Phycitinae), it is pertinent to characterize assemblage local natural enemies that could utilize this moth new host-parasitoid associations. Herein we report on Apanteles mimoristae Muesebeck (Braconidae: Microgastrinae), a gregarious endoparasitoid wasp attacking caterpillar phycitine...

Diaphorina citri Kuwayama (Hemiptera: Liviidae) is a vector of Liberibacter asiaticus Jagoueix et al. and americanus Teixeira al., causal agents the critical yellow dragon disease or Huanglongbing (HLB), which affects citrus production worldwide. Recently, green synthetic nanoparticles have emerged as potential alternative to control agricultural insect pests. The insecticide effect silver (AgNPs) on 2nd instar nymphs D. under laboratory greenhouse conditions was evaluated. Mortality...

The painted bug or bagrada bug, Bagrada hilaris (Burmeister) (Hemiptera: Pentatomidae), is a key pest of crops in the family Brassicaceae. In this work, three species Scelionidae (Hymenoptera) are reported for first time as parasitoids eggs Mexico, at Saltillo, state Coahuila: Gryon myrmecophilum (Ashmead), Telenomus podisi Ashmead and Trissolcus basalis (Wollaston). This also report widespread genus an egg parasitoid B. outside India. Total percent parasitism, high resolution images, CO1...

The tomato red spider mite Tetranychus evansi Baker and Pritchard is a pest of primary importance on cultivated Solanaceae in some countries. Based morphological characters sequencing fragment the cytochrome oxidase subunit I (COI) mitochondrial DNA (mtDNA), presence T. reported for first time Mexico, from four municipalities (counties) three states: Baja California, Nuevo León Tamaulipas, solanaceous plants, both (tomato, Solanum lycopersicum L., potato tuberosum L.) wild (nigthshades, cf....

Athel, saltcedar, siempreverde, rompeviento, or pinabete (Tamarix aphylla (L.) Karsten) is an exotic ornamental tree important for shade and wind protection in northern Mexico. There, the defoliated by Diorhabda beetles, especially subtropical tamarisk beetle, sublineata (Lucas), introduced biological control of other invasive, shrubby Tamarix spp. The damage conspicuous Mexican communities Rio Grande Conchos River basins, Chihuahua State. To protect athel trees against D. sublineata, we...

Liberibacter-caused Huanglongbing disease vectored by the Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), has spread to most citrus-growing areas worldwide. In Mexico, research efforts manage and slow its have intensified since it was detected there in 2009. Integration of microbial control with other management practices should be investigated for D. (Meyer et al. 2008, J. Invertebr. Pathol. 99: 96–102). To that end, we assessed impact applications entomopathogenic...

Information is provided on Auchenorryncha entomofauna from a grape (Vitis vinifera L.) vineyard at the Municipality of Parras, Coahuila. Two families, five subfamilies, 14 genera, and 17 species were collected, are first data for this region. No tested positive Xylella fastidiosa (Wells et al., 1987) (Xanthomonadales: Xanthomonadaceae) bacteria. However, Balclutha mexicana (Blocker, 1967) (Hemiptera: Cicadellidae) was Candidatus Phytoplasma asteri (Lee al. 2004) (Acholeplasmatales:...

The potato psyllid Bactericera cockerelli (Šulc) (Hemiptera: Triozidae) is a pest of solanaceous crops (order Solanales), including (Solanum tuberosum L.) and tomato (S. lycopersicum L.). Feeding by high populations nymphs causes yellows while adults are vectors the plant pathogen 'Candidatus Liberibacter solanacearum'. Foliar symptoms that were consistent with either 'Ca. L. solanacearum' infection or observed in 2019 on tomatillo (Physalis ixocarpa Brot.; family Solanaceae) grown within an...

La falta de información sobre plantas hospedantes silvestres Bactericera cockerelli ha limitado la comprensión ecología y fenología del insecto el papel real estas en dinámica enfermedad. Debido a vectorización bacteria fitopatógena Candidatus Liberibacter solanacearum (Lso), B. es una las plagas más importantes cultivos solanáceas. En este documento, se reporta que está asociada con planta huésped silvestre no enlistada, Margaranthus solanaceus Schltdl., llanuras bajas noreste México. Se...

The fungus-growing ants (Hymenoptera: Formicidae: Attini) of northeastern Mexico are poorly known. Herein new distributional records in NE and habitat observations provided for the Apterostigma mexicanum Lattke, Atta texana (Buckley), Cyphomyrmex rimosus (Spinola), Mycocepurus smithii Forel, Mycetosoritis hartmanni Wheeler, Sericomyrmex aztecus Trachymyrmex smithi Buren, turrifex Wheeler.

This study compared the insecticidal activity of liquid culture-produced blastospores and solid substrate-produced aerial conidia Beauveria bassiana GHA Isaria fumosorosea ARSEF3581 strains against Diaphorina citri adults. Insects exposed to 107 propagules/ml in a spray residue contact leaf bioassay died within 6 days at 25°C, with no significant differences between fungal treatments. At higher concentrations (108 propagules/ml), I. killed psyllids faster its blastospore formulation, i.e. 4...
