Little is known concerning the epidemiology of Toxoplasma gondii infection in people and animals rural Mexico. Serum samples tissues from 150 dogs (Canis familaris), cats (Felis catus), 65 opossums (Didelphis virginianus), 249 rats (Rattus spp.), 127 mice (Mus musculus), 69 squirrels (Spermophilus variegatus) Durango area were evaluated for T. infection. Using a modified agglutination test serum dilution 1:25, antibodies to this parasite found 68 (45.3%) dogs, 14 (9.3%) cats, 11 (16.6%) 66...
Municipal waste is a potential source of infection for Toxoplasma gondii as it may contain contaminated meat with parasite tissue cysts and cat excrement oocysts. Therefore, we sought to determine the prevalence T. associated characteristics in two populations exposed municipal solid Durango, Mexico. Ninety pickers 83 workers Durango City, Mexico were examined infection. They tested anti-T. IgG IgM antibodies using enzyme-linked immunoassays. In addition, socio-demographic behavioural from...
The prevalence of antibodies to Toxoplasma gondii was determined in sera from 105 domestic cats Durango City, Mexico. Using a modified agglutination test, this parasite were found 21% the cats, with titers 1:25 3 1:50 4 1:200 5 1:400 2 1:800 1:1,600 and 1:3,200 or higher cats. Cats older than 1 yr had significantly frequency infection that younger 0.5 (41 vs. 13.2%, respectively; odds ratio = 4.55; 95% CI 1.24– 17.18; P 0.01). Overall, seroprevalence T. Durango, Mexico, is much lower...
Toxoplasma gondii and Neospora caninum are structurally similar parasites, with many hosts in common. The prevalence of antibodies to T. N. was determined sera from dogs Durango City, Mexico. Using a modified agglutination test, were found 52 (51.5%) the 101 titers 1:25 27, 1:50 11, 1:100 5, 1:200 4, 1:400 2, 1:800 1:3,200 or higher 1. Antibodies by indirect immunofluorescent antibody test (IFAT) sp. (NAT). Two had antibodies; these did not have antibodies, supporting specificity tests used....
Se describe una especie nueva de Pleseobyrsa, P. persea n. sp. Costa Rica, cuya planta huésped es Perseaamericana Mill., siendo ésta la segunda del género conocida país y tercera esP. americana (aguacate). describen tanto el adulto como estadio ninfal V; se agrega clave modificada deFroeschner para las especies, ilustran ejemplares en campo, quinto ninfal, los principalescaracteres.
Twelve Metarhizium isolates from Costa Rica, two Honduras and one Nicaragua were characterised using molecular morphological information. Two gene sequences, TEF1-α β-TUB, identified as M. anisopliae, brunneum robertsii, has provided new sequence Eleven SSRs revealed fourteen different genotypes. Morphological variability coincided with allelic diversity within species. This work provides a starting point for the application of integral biocontrol programmes, but more comprehensive detailed...
Introducción. Duponchelia fovealis Z. es una plaga en la producción de cultivos el continente europeo y Estados Unidos. Ha sido detectada fresera Brasil, México finca Cantón Vásquez Coronado, San José, Costa Rica. Objetivo. Determinar presencia distribución fincas freseras Materiales métodos. Durante las épocas secas del 2020-2021 2021-2022, trampas cebadas con feromona D. fueron colocadas reporte inicial Coronado otras seis localizadas principales regiones Rica: La Cima Dota, Llano Grande,...
<p><strong>Background: </strong>The species <em>Megalurothrips usitatus</em> is a thrips insect that has been recorded in Asia, Oceania, Australia and recently America, attacking legume crops.<strong> Objective: </strong>to report as associated with flowers of common bean plants Costa Rica.<strong> Methodology: </strong>the from three growing locations were sampled characterized through light microscopy Rica. Furthermore, phylogenetic...
Over the last decade, high-end fruits such as berries, have faced impact of Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) across Asia, Europe, and Americas. Yet, none countries from Central America has officially reported this pest. We carried out surveys in blackberry fields Costa Rica. placed a proprietary mixture liquid attractants into red-cup traps with lateral holes, it been widely demonstrated best to capture D. suzukii. Subsequently, we collected both adults larvae...
Background The fungus Beauveria bassiana is widely used for agronomical applications, mainly in biological control. B. uses chitinase enzymes to degrade chitin, a major chemical component found insect exoskeletons and fungal cell walls. However, until recently, genomic information on neotropical isolates, as well their metabolic biotechnological potential, has been limited. Methods Eight complete genomes of Neotropical origin three references were studied identify genes its corresponding...

Plutella xylostella es globalmente la plaga más importante en Brassicaceae. Desgraciadamente, su manejo sigue enfocándose insecticidas con poco efecto sobre y altos costos económicos ambientales. Esta investigación buscó confirmar reportes control basado trampeo masivo feromona comparar el costo de esta técnica contraposición aplicación calendarizada insecticidas. Para esto, año 2020, se establecieron seis parcelas experimentales fincas comerciales repollo provincia Cartago, Costa Rica....
Costa Rica has intensified vegetable production by implementing monocultures managed with technological packages (synthetic fertilizers and pesticides). This model sustained in Zarcero, a municipality that supplies fresh vegetables to Rica’s capital surroundings. However, investigations developed the Regional Institute for Studies on Toxic Substances (IRET) have revealed concerning information pesticide use regime area associated adverse effects environment health of inhabitants. In response...
