Los muestreos se hicieron de junio a septiembre de 2017 en siete huertas de nogal, tres huertas con manejo orgánico y cuatro con manejo convencional. Los muestreos de suelo se hicieron en 31 sitios, en cada uno se tomaron muestras a tres profundidades: 00-30, 30-60, 60-90 cm, cada una se colocó en bolsas plásticas etiquetadas. Para el muestreo foliar, se tomaron muestras al azar en 25 árboles en cada huerta, se colectaron 100 foliolos ubicadas en la parte media del brote del año, todos los foliolos se colocaron en bolsas de papel etiquetadas. Todas las muestras se enviaron al laboratorio para determinar las propiedades del suelo y contenido nutricional de los macros y microelementos presentes. Los resultados indican que los suelos de la Región Norte son altamente salinos, muy altos en Contenidos de Carbonatos totales (68%), Capacidad de Intercambio Catiónico (27.5 meq/100 gr), pH fuertemente alcalino (8.10-8.97), deficientes en N, P, Fe y Zn. En relación a los elementos en el follaje, se encontró que la mayoría se encuentra dentro de los Rangos de Suficiencia Nutricional reportados para dos regiones con condiciones edáficas similares a la Región Norte de Coahuila. Lo anterior posiblemente por las aplicaciones de nutrientes minerales durante el ciclo vegetativo de este frutal.

Smith) (Lepidóptera: Noctuidae), is the most important insect pest of maize, Zea mays L., because it causes great economic loss and insecticide to be overused for its control, which increase costs of production and contaminate the environment. However, the pest is naturally controlled by various parasitoids of the Tachinidae family. Here, we report molecular identification of a new species of the genus Lespesia parasitizing larvae of S. frugiperda in the central region of Chiapas, México.

The Tetranychidae family distributed worldwide has 1,321 species of mites known on 3,917 plants (... more The Tetranychidae family distributed worldwide has 1,321 species of mites known on 3,917 plants (Migeon and Dorkeld 2019) in more than 70 genera of two subfamilies, Bryobinae and Tetranychinae. Most agricultural pests are Tetranychinae (Zhang 2003, Hoy 2011). Migeon and Dorkeld (2019) mentioned 154 species in the genus Tetranychus Dufour (Trombidiformes: Tetranychidae) throughout the world. Red spider, Tetranychus merganser Boudreaux, is an important agricultural pest worldwide. The mite distributed in China, USA, Australia, and Mexico has been reported on apocynaceous, aquifoliaceous, cactaceous, caricaceous, cucurbitaceous, euphorbiaceous, leguminoseous, moringaceous, oleaceous, ranunculaceous, rosaceous, and solanaceous plants (Chacó-Hernández et al. 2020). Feeding by mites destroys epidermal tissue, parenchyma, and chloroplasts of leaves of host plants and is observed as small white spots near leaf veins, and with severe infestation, the spots can fuse, covering all the leaf (López 2014, López-Bautista et al. 2016, Montelongo-Ruíz et al. 2020). This scientific note reports two new hosts of T. merganser: Helietta parvifolia Gray Benth (Rutaceae) and Pittosporum tobira (Thunb.) W.T. Aiton (Pittosporaceae) in Tamaulipas State, México. H. parvifolia was observed in Peregrina Canyon in Protected Natural Area “Altas Cumbres” (23° 46' 41'' N y 99° 12' 12'' W, 365 m above sea level) where 50 leaves were collected on 10 January 2020. The second host, P. tobira, was in an urban area of Victoria City (23° 42' 54'' N y 99° 10' 48'' W, 448 m above sea level) where 30 leaves were collected on 1 February 2020. Leaves of H. parvifolia and P. tobira damaged by mites were observed with a 30-x magnifying loupe. Specimens of mites were preserved in 70% alcohol and transported to the Population Ecology Laboratory of the Institute of Applied Ecology of the Autonomous University of Tamaulipas at Victoria City, Tamaulipas State, Mexico. Forty-five mites were collected from H. parvifolia leaves and 20 mites from

As a result, two different species have been described under the same name, ‘Amphibolips kinseyi’. To solve this homonymy, a new name Amphibolips comini Cuesta-Porta & Pujade-Villar, nom. nov. is proposed for replacing A. kinseyi Cuesta-Porta & Pujade-Villar, 2020, a junior homonym of A. kinseyi Nieves-Aldrey & Castillejos-Lemus, 2020. Accordingly, new keys for adults of the Amphibolips ‘nassa’ species-complex and their associated host galls, including all known species from Mexico and Central America are provided.

The aims were to determine the type and other characteristics of functional response including predatory capacity of green lacewing for possible use in augmentative biological control in apple (Malus x domestica Borkh; Rosales: Rosaceae) orchards where obliquebanded leafroller was recently introduced in Mexico. Abundance of the pest increased rapidly, causing significant foliar damage and some fruit blemish. Third-instar green lacewing larvae based on logistic regression analysis showed Type II functional response to four densities of single-instar larvae of obliquebanded leafroller. Among the five instars of prey, the largest average number consumed per green lacewing predator was a relative density of four second-instar larvae at a rate of 1.93 in 24 hours. Also, substantial average consumption was by two thirdinstar prey larvae per predator whereby an average of 1.5 third-instar obliquebanded leafrollers were consumed per third-instar green lacewing in 24 hours. The third-instar predator captured and consumed third-instar prey larvae in the shortest handling time (h), i.e., only 6.46 minutes, whereas the handling times for the other instars ranged from 23.48 minutes for the fifth instar to 31.56 minutes for the fourth instar. However, attack coefficients (a) of green lacewings were slightly greater for third-and fourth-instar prey larvae, with 0.19 hour (11.4 minutes) and 0.15 hour (9.0 minutes) until the first attack, respectively, compared to 0.09-0.11 hour (5.4-6.6 minutes) until the first attack for the other instars. Results indicated that the green lacewing could be considered a prospective candidate for use as a biological control agent against lepidopteran leafrollers.

Red spider mite, Tetranychus merganser Boudreaux (Acari: Tetranychidae), has increased its host plants and causes severe damage and defoliation. Control of pest mites depends mostly on the use of agrochemicals. Mite-resistant plants are needed. Piquin chili, Capsicum annuum var. glabriusculum (Dunal) Heiser & Pickersgill, is a wild species of chili pepper and a major source of phytochemical compounds such as phenolic compounds, flavonoids, capsaicinoids, carotenoids, tocopherols, ascorbic acid, and volatile compounds. The aim of this study was to evaluate antibiosis and antixenosis as resistance mechanisms in three accessions (BGH-425, BGH-426, and Ch) of piquin chili in laboratory and greenhouse conditions. In the laboratory, antixenosis was evaluated by non-preference for oviposition, antibiosis by infinitesimal rate of increase (r) and finite rate of increase (λ), and repellency by percentage of mites killed. In the greenhouse, antibiosis was evaluated by r and λ. Preference for the lower or upper leaf surface was evaluated. Antixenosis, antibiosis, and repellency were observed in the three piquin chili accessions. In the laboratory, females survival was 60, 80, 80 and 93.33% on BGH-426, BGH-425, Ch and bean (Phaseolus vulgaris L.), respectively. The lower r was observed on Ch accession (0.3857 day-1) and the higher on bean (0.6105 day-1). The λ ranged from 1.47 on Ch to 1.84 on bean. In the greehouse, the highest and the lowest values of the r y λ were obtained at bean (0.6014 day-1 and 1.82) and Ch accession (0.3591 day-1 and 1.43), respectively. Red spider mite preferred to colonize the lower leaf surface of the three piquin chilis and bean. The three accessions of piquin chili were most resistant to T. merganser.

Britton & Rose (Cactaceae) and Myrtillocactus geometrizans (Mart. Ex Pfeiff.) (Cactaceae) in North-Central Mexico. The purple scale has been reported on plants representing 56 genera in 40 families and is distributed in various countries, including Mexico (Garcı́a-Morales et al. 2016, http://scalenet.info/catalogue/ Lepidosaphes%20beckii/). In Mexico, L. beckii has been reported in Ciudad de Mexico, Colima, Nayarit, Sinaloa and Veracruz in citrus-growing areas (Miller 1996, Proc. Entomol. Soc. Wash. 98: 68–86; Garcı́a-Morales et al. 2016) and on ornamental and shade plants (Garcı́a-Morales et al. 2016). Pachycereus marginatus and M. geometrizans are endemic cactus species in Mexico. Both grow wild: P. marginatus in Colima, Chiapas, Ciudad de Mexico, Guanajuato, Guerrero, Hidalgo, Jalisco, México, Michoacan, Oaxaca, Puebla, Queretaro, San Luis Potosi, Tabasco, Tlaxcala, Veracruz, and Zacatecas states and M. geometrizans in Aguascalientes, Durango, Guerrero, Guanajuato, Hidalgo, Jalisco, Mexico, Michoacan, Nuevo Leon, Oaxaca, Puebla, Queretaro, San Luis Potosi, Tamaulipas, Veracruz, and Zacatecas states. These cacti species possess medicinal properties (Bravo-Hollis 1978, Las Cactáceas de México. Univ. Nacion.

Botanically based insecticides can cause less acute and chronic risk to human health and the environment while controlling, repelling, and/or modifying insect pest behavior to mitigate damage to the human-valued resource. Botanicals can be a management option to reduce reliance on use of synthetic insecticide. Efficacies of botanical powders of rue (Ruta graveolens L.), creosote bush (Larrea tridentata (Sessé & Moc. Ex DC.) Coville), and dense mistletoe (Phoradendron densum Torr. ex Trel.) were evaluated against first-instar larvae of fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), in a laboratory. Fifteen replications were used of dehydrated, powdered, plant foliage from the three plant species at six concentrations of 0.03, 0.06, 0.12, 0.24, 0.48, and 0.96 g and a nontreated check mixed with 12 g of artificial diet. The number of armyworms dead at 10 days after exposure and instar development eve...
