However, little is known of the biology or ecology of P. polymitus, a potential pest of the agave crop. Fruit of hardy parlor palms are a source of protease inhibitors targeting intestinal enzymes of the evaluated Orthoptera and could be considered strong candidates in future studies for identification and characterization of the inhibitors and their potential use in biological control. … All small-sized insects were males, the medium-size category had 60% females and 40% males, and the large-size category was 100% female. El presente estudio se realizó en la Comarca Lagunera de Coahuila y Durango, México, con el objetivo de evaluar la efectividad de benzoato de emamectina, methoxyfenozide, spinetoram, clorpirifos etil y cipermetrina para el control del gusano barrenador del ruezno (GBR) Cydia caryana Fitch y el impacto en su parasitismo. Entomopathogenic fungi used as biological control agents in different agroecosystems are natural enemies of the insect. 0000015391 00000 n The species has an affinity for Cupressaceae (i.e., 27.3% of occurrences), followed by Rosaceae. In total, 60 specimens were collected, 54 identified to genera, and six to subfamilies Aleocharinae and Pselaphinae. Several anatomical characters to distinguish instars, including body size, body color, and select morphological characters were described. aegypti, Ae. Estos resultados indican que el uso de insecticidas convencionales tuvo un impacto negativo en el parasitismo natural. Piquin chili, Capsicum annuum var. Sorokin, and a commercial strain of Metarhizium acridum (Driver and Milner) were evaluated against S. purpurascens purpurascens, by measuring lethal concentrations 50 and 90 (LC50 and LC90). Once discovered and characterized, native sources of maize resistance to this pest could be effectively integrated with existing control tactics. Maize PI 487903, Ames 28851, and PI 390554 received 14-day scores of ≤6.0 across both years of testing and were considered moderately resistant. The harpactorine assassin bug, Zelus tetracanthus (Stål) (Hemiptera: Reduviidae), is an insect predator frequently found in surveys of saltcedar (Tamarix spp.) Diversity and correlated hawk moth richness and abundance were correlated with mean temperature and rainfall. La mayor abundancia de cicadélidos se registró en febrero - marzo y octubre - noviembre que coincide con los periodos de fructificación y floración. Protease inhibition capacity by fruit of hardy parlor palms (Chamaedorea radicalis Mart.) En México y particularmente en Sinaloa estas prácticas entomológicas son utilizadas con frecuencia en áreas urbanas pero es incierta su aplicación en áreas rurales. The experimental lines are adapted for growth in temperate regions and might provide maize breeding programs with useful levels of resistance to fall armyworm. You will have access to both the presentation and article (if available). The development data contrast with a previous description of Z. socius (= Z. tetracanthus) and illustrate the need to further study the variable morphology, natural history, and genetic makeup of the species. Densidades, Daños y Parasitismo del Gusano Barrenador del Ruezno, Cydia caryana ... Pathogenicity of Metarhizium spp. Se obtuvieron 6,236 especímenes que representan a ocho subfamilias, 21 tribus, 45 géneros, y 40 especies de Cicadellidae. Preference for oviposition by whitefly in two soybean genotypes was evaluated, and a profile of volatile compounds in healthy plants was obtained. Consumption of mezcal in Mexico and its international exportation is increasing. Content Email Alerts notify you when new content has been published. 0000004433 00000 n No se encontró parasitismo en la huerta tratada con clorpirifós y cipermetrina, mientras que donde se aplicaron spinetoram, benzoato de emamectina, y methoxifenozide el parasitismo fue de 2.1% máximo; en los nogales sin tratar el parasitismo fue de 1.5 a 4.3%. Se reporta por primera vez a Zadiprion roteus asociado con Pinus greggi y P. patula en Toluca, Estado de México. bimaculatus, Ae. endstream endobj 2921 0 obj <>/Filter/FlateDecode/Index[92 2799]/Length 74/Size 2891/Type/XRef/W[1 1 1]>>stream The lower r was observed on Ch accession (0.3857 day-1) and the higher on bean (0.6105 day-1). <]/Prev 342703/XRefStm 1570>> Densities were 40-46 and 31-47% lower on Fedearroz 2000, Linea 34, and Altamira 1N varieties than on the most susceptible variety, INTA Dorada, in the first and second field experiments, respectively. 0000004808 00000 n In addition, the systemic insecticides cyantraniliprole, dinotefuran, flupyradifurone, imidacloprid, spirotetramat killed 100% of green peach aphids, thereby eliminating hosts for A. colemani to parasitize. En subfamilias Deltocephalinae y Cicadellinae se concentró el mayor número de especies. Using external morphology to determine the sex of adults of the species is difficult. Soybean, Glycine max (L.), in the field is very susceptible to infestation by sweetpotato whitefly, Bemisia tabaci (Gennadius). The first two were collected on avocado trees, and the third was found in weeds associated with an avocado orchard. trailer Using the device to collect thrips at top strata of trees resulted in less risk to collectors in an effortless way. We report a case in domestic cat, Felis catus Linnaeus, 1758. En este estudio se determinó el ciclo biológico de tres grupos de S. frugiperda, colectados en maíz. Staphylinids were collected throughout 1 year by a Malaise trap at Tula, Tamaulipas, Mexico. 0000003244 00000 n En Tabasco se han reportado 104 especies, 12 pertenecen al género Aedes. Plants were grown in the field in 2018 and 2019, artificially infested with fall armyworm, and leaf damage scores recorded. 0000001798 00000 n Hemipteran insects affecting food and feed safety continue to plague producers of row crops. More isolates are needed and doses and formulations need to be adjusted in future studies to have a pool of biological control options. Individual-based rarefaction curves and sample coverage showed satisfactory hawk moth community. LC50 and LC90 for strain 6MaEM under controlled conditions were 1.7 × 105 and 1.0 × 106 conidia/ml compared to 1.7 × 106 and 7.1 × 106 for strain 9MaEM. Sampling thrips on medium and tall trees has been difficult without appropriate tools. nov., encontrada en Tijuana, Baja California, en hojas de Erionogum fasciculatum Benth. We collected a single female from a pitfall trap in Big Gypsum Valley, Colorado, in July 2012. The objective for this study was to test experimental lines derived from maize germplasm XL370A for resistance to leaf feeding by fall armyworm. The insect pest was discovered in rice in the southern U.S. on multiple occasions, most recently in 2015 and 2018. The three accessions of piquin chili were most resistant to T. merganser. Eleven mangrove forest sites in seven municipalities of the state of Veracruz (Mexico) were sampled, and 10 R. mangle propagules were collected from each site (110 in total). are presented. 0000005788 00000 n The pest has become resistant to several classes of insecticide and Bt-maize grown in some geographical areas. 0000000958 00000 n El gusano cogollero, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), está distribuido en todo el continente americano y recientemente en el continente africano y en Asia. Please select when you would like to receive an alert. During clinical evaluation, the coat was observed to be in poor condition, and alopecia was observed on the sacrum area, perineum, tail, hind legs, and inguinal area, as well as on the face to a lesser extent. fulvus, y Ae. The objective of this work was to contribute to the knowledge of the distribution of the weevil of agave (P. polymitus) in Durango. Sequences obtained, edited, and assembled were compared with those of the National Center for Biotechnology Information (NCBI) database. The average length of trichomes of Nainari was 311 microns and in the experimental line was 342. The objective of this research was to evaluate the effectiveness of Beauveria bassiana (Bals.-Criv.) The most abundant species were Eumorpha satellitia (Linnaeus), Xylophanes pluto (Fabricius), Nyceryx riscus (Schaus), and X. libya (Druce). Inhibition capacity of C. radicalis differed for each Orthoptera species according to the ripening stage of fruit. Pruebas fitoquímicas clásicas comprobaron la presencia de alcaloides, flavonoides, taninos, cumarinas, antracenos, saponinas, triterpenos, y/o esteroides, en DvEM, para identificar los grupos de compuestos presentes y así llevar a cabo la estrategia de separación química. Data from museum collections of Z. tetracanthus suggested the insect has a univoltine life cycle. Native resistance in maize to fall armyworm could enhance existing control tactics. El objetivo de este estudio fue determinar las especies y abundancia estacional de los cicadélidos asociados a plantaciones comerciales de arándano, en Jalisco, México. Los cicadélidos (Cicadellidae) se encuentran entre las plagas que afectan el cultivo de arándano (Vaccinium spp.) El gusano barrenador del ruezno (GBR), Cydia caryana Fitch, es una plaga de importancia primaria del nogal pecanero en Estados Unidos y México, debido a que al alimentarse de nueces pequeñas causa su caída y al barrenar el ruezno de nueces grandes afecta el desarrollo de la almendra y mancha los frutos, lo que reduce la calidad y rendimiento, e incrementa los costos de cosecha. Se exploró la abundancia y aspectos biológicos de Pterourus multicaudata en árboles de capulín (Prunus serotina Ehrn.) Las densidades de palomillas y porcentajes de nueces dañadas por el GBR en 2016 y 2017 fueron bajos en la huerta tratada con spinetoram (3.7 y 7.7 palomillas/trampa/semana, 2.0 y 5.0% de daño), intermedios en la huerta aplicada con benzoato de emamectina y methoxifenozide (10.0 y 23.0 palomillas/trampa/semana, 12.0 y 14.0% de daño), y altos en la huerta tratada con clorpirifos y cipermetrina (21.9 y 28.9 palomillas/trampa/semana, 15.0 y 34.0% de daño), así como en la huerta sin tratamiento (11.6 y 30.4 palomillas/trampa/semana, 39.0 y 63.0% de daño). Trachyderes (Dendrobias) mandibularis Dupont es reportado en diferentes estados de México asociado a frutales tropicales reportándose por primera vez su presencia en estado adulto alimentándose de frutos de guanábana (Annona muricata L.) en el estado de Nayarit, México. Vuill. The diversity of nocturnal hawk moths in a fragment of tropical semi-deciduous forest (TSDF) at central Veracruz, Mexico were described. The objective for the study was to test maize germplasm developed from Ecuador for resistance to leaf-feeding fall armyworm. Using standards set by the International Organization for Biological Control-West Palearctic Regional Section (IOBC-WPRS), most foliar-applied pesticides tested were “slightly harmful” or “moderately harmful” to A. colemani. Palabras clave: Argemone mexicana, Ricinus communis, daños, producción. However, permethrin, spinetoram + sulfoxaflor, dinotefuran, tolfenpyrad, and acetamiprid killed ≥70% of A. colemani. 0 En agosto de 2019, bajo un tronco en descomposición, se observó una hembra adulta (longitud 44 mm) enroscada sobre una masa de embriones (al menos 25 embriones en el segundo estadio; talla 3 mm). 0000006953 00000 n Densities on these varieties were 55-73% lower than on susceptible standard Bluebonnet 50. In addition, percentage of parasitism of green peach aphid, Myzus persicae Sulzer (Hemiptera: Aphididae), after plants were treated with five soil-applied systemic insecticides was determined in a greenhouse. The large grain borer, Prostephanus truncatus Horn, is a primary insect pest that reduces the quality and yield potential of stored cacahuacintle maize (Zea mays L.) in Mexico. 2891 32 Similar percentages of S. feltiae were found each year (∼20% of cores in S. feltiae + S. carpocapsae and S. feltiae + H. bacteriophora plots). Los índices entomológicos son una herramienta habitual utilizada para la vigilancia de vectores con importancia en salud pública, como Aedes aegypti. Aedes fulvus representa un nuevo registro para Tabasco, elevando el número de especies a 105. Average collection time between spraying and beating methods was reduced 48 and 67%, respectively. The damage can increase under stress in R. mangle, caused by environmental factor generating potential damage to tropical sentinel ecosystems that can eventually become irreversible. An experiment in a greenhouse confirmed that insect densities were lowest on Fedearroz 2000, Linea 34, and Altamira1N. Molecular analysis was done using the COI gene. Además, se capturaron los compuestos volátiles emitidos por las hembras durante el llamado y se identificaron tres compuestos: (Z)-9-acetato de tetradecenilo (Z9-14:OAc) como mayoritario, (Z)-11-acetato de hexadecenilo (Z11-16:OAc) como compuesto secundario y el (Z)-7-acetato de dodecenilo (Z7-12:OAc) como trazas en los tres grupos estudiados, por cromatografía de gases acoplado a espectrometría de masas (CG-EM). The fall armyworm, Spodoptera frugiperda (J.E. Persistent strains of entomopathogenic nematodes were released in May 2017 by the New Mexico State University Rex E. Kirksey Agricultural Science Center at Tucumcari into an irrigated alfalfa field not known to be infested with whitefringed beetle. Red spider mite preferred to colonize the lower leaf surface of the three piquin chilis and bean. T. vaporariorum had 96% similarity with 13 previous records of the same species. Lynxacarus radovskyiTenorio, 1974, is a mite that infests domestic and wild cats. While additional research is needed to further elucidate the spatiotemporal presence of L. clypealis in the region, the impetus for this report is to increase awareness of this invasive pest that might injure sorghum along the Texas Gulf Coast. In the laboratory, females survival was 60, 80, 80 and 93.33% on BGH-426, BGH-425, Ch and bean (Phaseolus vulgaris L.), respectively. Las especies colectadas fueron Aedes fulvus, Ae. Currently, 65 species, 71 genera, and 14 subfamilies of staphylinids have been identified and recorded from the state. Trichome averaged 6.5 per square centimeter in Nainari and 6.8 in the experimental line. 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. The clinical confirmation of the presence of the mite species in Mexico can impact differential diagnosis of feline dermatological diseases in Mexico, especially when clinical signs such as poor coat condition and alopecia are present on the sacrum area, perineum, tail, hind legs, and inguinal area. M. anisopliae had acceptable pathogenicity under field conditions, but M. acridum killed the most grasshoppers. The cat was remitted to the Veterinary Hospital of the Universidad Juarez Autonoma de Tabasco because it presented alopecia on the sacrum area and small yellowish white dots in its hair. Los insectos fueron criados en condiciones de laboratorio, dos grupos fueron alimentados con dieta artificial y uno con hojas de maíz.
