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. on Sphenarium purpurascens in Central Mexico. The grasshopper Sphenarium purpurascens (Charpentier) (Orthoptera: Pyrgomorphidae) is one of the most important pests of crops in Mexico. 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. All small-sized insects were males, the medium-size category had 60% females and 40% males, and the large-size category was 100% female. Aphidius colemani Viereck (Hymenoptera: Braconidae), an endoparasitoid of green peach aphid, Myzus persicae Sulzer (Hemiptera: Aphididae), and other aphid pests, killed after exposure for 6, 12, 24, and 48 hours to 13 contact insecticides and two fungicides at medium and high rates were assessed in a laboratory. The first two were collected on avocado trees, and the third was found in weeds associated with an avocado orchard. Monitoring is a key activity in management of pests such as phytophagous thrips (Thysanoptera). All germplasms tested are tropical populations that require breeding to enable more research in temperate regions. 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. Los cicadélidos (Cicadellidae) se encuentran entre las plagas que afectan el cultivo de arándano (Vaccinium spp.) No hubo correlación entre la densidad poblacional y los aspectos climáticos analizados, pero se observó una tendencia a una mayor densidad en los meses más cálidos y secos. The results showed that R. mangle propagules could maintain colonization dynamics in insects of different orders, consuming tissue that jeopardized the survival and establishment of propagules. In addition, the systemic insecticides cyantraniliprole, dinotefuran, flupyradifurone, imidacloprid, spirotetramat killed 100% of green peach aphids, thereby eliminating hosts for A. colemani to parasitize. GEMN-0048 was not resistant but variability was observed in 14-day scores between 4 (resistant) and 8 (susceptible) in individual plants. 0000005788 00000 n Entomopathogenic nematodes (Steinernema carpocapsae Weiser, Steinernema feltiae Filipjev, and Heterorhabditis bacteriophora Poinar) effectively control other species that inflict similar damage to alfalfa and other crops, but it is not known if they occur naturally or can persist if released in irrigated semiarid lands. Please select when you would like to receive an alert. in Oklahoma. Correlation analysis did not indicate a relationship between environmental variables and richness or abundance of hawk moths. Peltophorus polymitus (Boheman 1845) has been historically registered as pest at three municipalities in the State of Durango. The λ ranged from 1.47 on Ch to 1.84 on bean. To promote development of a sustainable management program, eight Nicaraguan rice varieties were evaluated in greenhouse and field experiments for resistance to the pest. Data from museum collections of Z. tetracanthus suggested the insect has a univoltine life cycle. Once discovered and characterized, native sources of maize resistance to this pest could be effectively integrated with existing control tactics. <]/Prev 342703/XRefStm 1570>> 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). 0000009360 00000 n The native strain with most pathogenicity was compared with the commercial strain in the field. M. anisopliae had acceptable pathogenicity under field conditions, but M. acridum killed the most grasshoppers. Los resultados muestran que el ciclo biológico fue diferente en los tres grupos, los criados con dieta artificial tardaron 57.6 y 58.9 días en completar el ciclo, y los criados con hojas de maíz 66.9 días. However, other damage characteristics such as perforation size and gallery volume were significantly related to insect presence. ; siendo más abundante A. epinotiae (66.6%). The fall armyworm, Spodoptera frugiperda (J.E. en el mundo. For P. minei, there was 98% similarity with a record for the subfamily Aleurodicinae and 82% with the species Paraleyrodes bondari. Entomopathogenic fungi used as biological control agents in different agroecosystems are natural enemies of the insect. A comprehensive summary of associated host plants is also presented, describing 44 plant associations in 20 plant families for L. clypealis. Se actualiza la riqueza de especies de mosquitos en el estado de Durango, México, obtenida en 28 localidades. Natalia Morales-Martínez1, Erica Mariana Hernández-Hernández2, Samuel Ramírez-Alarcón3, Juan Fernando Solís- Aguilar3.1,3Departamento de Parasitología Agrícola de la … Digital images of 103 P. truncatus adults were processed, and the body length, abdomen length, abdomen width, and distance between clypeal tubercles were recorded from least to greatest according to the distance between clypeal tubercles. … The insect pest was discovered in rice in the southern U.S. on multiple occasions, most recently in 2015 and 2018. 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. Se obtuvieron 6,236 especímenes que representan a ocho subfamilias, 21 tribus, 45 géneros, y 40 especies de Cicadellidae. La fracción F3 obtenida de un extracto metanólico de D. viscosa (DvEM), exhibió una actividad afidicida del 70% frente a M. sacchari en una concentración de 10,000 ppm a las 72 horas en dieta artificial. trailer However, little is known of the biology or ecology of P. polymitus, a potential pest of the agave crop. En subfamilias Deltocephalinae y Cicadellinae se concentró el mayor número de especies. Lynxacarus radovskyiTenorio, 1974, is a mite that infests domestic and wild cats. We report the occurrence of an invasive hemipteran pest species along the Texas Gulf Coast. We report the third known locality for a rare booklouse, Speleketor flockiGurney 1943, not collected in more than 35 years. This new record expands the range of the entire genus significantly north and into colder environments at higher elevation. Presenta dimorfismo sexual, siendo la hembra de mayor tamaño con una coloración verde de patrón uniforme.El macho puede presentar coloraciones verdes o cafes con manchas oscuras. Similar numbers of thrips were collected with conventional methods and the new collecting device. Se describe una nueva especie de mosca blanca Aleuropleurocelus eriogonum Carapia-Ruiz sp. Insect densities in the field were measured using a battery-powered vacuum sampler during as many as five sample dates before and after flooding. The objective of this research was to evaluate the effectiveness of Beauveria bassiana (Bals.-Criv.) Las especies colectadas fueron Aedes fulvus, Ae. El objetivo principal de este estudio fue identificar el compuesto mayoritario de una fracción (F3) de hojas de Dodonaea viscosa con actividad afidicida contra Melanaphis sacchari. The diversity of nocturnal hawk moths in a fragment of tropical semi-deciduous forest (TSDF) at central Veracruz, Mexico were described. Este último índice entomológico fue más sensible a factores como el saneamiento de las casas, inducido por las evaluaciones entomológicas. Brahea berlandieri es una palma endémica del noreste de México catalogada como especie sujeta a protección especial. 0000007357 00000 n In plants infested with whitefly eggs and nymphs, eight compounds were identified in Nainari and seven in the experimental line: M-xylene; 1-octen-3-ol; d-limonene; cedrene; propanoic acid, 2-methyl-, 2-methyl propyl ester; 3-methylnonane; longifolene; caryophyllene; 2,5-cyclohexadiene-1,4-dione, 2,6-bis (1,1-dimethylethyl)-; alpha-farnesene; pentanoic acid, 2,2,4-trimethyl-3-carboxyisopropyl, isobutyl ester, and 2,6-bis(1,1-dimethylethyl)-4-(1-oxopropyl) phenol. and its effect on intestinal proteolytic activity of adult Orthoptera Schistocerca piceifrons piceifrons (Walker) and Pterophylla beltrani (Bolívar and Bolívar) were studied. Preference for oviposition by whitefly in two soybean genotypes was evaluated, and a profile of volatile compounds in healthy plants was obtained. 0000098388 00000 n Early stand decrease in alfalfa (Medicago sativa L.) throughout New Mexico is increasingly being attributed to root systems damaged by larvae of whitefringed beetle, Naupactus leucoloma Dejean. Vuill. Preference for the lower or upper leaf surface was evaluated. Piquin chili, Capsicum annuum var. The mean times for development of the five instars were 6.96 ± 0.13, 5.18 ± 0.13, 6.94 ± 0.29, 10.92 ± 0.43, and 17.93 ± 0.76 days, respectively. 0000006065 00000 n aegypti, Ae. We can help you reset your password using the email address linked to your BioOne Complete account. Individual-based rarefaction curves and sample coverage showed satisfactory hawk moth community. A 250-watt mercury-vapor lamp was used nocturnally for collection each month for 1 year. Twenty soil cores were collected per plot in autumn 2017 and 2018 to bioassay for establishment of entomopathogenic nematodes. Control de Sphenarium purpurascens con Beauveria bassiana y extractos vegetales en amaranto (Amaranthus hypocondriacus L.) 237 los 2 000 msnm como Chihuahua, Durango, San Luis Potosí, Hidalgo, Estado de México, Michoacán, Puebla, Tlaxcala y Guanajuato (García y Lozano 2011). El 3-O-rutinósido de quercetina (rutina) fue aislado de F3 por técnicas cromatográficas convencionales e identificado por resonancia magnética nuclear y análisis de cromatografía liquida de alta resolución (HPLC). The three accessions of piquin chili were most resistant to T. merganser. stigmaticus. 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. 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).
