Medicinal plants are an important source of bioactive compounds that have various biological effects on pests and diseases agricultural livestock importance. The present study evaluated the nematicidal insecticidal acetone extract (E-Ac) Prosopis laevigata leaves. tests were carried out under in vitro conditions. E-Ac had 100% activity against Haemonchus contortus at 40 20 mg/mL, while 10 mg/mL it nearly 60% mortality L3 H. larvae. When was incorporated into artificial diet, 88% effect...
Mine tailings contain high concentrations of heavy metals such as As, Pb, Cu, Mn, and Fe, which are detrimental to the health humans environment. In at El Fraile mine in Guerrero, Mexico, some plant species apparently tolerant can be found growing tailings. These plants could associating with metal-tolerant bacteria that promote growth improve biomass production, these a useful alternative for bacteria-assisted phytoremediation. The objective this study was isolate detected Fraile-Taxco,...
In this research, we evaluated the aphicidal effect of ethanolic extract stems and bark Ficus petiolaris Kunth (Moraceae), in laboratory bioassays an artificial diet against apterous adult females Melanaphis sacchari Zehntner (Hemiptera: Aphididae). The was at different concentrations (500, 1,000, 1,500, 2,000, 2,500 ppm), highest percentage mortality (82%) found ppm after 72 h. positive control imidacloprid (Confial®) 1% eliminated 100% aphids, negative (artificial diet) only presented 4%....
The sugarcane aphid, Melanaphis sacchari Zehntner (Hemiptera: Aphididae), is an important insect pest of sorghum and crops throughout the United States Mexico. In 2013, its capacity for crop destruction these 2 commodities amounted to millions dollars. Currently, no artificial diets are available that can be used in vitro screening potential bioactive substances toxic this aphid species. objective our work, reported herein, was evaluate liquid use such bioassays. We evaluated a diet...
Sugarcane aphid, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae), is now the main pest of sorghum, Sorghum bicolor (L.) Moench (Poaceae), in Mexico. Several ecologically friendlier alternatives were studied to control pest, including use pure commercial molecules. The objective study was evaluate insecticidal potential four molecules (squalene, xylitol, myristic acid, and quercetin) by fumigation vitro against apterous M. adults. Results showed that acid had strongest effect (79%)...
Plant extracts are a great source of molecules with insecticidal activity and used to control pests in various crop production systems. In this study, we evaluated the aphidicidal properties vitro n-hexane extract leaves castor-bean (Ricinus communis L.; Euphorbiaceae) at different concentrations (0.5, 1.0, 2.5, 5.0 10 kg m-3) against apterous adults corn leaf aphid (Rhopalosiphum maidis Fitch) yellow sugarcane (Sipha flava Forbes). The observed effects were dose-dependent, highest...
The sugarcane aphid, Melanaphis sorghi Theobald, 1904 (Hemiptera: Aphididae), is the most important pest of Sorghum bicolor (L.) Moench (Poaceae), in Mexico. Control M. depends primarily on synthetic chemical insecticides, but new alternatives have been explored, such as botanical insecticides. objective this research was to evaluate aphidicide effect extract nhexane and methanol from stems Ceiba aesculifolia (Malvaceae) against apterous adults vitro. results revealed that n-hexane C. killed...
The mining activity has left mine tailings with high quantities of heavy metals and metalloids. Due their extreme toxicity, they represent a hostile environment for microbial colonization; however, there are metalotolerant bacteria in these wastes, this is attributed to mechanisms bioaccumulation biotransformation metals. native from El Fraile have developed adaptation that allow them persist toxic environment, thus, the objective study was isolate identify ability tolerate, bioaccumulate or...
Petroleum derivates used in energy production are gravely pollutants for the ecosystem, especially aquatic environments and human health. This study aimed to isolate hydrocarbons-degrading bacteria from hot springs. Three strains of hydrocarbondegrading strains, belonging Bacillus one genus Lysinibacillus were isolated. These tolerate temperatures 65 100 ºC able degrade grow on BH medium supplemented with gasoline diesel. Strain M2-7 shared % 16S rRNA identity licheniformis was only pyrene...
The State of Guerrero is characterized by various agroecological niches in which different agave species are produced naturally for production mezcal. Currently, mezcal agaves have become economically important to farmers who produce them. Agave affected problems such as pests and diseases that reduce pineapples angustifolia Haw. decrease the quality At Guerrero, plots at Municipallity Huitzuco de los Figueroa, Teloloapan, Tixtla Zitlala; Puebla, Municipality Acatlán Osorio, Xayacatlán Bravo...
Aethina tumida es una plaga de África, y se ha convertido en amenaza emergente para la salud las colmenas abejas fuera su área endémica. En el 2007, reportó por primera vez México estado norteño Coahuila. Posteriormente, sería confirmada presencia varios estados México. enero del 2023, un apiario municipio Iguala Guerrero, inspección rutina realizada apicultores reveló adultos A. Apis mellifera. Este primer reporte llegada al Guerrero. La incontrolable propagación a través regiones apícolas...
El gorgojo del maíz, Sitophilus zeamais Motschulsky, es una de las plagas postcosecha más comunes y destructivas mundo, que daña cereales almacenados. Se han estudiado varias alternativas ecológicas para controlar a S. , incluido el uso extractos plantas. objetivo estudio fue utilizar pruebas fitoquímicas cualitativas evaluar efecto insecticida extracto acetónico hojas Dysphania ambrosioides contra adultos en maíz nativo Ratón. utilizaron siete tratamientos concentraciones 10, 50, 100, 200...
In Mexico, manzano pepper (Capsicum pubescens) is a crop of economic importance. 2022, in the municipality Taxco de Alarcon, Guerrero, leaf spots were observed mazano crop. The fungus Alternaria spp., was consistently isolated from symptomatic pepper. A molecular characterization carried out by amplification and sequencing internal transcribed spacer (ITS) region ribosomal DNA, major allergen (Alt 1), anonymous gene (OPA10-2). BLAST analysis indicated similarity that varied 99.5 to 100% with...
Roselle (Hibiscus sabdariffa L.) is a crop of economic importance, refreshing drinks are prepared from its calyces, it also attributed to antioxidant, antibacterial, and antihypertensive properties (Da-Costa-Rocha et al. 2014). In November 2022, in municipality Iguala (18.355592N, 99.548546W, 749 m above sea level), Guerrero, México, roselle plants approximately 1.5 months age with basal rot were detected under greenhouse conditions. The symptoms consisted wilting, yellowing, root stem...
