Objective: to determine the presence of Bruggmanniella perseae in commercial Hass avocado orchards Teteladel Volcán, Morelos (Mexico).Design/Methodology/Approach: sampling was carried out three during October-December 2020. Adults B. were collected by direct collections small fruits form a spinningtop, with symptoms infestation inside. The adults thus observed under stereomicroscope and scanning electron microscope confirm their identity.Results: adult specimens captured analyzed laboratory...
El picudo del agave, Scyphophorus acupunctatus (Coleoptera: Curculionidae), se maneja con trampeos feromona sintética y cebo alimenticio. Se evaluaron trampas comerciales de diferentes colores manufactura artesanal. No hubo diferencias significativas entre las capturas en artesanales comerciales, pero si los últimas, siendo rojas naranjas donde mayor captura picudos agave. Esto sirve para tener mayores agave solo la selección trampa, además no ser necesaria una trampa comercial. La...
Mango (Mangifera indica L.) is an intensively cultivated fruit in Mexico, the leading exporter of this product world. One important limiting factor mango production white scale (Aulacaspis tubercularis Newstead; Hemiptera: Diaspididae). White infestation causes irreversible leaf yellowing and death, it lowers quality below export requirements. Feeding mechanisms these diaspidids have not been extensively studied; no histological studies on subject are known. We histologically analyzed...
The present research was aimed at the foliar biofortification of chard plants with iron and selenium determining influence this treatment on accumulation these elements, as well proteins nitrate, in aerial portion (shoot) chard.A 3 2 factorial experiment conducted for above purpose, study factors were applications Fe (0, 2500 5000 mg L -1 ) Se 10 20 ).The performed every 15 days a total four spray applications.The variables evaluated accumulations Fe, Se, proteins, nitrate shoot.Two samples...
Productores agrícolas en México recientemente notaron un fuerte incremento las infestaciones de ácaros huertas papayo (Carica papaya L. 1753). Se elaboró una lista especies asociados con hojas para determinar responsables altas y identificar a los depredadores. Los fueron colectados tres estratos (alto, medio bajo) siete muncipios del centro estado Veracruz. Las procesadas por lavado tamizado. identificadas incluyeron cuatro tetraníquidos: Eotetranychus lewisi (McGregor 1943), Eutetranychus...
Abstract: The objective of this work was to evaluate phytosanitary strategies for the chemical control powdery mildew (Oidium mangiferae) in mango, based on alternation active ingredients with different modes and sites action, determine environmental epidemiological conditions that favor development disease. experiment conducted Guerrero, México, commercial orchards, within a program fungicide spraying strategies. Epidemic curves were used temporal analyses disease for: incidence; area under...
The aim of this study was to determine the nutritional composition Acacia farnesiana, macilenta and cochliacantha fruits intake (FI) relative palatability index (PI) its correlation with fruit in sheep goats.Sixteen females goats were used: eight (F1 Dorper X Pelibuey body weight 18.5 ± 1.5 kg) Creole (body 20.6 1.8 kg).Animals housed individual pens (1.0 1.20 m) fed on (ad libitum) three acacias corn stover (CS) for 24 hours during 15 days experiment.Neutral acid detergent fiber content,...
Corn (Zea mays) is the most consumed cereal in México, so it necessary to know nutritional and anatomical quality of grains, which have been main conservation consumption criteria prehispanic peoples. This practice has allowed preserve varieties Creole corn, however, due lack knowledge these characteristics cultivation maize reduced, presenting a high risk disappearing. The objective was determine physical, nutritive functional four creole corn: Purple-Olotillo, Dos-Puntas, Toro Olotillo....
Los Agaves son nativos de América y tienen diferentes usos, entre los que destacan la obtención fibras elaboración bebidas alcohólicas; esto ha ocasionado una considerable disminución en las poblaciones silvestres; por lo que, el objetivo fue caracterizar morfológicamente cápsulas semillas, evaluar desarrollo plántula maguey sacatoro (Agave angustifolia Haw.) colectadas sitios del centro norte estado Guerrero, México, para su propagación semilla. Para análisis morfométrico se empleó un diseño...
Bacillus thuringiensis is an entomopathogenic bacterium that produces crystal-proteins with cytotoxic activity against insects and nematodes. B. toxicity on agriculture pests widely recognized, however, there little information about the lethal action of Recently, nematicide proteins was showed Haemonchus, Teladorsagia, Nippostrongylus, Ancylostoma genera mammals, plant parasitic nematodes, Globodera Meloidogyne. From a list strains effect, selected from IB-16 isolate 50 to 100 % nematocidal...
El objetivo de la investigación que se deriva este artículo fue documentar el conocimiento tradicional los productores maguey y mezcal del estado Guerrero en México: sus prácticas agronómicas, aspectos ecológicos imbricados éstas, así como usos, costumbres, tradiciones las alternativas han instrumentado para rescatar preservar tradicional; ello con fin explorar posibilidades articulación aportes científica. estudio realizó región Centro (cinco localidades dos municipios) Norte (tres entre...
The objective was to evaluate the activity against Haemonchus contortus by foliage taken from three tanniferous tree species and fed Creole male kids experimentally infected with a dose of 350 larvae H. (L3) kg -1 body weight (BW). Twenty weighing 12 ± 2.0 were randomly distributed in four treatments: T1 = control without foliage, addition fresh (10 % dry matter total diet) Guazuma ulmifolia (T2), Pithecellobium dulce (T3) Acacia cochliacantha (T4). For sixty days, evaluated quantifying...
Se realizaron analisis fisico-quimicos y microbiologicos durante la temporada de secas lluvias para cono-cer calidad del agua cuenca baja rio Papagayo sus a uentes. Los parametros analizados se compararon con los criterios ecologicos las Normas Oficiales Mexicanas.

Forty-eight epidemic outbreaks of the papaya ringspot potyvirus (PRSV-p) in cv. Maradol Roja Paso de Ovejas, Veracruz, Mexico, were analyzed, under different plant densities, application 2.5 % neem aqueous extract, and roguing plants with initial symptoms PRSV-p. The logistic model had best fit to 47 curves. Analysis variance incidence severity data based on “area curve disease progress” “adjusted rate for Rho” variables, resulted highly significant differences (P£0.0009) variables density...
Objective: The objective was to evaluate the morphological characteristics of okra fruit[Abelmoschus esculentus (L.) Moench.], an endemic crop Afro-Mexican region, inthe dry tropics.Design/Methodology/Approach: Materials were collected in Cuajinicuilapa, thestate Guerrero Mexico. Using a completely randomized design (CRD), 4 repetitionsof 100 fruits selected, and each evaluated for following: weight, number,size shape seeds.

Mites are considered the second pest in importance papaya (Carica L.) Veracruz, Mexico, caused by a general increment pesticide use that might unbalance predatory populations. Efficacy of acaricides was evaluated against phytophagous mites, and their selectivity to predators cv. Maradol. A completely randomized block design with nine treatments four replications used. Significant differences (P = 0.005) were found number mites alive per leaf after third weekly application. The lowest...
