| El objetivo de este estudio fue evaluar el efecto de suplementar con nopal fresco y deshidratado, en la respuesta productiva y calidad de la carne de corderos. Se dividió en dos etapas. La primera en la evaluación del comportamiento productivo, y la segunda, la evaluación de la calidad de la carne. Se utilizaron 27 corderos machos de cruzas comerciales, con peso inicial promedio de 21.4kg, distribuidos homogéneamente en tres grupos de 9 animales, y sacrificados a peso promedio de 37 kg. Los grupos fueron asignados al azar a cada uno de los siguientes tratamientos: (T1) dieta testigo, (T2) dieta con 17 % (base seca) de nopal deshidratado, y (T3) dieta con 17 % (base seca) de nopal fresco. En la primera etapa, se evaluó la digestibilidad in situ de la... |

| En las zonas semisecas, es necesario buscar alternativas de producción agrícola para el mejor aprovechamiento del suelo, por ello, el objetivo fue evaluar el crecimiento de cuatro variedades de Opuntia ficus-indica (L.) Mill nopal de tuna verde (ntv), nopal de verdura (ndv), nopal de tuna roja (ntr) y nopal de tuna sin semilla (ntss), así como las especies columnares Stenocereus stellatus (Pfeiffer) Riccobono, S. griseus (Haworth) Buxbaum y epifita Hylocereus undatus (Haw) Br & R variedades Nunila, Chiapas, Xalapa y Acanthocereus pentagonus (L.) Britt & Rose respectivamente. El experimento se realizó en Angostillo, utilizando un diseño en bloques al azar, con cinco repeticiones, con diez tratamientos, con unidad experimental de cinco plantas... |

| The distribution pattern of species of the genus Dactylopius Costa in Mexico was analyzed in relation to the distribution of their host plants (subfamily Opuntioideae) to evaluate the specificity of the insect-host association. The distribution of Dactylopius currently recognized is narrower than that of its hosts and probably is not representative. Therefore, a broader distribution of the Dactylopius species in correspondence with those of their hosts was hypothesized. Insects and their hosts were collected and georeferenced in 14 states of Mexico from 2005 to 2007. The distribution areas, maps, and habitat characteristics of Dactylopius, Opuntia sensu stricto, Nopalea and Cylindropuntia were determined on the basis of field collections and examination of... |

| ABSTRACT The knowledge on soil water dynamics is the basis of crop water management. The soil water balance (SWB) method is used for this purpose. However, its application in cactus may lead to misinterpretation in water efficiency analysis, since it does not consider the amount of water retained in the plant (WRP). This study aimed to evaluate SWB applicability, hydrodynamic changes and water efficiency of forage cactus clones under irrigation. The clones ‘Orelha de Elefante Mexicana’ (OEM), ‘IPA Sertânia’ (IPA) and ‘Miúda’ (MIU) were submitted to irrigation depths (2.5, 5.0 and 7.5 mm) and frequencies (7, 14 and 28 days), in Serra Talhada, PE, Brazil, between March 2012 and August 2013. The SWB was applied, by adding the WRP in the estimate of the... |

| Studies on the survival of species are essential to understanding their biology and to developing effective conservation and management plans. This study aimed to determine the best model to explain the survival of the species Melocactus conoideus on the basis of time, density, age structure and habitat location, as well as to describe the interactions among those factors. The study was conducted in three M. conoideus habitat patches in the municipality of Vitória da Conquista, in the state of Bahia, Brazil, only one of which was within a "conservation unit" (protected area). In each patch, we selected 120 specimens of M. conoideus, which were marked with identification plates and classified by developmental stage and density. The survival of those... |

| The purpose of this study was to evaluate the chemical, physiological and genetic differences in seeds of cactus of the Cereus genus (mandacaru) cultivated in the Northeast (Picos, State of Piauí) and Southern (Maringá, State of Paraná) regions of Brazil. Over a period of eight days, temperatures of 25°C and 30°C were equally efficient for the germination of all the seeds. Oleic acid (C18:1) was the most common fatty acid found in the seeds collected in the Southern (41%) and Northeast (45.5%) regions. The analysis of lipases indicated that seeds from Maringá have high mean observed and expected heterozygosities and that seeds from Picos have a higher number of alleles per loci. Therefore, the seeds of mandacaru from the semiarid region of Northeast as... |

| Representative strains of Serratia marcescens from an edible cactus plant and silkworms were characterized and a comparison based on their cellular fatty acid composition, 16S rRNA and groE gene sequence analysis as well as silkworm virulence and chitosan susceptibility was carried out. Results from this study indicate that there are no significant differences between the phenotypic and molecular characterization, virulence and chitosan susceptibility of the S. marcescens strains from the cactus plant and silkworms. Silkworms inoculated with S. marcescens from either plant or silkworm resulted in nearly 100% mortality. Chitosan solution exhibited strong antibacterial activity against S. marcescens. This activity increased with the increase of chitosan... |
