“…is one of the richest genera in the family Cactaceae, with 200 to 250 species in consistent with different authors (Britton & Rose, 1919;Anderson, 2001;Rebman & Pinkava, 2001). Under natural conditions representatives of the genus are known from the American continent (Mahr, 2001;Nyffeler, 2002;Bulot, 2007;Majure & Ervin, 2008).…”

“…Due to numerous xeromorphic adaptations most species are confined to arid habitats of subtropical and tropical natural belts. Mexico is a centre of the genus' diversity (Mahr, 2001;Rebman & Pinkava, 2001;Casas & Barbera, 2002;Majure & Ervin, 2008). Some Opuntia species are able to withstand temperatures below freezing during the winter period (Loik & Nobel, 1993;Nobel & Bobich, 2002).…”

The results of a study of Opuntia humifusa and O. phaeacantha naturalised in the Karadag Nature Reserve (southeastern part of the Crimean Peninsula) are presented. There, the largest coenopopulations of Opuntia plants are confined to the «biostation» territory (bordering with the park, administrative buildings and housing estate). Twelve localities were described in the Karadag Reserve. These differ by phytocoenotic characteristics, area and floristic composition. Seven localities include only O. humifusa plants; four ones include only O. phaeacantha individuals; and both the species are present on the twelfth locality. The total number of individuals of each species and ontogenetic structure of the population were studied in each locality. The total number of O. humifusa individuals in the Karadag Reserve is more than 600 plants within the «biostation» territory, while the total number of O. phaeacantha plants is about 400 individuals. Studying of the plant communities has been carried out according to the Braun-Blanquet method. Opuntia plants form derivate communities within degraded steppes, phryganoid-steppes, and semi-desert badland phytocoenoses almost at all studied localities. A significant number of synanthropic species (including alien plants) was found within these communities. Opuntia plants are able to self-reproduce predominantly vegetatively. Self-seeding reproduction occurs less frequently. Both species can be considered as invasive plants because they have a high adaptive capacity.

“…The rapid spread of this invasive moth (Hight et al 2002) is not only a threat to rare endemic cacti (Rebman and Pinkava 2001, Stiling and Moon 2001, Hight et al 2002, native desert ecosystems (Mahr 2001), and the ornamental prickly pear industry in the United States (Irish 2001), but it could have catastrophic effects on the Opuntia industry in Mexico, where prickly pear cacti are being used extensively as human food and livestock fodder (Zimmermann et al 2004).…”

Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae) is an invasive herbivore that poses a serious risk to Opuntia cacti in North America. Knowledge of the ßight behavior of the cactus moth is crucial for a better understanding of natural dispersal, and for both monitoring and control. We used computer-linked ßight mills to investigate diel ßight activity and ßight performance in relation to gender, age, mating status, and body size. Maximal ßight activity for both mated and unmated moths occurred during twilight, whereas ßight activity was low during photophase. The total distance ßown and the number of initiated ßights within a diel cycle were higher in both unmated and mated females than in males, but the longest single ßight was similar in both genders. These Þndings suggest that pheromone trap captures of males likely indicate the simultaneous presence of females and that mated females might even be in areas where males are not detected yet. Flight performance heterogeneity was large, with a small portion of the population (both males and females) performing long unbroken ßights, whereas the majority made short ßights. Females had higher pupal and adult body size and shorter longevity than males. A few individuals, particularly young mated females, ßying long distances may be important for active spread of a population and the colonization of new habitats. Implications of this study in the control of the cactus moth by using the sterile insect technique are discussed.

“…Algunos autores (Rebman & Pinkava, 2001) mencionan que la variabilidad morfológica en especies de Opuntia está influenciada por presiones ambientales. Por ejemplo, Benson (1982) , debida a cambios en la densidad poblacional; destacan las variables: profundidad de la cripta estomá-tica, grosor de cutícula, altura del tallo, número de espinas adpresas por aréola, número de espinas por aréola de menos de 1 cm, grosor del parénquima, grosor del cladodio, grosor de la epidermis, número de líneas de aréolas por cara del cladodio, entre otros.…”

The aim of this study was to describe morphological variations of Opuntia jaliscana in 5 wild populations in the state of Jalisco (Mexico). Populations were selected along an environmental aridity gradient, and 61 vegetative and reproductive characters from 25 individuals were measured per population. Quantitative characters were analyzed independently by a one-way ANOVA test using the site as variation factor. Subsequently, a discriminant analysis was performed. The discriminant analysis results showed that the 46% of the total variation was explained by the first four discriminant functions. The analysis of overall membership between populations indicated that individuals were correctly classified in 87% of cases. Pearson linear correlation between the most significant variables and the aridity index, showed a positive relationship to cladode thickness and diameter of the trunk. The population from Tierra Blanca shows an outlier behavior because of variation in cladode thickness and fruit size, which might be related to plasticity of individuals to have a greater availability of water, while in Los Vallejo the separation might be due to selection by management and use. The remaining populations exhibited some morphological variability without separation.
