Enjoy the Saint Joseph Cathedral Gallery. These bees depend almost exclusively on squash flowers for pollen and nectar for themselves and their larvae, and therefore appear to have coevolved with the cucurbits.
The center of diversity of these bees occurs in southern Mexico, where the greatest concentration of Cucurbita species is located. There is one species of squash bee, P. There are other more generalized species of squash and gourd bees, which occur throughout the Americas and use the pollen of all the cultivated species of squash, including C.
The absence of P. This is based on the assumption that P. Before reaching a definitive conclusion about human dispersal of C. Peponapis atrata may not be as monolectic as reported in the literature; a female P. Andres and species determined by W.
The hypothesis resulting from the squash and gourd bee study of Hurd et al. While they are derived from extensive field observations, they have not been tested experimentally. The study did not demonstrate whether the various species of bees coevolved with specific species of Cucurbita or with the genus in general. The latter is the rule among oligolectic bees G.
The fact that these bees and Cucurbita species share centers of diversity may not be due to their coevolution but rather to other causes such as their independent adaptation to the extreme habitat diversity of the region. Experimental tests need to be conducted to determine if species such as P. There are also few consistent morphological differences in the flowers of Cucurbita species. For example, the ultraviolet patterns, i.
Whether the bees are able to cue in on other interspecific differences in the cucurbit flowers has yet to be determined. This conclusion is based on compatibility data and the distribution of the possible wild progenitors. Cucurbita ficifolia and C. Evidence from comparative morphology, geographic distribution, ecology, and genetic relationships do not, however, indicate a very close relationship between these wild species and C.
Cucurbita lundelliana is the only wild mesophytic cucurbit that has been reported to cross with C. Furthermore, pollen fertility was reported to be higher in the F 1 hybrids between C. Neither wild species occurs in the cool highland areas where C.
These two species are closely related and both have small gray colored green when wet seeds that bear little resemblance to those of C. A recent extensive crossing program showed that when C. Sterility barriers prevented obtaining subsequent generations.
These two xerophytic species and C. In the study on the relationships of Cucurbita species with the squash and gourd bees Hurd et al. In South America there are less likely candidates for the wild progenitor of C. Only two wild species of Cucurbita are endemic to South America. There is perhaps more persuasive evidence suggesting that C. Intensive searches for a compatible wild progenitor of C.
Although less intensive searches have been conducted south of Mexico, there are sketchy reports of possible wild or at least spontaneous populations. This shape has not been found elsewhere and, if this report is correct, may represent a primitive character or a derived morph from an ancestral population. No description or documentation is provided on the morphology of the plants.
The hypothesis of an Andean origin and domestication of C. Cucurbita ficifolia is most likely uniquely adapted to cool, moist conditions because it evolved in a habitat characterized by such a climate.
The preponderance of short-day flowering accesions points to an area of origin within the torrid zone. If domestication occurred in the northern Andes around or before B. A similar situation occurred in C. However, in the case of C. Other examples of New World crops involved in very early long distance cultural exchanges include peanuts and guava, which spread from Peru to Mexico by B. It is conceivable that there are still extant wild conspecific populations of C.
Furthermore, in such an area this species may contain greater genetic diversity than has been found elsewhere. Germplasm collecting and evaluations need to be conducted in this region.
There are few dry caves in this region where archaeological preservation could have occurred, but those fruits that were traded with cultures along the dry Peruvian coast may have been preserved. This type of trading of the highland grown C.
However, the name C. In addition to C. In the late 's C. There is nothing in the description to indicate this name to be anything but a synonym of C. Two species have been incorrectly ranked as varieties or cultivars of C.
