	abstract = {The larval development of Canthon cyanellus cyanellus LeConte was analyzed upon 92 larvae of known age. Larval stage lasted nine days and consists of three instars; each one with a particular length of time and specific cephalic-width range. Most of the anatomical larval features appear since the first instar and they strengthen in the following two. The comparison of several anatomical features among larvae of Canthon cyanellus cyanellus, C. pilularius Linnaeus, C. humectus humectus Say and C. edentulus Harold showed that C. cyanellus cyanellus and C. pilularius, shared the most numerous characters in common wich could indicate that these species are taxonomically close. },

	abstract = {A well defined sexual dimorphism is present in scarabaeoid larvae. Dimorphism was observed in late-age larvae of some species of Scarabaeidae, Aphodiidae, Trogidae, Orphinidae, Dynastidae, Passalidae and Lucanidae. This dimorphism manifests itself in the presence of a terminal ampulla, a cuticular structure situated in the ventral region of the 9th abdominal segment which is only present in male specimens. In Scarabaeidae, sexual dimorphism was only observed in the pupae of six species. The terminal ampulla in Canthon cyanellus cyanellus LeConte (Scarabaeidae) is present in the male larvae apparently since the first instar, and changes morphologically during the next larva instars. Only a detailed study of the morphogenesis of the terminal ampulla during the larval and pupal stages could help to define exactly what structures of the ejaculatory bulb and aedeagus it will turn into in the adult stage.},

	abstract = {This paper addresses the association between use of a herbicide and anecdotal reports of reduced dung degradation and dung beetle populations. Dung beetles were monthly collected at two adjacent ranches in Mexico. Ranches were similar in area, elevation, exposition, soil, and vegetation, but differed in weed control. Ranch A controlled weeds manually, and ranch B controlled unwanted vegetation with applications of the herbicide Tordon(R)101M. The main species recovered on each ranch (Ataenius apicalis) was significantly more abundant at ranch A than at ranch B. Conversely, similar numbers of a second species, Ataenius sculptor, were recovered from both ranches. Three lines of evidence support the tentative conclusion that herbicide applications may be causing a decline in populations of A. apicalis on ranch B. First, the greatest reductions of A. apicalis were observed during periods of herbicide application. Second, A. sculptor, apparently little affected by these same herbicide applications, is active primarily during months without herbicide applications. Third, preliminary results of laboratory studies show that exposure to herbicide can impair reproductive function of the dung beetle Canthon cyanellus.
