Zoology

Research on the Chrysomelidae (Coleoptern) family from the upper basin of the Mures River _______________with special reference on its nutritional characteristics_______________

Fig. 2: Distribution of monophagous chrysomelide species on subfamilies

The oligophagous species, the most numerous ones, have nine subfamilies, thus except for the Donaciinae all subfamilies are represented with variable number of species. The best represented subfamilies are the Halticinae with 66 species, followed by the Chrysomelinae subfamily with 32 species, as well as the Cassidi пае with 8 species, the Cryptocephalinae with 7 species, the Galerucinae and Criocerinae with 3 species, the Clythrinae with 2 species and the Lamprosomatinae and Zeugophorinae with one species each (Fig. 3).

Fig. 3: Distribution of the oligofagous Chrysomelide species on subfamilies

The polyphagous species fall within all the ten subfamilies revealed by the research. The best represented subfamilies are the Halticinae with 25 species, followed by the Cryptocephalinae with 17 species, the Chrysomelinae with 13 species, the Clythrinae with 9 species, the Cassidinae with 7 species, the Galerucinae with 6 species and the Donaciinae, Zeugophorinae, Criocerinae and Lamprosomatinae with one species each (Fig. 4).

Conclusions

The species of the ten subfamilies present within the researched area are predominantly oligophagous, most preferring plants from the same family, followed by the polyphagous species, consuming plants from two or more families and the monophagous species preferring a single host plant.
