| Abstract: | Field observations on the biology ofMetriona elatior (Col.: Chrysomelidae) onSolanum elaeagnifolium (Solanaceae) from Uruguay.
Specimens ofMetriona elatior were found feeding on leaves of the silverleaf nightshade,Solanum elaeagnifolium, from the eastern of Uruguay since 1984. According to a field study the young leaves were skeletonized since spring to early
autumn by larvae and adults. Oothecae and pupae were found mainly on old leaves. The egg mean volume was of 0.614 mm3. Young plants of the weed were always killed after massive natural infections ofM. elatior. Therefore, this tortoise leaf-beetle may be studied as a potential biocontrol agent on populations ofS. elaeagnifolium.
