Doryctobracon crawfordi (Viereck) was recorded in the states of Amapá and Roraima, Brazil. This is also the first time that this parasitoid is associated with Anastrepha atrigona Hendel from Geissospermum argenteum

An update on vitamin d metabolism

Vitamin D is a steroid hormone classically involved in the calcium metabolism and bone homeostasis. Recently, new and interesting aspects of vitamin D metabolism has been elucidated, namely the special role of the skin, the metabolic control of liver hydroxylase CYP2R1, the specificity of 1α-hydroxylase in different tissues and cell types and the genomic, non-genomic and epigenomic effects of vitamin D receptor, which will be addressed in the present review. Moreover, in the last decades, several extraskeletal effects which can be attributed to vitamin D have been shown. These beneficial effects will be here summarized, focusing on the immune system and cardiovascular system

On the identity of Trichogramma demoraesi Nagaraja (Hymenoptera: Trichogrammatidae), with a checklist and a key to Trichogramma species associated with Erinnyis ello (L.) (Lepidoptera, Sphingidae) in Brazil.

Specimens collected from eggs of the cassava hornworm Erinnyis ello, originally identified as T. demoraesi, were compared with the paratype of this species. Based on morphological analysis, the specimens from E. ello actually belong to Trichogramma marandobai Brun, Moraes and Soares, 1986. Therefore, T. demoraesi is not a parasitoid of the eggs of E. ello, a major pest of cassava. The main features separating the two species, and a checklist and key to the species of Trichogramma associated with E. ello are presented.Autoria: QUERINO [i.e. SILVA], R. B. Q. da.
