période de cohabitation dans les greniers après les récoltes du niébé. Abstract : With an automatic image analysis device, we studied the temporal distribution of the locomotor activity of E orientalis and E vuilleti during 24 hours, and over several days to know whether the activity rhythms of these two Eupelmidae play a role in their competitive interactions. The analysis of locomotor activit...

Three pandemics have been attributed to plague in the last 1,500 years. Yersinia pestis caused the third, and its DNA was found in human remains from the second. The Antiqua biovar of Y. pestis may have caused the first pandemic; the other two biovars, Medievalis and Orientalis, may have caused the second and third pandemics, respectively. To test this hypothesis, we designed an original genoty...

Vegetation phenology, as used and studied the related studies, refers to the relationship between climate and periodic development of photosynthetic biomass. selected 15 Hornbeam plots (Carpinus betulus) from study area in a mountainous region from 520m to 1310m above sea level. Ground observations of hornbeam tree growth process from January to December 2004 in 15 day intervals were performed ...

The giant dobsonfly species Acanthacorydalis orientalis (McLachlan, 1899) is endemic to China and is well-known because of its remarkable large adult body size and enlarged male mandibles. However, the immature stages of this species, as well as all other Acanthacorydalis species are poorly known. In this paper we describe the last-instar larvae and pupae of A. orientalis for the first time. As...

Two sibling species, Metellina orientalis (Spassky, 1932) and M. kirgisica (Bakhvalov, 1974), occurring in the Middle East and Central Asia are redescribed and their distributions mapped. The previously unknown male of M. kirgisica is described for the first time. Stridulatory files on male chelicera of Metellina are also documented for the first time. The occurrence of M. kirgisica in Azerbaij...
