E.-E. Duvillard de Durand , "Principes et formules du calcul des probabilités pour assigner les limites des variations des événements naturels (1813)", edizione a cura di L. Dell'Aglio e G. Israel, con un saggio introduttivo di L. Dell'Aglio e G. Israel
No full textEmmanuel-Étienne Duvillard de Durand (1755-1832) was known for his actuarial activities and for the construction of life tables, but his contribution to the analysis of social mathematics and the mathematical modelling of mortality long went unrecognized. His attempts to enter the prestigious Académie des Sciences and his ambition to add a probabilistic dimension to population statistics confirm that he was not only a brilliant mathematician, but also a scholar in the noblest sense of the term, to whom this book pays tribute. Principes et Formules du calcul des probabilités pour assigner les limites des variations des événements naturels, a treatise on the «principles and formulae of probability calculation to define the limits of variation in natural events» represents the culmination of his research, recognized in his time by scholars such as Lagrange, Legendre et Laplace, but later condemned to oblivion by the vicissitudes of history and a veritable conspiracy of silence. Duvillard’s previously unpublished work, transcribed and edited for the first time in this book, was written in 1813. Picking up on ideas set forth by the mathematician Jean-Henri Lambert in that same year, he examines mortality with a view to constructing an equation to describe the progressive extinction of a human generation. His work thus represents a turning point in the study of demographic phenomena and a first attempt to apply principles of probability calculation to population science. This is a truly pioneering text which aims to provide an exact evaluation of the limits to be defined when estimating the size of a population. The editors of this treatise – Giorgio Israel, who first uncovered these unpublished archives, and Luca Dell’Aglio – have accomplished a considerable feat. Together, they have patiently deciphered, dissected and transcribed this handwritten text and authored an accompanying essay which places the document in its historical and scientific context. Their work is a historical tribute, aiming to render justice to a man of exceptional qualities by acknowledging his role in the history of science

Metoecus paradoxus (Linnaeus, 1760) (Coleoptera: Ripiphoridae), a new species for the fauna of Israel
Get PDFThe Ripiphoridae (wedge-shaped beetles) contain approximately 450 species worldwide. Like the Meloidae, many wedge-shaped beetles are hypermetamorphic parasitoids. The majority of them attack wasps and bees whilst others attack cockroaches and beetles (Ptinidae and Cerambycidae) (Batelka et al. 2018). The first record of a ripiphorid species from Israel was published by Sahlberg (1912), who reported that Ptilophorus dufourii (Latreille, 1817) was collected at Dayr Aban (a village East of Bet Shemesh, Judean Hills) by Unio Saalas. Pic (1927) mentioned Pterydrias debilis Reitter, 1895, and Bodenheimer (1937) records two species for Israel, Macrosiagon bimaculata (Fabricius, 1787) and Macrosiagon ferruginea (Fabricius, 1781). Argaman and Mendel (1988) reported two Ripiphoridae species as new for Israel, Ripidius vaulogeri Chobaut, 1893 and Evaniocera dufouri Latreille, 1817, but the latter had been already published by Sahlberg (1912). Chikatunov et al. (2006) added Macrosiagon praeusta (Gebler, 1829) and Ripiphorus subdipterus Bosc, 1792 to the list of Israeli wedge-shaped beetles. Metoecus paradoxus (Linnaeus, 1760), commonly referred to as ‘the wasp nest beetle’, is hereby recorded in Israel for the first time. On the 23rd of June 2018 a large nest of Vespula germanica (Fabricius, 1793) was removed by the second author from the vicinity of Merom Golan (a kibbutz at the Golan Heights in the northern part of Israel; 33°08'N 35°46'E). The ruined nest was then exposed to pesticides. Near the nest a female of M. paradoxus was observed. Soon afterward a search inside the ruined nest yielded dead and still alive adults and pupae of M. paradoxus. In total, 33 specimens of M. paradoxus were found: nine pupae and seven newly hatched adults (five females and two males) were found inside closed cells, and 16 adults (14 females and three males) were found freely in the nest. A male and three females were found alive. The living females were observed and photographed while laying eggs on different parts of the nest. A pair of adults is currently deposited at the collection of the first author, housed at the Steinhardt Museum of Natural History, Tel Aviv University.

A new record for the darkling beetle fauna of Israel: Akis subtricostata Redtenbacher, 1850 (Coleoptera: Tenebrionidae)
Get PDFThe distribution range of Akis subtricostata covers Iran, Iraq, Syria (Löbl et al. 2008; Eleyjian 2010) and Turkey (Keskin & Yağmur 2008). Löbl et al. (2008) does not list this species for Jordan; however, it has already been recorded from a few localities in this area. Katbeh-Bader (1996) mentioned it from Dhulayl and Waitzbauer et al. (2004) referred to the area of Petra and Wadi Arava (which is treated here as 'Arava Valley). The senior author collected three specimens of Akis subtricostata (Fig. 1) in the southern area of the 'Arava Valley, Israel on the 12th of September 2014. This is the first record of this species in Israel. Further examination of the Akis specimens deposited in the Steinhardt Museum of Natural History Tel Aviv University, Israel (TAU), revealed three more specimens, all collected in 1968 by J. Klapperich (Bonn) during his 1956–1969 trip to Jordan. Bytinski-Salz (1969: 186) noted on Klapperich’s collecting effort that “the material has been distributed to specialists, but nothing has been published so far”. These three specimens are now the earliest known record from Jordan. It seems that these specimens were sent from Europe back to Israel without being taxonomically treated, and so Akis subtricostata remained unknown from Jordan until the publication of Katbeh-Bader (1996), which was based on a single specimen from Dhulayl. In Israel, the beetles were collected around midnight with a flashlight. They were seen wandering actively on semi stabilized sand dunes near Samar.
