The brachial plexus is outlined at 82–84 hr of incubation and it is definitively constituted 36 hr later, as regards differential contribution of the spinal nerves and emergence of peripheral trunks. The spinal nerves XII to XVII participate in plexus formation; the contribution of the XII and XVII nerves is minor but constant. The nerve fibres enter the arm at about 90 hr and the innervation of the arm and forearm is already outlined at the end of the fifth day of incubation. In the hand, innervation begins by the sixth day, reaching the phalangeal region toward the end of the eleventh day. The progress of the wing innervation takes place in a proximo-distal sequence, in parallel with the unfolding of the organogenetic processes of the mesenchymal territories of the bud. The wing nerve pattern attains its definitive arrangement, typical of the adul...","PeriodicalId":19014,"journal":{"name":"Monitore Zoologico Italiano-Italian Journal of Zoology","volume":"45 1","pages":"81-98"},"PeriodicalIF":0.0,"publicationDate":"2013-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78747695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(HERMANN & DIRKS, 1974), has now been recorded in the European Polistes gallicus (L.), P. foederatus (Kohl) and P. nimpha Christ (Hymenoptera Vespidae). An ant repellent is smeared on the nest pedicel during this movement which the European Polistes perform—together with other defense patterns—not only in the presence of ants but also in response to small amounts of chemical irritants (formic acid, acetic acid). The secretion, applicated by means of the Van der Vecht's organ (VAN DER VECHT, 1968), effectively repels ants which normally prey on the nests of Polistes. Tested on glass capillary tubes, the repellent loses its effect between 2 and 4 hr after application. There is no connection between rubbing and hierarchy among associated females on polygynic spring nests of P. g...","PeriodicalId":19014,"journal":{"name":"Monitore Zoologico Italiano-Italian Journal of Zoology","volume":"33 1","pages":"129-142"},"PeriodicalIF":0.0,"publicationDate":"2013-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80135742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A noticeable thickened hypobranchial gland is present in the mantle of Murex brandaris, while in the other two species the gland is reduced. In Viviparus viviparus and Pomatias elegans there is an extremely simple gland in the mantle without purpurigen cells. The gland structure does not change during the seasons of the year in Murex and in Viviparus: on the contrary, in Pomatias the development of this gland is quite different in autumn and in spring. This fact, in our opinion, may be related to the terrestrial habitat of this species.","PeriodicalId":19014,"journal":{"name":"Monitore Zoologico Italiano-Italian Journal of Zoology","volume":"63 1","pages":"63-76"},"PeriodicalIF":0.0,"publicationDate":"2013-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76696956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
