The lobe area is smallest at the beginning of each instar, independently of age.

These cells functionally correspond to elements of the normal endothelium but possess some exclusive ultrastructural features. The particular position of the cell nuclei and the relationship to the surrounding connective tissue (the loose perivascular connective tissue and interstitial vesicular cells) are shown. Irregular microvilli and pinocytosis vesicles are found on both inner and outer surfaces and oriented bundles of filaments occupy the central portion of the cytoplasm, anchoring to the plasmalemma. The hypothesis is advanced that these filaments are contractile in nature and, therefore, endothelial-like cells are retained capable of autoregulative processes, in order to adjust the calibre of the capillary lumen according to the rate of blood-tissue exchanges.","PeriodicalId":19014,"journal":{"name":"Monitore Zoologico Italiano-Italian Journal of Zoology","volume":"40 1","pages":"71-83"},"PeriodicalIF":0.0,"publicationDate":"2013-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85520039","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}

The present experiments have shown that the pseudergate moulting interval is of fairly variable duration, from 18 to 140 days, with a mean of about 70 days. Its average duration, however, is the same both in specimens differentiating into soldiers and in those undergoing a larval moult. Pseudergates display a rather short competence period for differentiation into soldiers during the second half of the moulting interval: possibly between the 45th and 60th day. Pseudergates are responsive only during their competence period, to the antagonistic stimuli exerted by the royals and soldiers respectively. The absence of soldiers prior to the 40th day does not elicit the differentiation of new soldiers (even in the presence of the reproductives);...","PeriodicalId":19014,"journal":{"name":"Monitore Zoologico Italiano-Italian Journal of Zoology","volume":"74 1","pages":"97-111"},"PeriodicalIF":0.0,"publicationDate":"2013-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88503881","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}

The b2 cells in the pars distalis showed a slight degranulation, 15 days after castration and an extensive degranulation, vacuolization and a significant increase in nuclear and cellular area, 1 month after castration.
