Visual communication without any water contact between the test tank male and the female in the internal transparent container (Fig. 1 A); neither isospecific nor heterospecific pairs of either species showed reproductive behavioural changes. 2. Chemical communication through continuous water circulation between the female's external optically isolated glass container and the male's test tank (Fig. 1 B); an increase of aggressiveness and colour followed by nest-building by the male was induced. This test was performed on isospecific and heterospecific pairs of both species. 3. Actual contact (Fig. 1 E), isospecific pairs began their regular reproductive behaviour; heterospecific pairs displayed no reproductive behavioural changes. 4.

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 Leydig cells, which are more abundant than in any other mammalian species, are large and of two types, although intermediate stages exist. Type I show a clear nucleus devoid of large eterochromatine blocks, a large cytoplasm; mitochondria with poorly developed cristae are packed in the centre of the cell. The SER, with enlarged tubules and vesicles, is well developed at the periphery of the cell. The RER is scanty. Type II cells show a nucleus richer in eterochromatin, mitochondria equipped with many tubular cristae and more scattered, a SER made up of narrow tubules and a more abundant RER. The Δ-5-3-β-HSDII reaction is strongly positive in all the cells. The two cellular types probably correspond to different functional stages.

The total FAA content and other constituents present in the excreta decreased during larval growth. Individually, most of the FAA followed this broad pattern of quantitative change.

Neurosecretory fibres, appear heavily electrondense as the elementary granules become more densely packed. The fibres often break into fragments and appear widely separated from one another, modifying the general pattern of the pars nervosa. Both ependymal cells and pituicytes are characterized by a strong macrophagic activity towards degenerating nerve fibres which often appear to be engulfed by them.

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.
