    Description / Table of Contents: Summary It has been studied the male genital apparate of some casts and stages ofReticulitermes lucifugus and of winged reproductives ofPsammotermes assuanensis, Coptotermes sjöstedti, Schedorhinotermes javanicus, with particular attention to the form of the seminal vescicles, to their contenute, and to the testicle's activity.
    Abstract: Résumé Nous avons étudié la conformation des organes mâles de quelques castes et stades deReticulitermes lucifugus et des ailes dePsammotermes assuanensis, Coptotermes sjöstedti, Schedorhinotermes javanicus, en donnant une particulière attention à la forme des vésicules séminales, à leur contenu et à l'activité du testicule.

    Description / Table of Contents: Riassunto A pseudergati e a ninfe diK. flavicollis accompagnate da una coppia reale, sono stati comministrati estratti alcoolici di api regine (Apis mellifera L.). Rispetto ai gruppi di controllo, nei gruppi trattati si sono osservate più mute a reale di sostituzione e meno mute a soldato bianco; inoltre, le regine trattate hanno deposto meno uova. Si ritiene probabile che gli estratti di ape regina abbiano agito sui reali diK. flavicollis riducendo la loro capacità sia di inibire la differenziazione dei reali di sostituzione sia di stimolare la differenziazione dei soldati e anche riducendo la fertilità delle regine.
    Abstract: Résumé Des extraits alcooliques de reine d'Abeille (Apis mellifera L.) ont été absorbés par des pseudergates et des nymphes deK. flavicollis. Les Insectes traités ont eu davantage de mues aboutissant à des sexués de remplacement et moins de mues aboutissant à des soldats blancs que les Insectes témoins. Les reines traitées ont pondu moins d'œufs que les témoins. Il est probable que les extraits de reine d'Abeille ont agi sur les reproducteurs deK. flavicollis en réduisant leur capacité d'inhiber la différenciation de sexués de remplacement, de provoquer la différenciation de soldats et de réduire la fertilité des reines.
    Notes: Summary Alcoholic queen bee extracts (Apis mellifera L.) were administered toK. flavicollis pseudergates and nymphs. In comparison with the control groups the treated groups had more moults into supplementary reproductives and fewer moults into white soldiers; the treated queens laid fewer eggs. There are evidences that the queen bee extracts acted mainly on theK. flavicollis reproductives reducing their ability both to inhibit the differentiation of supplementary reproductives and to stimulate the differentiation of soldiers, and reducing the queens' fertility.

    Influence of reproductives on tunnelling behaviour inKalotermes flavicollis Fabr. (Isoptera: Kalotermitidae) (1989)

    Description / Table of Contents: Resume On a isolé des groupes deK. flavicollis de leur colonie afin d'étudier leur manière de creuser un nouvel abri, dans le mélange agar/sciure. Dès le premier jour les insectes ont creusé plusieurs galeries, puis les creusements ont été effectués avec grande régularité. Enfin, quelques galeries ont été comblées de fragments de bois. Il existe une corrélation entre la longueur des galeries comblées et la longueur de celles qui ont été creusées. La présence des sexués stimule l'activité des insectes dès le premier jour et ceux-ci creusent des nids plus vastes constitués d'un nombre plus élevé de galeries.
    Notes: Summary Groups ofKalotermes flavicollis were isolated from their wild colony, in order to study their digging of a new shelter in a mixture of agar/sawdust. On the 1st day the insects dug a lot of tunnels, and then the digging went on with great regularity. Some tunnels were later filled with sawdust. There is a correlation between the total length of the dug tunnels and that of the filled ones. The reproductives stimulated the insects' activity right from the beginning and so the latters dug wider nests made of longer tunnels and with more branches too.

    Notes: Riassunto Per studiare l'influenza del farnesato di etile (FAEE) sulla differenziazione delle caste, si sono trattate sostanza. Si è ottenuta la differenziazione sia di soldati, sia di intercaste: tra soldato e pseudergate e tra soldato e reale di sostituzione; la frequenza di questi tipi di mute aumenta con la dose di FAEE usata, mentre diminuisce la frequenza delle mute larvali e reale di sostituzione. Il tempo medio intercorso tra l'inizio del trattamento e le mute larvali o a reale di sostituzione è stato più lungo che per i controlli, è stato in invece più breve per le mute a soldato e a intercasta di soldato.
