Gonadotropic and physiological functions of juvenile hormone in Bumblebee (Bombus terrestris) workers. [PDF]
PLoS ONE, 2014 The evolution of advanced sociality in bees is associated with apparent modifications in juvenile hormone (JH) signaling. By contrast to most insects in which JH is a gonadotropin regulating female fertility, in the highly eusocial honey bee (Apis ...

HEMOLYMPH PROTEINS AND REPRODUCTION IN PERIPLANETA AMERICANA: THE NATURE OF CONJUGATED PROTEINS AND THE EFFECT OF CARDIAC-ALLATECTOMY ON PROTEIN METABOLISM [PDF]
The Biological Bulletin, 1967 1. The nature and behavior of the conjugated proteins in the hemolymph of adult female Periplaneta americana (L.) have been studied in relation to the ovarian cycle, using disc electrophoresis in polyacrylamide gel and various staining procedures. It is shown that there may be not only a change in the relative concentration of the different protein ...

European Journal of Entomology, 2006 Mechanisms of the suppression of gonadotropic activity of the corpus allatum (CA) in macropterous females were compared with those previously reported for either diapause or starving non-diapause brachypterous females by reciprocal transplantations of ...

European Journal of Entomology, 2008 We studied the development of the indirect flight muscles and reproductive organs in long-winged (macropterous) adults of the flightless bug Pyrrhocoris apterus (L.) and the factors involved in flight muscles histolysis by means of total protein analysis.

Memorias do Instituto Oswaldo Cruz, 1991 When 4th instar nymphs of Panstrongylus megistus are fed with a saturant blood meal, there is an intense proliferation of the spermatogonia. At the end of the intermoult, the older spermatogonial cysts differentiate into 1st primary spermatocyte cysts ...

Juvenile hormone and division of labor in honey bee colonies: effects of allatectomy on flight behavior and metabolism [PDF]
Journal of Experimental Biology, 2003 SUMMARY Three experiments were performed to determine why removal of the corpora allata (the glands that produce juvenile hormone) causes honey bees to fail to return to their hive upon initiating flight. In Experiment 1, the naturally occurring flights of allatectomized bees were tracked with radar to determine whether the deficit is ...
