Ultramorphological analysis of the venom glands and their histochemical relationship with the convoluted glands in the primitive social paper wasp Polistes versicolor (Hymenoptera: Vespidae)
(Centro de Estudos de Venenos e Animais Peçonhentos, 2005-06)
The venom glands are part of the most important defense weapon in Aculeata: the venom apparatus. The arrangement of these glands can vary among species, but in general they are composed of long secretory tubules connected ...
Study of the venom glands in Ectatomma quadridens (Hymenoptera: Formicidae). Evolutionary hypothesis in subfamily ponerinae
(2005-06-01)
The venom glands of worker ants of the species Ectatomma quadridens morphologically resemble an elongated sac or reservoir ending in a narrower portion that has the function of releasing the secretion to the exterior. Two ...
Morphohistological study of the venom gland in workers of the ant Pachycondyla striata F. Smith (Hymenoptera : Ponerinae)
(California State University, 2003-01-01)
Themorphology of the venom gland in workers of the ant Pachycondyla striata (F. Smith) (Hymenoptera: Ponerinae) consists of an elongated sac that is directly connected to the sting apparatus. Three distinct regions compose ...

Morphology and Histochemistry of the Venom Apparatus in Different Castes of the Ant Ectatomma vizottoi (Formicidae: Ectatomminae)
(Univ Estadual Feira Santana, 2018-06-01)
The elimination of toxins via a venom gland by some ant species is a component of a larger mechanism for capturing prey and defense. The present study describes the morphology and histochemistry of the venom apparatus of ...
Juvenile Hormone Effect on the Venom Gland Secretory Cycle in Workers of Apis mellifera (Hymenoptera, Apidae)
(2004-02-17)
The present investigation analyzed the influence of Juvenile Hormone (JH) on the venom glands of Apis mellifera workers through protein dosage and electrophoresis of venom gland extracts of newly emerged workers which were ...

Cytochemical studies of the nuclei of the venom glands' cells of Apis mellifera (Hymenoptera, Apidae)
(Japan Soc Histochem Cytochem, 2004-01-01)
Cytochemistry studies of the nuclei of the venom glands' cells of worker bees of Apis mellifera indicated that there is a higher activity in the young workers while there is a predominance of degenerative characteristics ...
Sympathetic outflow activates the venom gland of the snake Bothrops jararaca by regulating the activation of transcription factors and the synthesis of venom gland proteins
(COMPANY OF BIOLOGISTS LTD, 2009)
The venom gland of viperid snakes has a central lumen where the venom produced by secretory cells is stored. When the venom is lost from the gland, the secretory cells are activated and new venom is produced. The production ...
Alterations induced by juvenile hormone in glandular cells of the Apis mellifera venom gland I - Application on the larvae (Hymenoptera: Apidae)
(2002-01-01)
Histological analyses were made in order to evaluate the effects of the topic application of a synthetic juvenile hormone (JH-III Sigma) on the development of the venom glands in workers of Apis mellifera. Three experimental ...
