Author:

Subject:
Atta sexdens rubropilosa; antibiotics; antiseptics; evolution; fungus gardens; leaf-cutting ants; microorganisms; nesting; organic matter; organic soils; pathogens; queen insects; risk; soil depth; soil horizons
Abstract:
... Queens of leaf-cutting ants found their nests singly, each consisting of a vertical tunnel and a final horizontal chamber. Because of the claustral mode of nest founding, the queen and/or her initial fungus garden are exposed to threats imposed by several soil pathogens, and the antibiotic secretions produced by their metapleural glands are considered a main adaptation to deal with them. Nests of ...

Subject:
Vespula vulgaris; chemical analysis; cleaning; exocrine glands; legs; males; social insects; surveys
Abstract:
... This study brings a survey of the exocrine glands in the legs of Vespula vulgaris wasps. We studied workers, males, virgin queens as well as mated queens. A variety of 17 glands is found in the different leg segments. Among these, five glands are novel exocrine structures for social insects (trochanter-femur gland, ventrodistal tibial gland, distal tibial sac gland, ventral tibial gland, and ventr ...

Subject:
Brachinus; catalase; fluorescence; fluorescence microscopy; hydrogen peroxide; hydroquinone; mechanical stress; scanning electron microscopy; ultrastructure
Abstract:
... This paper provides the first comparative anatomical study of the explosive pygidial defensive system of bombardier beetles in species classified in three brachinine subtribes: Brachinus (Brachinina), Pheropsophus (Pheropsophina) and Aptinus (Aptinina). We investigated the morphology and ultrastructure of this system using optical, fluorescence, and focused ion beam (FIB/SEM) microscopy. In doing ...

Euphorbia pulcherrima; Frankliniella occidentalis; Megalurothrips sjostedti; aggregation pheromones; beans; flowers; light microscopy; males; transmission electron microscopy; ultrastructure
Abstract:
... Sternal pores are important features for identification of male thrips, especially within the subfamily Thripinae. They vary in shape, size and distribution even between species of one genus. Their functional role is speculated to be that of sex- and/or aggregation pheromone production. Yet, sexual aggregations are not reported in Echinothrips americanus, known to have sternal pores, while we obse ...

5. Tarsomere and distal tibial glands: Structure and potential roles in termites (Isoptera: Rhinotermitidae, Termitidae)

Abstract:
... Social insects have numerous exocrine glands, but these organs are understudied in termites compared to hymenopterans. The tarsomere and distal tibial glands of the termites Heterotermes tenuis, Coptotermes gestroi and Silvestritermes euamignathus were investigated by scanning and transmission electron microscopy. Pore plates are visible in scanning micrographs on the distal tibial surfaces and on ...

6. Uncovering head gland diversity in neotropical Polistinae wasps (Hymenoptera, Vespidae): Comparative analysis and description of new glands

Subject:
Vespidae; animals; evolution; exoskeleton; head; hypopharyngeal glands; scanning electron microscopy; social insects; tropics
Abstract:
... Exocrine glands are involved in several wasp colony activities; however, the number of known glands in the Vespidae is rather low when compared to other social insect groups. The aim of this study is to survey the head of Neotropical social wasps and to provide a detailed comparative study of the glands found in the Polistinae. A total of 33 species distributed over 13 genera were studied with ser ...

Abstract:
... The digger wasp species Ampulex compressa produces its venom in two branched gland tubules. They terminate in a short common duct, which is bifurcated at its proximal end. One leg is linked with the venom reservoir, the other one extends to the ductus venatus. Each venom gland tubule possesses, over its entire length, a cuticle-lined central duct. Around this duct densely packed class 3 gland unit ...

Abstract:
... The fine structure of the interommatidial exocrine glands, found in the compound eyes of the water strider Aquarius remigis, is described using light, scanning, and transmission electron microscopy. The glandular pores of the glands are specialized into minute “nail-headed” structures (NS), which are described for the first time in arthropod compound eyes. Each NS is composed of two components: a ...

Blattodea; Termitidae; exocrine glands; secretion; synapomorphy
Abstract:
... Termites have developed many exocrine glands, generally dedicated to defence or communication. Although a few of these glands occur in all termite species, or represent synapomorphies of larger clades, others are morphological innovations of a single species, or a few related species. Here, we describe the nasus gland, a new gland occurring at the base of the nasus of Angularitermes soldiers. The ...
