The Salivary Pumping Apparatus of Belostomatidae (Heteroptera)
The Canadian Entomologist, 1964The heteropteran cephalic endoskeleton is difficult to study in dissections, due to its small size and to the delicacy of many of its membranous components. These difficulties are less of a handicap in dissections of the giant water bug Lethocerus (Belostomatidae), and it is possible to observe, in this insect, details of the salivary pumping apparatus

The salivary gland and salivary enzymes of the giant waterbugs (Heteroptera; Belostomatidae)
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2006The giant waterbugs are predators that utilize extra-oral digestion and are known to capture a wide variety of prey. Herein we describe the differences in salivary enzyme composition between large and small species of giant waterbug (Lethocerus uhleri, Lethocerinae and Belostoma lutarium, Belostomatinae, respectively). The saliva of L.

Muscle Regression in Belostomatid Bugs (Heteroptera: Belostomatidae)
Aquatic Insects, 2001Differential flight muscle regression was registered in Belostoma elegans (Mayr, 1871) and B. oxyurum (Dufour, 1863). A two year survey in contrasting habitats showed the preference for the more stable ones by B. oxyurum, and the more unstable ones by B. elegans. Fibrillar muscles were regressed in most of the B.

Attachment forces of the hemelytra-locking mechanisms in aquatic bugs (Heteroptera: Belostomatidae)
Journal of Insect Physiology, 2003Combined hemelytra-locking system of Heteroptera, consisting of several locking mechanisms, aids the mechanical stabilisation of the body at rest, resists external loads, and keeps air stored with the option to easily unlock hemelytra prior to flight. The resistance to unlocking of the hemelytron was measured (in mN) with the aid of a load cell force ...

Belostomatidae (Insecta: Heteroptera) as Intermediate Hosts of Digenetic Trematodes
Comparative Parasitology, 2002Three species of Belostoma Latreille, 1807 (Insecta, Heteroptera) were found to be intermediate hosts of digenetic trematodes of the genus Stomylotrema Looss, 1900, parasitic in birds. Several infected specimens of Belostoma elegans (Mayr, 1871) and Belostoma oxyurum (Dufour, 1863) were collected in the Arroyo Zapata, Province of Buenos Aires ...

Ecology of giant water bugs (Hemiptera: Heteroptera: Belostomatidae)
Entomological Science, 2018AbstractGiant water bugs (Heteroptera: Belostomatidae) are aquatic predators of freshwater habitats, and include ca. 150 species distributed throughout the world's subtropical and tropical areas. They have unique mating systems, which involve female competition, and exhibit paternal care, wherein males attend eggs laid by the females on emergent plants

THE ENDOSKELETAL SALIVARY PUMPING APPARATUS IN REPRESENTATIVE BELOSTOMATIDAE (HETEROPTERA)
Canadian Journal of Zoology, 1963The salivary pumping apparatus in representatives of the aquatic family Belostomatidae (Insecta) is discussed. Observations were based upon dissections of adult Lethocerus and histological serial sections through the heads of nymphal Belostoma. The simple, two-layered salivary pump, its afferent and efferent openings, and the paired afferent and ...
