The salivary gland and salivary enzymes of the giant waterbugs (Heteroptera; Belostomatidae).
TLDR
Differences in salivary enzyme composition between large and small species of giant waterbug (Lethocerus uhleri, Lethocerinae and Belostoma lutarium, Belostomatinae, respectively) are described and the first reported evidence of protease production in the accessory salivaries in the Heteroptera is reported.
TECHNIQUES FOR PREPARING CRUSTACEANS FOR SCANNING ELECTRON MICROSCOPY
Several techniques for preparing the internal and external surfaces of crustaceans for SEM are described in detailed flow-chart form. Suggestions are given for improving fixation, cleaning, and
Structure and Function of the Mouthparts and Salivary Gland Complex of the Giant Waterbug, Belostoma lutarium (Stål) (Hemiptera: Belostomatidae)
TLDR
The morphology of the feeding structures of B. lutarium agrees with the general hemipteran feeding plan and the structure and function of the mouthparts and salivary gland are adapted for the predaceous feeding habits of Belostomatidae.
Parasitic and Phoretic Mites Associated with Neotropical Harvestmen from Trinidad, West Indies
TLDR
Overall, the prevalence of infestation for Neotropical harvestmen from the Caribbean island of Trinidad was 9.9%, with significant interspecific variation in the intensity of mite infestation and significant differences in parasitism of hosts between habitats.
Salamander scent marks: site of production and their role in territorial defence
TLDR
The results of these two experiments suggest that the post-cloacal gland produces territorial scent marks and that scent marks do not cause avoidance by conspecifics.
Diversity and Habitat Use of Neotropical Harvestmen (Arachnida: Opiliones) in a Costa Rican Rainforest
TLDR
The analysis of covariance supports the hypothesis that leg length is related to climbing behavior for several species belonging to Eupnoi and Laniatores, and provides the first insights into the diverse assemblage of harvestmen inhabiting a wet forest at La Selva Biological Station, Costa Rica.
Morphology of the Midgut–Hindgut Juncture in the Ghost Shrimp Lepidophthalmus louisianensis (Schmitt) (Crustacea: Decapoda: Thalassinidea)
TLDR
Vivisection, histological studies, and paraffin-carving have been applied to reconstruct morphology of these components and characterize constituent tissues and unique features of these structures may relate to behavioral, feeding and metabolic adaptations in this obligate fossorial crustacean.
Identifying Areas of Chemical Signal Production in the Red-Backed Salamander, Plethodon cinereus
TLDR
It is suggested that males of Plethodon cinereus may have several secretory sources that produce chemical signals (pheromones) used in intraspecific communication.
Ultrastructural changes in the Malpighian tubules of the house cricket, Acheta domesticus, at the onset of diuresis: A time study
TLDR
This work presents the ultrastructural changes that occur in the mid‐tubule of the house cricket, Acheta domesticus, following exposure to the second messenger analog, dibutyryl cAMP, over the period from 15–420 sec and discusses several possible roles for these changes in terms of rapid fluid transport.
