TLDR
The aim of this work was to study the feeding habits of the predator Brontocoris tabidus analyzing the salivary gland complex (SGC) and suggested that it could be considered an obligate zoophytophagous.Abstract:
The aim of this work was to study the feeding habits of the predator Brontocoris tabidus (Heteroptera: Pentatomidae) analyzing the salivary gland complex (SGC). The SGC was dissected and subjected to histological analyses and biochemical assays. Results showed that a pair of bilobed principal salivary glands and one pair of tubular accessory salivary glands form the SGC and different parts of salivary gland synthesizes similar substances. Lipases, a-amylase and trypsin-like enzymes were detected at both lobes of the principal salivary gland. These data together with observations related to the predator's diet suggested that it could be considered an obligate zoophytophagous.read more

TL;DR: The assassin bug Pristhesancus plagipennis has two distinct venom glands that produce venoms with distinct compositions that can be elicited by different stimuli, an evolutionary adaptation that has not been described for any other venomous animal.

Ultrastructure of the Digestive Cells in the Midgut of the PredatorBrontocoris Tabidus (Heteroptera: Pentatomidae) After Different Feeding Periods on Prey and Plants
Maria do Carmo Queiroz Fialho,José Cola Zanuncio,Clóvis Andrade Neves,Francisco S. Ramalho,José Eduardo Serrão +4 more
TL;DR: The ultrastructural features of the digestive cells in the anterior, medium and posterior regions of the midgut suggest that they play a role in digestive enzyme synthesis, ion and nutrient absorption, and storage and excretion of substances.

Prey digestion in the midgut of the predatory bug Podisus nigrispinus (Hemiptera: Pentatomidae)

TL;DR: Taking into account the distribution of hydrolases along P. nigrispinus midguts, carbohydrate digestion takes place mainly at the anterior midgut, whereas protein digestion occurs mostly in middle and posterior midGut, as previously described in seed- sucker and blood-feeder hemipterans.

Venoms of Heteropteran Insects: A Treasure Trove of Diverse Pharmacological Toolkits
TL;DR: The multiple ways venom is used by heteropterans suggests that further study will reveal heteropteran venom components with a wide range of bioactivities that may be recruited for use as bioinsecticides, human therapeutics, and pharmacological tools.

Zoophytophagous pentatomids feeding on plants and implications for biological control
TL;DR: This interaction contradicts the concept of ecological selectivity obtained for natural enemies through the placement of systemic insecticide in the soil as a selective method of deploying chemical control and predatory hemipteran conservation within the integrated pest management framework.

Improved silver staining of plant proteins, RNA and DNA in polyacrylamide gels
TL;DR: A new modification of silver staining is presented which utilizes two chemical properties of thiosulfate: image enhancement by pretreatment of fixed gels, and formation of soluble silver complexes which prevents unspecific background staining during image development.

TL;DR: Preliminary studies indicate that benzoyl dl -arginine p -nitroanilide hydrochloride is also hydrolyzed by papain, and that of l -LPA is in a more alkaline region than normally found for trypsin substrates.
