“…Some other Diptera larvae, such as Nepenthosyrphus (family Syrphidae), Dasyhelea (family Ceratopogonidae), and the larvae of family Empididae, might also be found in the pitchers of Nepenthes. The Diptera larvae inhibiting in the pitchers might contribute to assist the digestion mechanism [19,20].…”

Nepenthes traps prey using its pitcher as an adaptation to thrive in low-nutrient habitats. This study aims to identify and analyze the composition of prey trapped in the pitchers of six Nepenthes species occur in Pematang Gadung. The preys were collected by purposive sampling from five pitchers of each species (N. ampullaria, N. bicalcarata, N. gracilis, N. mirabilis, N. rafflesiana and, N. x hookeriana) in two habitat types (peat swamp forest and heath forest). The diversity of prey trapped by Nepenthes was analyzed using Past Software Version 4.0. based on the Shannon index (H′) for each species and the Jaccard index to compare prey diversity between habitat types. A total of 1149 individual prey was collected, comprise seven orders of insects (Class Insecta) and one order of arachnids (Class Arachnida). The predominant prey was the insect of order Hymenoptera (85.90%), especially the family Formicidae. The other orders of insects were Diptera (10.36%), Coleoptera (1.48%), Blattodea (0.96%), Orthoptera (0.61%), and Hemiptera (0.09%). The order of arachnid was Araneae (0.61%). The most diverse prey was found in the pitchers of N. gracilis (H′= 0.79). The diversity of prey trapped by Nepenthes in both habitats has high similarity (JI = 0.71).

“…Carnivorous plants (CPs) attract, trap, degrade, and absorb tiny animals in order to supplement their nutrient supply [ 1 , 2 ]. Prey digestion and uptake in CPs is functionally similar to the processes observed in the digestive systems of animals [ 3 , 4 ]. However, in CPs the functional features are all performed in one spot: the trap leaf.…”

“…However, in CPs the functional features are all performed in one spot: the trap leaf. Digestion and uptake are accomplished either by enzymes produced by the plant itself, or by mutualistic trap inquilines [ 4 , 5 ]. In both cases, prey degradation results in a complex mixture of inorganic ions such as K + or PO 4 3− [ 6 ], small organic molecules such as amino-sugars from chitin, amino acids, peptides of various size, and macromolecules including whole proteins [ 7 , 8 , 9 ].…”

Carnivorous plants adsorb prey-derived nutrients partly by endocytosis. This study quantifies endocytosis in Drosophyllum lusitanicum, Drosera capensis, Drosera roseana, Dionaea muscipula and Nepenthes × ventrata. Traps were exposed to 1% fluorescent-labeled albumin (FITC-BSA), and uptake was quantified repeatedly for 64 h. Formation of vesicles started after ≤1 h in adhesive traps, but only after 16 h in species with temporary stomach (D. muscipula and N. × ventrata). In general, there are similarities in the observed species, especially in the beginning stages of endocytosis. Nonetheless, further intracellular processing of endocytotic vesicles seems to be widely different between species. Endocytotic vesicle size increased significantly over time in all species except in D. capensis. Fluorescence intensity of the endocytotic vesicles increased in all species except D. muscipula. After 64 h, estimates for FITC-BSA absorption per gland ranged from 5.9 ± 6.3 ng in D. roseana to 47.8 ± 44.3 ng in N. × ventrata, demonstrating that endocytosis substantially contributes to the adsorption of prey-derived nutrients.

“…Extrafloral nectar lures insects and also establishes slippery surfaces on the pitcher lip ( Heliamphora ) [ 14 , 15 ]. Other metabolites such as volatiles attract insects [ 16 , 17 , 18 ] while pigments create striking patterns both in the visible and UV light spectrums [ 19 , 20 ]. Compounds with chemopreventive and therapeutic potential belonging to three main groups (naphthoquinones, flavonoids, phenolic acids) have already been isolated from carnivorous plants of several genera, mainly Dionaea , Drosera and Nepenthes [ 21 , 22 ].…”

Carnivorous plants have fascinated researchers and hobbyists for centuries because of their mode of nutrition which is unlike that of other plants. They are able to produce bioactive compounds used to attract, capture and digest prey but also as a defense mechanism against microorganisms and free radicals. The main purpose of this review is to provide an overview of the secondary metabolites with significant biological activity found in the Sarraceniaceae family. The review also underlines the necessity of future studies for the biochemical characterization of the less investigated species. Darlingtonia, Heliamphora and Sarracenia plants are rich in compounds with potential pharmaceutical and medical uses. These belong to several classes such as flavonoids, with flavonol glycosides being the most abundant, monoterpenes, triterpenes, sesquiterpenes, fatty acids, alkaloids and others. Some of them are well characterized in terms of chemical properties and biological activity and have widespread commercial applications. The review also discusses biological activity of whole extracts and commercially available products derived from Sarraceniaceae plants. In conclusion, this review underscores that Sarraceniaceae species contain numerous substances with the potential to advance health. Future perspectives should focus on the discovery of new molecules and increasing the production of known compounds using biotechnological methods.
