“…This might directly impact the resulting plant microbiomes based on the bacteria associated with the incoming prey. Ants and other Hymenoptera are the insects most commonly attracted to Sarracenia pitcher plants ( 3 , 24 , 25 ); S. minor , specifically, seems to be an ant specialist ( 26 , 27 ). However, the microbiomes of ants tend to vary depending on their geographic location ( 28 – 30 ).…”

“…We thus analysed with general mixed models the total number of prey individuals trapped by pitchers, the number of flying prey individuals, the number of bees, moths, Diptera (flies, midges and mosquitoes), wasps (solitary, social and parasitoid wasps) and ants trapped by pitchers as dependent variables, testing taxon as an explanatory fixed variable and sampling day and plant identity as random variables. As the four taxa differed significantly in pitcher length ( S1 Fig ), which was likely to influence the number of prey [ 36 , 40 , 41 ], we corrected prey number by pitcher length in the analyses and considered this variable as a density (number of individuals / pitcher length). Density was square-root transformed to achieve normality of residuals.…”

“…A large part of the differences in the amounts of flying and terrestrial insects trapped in pitchers can be explained by differences in VOC emission [ 20 ]. In Sarracenia , morphology has hitherto been mainly invoked to explain these differences in prey capture [ 36 , 40 , 41 ]. But Ellison and Gotelli reported only few differences in prey spectra among Sarracenia species.…”

Sarracenia pitcher plants display interspecific differences in prey, so far only explained by pitcher morphology. We hypothesized that pitcher odours play a role in prey composition. We first compared odour and prey compositions among Sarracenia taxa grown together, forming a kinship gradient from S. purpurea known to capture primarily ants towards S. leucophylla known to capture many flying insects: S. purpurea, S. X mitchelliana, and S. X Juthatip soper & S. X leucophylla horticultural hybrids. We then measured several pitcher traits to disentangle the contributions of morphology and odour to prey variation. The pitcher odours were as diverse as those of generalist-pollinated flowers but with notable differences among taxa, reflecting their relatedness. VOC similarity analyses revealed taxon specificities, that mirrored those revealed by prey similarity analyses. S. X leucophylla stood out by being more specialised in flying insects like bees and moths and by releasing more monoterpenes known to attract flower visitors. S. X Juthatip soper trapped as many bees but fewer moths, sesquiterpenes contributing less to its scent. Ants and Diptera were the main prey of the other two with fatty-acid-derivative-dominated scents. Quantities of the different prey groups can be inferred 98% from quantities of the odour classes and pitcher dimensions. Two syndromes were revealed: ants associated with fatty-acid-derivatives and short pitchers; flying insects associated with monoterpenes, benzenoids and tall pitchers. In S. X leucophylla, emission rate of fatty-acid-derivatives and pitcher length explained most variation in ant captures; monoterpenes and pitcher length explained most variation in bee and moth captures; monoterpenes alone explained most variation in Diptera and wasp captures. Our results suggest that odours are key factors of the diet composition of pitcher plants. They support the hypothesis of perceptual exploitation of insect biases in carnivorous plants and provide new insights into the olfactory preferences of insect groups.

“…The pitcher's shape, size, and color are important in attracting prey (Gaume et al 2016;Peng and Clarke 2015;Stephens et al 2015). However, Buch et al (2015) and Gilbert et al 2018 reported no relationship between pitcher size and color and prey capture.…”

Abstract. Tarigan MRM, Aziz S, Tanjung IF, Pary C, Adlini MN, Jayanti UNAD, Ardianto, Ulfa AY. 2023. Morphology and pitcher's color Nepenthes in Batu Lubang Sibolga Area, North Sumatra Province, Indonesia. Biodiversitas 24: 1953-1962. The study's objective was to identify the size, color, and shape of a pitcher of Nepenthes found in the Batu Lubang Sibolga region. Purposive sampling is used as part of an exploratory approach in this study. Plot-based Nepenthes observation was conducted in the Sitahuis District, Central Tapanuli Regency, North Sumatra Province, Indonesia, to examine pitcher morphology and color. The results showed two species of Nepenthes, namely N. gracilis Korth and N. eustachya Miq, with two types of pitchers each, namely the lower and upper pitcher. The morphology of the Nepenthes pitchers has an almost similar shape but differs in the size of the pitcher circumference, where the lower pitcher is smaller than the upper pitcher. The bottom pitcher of N. gracilis has redwood (45%), and the upper pitcher is light green (55%), according to the proportion of observations of the color of the lower and upper pitchers of these two species. While the upper pitcher of N. eustachya is green with red dots (70%), the lower pitcher is light reddish green (30%). According to the study's findings, Nepenthes in the Batu Lubang Sibolga area required conservation intervention to preserve this species.
