“…It is worth emphasising that intensive M. punctumalbum feeding on flowers in natural habitats may lead to damage to the reproductive organs of the flower and limit the generative reproduction of plants, thereby leading to reduction of their population. This issue seems important in light of our earlier findings that the generative reproduction of some European irises, e.g., I. spuria L., I. sibirica L., and I. pseudacorus L., is impaired by M. punctumalbum foraging (Skuhrovec et al, 2018). The authors of the work suggest that bumblebees are the best pollinators of throated-type flowers.…”

The marginal character of the I. aphylla populations, their spatial isolation, and the isolated 'island' localities (valley slopes, mineral islands surrounded by a peat bog) determine the varying characteristics of these populations (Franszczak-Być and Dąbrowska, 1993;Czarnecka, 1994;Wróblewska, 2003). Marginal populations naturally tend to become rare and endangered. They are usually described as populations with persistent low abundance, poor flowering, sparse fruiting, evident dominance of vegetative reproduction, or low phenotypic and genotypic variability (Mitka, 1997;Wróblewska, 2003Wróblewska, , 2008.All populations of I. aphylla in Wyżyna Lubelska Upland (central-eastern Poland) have been analysed since 1989 for determination of the species biology, phenology, abundance, and density as well as their ecological structure and contribution to the structure of xerothermic grasslands (Franszczak-Być and Dąbrowska, 1993;Czarnecka, 1994;Dąbrowska et al., 1998). Since 1991, integrated ex situ and in situ protection measures have been implemented. These measures include creation of conservation collections at the Botanical Garden of Maria Curie-Skłodowska University in Lublin, strengthening small-sized populations, restoration of historical localities, and improvement of habitat conditions (Dąbrowska et al., 2000;Kwiatkowski et al., 2004).All leafless iris populations in Wyżyna Lubelska Upland exhibit characteristic traits of a marginal population, i.e. sparse flowering and fruiting and clear dominance of Research ArticleThis work is licensed under a Creative Commons Attribution 4.0 International License.

“…The capsule wall thickness and seed wall thickness had the greatest influence on the first principal component defining I. aphylla ( Figure 4 and Figure 5 ). The examination of the morphology of seed capsules conducted by Skuhrovec et al [ 22 ] demonstrated that the weevil was not able to pierce the I. aphylla capsule due to its thickness, as the insect’s mouthparts are much shorter than the capsule wall thickness.…”

“…However, observations conducted in 2017 confirmed these reports only in the case of I. sibirica . They demonstrated that the weevil pierced seed capsules, which were a source of nutrients during insect development [ 22 ]. In the case of I. aphylla , the weevil foraged only on flowers and did not damage the seeds [ 23 ].…”

The aim of the study was to determine the correlation between the mechanical resistance of iris seed capsules and seeds to Mononychus punctumalbum foraging. The principal component analysis (PCA) demonstrated that the first main component referred to the variety type in 68%, and the second main component described the stage of the ontogenetic development of the plant in 26%. As indicated by the values of each parameter measured, all the parameters were found to exert a strong impact on the variability of the analyzed system. The occurrence of weevil infestation was also strongly but negatively correlated with seed wall thickness and capsule wall thickness. There was a correlation of seed max load and seed mass with the occurrence of the weevil. The analysis of the mechanical resistance of iris seed capsules (in June 9.28 N and September 6.27 N for I. sibirica and in June 6.59 N and September 2.94 N for I. aphylla) and seeds (in June 15.97 N and September 344.90 N for I. sibirica and in June 16.60 N and September 174.46 N for I. aphylla) showed significant differences between the terms and species. The PCA analysis revealed that the first variable was correlated with the occurrence of weevil foraging.
