“…In order to explore new possible sources of active metabolites toward stored product pest species, here we evaluated the composition of secondary metabolites and the insec-ticidal activity of EOs obtained separately from flowers, leaves, and stems of S. bocconei collected in Sicily against two coleopteran species attacking stored commodities: Sitophilus oryzae L. (Coleoptera: Curculionidae) and Callosobruchus maculatus (F.) (Coleoptera: Bruchinae). The different parts from the same plant species have, in fact, different chemical compositions and consequently, different biological activities as observed in other studies [39].…”

In this study, the chemical composition of the essential oils (EOs) obtained from different aerial parts (flowers, leaves, and stems) of Seseli bocconei Guss., a wild species endemic of Sicily, was investigated. Furthermore, the EOs’ biocidal effects towards two pests of stored products, Sitophilus oryzae and Callosobruchus maculates, were evaluated. This activity was evaluated in Petri dish bioassays to establish the survival rate of adults treated with the EOs comparing them with solvent and a commonly used insecticide (pyrethrum). The data obtained from the toxicity bioassay evidenced that stems’ EOs and leaves’ EOs have a contact/fumigation effect towards the two insect species tested, while the EOs from the flowers did not exhibit a different mortality than the solvent. The EOs from the stem and leaves of S. bocconei, tested at 10 mg/petri dish, determined a LT50 of 53.38 and 42.97 h, respectively, on S. oryzae adults, and of 45.23 and 42.97 h, respectively, on C. maculatus adults. The promising bioactivity of S. bocconei leaves’ EOs and stems’ EOs toward S. oryzae and C. maculatus is encouraging in the perspective to test these oils and their main constituents for further experiments in the laboratory and field.

“…According to previously reported studies, both Caryophyllene and Citronellol exhibited good contact activity against T. castaneum . And Cuminal and Caryophyllene exhibited synergistic contact activity against T. castaneum in all experimental ratios [33–35] . Although there are no reports of Sandaracopimaradiene and Kaura‐16‐ene insecticides, however, studies have shown that Rhododendron caucasicum contains a large amount of Sandaracopimaradiene and small amount of Kaura‐16‐ene, and the EO of R. caucasicum showed the antimicrobial activity against Gram‐positive bacteria [36–37] .…”

In order to assess the repellent, contact, and fumigant properties of three essential oils (EOs) from Rhododendron species in China against adults of Tribolium castaneum, Lasioderma serricorne, Sitophilus oryzae, this study analyzed their chemical components. The three EOs were extracted by hydrodistillation from leaves of Rhododendron species, including R. davidsonianum, R. heliolepis and R. strigillosum. Sesquiterpenoids and monoterpenes were the main components of the three EOs that were detected by GC/MS and GC-FID. α-Pinene, β-Caryophyllene, α-Humulene, Kaura-16-ene and Sandaracopimaradiene was among the comparatively high components. In this study, the EOs of three Rhododendron species demonstrated repellent activities against T. castaneum and L. serricorne in 2 h and 4 h exposure, but the repellent activity to S. oryzae was not obvious. The three EOs from R. davidsonianum, R. heliolepis and R. strigillosum also had contact activities and fumigant activities against the Tribolium castaneum (LC 50 = 13.453 mg/L air, 4.728 mg/L air, 4.529 mg/L air and LD 50 = 15.027 μg/adult, 15.017 μg/adult, 10.994 μg/adult, respectively), Lasioderma serricorne (LC 50 = 8.584 mg/L air, 6.044 mg/L air, 6.355 mg/L air and LD 50 = 4.566 μg/adult, 7.067 μg/adult, 3.652 μg/adult, respectively) and Sitophilus oryzae (LC 50 = 3.304 mg/L air, 6.795 mg/L air, 7.130 mg/L air and LD 50 = 10.200 μg/adult, 15.021 μg/ adult, 9.178 μg/adult, respectively) adults. The above results not only opened a potential prospect for applications of Rhododendrons in the prevention and control of insects in stored products, but also provide a basis for the comprehensive utilization of the rich natural Rhododendron plant resources.

“…Elsholtzia stauntonii is aromatic and its essential oils show insecticidal activity against certain pests of stored products ( Lv et al, 2012 ). Consequently, E. stauntonii is used in novel biological insecticides ( Liang et al, 2021 ). With its dense flowers, late flowering and bright colors, E. stauntonii is a popular bedding plant cultivated in public gardens and a wild nectar plant ( Tian et al, 2007 ).…”

Genetic Diversity Study on Geographical Populations of the Multipurpose Species Elsholtzia stauntonii Using Transferable Microsatellite Markers

Elsholtzia stauntonii Benth. (Lamiaceae) is an economically important ornamental, medicinal and aromatic plant species. To meet the increasing market demand for E. stauntonii, it is necessary to assess genetic diversity within the species to accelerate the process of genetic improvement. Analysis of the transferability of simple sequence repeat (SSR) markers from related species or genera is a fast and economical method to evaluate diversity, and can ensure the availability of molecular markers in crops with limited genomic resources. In this study, the cross-genera transferability of 497 SSR markers selected from other members of the Lamiaceae (Salvia L., Perilla L., Mentha L., Hyptis Jacq., Leonurus L., Pogostemon Desf., Rosmarinus L., and Scutella L.) to E. stauntonii was 9.05% (45 primers). Among the 45 transferable markers, 10 markers revealed relatively high polymorphism in E. stauntonii. The genetic variation among 825 individuals from 18 natural populations of E. stauntonii in Hebei Province of China was analyzed using the 10 polymorphic SSR markers. On the basis of the SSR data, the average number of alleles (NA), expected heterozygosity (HE), and Shannon’s information index (I) of the 10 primers pairs were 7.000, 0.478, and 0.688, respectively. Lower gene flow (Nm = 1.252) and high genetic differentiation (Fst = 0.181) were detected in the populations. Analysis of molecular variance (AMOVA) revealed that most of the variation (81.47%) was within the populations. Integrating the results of STRUCTURE, UPGMA (Unweighted Pair Group Method with Arithmetic Mean) clustering, and principal coordinate analysis, the 825 samples were grouped into two clusters associated with geographical provenance (southwestern and northeastern regions), which was consistent with the results of a Mantel test (r = 0.56, p < 0.001). Overall, SSR markers developed in related genera were effective to study the genetic structure and genetic diversity in geographical populations of E. stauntonii. The results provide a theoretical basis for conservation of genetic resources, genetic improvement, and construction of a core collection for E. stauntonii.
