Physical and chemical traits affecting the oviposition preference of honeysuckle geometrid, Heterolocha jinyinhuaphaga Chu among honeysuckle varieties

Oviposition preference is an important aspect of insect reproduction, females are able to evaluate the nutritional and structural properties of a plant and normally oviposit on the plant with suitable characteristics, thereby allowing their offspring to feed on a high-quality food source to enhance the offspring’s survival rate. Understanding of the host plant oviposition preferences of phytophagous insects may help to develop insect-resistant cultivars for use in integrated pest management. In this study, we investigated the physical and chemical traits that affect the oviposition preference of Heterolocha jinyinhuaphaga Chu among different honeysuckle varieties (wild variety, Jiufeng 1, Xiangshui 1, and Xiangshui 2) under laboratory conditions. The oviposition preference of H. jinyinhuaphaga differed among the four host plant varieties, with both oviposition quantity and oviposition percentage orders being wild variety > Jiufeng 1 > Xiangshui 2 > Xiangshui 1. Taxis response test using the Y-tube olfactometer obtained similar results, showing the response percentages of 91.67%, 87.47%, 81.78%, and 78.36% for the wild variety, Jiufeng 1, Xiangshui 2, and Xiangshui 1, respectively, compared with the air control. Correlation analysis indicated that both oviposition quantity and oviposition percentage by H. jinyinhuaphaga on the four host varieties were positively correlated with the soluble sugar content, protein content, total flavonoid content, and chlorogenic acid content of leaves, but negatively correlated with the hair density, hair length, water content, and fat content of leaves. Further path analysis indicated that protein content had the main effect on the oviposition quantity by H. jinyinhuaphaga. These results provide an important basis for breeding and developing insect-resistant honeysuckle varieties.

Analysis of Flower Color Variations at Different Developmental Stages in Two Honeysuckle (Lonicera Japonica Thunb.) Cultivars

Lonicera japonica Thunb., known as Japanese honeysuckle or golden-and-silver honeysuckle, belongs to the honeysuckle family and is native to eastern Asia, including China, Japan, and Korea. Microscopy, spectrophotometry, colorimetry, and the Royal Horticulture Society of Colorimetric Card (RHSCC) were used to compare and analyze the pigment distribution, content, and color variations in the Yujin 2 and Damaohua cultivars at different developmental stages. There were notable differences in the corolla color and the cross-section color between different developmental stages and different varieties. The lightness (L*), redness (a*), and yellowness (b*) values were calculated for each period for the two cultivars to observe variation trends. The chlorophyll content in the corollas of both cultivars showed declining trends with different rates. The chlorophyll content decreased rapidly from the young period to the two white period, and changed gradually from the two white period to the golden period. Moreover, the carotenoid content declined slightly from the young period to the silver period and rose sharply during the golden period. The ratio of these two pigment contents increased dramatically during the golden period: by 11.51 and 6.53 times in ‘Yujin 2’ and ‘Damaohua’, respectively. There were significant differences in corolla color, cross-section color, and the content of three pigments between the two varieties of honeysuckle. distribution and variation of pigments were the key factors affecting the flower color of honeysuckle. This study provides a basis for the identification and breeding of honeysuckle varieties and lays a foundation for further studies on the function and molecular mechanisms of pigments.

Comparative analysis of the polyphenols profiles and the antioxidant and cytotoxicity properties of various blue honeysuckle varieties

Abstract The polyphenol profile, antioxidant activity (particularly peroxyl radical-scavenging capacity (PSC) and cellular antioxidant activity (CAA)) and cytotoxicity of extracts from seven varieties of blue honeysuckle were compared in this study. Moreover, an analysis of correlations between individual polyphenol profiles and antioxidant activities was also conducted. Seventeen components were found in the investigated blue honeysuckle extracts, with anthocyanins being the prominent bioactive components among polyphenols. Fruit peel contained higher concentrations of individual anthocyanins compared to the fruit pulp. Beilei blue honeysuckle had the highest antioxidant activity. Correlation analysis showed that antioxidant activity values were highly associated with cyanidin-3-glucoside levels. Blue honeysuckle extracts were not cytotoxic over the range of doses tested. Among the varieties analyzed, Beilei possessed the highest antioxidant properties and was found to be the most appropriate source of natural antioxidants.

Viral Diseases and Rehabilitation of Honeysuckle (Lonicera caerulea L.) Plants

The prevalence of viruses in honeysuckle plants depends on the location of the plantation and the variety composition. TBRV virus had the maximal prevalence (28–60%) in most blue-berried honeysuckle stands. Prevalence of the ArMV virus ranged from 0 to 26%, that of the RpRSV virus ranged from 6 to 17%, and that of the SLRSV virus ranged from 7 to 25%. Most varieties of honeysuckle (67%) were infected with a complex of viruses, whereas no viruses were detected in certain varieties. The varieties produced at the Lisavenko Research Institute for Selection and Seedage had a higher degree of viral infection than those produced at the All-Russia Vavilov Research Institute of Plant Breeding. The viruses found in blue-berried honeysuckle plants were mostly in the latent form, but green leaf mottle and interstitial chlorosis were observed on individual bushes from a number of varieties. A tendency for virus infection accumulation with the extension of plant life was observed. TBRV and SLRSV transmission through seeds was registered, which is indicative of the need for improvement of the hybrid forms involved in the breeding process. The duration of dry air thermotherapy of honeysuckle plants should not exceed 30–45 days. Combined use of thermotherapy and meristem culture provided for an 80% yield of healthy plants.
