Asian Honeybee

In Pakistan, Apis cerana, the Asian honeybee, has been used for honey production and pollination services. However, its genomic makeup and phylogenetic relationship with those in other countries are still unknown. We collected A. cerana samples from the main cerana-keeping region in Pakistan and performed whole genome sequencing. A total of 28 Gb of Illumina shotgun reads were generated, which were used to assemble the genome. The obtained genome assembly had a total length of 214 Mb, with a GC content of 32.77%. The assembly had a scaffold N50 of 2.85 Mb and a BUSCO completeness score of 99%, suggesting a remarkably complete genome sequence for A. cerana in Pakistan. A MAKER pipeline was employed to annotate the genome sequence, and a total of 11,864 protein-coding genes were identified. Of them, 6750 genes were assigned at least one GO term, and 8813 genes were annotated with at least one protein domain. Genome-scale phylogeny analysis indicated an unexpectedly close relationship between A. cerana in Pakistan and those in China, suggesting a potential human introduction of the species between the two countries. Our results will facilitate the genetic improvement and conservation of A. cerana in Pakistan.

Daily Activity Patterns

Camellia spp., which are self-incompatible plants, are some of the most important woody species producing edible oil in Southeast Asian countries. However, the demand for camellia oil currently exceeds the supply due to low product yields that have resulted from a decrease in pollination services. Although Camellia osmantha, C. vietnamensis, and C. oleifera are cultivated in South China, little is known about the correspondence between pollinator abundance and pollinator services for this plant genus. In this study, the diversity, daily activity patterns, and pollination effectiveness of insects visiting C. osmantha, C. vietnamensis and C. oleifera were investigated. A total of 24 species, belonging to four orders and 11 families, of visiting insects were identified. Apis cerana cerana Fabricius, Vespa bicolor Fabricius, V. velutina Lepeletier, V. ducalis Smith, and Phytomia zonata Fabricius were the dominant pollinators. The daily activity peaks of the five visiting insects were between 10:00 and 14:00, which may have been related to the pattern of floral resource production (particularly nectar). Cross-pollination by insects significantly increased the fruit production rates of C. osmantha, C. vietnamensis, and C. oleifera. Therefore, the wild bees and flies that pollinate wild and cultivated Camellia plants should be protected in South China.

Stroberi (Fragaria x ananassa Duch.) merupakan tanaman hortikultura yang penyerbukannya sebagian tergantung pada serangga. Studi dilaksanakan pada pertanaman stroberi di Ciwidey-Bandung, dengan tujuan untuk memperkirakan kontribusi dari serangga pengunjung bunga terhadap kesuksesan penyerbukan stroberi. Di dalam studi ini kontribusi tersebut dinilai dari kelimpahan spesies serangga pengunjung bunga dan durasi kunjungan pada bunga, serta efisiensi penyerbukan yang diukur dari jumlah akene yang berkembang, bobot, dan ukuran buah, serta waktu matang buah. Hasil studi menunjukkan terdapat empat spesies serangga pengunjung bunga stroberi yang paling umum dijumpai, yaitu dua lalat bunga Episyrphus balteatus (Deg.) (47,3%) dan Melanostoma sp. (33,8%); serta dua lebah Lasioglossum sp. (7,0%) dan Apis cerana Fabricius (5,3%). Durasi kunjungan pada setiap bunga oleh kelompok lalat bunga berlangsung 7,75–10,00 menit, sedangkan oleh kelompok lebah 0,25–0,79 menit. Buah stroberi yang berkembang dari bunga yang mendapat kunjungan tunggal oleh setiap spesies serangga menghasilkan buah dengan jumlah akene berkembang 1,6–1,8 kali lipat lebih banyak, bobot buah 1,8–2,3 kali lipat lebih berat, diameter buah 1,2–1,3 kali lipat lebih lebar, serta waktu matang buah 1–3 hari lebih singkat, dibandingkan dengan buah yang berasal dari bunga yang tidak dikunjungi serangga. Keberadaan lebah dan lalat bunga memberikan sumbangan yang penting terhadap penyerbukan pertanaman stroberi di Ciwidey. Temuan dari penelitian ini berimplikasi terhadap peningkatan hasil panen stroberi melalui pengelolaan serangga penyerbuk.

Work on going through the adaptation stage of rooted micro-stalks comes down to searching for new growth regulators and studying the influence of external conditions, which include, among other things, light effects. The data of 2018-2019 on the effect of growth regulators Siliplant, EcoFus and experimental LED phytoradiators on the adaptation of rooted micro-stalks of garden strawberries (Fragaria x ananassa duch) in vivo are presented. The object of research is rooted micro-stalks of garden strawberries of the Korona variety. It was revealed that, at the adaptation stage of rooted micro-stalks of strawberries, the most effective was the treatment of plants by spraying with Siliplant at a concentration of 1.0 ml/l and the combined treatment with Siliplant and EcoFus at concentrations of 0.5 ml/l: regardless of lighting, the survival rate averaged 99.4 - 99.7%, the leaf surface area increased significantly from 291.85 mm2 to 334.4 mm2. The number of normally developed leaves of strawberry microplants increased significantly after treatment with all preparations from 3.5 to 6.0, 5.8 and 6.5 pcs/plant, and a significant increase in the height of strawberry rosettes was facilitated by treatment with Siliplant and Siliplant together with EcoFus. Regardless of growth regulators, the most effective was the experimental LED phyto-irradiator with a changing spectrum, which contributed to an increase in leaf surface area, height of rosettes and the number of normally developed leaves in strawberry microplants. When illuminated with a flashing phytoradiator, these indicators are lower than in the control version, but not significantly. By the end of the rooting stage, all microplants of garden strawberries corresponded to GOST R 54051-2010.
