Apis Cerana Indica

Bees are responsible for more than 50% of all successful pollination. The pollination efficiency of Apis cerana indica was studied in Eggplant, Solanum melongena. The Apis cerana indica was found to spend 20 sec./flower/visit (20 ± 1.58). The amount of pollen depleted by Apis cerana indica was 563 pollengrains/insect visit (562.8 ± 34.89) and pollen deposition was 197 pollen grains/insect visit (196.8 ± 19.31).Pollen depletion and deposition by Apis cerana indica were more during 0800-1000 hrs. The peak activity of bees was recorded at 0900-1100 hrs when the temperature ranged from 28-32oC and humidity ranged from58-73%. The diurnal activity Apis cerana indica showed a significant positive correlation with temperature and negative correlation with humidity. These results showed Apis cerana indica is one of the efficient pollinators for Solanum melongena. The importance of Apis cerana indica colony for the improvement ofagriculture is also be discussed.

Different pollinators exhibit different adaptability to plants. Here, we compared the performance in visiting frequency and pollination efficiency among three bee pollinators (Bombus terrestris, Apis cerana, and Apis mellifera) on greenhouse-grown northern highbush ‘Bluecrop’ blueberry plants and evaluate their effects on yield and fruit quality. Our results indicated that the duration of daily flower-visiting of B. terrestris was 24 and 64 minutes longer than that of A. cerana and A. mellifera, respectively, and the visiting time of a single flower for B. terrestris was substantially shorter than the other two bee species, and pollen deposition on the stigma from single visit by B. terrestris was twice and three times that of A. cerana and A. mellifera, respectively. The yield of individual plants pollinated by B. terrestris showed an increase of 11.4% and 20.0% compared with the plants pollinated by A. cerana and A. mellifera, respectively, with the rate of Grade I fruit (>18 mm diameter) reaching 50.8%, compared with 32.9% and 22.5% for A. cerana and A. mellifera groups, respectively. Moreover, the early-to-midseason yield of plants pollinated by B. terrestris was higher, and the ripening time was 3 to 4 days earlier. An artificial pollination experiment demonstrated that seed set of high (≈300), medium (90–110), and low (20–30) pollination amounts were 43.0%, 42.5%, and 10.5%, respectively, and the corresponding mean weights of single fruits (related to the seed number inside) were 2.8, 2.7, and 1.2 g, respectively. The highly efficient pollination of B. terrestris was attributed to its behavior of buzz-pollination. Therefore, it is preferential for pollination of ‘Bluecrop’ blueberry in the greenhouse.

A study was conducted to investigate the diurnal activity patterns of hymenopteran pollinators in culinary melon and the dynamics of hymenopteran pollinators of five selected cucurbitaceous vegetables viz.,culinary melon, bitter gourd, pumpkin and ridge gourd in 34 locations of Kerala from 06:00 h to 18:00 h with a cone type hand net. The study revealed that Apis cerana indica was dominant in culinary melon, pumpkin and ridgegourd and Tetragonula travancorica was dominant in bitter gourd and ash gourd, A. cerana indica, T. travancorica and Halictus sp. recorded highest foraging speed during 10:00 h to 11:00 h; Ceratina hieroglyphica and Lasioglossum sp. recorded highest foraging speed during 09:00-10:00 h; T. travancorica, C. hieroglyphica and Lasioglossum sp. recorded maximum foraging rate during 10:00 h to 11:00 h; A. cerana indica and Halictus sp. recorded highest foraging rate during 11:00-12:00 h and 09:00-10:00 h.

Abstract The hypopharyngeal gland (HPG) is the principal organ of protein synthesis in honey bees. It is involved in larval rearing. We examined the fresh head weight, HPG acini diameter, and HPG protein content in worker bees engaged in different tasks and under brood and broodless conditions. Scanning electron microscopy revealed that the HPG acini diameter of worker bees was related to their task. The highest HPG volume was found in nurse bees, and the volume regressed when the task changed from guarding to foraging. The fresh head weight was positively correlated with HPG acini diameter. Although, there was no positive correlation between HPG acini diameter and protein concentration, the glandular protein concentration increased progressively in nurse bees and declined in guard and forager bees. Histochemistry revealed similar results. Despite displaying significantly larger glands, guard bee protein secretion was similar to that of the foragers. Brooding had a significant effect on HPG activity. Only worker bees from the colony with an intact brood showed elevated rates of protein synthesis; thus, it is possible that a signal was emitted by the brood, which stimulated protein synthesis in the HPG. However, the size of the HPG was similar in both brood and broodless conditions.

Wolbachia is a group of cytoplasmically inherited bacteria that can cause reproductive alterations in arthropods including parthenogenesis, reproductive incompatibility and feminization of genetic males. Wolbachia are found in a well studied group of insects, but there is a lack of data on their distribution. Workers of the honeybee sub species Apis cerana indica, collected from different parts of Karnataka, India were screened by PCR for Wolbachia, because this endosymbiont has been implicated in causing thelytoky in other Hymenoptera. In the present communication, we report the absence of Wolbachia endosymbiont in the workers of honeybee collected from different geographic locations of Karnataka using Wolbachia specific 16S rDNA polymerase chain reaction enzymes.DOI: http://dx.doi.org/10.3126/ijls.v5i1.5230 International Journal of Life Sciences Vol.5(1) 2011 19-24

Pollen analysis of 8 multifloral honey samples collected from 4 locations of Godavari, Lalitpur district, Nepal was performed using Scanning Electron Microscope (SEM). In this investigation, a wide range of foraging plant sources for Apis cerana honey bees was identified which demonstrates the adequate potential for expanding and sustaining beekeeping in this area. The palynological assemblage of a total of 44 species of pollen flora representing 28 families was identified to the generic and some up to species level. Some of the pollen grains identified to only families, belong to Acanthaceae, Apiaceae, Araliaceae, Chenopodiaceae, Compositae, Lamiaceae, Loranthaceae, Meliaceae, Poaceae, Rosaceae, Rutaceae and Pteridaceae. The pollen assemblages in honeys were mostly belonging to angiosperms while the gymnosperm pollen was completely absent. One pteridophyte spore belonging to family Pteridaceae recovered. In this paper the morphology of the pollen grains based on SEM observation are described and the importance of the systematic documentation of various bee flora are discussed.J. Nat. Hist. Mus.
