Identification of two thaumatin-like proteins (TLPs) in the pollination drop of hybrid yew that may play a role in pathogen defence during pollen collection

An experiment was conducted to determine the foraging behavior of Apis mellifera L. and Apis cerana F. in rapeseed under cage condition in Chitwan, Nepal during 2012-2013. This experiment showed that Apis cerana F. foraged extra 42 minute per day as compared to Apis mellifera L. Apis cerana F. were more attracted to nectar, whereas Apis mellifera L. were more attracted to pollen collection throughout the day. The activities, in into hives and out from hives, for both species were recorded more at 2:00 pm and least at 8:00 am. The highest in-out were observed at 2:00 pm on both species as Apis mellifera L. 44.33 bees entered into hives and 49.66 bees went out of hives, whereas lower number of Apis cerana F. 43.66 bees entered into hives and 48.16 bees were out of hives. Apis mellifera L. collect 1.22:1 and 0.41:1 pollen nectar ratio at 10:00 am and 4:00 am whereas at same hours Apis cerana collect 1.16:1 and 0.30:1 pollen nectar ratio. Apis cerana F. foraged significantly higher number of rapeseed flowers and plants as compared to Apis mellifera L. under caged condition. It shows that Apis cerana F. was more efficient pollinator as compared to Apis mellifera L. under caged condition.

Selection Of

The purpose of this work was to research the morphological characteristics of monofloral bee pollen obtained from Brassica napus L. The formulated goals were: determine the period of bee pollen receiving; implement the selection of bee pollen samples during blooming period of species; establish the monoflorality ratio of the total pollen collection; explore the morphometric indicators of bee pollen by the parameters of pollen lump, shaping level and weight. Bee pollen collection was carried out in Skvyra district of Kyiv region from local population of Apis mellifera L. families. Morphometric measurements were performed in the Institute of Biodiversity Conservation and Biosafety, Slovak University of Agriculture in Nitra. Here were determined the amount of bee pollen per one day brought by one family: from 27.04 to 03.05.16 is 50.8 ± 2.25 g; from 04.05 to 06.05.16 – 100.0 ± 3.33 g; from 07.05 to 17.05.16 – 270.7 ± 11.79 g; from 18.05 to 22.05.16 – 100.5 ± 3.028 g; from 23.05 – 25.05.16 – 39.8 ± 2.74 g. Here were defined the morphological parameters of bee pollen lump from B. napus: length is in the range from 3.40 ± 0.061 mm to 3.66 ± 0.048 mm; width is in the range from 2.88 ± 0.059 mm to 3.26 ± 0.067 mm; weight is in the range from 8.65 ± 0.317 mg to 11.31 ± 0.241 mg; shaping level of bee pollen is in the range 4.62 – 4.96 points. The total monoflorality ratio constitutes from 79.94 ± 0.619 % to 98.00 ± 0.202 %. The obtained results confirmed that the activity of bee flying depends on the blooming period and intensity of the nectar secretion, on the collection of protein feed from B. napus. Pollen lumps from Brassica napus L. bee pollen were large, dense, regular shape without splits, which specified the possibility of its use for the producing on a commercial scale.

Pollen Loads

In May, July and September pollen loads samples were collected from 20 honeybee colonies, during 4 days at fixed hours. The pollen loads were classified into botanical taxons. Pollen loads of every examined taxon were collected during the whole day. The daily dynamics of pollen collection depends more on time of the day than temperature.
