INTERNATIONAL JOURNAL OF PLANT PROTECTION, 2016
Among different flower visitors of coriander, Apis florea was the predominant visitor followed by A. dorsata and A. cerana. The activity of flower visitors were more at 11 00 h followed by at 10 00 h. Among different bee species, the activity of A. florea was reported from 09 00 to 12 00 h and from 16 00 to 18 00 h with maximum activity at 10 00 h. The activity of A. dorsata was observed from 09 00 h to 12 00 h and from 15 00 h to 18 00 h with maximum activity at 11 00 h. The studies on the effect of bee pollination on yield of coriander was undertaken at Spices Research Station, College Farm, Navsari Agricultural University, Navsari during Rabi 2010-11 by confining A. cerana bees in plots of coriander variety DH 5 in cage condition i.e. Bee pollination (BP) which was compared with open pollination (OP) and pollination without insects (PWI). The number of filled seeds/umbel was significantly higher in BP (54.03) followed by OP (49.62) and lowest in PWI (27.40). The per cent seed set was significantly higher in BP (69.51 %) followed by OP (62.21 %) and minimum in PWI (54.89 %). Highest yield was obtained in BP (14.57 q/ha) which was at par with OP (14.26 q/ha) but significantly higher than PWI (11.66 q/ha). The 1000 seed weight was also highest in BP (5.68 g) which was statistically at par with OP (5.28 g) but significantly higher than PWI (4.09 g). The germination per cent of seed was also significantly higher in BP (75.91 %) which was followed by OP (73.09 %) and the lowest in PWI (62.76 %). The results indicated that bees have significant role in enhancing yield and quality in terms of seed weight and germination percentage of coriander.

Studies on spatial distribution, foraging behaviour of pollinators and effect of different modesof pollination on yield of coriander (Coriandrum sativum) were undertaken at Karnal (Haryana).Coriander flowers were visited by 34 species of insects belonging to 18 families and 8 orders.Apoidea (35.9%), diptera (47.8%) and other hymenoptera (13.2%) were the three major groupscomprising 96.9% of the total visitors. Italian honey bee, Apis mellifera was the most prominentspecies (31.1%) followed by Episyrphus balteatus (19.2%) and unidentified Hymenoptera species(10.2%). Honey bees foraged both for nectar and pollen whereas, dipterans and other speciesfor nectar alone. A. mellifera started foraging early at 09.05 h, peaked from 11.00 to 16.00 hand declined drastically thereafter. A. dorsata peaked at 11.00 h and was not recorded after14.00 h. A. cerana population peaked from 10.00 to 14.00 h and was not recorded after 15.00h. The syrphid and other dipteran flies were present throughout th...
Foraging behaviour of honey bees on coriander, 2019
A field observation was undertaken at Rajmohini Devi College of Agriculture and Research Station, Ambikapur of Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during 2017-18 to study the foraging activity of various honey bee species on different time hours on coriander bloom. Various honey bee species i.e. Apis cerana, Apis mellifera, and Apis dorsata were observed and the Apis dorsata was found dominant bee species. Apis indica was noticed maximum population at 1200hrs (6.77 bees/5min/m2) followed by at 1000hrs (5.16 bees/5min/m2) however the lowest population was recorded at 0800hrs (1.77 bees/5min/m2). Apis mellifera population was recorded highest at 1200hrs (6.57 bees/5min/m2) followed by at 1000hrs (4.97 bees/5min/m2) however, lowest population was found at 0800hrs (1.85 bees/5min/m2). Apis dorsata population was found foraging maximum at 1200hrs (7.47 bees/5min/m2) followed by at 1000hrs (6.5 bees/5min/m2) and the lowest was recorded at 1600hrs (2.2 bees/5min/m2).

2010
Investigations were carried out to evaluate the “Influence of certain plant products on the insect pollinators of coriander” at Rajasthan College of Agriculture, Udaipur, during rabi 2008-09. The treatments comprised: Pongamia glabra Vent (seed oil – 1 %), Azadirachta indica A. Juss (seed kernel extract 5%), formulated neem product (Achook 0.8%), Azadirachta indica (seed oil 1%), Azadirachta indica (leaf extract 10%) replicated 4 times. Reduction in pollinator population was estimated one day after application of the botanicals; whereas, 3 and 5 days after the treatment the mean percentage increase or decrease in the pollinator abundance over control was computed. The plant origin insecticides evinced a decrease in pollinator intensity ranging from (-) 14.52 to (-) 25.06 per cent. The maximum reduction of insect pollinators (25.06%) was recorded from plots treated with neem seed oil (1%). Three days after the treatment the percentage of visiting insect pollinators did not change in ...
To regulate the reaction of honeybee (Apis mellifera L.) pollinator on cucumber seed yield, experimental trials were demonstrated at BARI, Chakwal, in complete randomized block design by using different method of comparison (open pollinated and caged method) to determine the contribution of honeybees in pollination of cucumber crop. Seven parameters were assessed including i. Pollinator diversity (The result revealed that maximum visitation frequency of pollinator was carried out by Apis mellifera (71.6 %) and minimum (6.7%) by Dipteran Episyrphus balteatus), ii. Pollinators density (the results showed that cucumber crop was visited by five insect species of three orders of Hymenoptera, Diptera and Coleopteran at three different time intervals 1000-1100 hrs, 1200-1300 hrs, 144-1500 hrs respectively. Average visit of insects on cucumber flower per 5 minutes interval per plant contributed by Apis mellifera 6.8, 5.4, 3.7 respectively was found to be significantly most abundant and least contribution of syrphus beetle was observed 0.45, 0.68 and 0.76 respectively. iii. Flower attractiveness i.e. results revealed that Insects' visitor occurrence was unswervingly linked to the advancement of C. sativa blooming. The association of C. sativa flowers and accepted forger bees amount during the flowering retro was determined progressive. (the profusion of nutrition properties offered by C. sativus improved the flower attraction and subsequently bee fertilization lead to the high seed productivity), iv. Pollination efficacy determine on the basis of Yield parameters including a-mean weight of fruits b-length of fruit (cm), c-fruit diameter(cm), d-seed weight and eno. of seed per fruit indicated that (Pollination efficacy by all pollinators in open pollinated method is significantly higher than caged method) that leads to higher yield.
Role of Honeybee (Apis mellifera) in Enhancing Yield of Mustard in Humid Region of Rajasthan, India
Mustard (Brassica spp.), family cruciferae are the major oilseed crop grow throughout India for edible oil. It is an open pollinated crop and honeybees are effective pollinators for open pollinated crops because of a lot of nectar and pollens are available on the flowers of mustard. The studies were conducted during rabi 2013-14 and 2014-15 at ARS, Kota to enhance the yield of mustard through honey bee pollinator. Mustard variety “Bio-902” was grown following all recommended agronomic practices without spraying through the crop season. The colonies of honeybee (Apis mellifera) were placed in cage measuring 10X10 sq. meters before the initiation of flowering. The present study contained three pollination treatments viz., Plants caged Pollinator Exclusion (PE), Plants caged with bee hive (BP) and Plants kept open to all pollinators (OP). The comparative data pertaining to modes of pollination in mustard crop revealed that highest values of mean no. of siliqua/plant (186.44), no. of seeds/ siliqua (13.82) and seed yield (20.54 q/ha) were obtained from OP followed by BP and it was recorded lowest in PE. The introduction of honeybees in agricultural crops plays a vital role in pollination which in turn resulted in higher production of seed yield as well as honey production.
Role of insect pollinators in pollination of seed spices-A review
Review Article, 2015
A large population of insects visits several seed spices and other crops right from initiation of flowering to harvesting of crops for foraging in seed spices coriander and fennel normally received 25 and 24 floral visitors, respectively in semi-arid and arid conditions of Rajasthan and honeybees are to be considered as primary pollinators of all seed spice crops. Among honeybee species, Apis florea contributed greatest percentage followed by A. mellifera and A. dorsata for pollination. Beekeeping with A. mellifera is profitable because of huge bee flora is available in Indian continent round the year, provide nectar and pollen to the honeybees. The manmade pollination with honeybees, adequate knowledge about bee flora, bee management, pollinator's management and managed pollination are the common practices to enhance the yield and quality in seed spices (highly cross pollinated) and promote beekeeping industry to produce good quality honey. In view of the great role of honey bees in pollination of cross pollinated crops especially seed spices, there is a need to popularize bee-cultivation with A. mellifera in the country.
An On farm trial was conducted at KrishiVigyan Kendra, Vaishali, Bihar to study the impact of planned honeybee pollination on the seed production and quality of Cauliflower seeds as well as pollination behavior of Apis mellifera. More number of bees were found visiting the crop under net house condition (6.05 , 5.35, 5.05 bees/plant at all the three locations of traditionally seed producing Hariharpur, Rajapakar and Chakwaravillages of Vaishali district.Bees in the open conditions were found to spend less time on flower as compared to the net house conditions. Honeybees played an important role in enhancing the seed production of cauliflower at all location under study. Planned honeybee pollination was found to result maximum impact on the seed production seeds/pod in the range of 15.50-19.10 seeds/pod in net pollination as compared to 13.60-17.20 seeds/pod in open condition. Similarly, average 1000 seed wt. in net pollinated condition was 3.30-4.19 gm whereas 3.00-3.97 gm in open field condition, and the yield in net condition was in range 534-637 kg/ha with additional income of 14 to 17 lakh rupees per hectare. INTRODUCTION Agriculture is the basis of the livelihood of over 80 percent of the rural population in Bihar (). However, most of the farmers are marginal or small land-holding families, cultivating less than one hectare of land. The small and marginal farmers of Bihar are increasingly taking up vegetable cultivation to improve their income (). In Vaishali district of Bihar the vegetable based farming system among different category of farmers is most prevalent (). The farmers here traditionally produce seeds of local variety of early cauliflower Brassica oleracea under open field situation.Low seed yield and quality due to inadequate pollination is major problem of cauliflower seed producing farmers. Inadequate pollination in crops is due to several factors and the most important of which includes lack of adequate number and diversity of pollinators. All possible ways of increasing the sustainable productivity and carrying capacity of the farming systems in order to improve the livelihoods of marginal households should be explored (). Amongst several factors attributing to increase productivity, the most important of which include the number of bee pollinators. Research has shown that pollination by honey bees increases fruit set, enhances fruit quality and reduces fruit drop in apple (), peach, plum, citrus, kiwi and strawberry (). Bee pollination does not only increase the fruit set but also reduced fruit drop in apple, peach, plum and citrus (). The experiment conducted AICP on Honeybee

Pollination is an essential process in the production of seed plants, it results in a genetically diverse production of offspring and its role is not well understood and appreciated in the local farming system. This study was conducted to evaluate the effect of honeybees pollination on Black cumin seed yield and yield related parameters at Sinana Agricultural Research center at on-station. The study had three experiment; these includes plots caged with honeybees (T1), plots caged without honeybees (T2) and open pollinated plots (T3). All collected data were analyzed using One-way-Analysis of Variance (ANOVA). In the study seven species of insects were identified as Nigella sativa visitors or pollinators with the most frequent visitors were honeybees at 11:30 am time and minimum at 3:00 pm on open pollinated plot. There were no significant different (P>0.05) on Date of blooming, Date of flowering, Flowering period, Primary and secondary branches among the three treatments. Whereas, there were a significant difference (P<0.05) on shading time, Number of capsule, Thousand kernel and total seed yield per hector. In general the present study showed that the highest seed yield/hector was achieved from crops caged with honeybees (20.20Qt/ha) and followed by open pollinated crop (17.54Qt/ha). The result also revealed that about 30.84% of seed yield advantage of Nigella sativa pollinated by honeybees over control/un pollinated by any insect. From this result it was concluded that visits of honeybees at flowering time of Nigella sativa have very helpful in boosting seed yield and yield related components of this crop.
