“…The pigeon pea were visited by insect pollinators' viz. Apis cerana, A. mellifera, A. dorsata and other pollinators like Xylocopa leucothorax, X. fenestrata, Polystis habrius, Vespa magnifica, Musca domestica, Monomorium indicum and Papilio demoleus (Rajkhowa and Deka, 2013).…”

The importance and impact of insect pollinators on pigeonpea productivity has been studied. Fourteen major insect pollinators/ visitors species were recorded during blooming stage, out of which 13 belong to the Hymenoptera. The productivity parameters viz., number of seed set/pod (3.53± 0.23), pod set (26.67± 1.43%) and productivity (1166.51± 6.26 kg/h) recorded from open pollination were observed to be significantly higher than pollinator exclusion.

“…Foraging intensity was recorded during the entire blooming period i.e., early, mid, peak and at late blooming periods as number of bees/m 2 /minute (Thangjam et al, 2018) [25] . A total number of visiting insects/m 2 of randomly selected crop area were counted for one minute in three replications as per the methods given by Amin et al, 2018 [1] .…”

The study was carried out on the foraging behavioral aspects which are either genetically influenced or are dependent on external factors on four horticultural crops viz., cabbage, Chinese cabbage, blueberry and peach at Bee Research Station, CSK HPKV, Palampur, Himachal Pradesh, India during 2019. The significantly highest foraging rate and foraging speed of Apis dorsata was registered as 11.76 and 9.91 respectively on four crops altogether. Apis cerana was the most predominant insect visitor with maximum foraging intensity as insects/m 2 /minute during peak bloom on cabbage (3.47) as well as on Chinese cabbage (3.61). While Apis dorsata was predominant pollinator on peach (6.67 insects/m 2 /minute) and blueberry (3.85 insects/m 2 /minute). This study would be helpful to beekeepers as it is very important to understand the behavior patterns represented by bees for better management aspects.

Niger,Guizotia abyssinica(L.f.), is an important oilseed crop widely grown in Ethiopia and India, but poor pollination is one of the major constraints in achieving the yield potential of the crop. Our aim was to understand better the pollination biology and role of flower insect visitors in reproduction success. Results indicated that full anthesis occured in the morning between 06.00 and 08.00 h and pollen dehiscence eight to eleven hours after anthesis. Stigma receptivity commenced nine hours after anthesis and lasted for the next 24 h. A total of eighteen insect species representing six families visited Niger flowers, and among these,Apis floreaandA. ceranawere dominant. The flowers were self-incompatible as there was no seed set upon the selfing of floret and selfing of capitulum. The maximum seed set (78.33±0.14%) was noticed when flowers were allowed for open pollination and the lowest was recorded when the whole plant was caged to exclude pollinator visits (0.33±0.67). The time spent byA. ceranaandA. floreawas 1.35±0.48 and 1.83±0.12 seconds per floret, respectively and 9.63±0.69 and 14.9±0.94 seconds per capitulum, respectively.A. ceranaandA. floreawere found to be more efficient pollinators ofG. abyssinica.Introducing bee colonies might greatly improve the yield, and it is also important to conserve bees in the vicinity ofG. abissynicafields during the flowering period. Hence, introducing bee colonies might greatly improve the yield of Niger.
