“…There was evidence in support of link between insect pollinator visitation rates and yield gains in oilseed rape (Hypothesis 1), a finding also found in several other studies (Bommarco et al, 2012;Stanley et al, 2013;Bartomeus et al, 2014). Over the range of insect pollinator visitation rates identified we show that yield gains in oilseed rape attributable to insect pollinators were equivalent to c. 0.4 t ha À1 .…”

“…Empirical studies have shown that wild bees occurring near crop areas are important pollinators (Brittain et al, 2013;Garibaldi et al, 2013;Rader et al, 2012;Rogers et al, 2014;Slaa et al, 2006;Stanley et al, 2013). In the present study, we demonstrated that the bees A. mellifera, Halictus sp., Plebeia sp., T. spinipes, and T. pallens were effective pollinators of Cucumis spp.…”

a b s t r a c tAlthough bees are important pollinators in many ecosystems worldwide, studies on bee diversity and their contribution to pollination of commercial plants in the Brazilian Cerrado (savannah-like biome) are scarce. The Cerrado biome covers approximately 23% of Brazil and is one of the world's most important agricultural frontiers. Here, we conducted field experiments in the Brazilian Cerrado to evaluate the diversity of bees, their foraging behaviors and flower visiting periods, and their potential contribution to the performance of six melon (Cucumis melo L.) cultivars. Five bee species (Apis mellifera, Halictus sp., Plebeia sp., Trigona pallens, and T. spinipes) were recorded visiting both male and hermaphrodite flower types of all C. melo cultivars. Whereas A. mellifera showed two peaks of flower visitation (an intense first one between 8:00 a.m. and 11:00 a.m. and a second less intense one after 4:00 p.m.), all other bee species visited the C. melo flowers only in the morning, with intensities and visitation peaks similar to those of A. mellifera. All of these bees collected nectar and pollen. Our results also indicated a moderate correlation between the intensity of bee visitation and fruit weight, demonstrating that all of these bees had the potential to pollinate C. melo and to influence its productivity. Except for the cultivar 'Hibrix', all the other cultivars showed economic feasibility and produced fruits of marketable sizes, with an estimated yield (over 25 tons/ha) in the range registered in other Brazilian regions.

“…Pollination of B. napus occurs through a combination of wind and insect visitors with considerable autogamy apparent. Field and cage studies have shown positive effects of insect pollination on pod set and seed set (Stanley et al, 2013), with associated benefits to the yield and quality of production (Bommarco et al, 2012).…”

SUMMARYA study of insect pollinators and their impact on canola yield was conducted during the 2013/2014 and 2014/2015 growing seasons. The study was carried out at an experimental farm, Faculty of Agriculture, Suez Canal University, Ismailia. The results revealed that 21 species of insect pollinators belonging to 14 families under four orders visited canola flowers. The abundance of Hymenoptera insects reached the maximum of 67.90%, followed by Diptera 14.97%, Coleoptera 13.61%, then Lepidoptera 2.26% as average of both seasons. In open pollination, Colletes lacunatus had the maximum percent abundance in the two seasons (30.45 and 29.34%, respectively) followed by Apis mellifera (12.34 and 17.73%, respectively), compared to other bees and different pollinators. Peaks of foraging activity of both C. lacunatus and A. mellifera were mainly observed from 1:00 to 3:00 pm and they corresponded to the number of flowering plants. Open pollination increased the number of pods per plant, seeds per pod, weight of 1000 seeds, yield per plant, yield per feddan (1 fed = 0.42 ha) and seed germination, compared to non-open pollination.
