“…A mathematic model developed by Cresswell (2010) was used to evaluate the gene flow in experimental fields of safflower pollinated by honeybee A. mellifera and Bombus spp. This model estimated that the maximum feasible level of bee-mediated, field-to-field gene flow ranged between 0.05% and 0.005% of seed set (95% upper confidence intervals of 0.23% and 0.023%), depending on the composition of the bee fauna.…”

“…Mathematical models (Baker & Preston, 2003;Cresswell, 2010), empirics (Weekes et al, 2005;Damgaard & Kjellsson, 2005;Gustafson et al, 2006) and deterministic (Colbach et al, 2001;2004;Walklate et al, 2004) that simulate the gene flow in fields of trangenic and conventional plants are found in literature. However, each model has its advantages and disadvantages.…”

“…In an insect-pollinated crop, gene flow occurs when pollinator moves between fields and cross-pollinate flowers with 'foreign' pollen (Cresswell, 2010). The gene flow via pollen by biological agents is a primordial factor in cross-pollination rates.…”

“…There have been several studies done on the interactions between pollinator insects and oilseed plants, especially on rapeseed (Brassica napus L.) (Free and Nuttall, 1968;Steffan-Dewenter, 2003;Bommarco et al, 2012;Lindström et al, 2016) and sunflower (Helianthus annuus L.) (Delaude et al, 1979;Degrandi-Hoffman and Chambers, 2006;Öz et al, 2009;Said et al, 2017). Although safflower is an important source of edible oil, and is also important for biodiesel production in drought conditions (Emongor, 2010), the number and extent of studies that have focused on the pollination ecology of safflower (Boch, 1961;Eckert, 1962;Rubis et al, 1966;Barbier et al, 1976;Langridge and Goodman, 1980;Deshmukh et al,1985;Singh et al, 2000;Abrol, 2009;Cresswell, 2010;Nabloussi et al, 2013;Navatha and Sreedevi, 2015;) is still insufficient.…”

Carthamus tinctorius L. (safflower) is a drought-tolerant plant that has been cultivated for its oil, carthamin pigment, and edible parts. Seed production by safflower is related to its pollination success. The aim of this study was to evaluate the effects of Apis mellifera L. (honey bee) and Bombus terrestris L. (bumble bee) pollination on safflower seed quality. Experiments with five treatments were prepared, four of which consisted of cages with either honey bees, bumble bees, or honey bees and bumble bees together in them, or without any insects, plus one open-pollinated plot treatment. To determine seed quality in the different treatments, the total seed yield, 1000 grain weight of seeds, number of seeds per capitulum, total oil content, fatty acid composition, and total oil yield in each treatment was determined. Total seed and oil yield was increased with bee pollination, whereas no significant difference was found in the total oil content and 1000 grain weight of seeds among treatments. Significant differences were observed among treatments in their seeds’ fatty acid compositions, specifically in their content of oleic acid, linoleic acid, and linolenic acid. As a result, it was found that pollination by bees can positively affect the seed characteristics of safflower, while also increasing the total seed yield. We thus recommend using commercial bees in the cultivation of safflower.

“…Syrphidae and Calliphoridae), are presumed to be their key pollinators ( Free 1993 ). Large insects, particularly bees, are also considered key vectors for pollen transport between crop fields that can result in unwanted cross pollination ( Osborne et al 1999 ; Cresswell and Osborne 2004 ; Cresswell and Hoyle 2006 ; Cresswell 2010 ). However, small arthropods (< 3mm body width) that are often overlooked as potential pollinators, can be very abundant within many crops ( Lewis 1973 ; Mound 2004 ), e.g.…”

Onion, Allium cepa L. (Asparagales: Amaryllidaceae), crop fields grown for seed production require arthropod pollination for adequate seed yield. Although many arthropod species visit A. cepa flowers, for most there is little information on their role as pollinators. Small flower visiting arthropods (body width < 3 mm) in particular are rarely assessed. A survey of eight flowering commercial A. cepa seed fields in the North and South Islands of New Zealand using window traps revealed that small arthropods were highly abundant among all except one field. Insects belonging to the orders Diptera and Thysanoptera were the most abundant and Hymenoptera, Collembola, Psocoptera, Hemiptera, and Coleoptera were also present. To test whether small arthropods might contribute to pollination, seed sets from umbels caged within 3 mm diameter mesh cages were compared with similarly caged, hand-pollinated umbels and uncaged umbels. Caged umbels that were not hand-pollinated set significantly fewer seeds (average eight seeds/umbel, n = 10) than caged hand-pollinated umbels (average 146 seeds/umbel) and uncaged umbels (average 481 seeds/umbel). Moreover, sticky traps placed on umbels within cages captured similar numbers of small arthropods as sticky traps placed on uncaged umbels, suggesting cages did not inhibit the movement of small arthropods to umbels. Therefore, despite the high abundance of small arthropods within fields, evidence to support their role as significant pollinators of commercial A. cepa seed crops was not found.
