“…Therefore, we concluded that the length of the spines on upland cotton pollen was the primary factor responsible for the low packing efficiency of this pollen by honey bees. This conclusion is consistent with the collection of pollen from G. thurberi (Buchmann & Shipman 1990) and G. arborewii (Tanda & Goyal 1979) in the open because the pollen of these two diploid species have smaller spines than that of the tetraploid G.

“…Abebiosclm pollen was the largest grain in our study (155.7 p m ESD, Table I) and honey bees could not harvest it at all. In the open, honey bees collect pollen from Gossypiiriii tlrrirberi (Buchmann & Shipman 1990) and G. orboreurn (Tanda & Goyal 1979), both of which are diploid species with smaller pollen grains than those of the tetraploid G.

“…Tanda & Goyal (1979) reported that Apis niclliferi gathering pollen on cultivated G. orboreiim packed loads weighing on average 4.7 mg per pellet. Even after adjustment for water loss, this figure is much higher than the avenge of 0.82 mg per pellet recorded in our study with pollen of G. hirsirttrnt.…”

1991. Pollen morphology and its effect on pollen collection by honey bees, Apis rizellifera L. (Hymenoptera: Apidae), with special reference to upland cotton, Gossjpiruii hirsirfztm L. (Malvaceae). -Gram 33: [128][129][130][131][132][133][134][135][136][137][138]. ISSN 0017-3133. Honey bees, Apis riiellifera, forage readily on flowers of upland cotton, Gossjpirrni /zirsrrtrrrti, to harvest nectar. The abundant pollen gets caught in the haircoat of the bees, but cotton pollen is nevertheless rarely collected. Honey bee pollen collection effectiveness was therefore investigated in a flight room using cotton and five other spheroidal pollen taxa presented in sequence. Honey bees visited all pollen dishes, but ohra pollen (Abcbrroschrrs escirlerzrrrs) was never packed successfully by the bees landing in the pollen dish. Cotton pollen was collected by 16% of the landing foragers, pumpkin pollen (Crtcrrrbifa p e p ) by 7 1%. and pollen of corn (Zen rrrajs), pigweed (Aiiroraritlirrs palnzeri), and sunflower (Heliarithrrs arrrirm) were readily collected by nearly all foragers. The amount of time spent in the pollen dish was always short ( I to 9 seconds) and homogeneous among all pollen taxa, indicating that none of them was strongly repellent to the bees. The reduced effectiveness with which honey bees collected cotton pollen was demonstrated by the longer amount of time needed for pollen grooming and packing between two consecutive landings in the pollen dish and the small size of cotton pollen pellets (averages of 0.42 mg and 8.23 mg per pellet for cotton and corn pollen, respectively). This reduced efficiency in cotton pollen collection was associated primarily with the length of the spines on cotton pollen which physically interfered with the pollen aggregating process used by honey bees. In pollination studies for hybrid cotton seed production, honey bee foragers are often found in greater densities in the male-sterile flowers than in the male-fertile flowers (review in Vaissikre 1991). Several authors (Moffett et al. 1975, Loper 1984, Waller et al. 1985 have attributed this situation to a relative 'repellency' of cotton pollen and the sesquiterpenoid gossypol has been suggested as responsible for this effect (Moffett 1983), but Loper (1986) did not detect any gossypol in cotton pollen. Vansell (1944) suggested that the large size of cotton pollen grains and their covering with 'beads of viscid material' was such that honey bees were unable to pack these grains into their corbiculae. Buchmann MATERIAL AND METHODSTests were conducted primarily with six spheroidal pollen differing in grain morphology and surface topography ( Fig. 1 ; Table I). Zen iiioys, Heliorzthiis oriiiiiirs, and Aiiioror~rhiis polrircri pollen are readily collected by honey bees in the open, while that of Ciiciirbira pep0 is not often collected and we have never observed nor found a record of honey bees collecting Abebtioschirs pollen though they visit the flowers readily for nectar (Percival 1937(Percival . 1955Rashad & Parker 1958, Hurd 196...

“…It was also the dominant visitor on hybrid seed production plots of B.napus (Anon, 1999). Relatively higher abundance of A. mellifera was also reported in case of Gossypium arboretum (Tanda and Goyal, 1979) and on hybrid seed production plots of sunflower (Shinha and Atwal, 1996).In contrast to the present finding, Jhajj et al, (1996) observed that in case of raya crop various bee species in descending order of abundance were: A.dorsata >A. mellifera > A. florea. Panchbhavi and Rao (1978) and Panda, (1987) found that A. florea was dominant visitor on niger crop.Data regarding relative abundance on TFR-91 (Table 1,2 & 3) and TCMS-PR-05 (Table 4,5 & 6) lines of B.napus clearly showed that flowers of R line were much more attractive to honeybees than those of CMS line.…”

“…Sidhu and Singh (1961, 1962) showed that A. florea is an important pollinator of cotton. It has been reported that cotton is not a good pollen source for A. mellifera ( Moffett , 1976; Tanda and Goyal , 1979).…”

Studies on the possible competition for pollen between the honey bee, Apis mellifera sudanensis, and the imported dwarf honey bee Apis florea (Hym., Apidae) in North‐Khartoum (Sudan)

Based on identification of collected pollen, in the area of North Khartoum, 21 plant genera (ca. 21 spp.) proved to be the main pollen sources for the honey bee Apis mellifera sudanensis. The imported dwarf honey bee Apis florea exploited 11 of these. The main pollen flow in the study area occurred between early December and late March. This is reflected by the amount of pollen collected by colonies of A. mellifera sudanensis. In spite of observations conducted soon after the introduction of A. florea, which gave hints of competition between the two bee species, further studies showed that A. mellifera sudanensis and A. florea do seem to coexist. This coexistence is based on different daily rhythms of pollen collection. A. mellifera collected pollen of Acacia seyal, date palm, and onions early in the morning (and partly in the late afternoon), while A. florea started pollen collection mostly later in the morning and ended it earlier in the afternoon. But in contrast to A. mellifera, A. florea was collecting pollen all day without interruption, even at very high air temperatures. Niche overlap (concerning the times of visits to flowers) between the two bee species was very low in date palms, and of medium importance in Acacia seyal. But it is remarkable that in total, A. florea is always present in higher numbers than A. mellifera sudanensis, on flowers. The significance of the introduction of A. florea to Sudan for pollination is discussed.
