“…Second, GF may act to attract migratory pollinators such as honey bees to the area, thereby enhancing pollination success and outcrossing (Sakai, 2002). Regardless of which hypothesis is more likely to be correct, the spatial separation of conspecifics and the intense competition amongst individual plants for the attention of pollinations during a GF strongly suggest that many Dipterocarp tree species of the South-east Asian lowland forests are adapted for pollination by migratory honey bees which can rapidly increase in population size by both reproductive and migratory swarming (Itioka et al, 2001). No other pollinators have both these capacities.…”

“…A. dorsata colonies are highly philopatric, often migrating over large distances, but returning to the same nesting site every year (Butani, 1950;Koeniger and Koeniger, 1980;Underwood, 1990;Dyer and Seeley, 1994;Kahona et al, 1999;Neumann et al, 2000;Paar et al, 2000;Sheikh and Chetry, 2000;Thapa et al, 2000;Itioka et al, 2001;Paar et al, 2004). Moreover, A. dorsata tend to nest in large aggregations, sometimes with more than 100 colonies on a single tree Paar et al, 2004).…”

-East Asia is home to at least 9 indigenous species of honey bee. These bees are extremely valuable because they are key pollinators of about 1/3 of crop species, provide significant income to some of the world's poorest people, and are prey items for some endemic vertebrates. Furthermore, Southeast Asian Dipterocarp forests appear to be adapted to pollination by honey bees. Thus long-term decline in honey bee populations may lead to significant changes in the pollinator ecology of these forests, exacerbating the more direct effects of deforestation and wood harvesting on forest health. Although complete extinction of any honey bee species is seen as unlikely, local extinction is likely to occur across extensive areas. The most significant threats to local honey bee populations are deforestation and excessive hunting pressure. Conservation of East Asian honey bees requires immediate action to determine what rate of colony harvesting by honey hunters is sustainable. This requires information on the demography of hunted populations, particularly the intrinsic growth rates and the rates of harvest.Apis / Conservation / Honey hunting / demography / sustainable harvest / pollination / dipterocarp forests

“…A single Tualang tree may contain about 100 Apis dorsata nests, and each nest, with the profile of a half-moon and up to 1.5 meters across, may contain about 30,000 bees. Collectively, these bees can produce up to 450 kg of honey from one tree (Oldroyd, Osborne & Mardan, 2000;Itioka , Inoue, Kaliang, Kato & Nagamitsu, 2001).…”

Results of recent trial have shown some negative effects of HRT on postmenopausal women. Therefore, there has been a need to search for an alternative treatment and honey is one of the well known traditional remedies used in minimizing postmenopausal problems. The objectives of the study were to investigate the effects of Tualang honey on the cardiovascular risk factors, changes in hormonal profiles and also effect on the bone. A randomized controlled trial comparing the effects of Tualang honey 20 g/day and HRT for a 4-month intervention period among healthy postmenopausal Malay women aged 45-60 years old was conducted. The primary outcome measures were changes from baseline on the cardiovascular risk profiles, hormonal profiles and effect on bone. Tualang honey compared with low dose HRT, consumed for 4 months by postmenopausal women had no demonstrable effects on the parameters examined such as blood pressure measurement, body mass index and waist circumference. There was no significant difference in the lipid profile, blood sugar profile and bone density between the two groups at the end of the study period.

“…Chrysomelid beetles seem to change their food types from leaves to flowers in response to general flowering (Sakai et al, 1999a). Giant honeybees immigrate to lowland mixed dipterocarp forests as soon as general flowering starts, and when it finishes they leave (Itioka et al, 2001). However, stingless bees show none of these responses, i.e., they do not show rapid population growth (Inoue et al, 1993), change food types from nectar and pollen to others, or migrate over a long distance (Inoue et al, 1984).…”

-General flowering is a type of supra-annual mast flowering at community level in Southeast Asia, which occurred in 1996 after a four-year interval in northern Sarawak, Malaysia. To examine foraging responses to general flowering, foraging activity and pollen diets of subterranean stingless bee (Trigona spp.) colonies were compared over 3 periods in 1994 and 1996. Among variables of foraging activity (frequency of forager returns, proportions of nectar and pollen foragers), only the frequency of forager returns was significantly higher in 1996 than in 1994. The proportion of nectar foragers differed significantly among periods within a year. Among variables of pollen diet breadth (pollen type richness, diversity and evenness indices), none differed significantly between years or among periods. Pollen diet similarity between colonies did not differ significantly between years, although it differed among periods. lowland mixed dipterocarp forests / foraging / general flowering / nectar / pollen diet / Sarawak / Trigona
