The Heart of Civilization

Bruce Burgett 한국외국어대학교 영미연구소 2004 영미연구 Vol.10 No.-

This article surveys, argues for, and advances the recent postnationalist turn in American Studies scholarship by focusing on the emergence and persistence of the Anglo-American discourse of sentimental imperialism. Drawing specifically on the writings of Lord Shaftesbury (Sensus Communis) and Lydia Maria Child (Hobomok), the article suggests that the long history of Anglo-American sentimentalism needs to be understood in relation both to the rise of liberal strategies of governmentality in the late seventeenth century and to the increased focus on the body and its sensations as a ground for political debate in the early eighteenth century. Sentimental imperialism, in this context, roots the abstract universalism of Anglo-American liberalism in the particularities of local practices of embodiment. In turn, these specific articulations of liberalism"s (globalizing) claims and its (localizing) procedures underwrite the theory and practice of Anglo-American imperialism. The article also suggests that scholars and critics of post-nationalist American Studies should be interested not simply in how this form of sentimental imperialism operates, but also in mapping some of its less predictable effects and genealogies.

Drone flight of a queen-right Apis mellifera L. colony was compared between two geographic locations. The major drone flight was observed in 1348-1448h from Corvallis, OR, USA and 1402-1452h from Andong, Korea. There was no bcdy size difference between egressing and returning drones, but significant difference was found in the body weight; 24.1㎎ lighter for returning drone. Drones stayed more in the middle part of the bottom hive super. Further discussion was made on drone biology and sexual selection.

Honey moisture content from beneath capped honey storage cells was examined for four species of honey bees in northern Thailand. Three species, Apis dorsata, A. florea, and A. cerana are indigenous to SE Asia, the fourth species, A. mellifera, is a recently introduced species. It is assumed that capped honey will possess the lowest moisture content attainable under tropical conditions. Average honey moisture content was as follows: A. dorsata 22.7%, A. florea 20.1%, A. cerana 21.2% and A. mellifera 18.8%. Capped honey storage cells for the indigenous honey bee species frequently exceed the moisture content standard set by regulatory agencies for A. mellifera honey in Europe. The introduced, temperately adapted A. mellifera is capable of lowering honey moisture to regulatory standards even in the environmental restraints of high ambient temperature and relative humidity of northern Thailand.

Yellowjackets are the second nuisance after vespid hornets as predator of honey bee in the family Vespidae. Understanding the nest structure and dynamics would provide the platform for the management planning of this social group. From the apiary in Corvallis, Oregon, USA, three species of yellowjackets; Vespula pensylvanica, V. vulgaris and Dolichovespula maculata were identified. And two representative nests were excavated, one of ground nest and the other of aerial nest. A ground nest of V. vulagris was enveloped with fragile pulps of scallop shape, consisted of four layers of combs connected by cordlike suspensoria. The dimension of hexagonal cell is 1㎝ high with 0.6cm diagonal length. In September, there were already developing reproductives in larger cells of 1.5cm high and 0.8㎝ diagonal length. An aerial nest of D. maculata was enveloped with more resistant pulps of wavelike shape. The circular entrance was enforced with six layers of pulps, but remaining surface was enveloped with three layers of pulps. On 20 July, there was two layers of combs which were connected by buttresslike suspensoria. No reproductive was found at this time. Cell dimension was 1.5㎝ high with 0.8㎝ diagonal length. Capped brood cell was ovally inflated with white colored material. Social structure, lifehistory and management concerns of yellowjackets were further discussed.

Biometric Studies of the Stingless Bee Tetragonula laeviceps Complex (Apidae: Meliponini) from Northern Thailand

Bajaree Chuttong,Michael Burgett 한국양봉학회 2017 韓國養蜂學會誌 Vol.32 No.4

Biometrical information for five colonies of the Tetragonula laeviceps complex from Chiang Mai province, Thailand, was collected. The examination was conducted from September to November 2016. The range of colony age was one to five years. Results reveal an average number of queens (2.0±0.7), workers (5,823.6±2,703.3), drones (349.8±701.0), brood cells (9,911.0±4,795.3), honey pots (433.0±312.4) and pollen pots (711.8±305.9). The average size of a honey pot was 6.1 ±1.0mm in width and 7.3±1.1mm in height. The average size of a pollen pot was 6.4±0.3mm in width and 7.7±0.4mm in height. The results show intraspecific variation within the species that is the most common stingless bee species used in Thai meliponiculture. These observations support the contention that T. laeviceps complex comprises a cryptic species.

합성 꿀벌유충페로몬 처리가 서양종꿀벌(Apis mellifera L.) 먹이활동에 미치는 영향

정철의(Chuleui Jung),Michael Burgett 한국양봉학회 2011 韓國養蜂學會誌 Vol.26 No.4

Honeybee brood pheromone is the chemical substance which induce the physiological, developmental manipulation of the honeybee produced by the larvae of honeybee. A blend of ten fatty acid esters found on the cuticle of young honeybee larvae are now synthetically produced by commercial company. We tested the commercial materials on honeybee foraging behavior. Bee receiving brood pheromone collected more pollen than bees without brood pheromone treatments. Also honeybee coloney with brood pheromone treatment survived better than the hives without brood pheromone in the food scarce environment. The same patterns were found in the honey storage. Thus we propose that honeybee brood pheromone could be utilized for better production of honeybee colony as well as honeybee service such as pollination of the crops.

Honeybees are important pollinators in agricultural and natural ecosystems. Conservation of wild pollinators as well as managed honeybees are critical for sustainable ecosystem service. Honeybees are exposed to various threats including pesticides. We tested the susceptibility of the neonicotinoids; Thiamethoxam, Imidacloprid, and Clothianidin, and a carbamate pesticide; carbaryl to four species of honey bees, Apis florea, A. cerana, A. mellifera, and A. dorsata from northern Thailand. Formulated pesticide products were serially diluted and utilized for oral toxicity test. When treated with the recommended concentrations, all tested adult bees were dead within 18 hr for all tested chemicals. Feral honeybee species showed higher LC50 values for 3 neonicotinoids than the managed honeybees. When treated with carbaryl, LC50 values were not different between the honey bee species. The results indicate that tested insecticides would pose risks not only to managed honeybees but also the indigenous honey bee species. Additionally Korean populations of A. mellifera showed higher LC50 values for 4 pesticides compared to the Thailand A. mellifera population, indicating that there might be complex interactions of differential exposures of those chemicals in agricultural fields and honeybees.

Foraging behavior and pollination efficiency of honey bees (Apis mellifera L.) and stingless bees (Tetragonula laeviceps species complex) on mango (Mangifera indica L., cv. Nam Dokmai) in Northern Thailand

Chuttong Bajaree,Panyaraksa Lakkhika,Tiyayon Chantaluk,Kumpoun Wilawan,Chantrasri Parinya,Lertlakkanawat Phurichaya,정철의,Burgett Michael 한국생태학회 2022 Journal of Ecology and Environment Vol.46 No.3

Background: The mango is one of the essential fruit trees for the economy of Thailand. Mango pollination relies primarily on insects. Other external forces, such as wind, are less efficient since pollen is sticky and aggregating. There is only one report from Thailand on the use of bees as mango pollinators. The study of the behavior and pollination efficiency of honey bees (Apis mellifera) and stingless bees (Tetragonula laeviceps species complex) was conducted in Nam Dokmai mango plantings in Phrao and Mae Taeng districts, Chiang Mai province, between February and March 2019. Results: Our results reveal that the honey bees commenced foraging earlier than the stingless bee. The number of flowers visited within 1 minute by honey bees was higher than that visited by stingless bees. The average numbers of honey bees and stingless bees that flew out of the hive per minute from 7 a.m. and 6 p.m. in the Phrao district were 4.21 ± 1.62 and 9.88 ± 7.63 bees/min, respectively, i.e., higher than those observed in Mae Taeng, which were 3.46 ± 1.13 and 1.23 ± 1.20 bees/min, respectively. The numbers of fruits per tree were significantly higher in the honey bee and stingless bee treatments (T1 and T2) than in the open pollination treatment (T3). The number of fruits between T1 and T2 treatments was not different. In the pollinator exclusion treatment (T4), no fruit was produced. Fruit size factors were not significantly different among T1, T2, and T3 treatments. Conclusions: Our results showed that insect pollination is crucial for mango production, especially with the Nam Dokmai variety in Northern Thailand. As pollinator exclusion treatment showed no fruit set, and pollinator treatment significantly increased the fruit sets compared to open access plots, a managed pollinator program would benefit the mango growers for better productivity. Both the honey bee and the stingless bee were shown to be effective as pollinators.
