The stingless bee Melipona fuliginosa Lepeletier is described as being aggressive robber, but there is little information about its raids. Here, we describe two different raids of M. fuliginosa on other Melipona species: Melipona paraensis Ducke and Melipona fasciculata Smith. The robbing behavior was observed in the Volta Grande do Xingu region (Pará) and Carajás National Forest (Pará), and the attacks by M. fuliginosa occurred at the end of the dry season, shortly before the start of the rainy season, a time of flower scarcity. The raid on M. paraensis hive lasted five days and involved no deaths of worker bees of both species; the robbers collected honey and wax. During the pillaging, M. fuliginosa workers dedicated themselves exclusively to this task; their flight activity peaked between 8:00 a.m. and 12:00 p.m. but lasted until 6:00 p.m, which is atypical for the species. The raid on M. fasciculata differed from the other event because it led to the extermination of all forager workers of fi ve colonies, however, the brood combs as well as the callow workers were preserved; the robbers collected honey and wax. M. fuliginosa attack defensive and non-defensive colonies, the events can cause severe damage and may lead to death of the victim colony in natural conditions. Flight activity varies from foraging on fl owers during dawn to all day long robbing, showing considerable plasticity to obtain food resources. Robbing behavior could be associated to fl ower scarcity and artificial feeding.

Bees are prolific pollinators and are responsible for the pollination of most wild and cultivated plants. This study aimed to learn about the flight activity of the stingless bee Plebeia aff. flavocincta in tropical conditions as a parameter to evaluate the general state of the colonies, and to investigate the role of food resources and environmental factors in their flight activities. We recorded the worker flight activity (exit, when they leave the hive; trash, when they discard litter; entry with pollen; and entry without pollen) of four colonies throughout the year and monitored biotic and abiotic conditions that could affect the bee´s external activities, such as blooming and meteorological conditions.  Results showed that the colonies remained active throughout the year and presented  two major periods of external activity; one corresponding to the greater food supply in the field, and the other to time of the year when there were few food resources available. Also, the four flight activities were all strongly correlated with each other. We concluded that in tropical conditions, external activities of P. aff. flavocincta are regulated mainly due to the food resources available rather than the prevailing weather conditions and they are an important indicator of the general health of the colony.

The present study aimed at evaluating differences in rotifer distribution in three estuarine zones in an inverse estuary located in the Semiarid Region of Brazil. Zones were chosen based on their proximity to the ocean and river border as a means of reflecting a horizontal salinity gradient. High freshwater discharge during the rainy season was the major determinant of rotifer composition. On the other hand, due to higher salinity values during the dry season, very low values of species richness and abundance were observed in all zones. Therefore, the study highlights the constraints of salinity and the positive influence of seasonality and river proximity on rotifer species in a semiarid estuarine environment.

A study on the life cycle of the silkmothAnaphe panda(Boisduval) was conducted in two different habitats of the Kakamega Forest in western Kenya: Ikuywa, an indigenous forest, and Isecheno, a mixed indigenous forest. Eggs were laid in clusters, and the incubation period ranged from 40 to 45 days. Larvae fed onBridelia micrantha(Hochst) and passed through seven instars. The developmental period took between 83 to 86 days in the dry season and 112 to118 days in the rainy season. The pupal period ranged between 158 and 178 days in the rainy season and, on the other hand, between 107 and 138 days in the dry season. But the later caught up in development with those that formed earlier. Moths emerged from mid-October until mid-May. Longevity of adultAnaphe pandamoths took between 4 and 6 days, but generally females seemed to live longer than males. The moth also seems to have higher lifespan in the indigenous forest compared to the mixed indigenous forest.

The clinical and bacteriological findings in two cows the udders of which became infected under natural conditions with hemolytic streptococci of the scarlet fever type are discussed. One of the cows was found in a herd supplying raw milk to a small town where a milkborne outbreak of scarlet fever had occurred a short time before. When small numbers of the streptococcus obtained from this case were injected into the udder of a normal cow severe mastitis accompanied by a well marked general reaction resulted. Evidence leads to the conclusion that a severe attack of mastitis due to this organism in one quarter does not sufficiently immunize the other quarters to protect them completely since the streptococcus can be readily implanted in them. The secondary infections were much milder than the original process.

The objective of the present study was to test three different procedures for DNA extraction of Melipona quadrifasciata based on existing methods for DNA extraction of Apis, plants and fungi. These methods differ in the concentrations of specific substances in the extraction buffer. The results demonstrate that the method used for Apis is not adequate for DNA extraction from M. quadrifasciata. On the other hand, with minor modifications this method and the methods for plants and fungi were adequate for DNA extraction of this stingless bee, both for adults and larvae

South Barito is an area of rattan and rattan production center of the province of Central Kalimantan, on the other hand is one area that has natural conditions very conducive to the development of rattan. This study reveals how patterns in addition to planting and processing of rattan traditionally also analyze the socio-economic level of society. Research conducted in South Barito regency, District Karau in Two Villages is Bangkuang and New Salat. The village of the second sample is determined gardens and population are farmers who cultivate cane with sampling methods by simple random sampling, because the peasant population is homogeneous, the number of samples in each village 34 respondents or 68 farmers overall. The result showed that in general the rattan garden where the studies were not well-maintained, where the average of respondents (45%) said that maintenance is only performed at the time of going to the harvesting or one for rattan planting. Besides the low price of rattan is led to a reduction of land management / rattan gardens intensively. and production of rattan average yield of 2.6 tons ha-1 or 245.5 clumps of cane ha-1. For the villagers of business administration studies despite conditions that are considered less favorable, but they still look forward to the Government's policy to remain aligned to the Farmers Rattan. In addition, because cane is inherited and used as a hallmark of South Barito society in general.Barito Selatan merupakan daerah penghasil rotan dan sentra produksi rotan provinsi Kalimantan Tengah, selain itu merupakan salah satu wilayah yang memiliki kondisi alam yang sangat mendukung bagi perkembangan rotan. Penelitian ini selain untuk mengungkapkan bagaimana pola tanam dan pengolahan rotan secara tradisional juga  menganalisis tingkat sosial ekonomi masyarakat. Penelitian dilaksanakan di Kabupaten Barito Selatan, Kecamatan Karau di Dua Desa yaitu Bangkuang dan Salat Baru. Dari kedua Desa tersebut ditentukan kebun sampel dan populasi masyarakat  yaitu  petani yang mengusahakan rotan dengan metode pengambilan sampel secara simple random sampling, karena populasi petani bersifat homogen, jumlah sampel di masing-masing desa 34 responden atau keseluruhan 68 petani. Dari hasil penelitian diperoleh bahwa pada umumnya kebun rotan di tempat penelitian tersebut tidak terpelihara dengan baik, dimana rata-rata responden (45%) menyebutkan bahwa pemeliharaan hanya dilakukan pada saat akan dilakukan pemanenan atau satu kali selama rotan itu di tanam. Selain itu rendahnya  harga  rotan  sangat  berdampak pada berkurangnya pengelolaan lahan/kebun rotan secara intensif. dan hasil produksi rotan rata-rata diperoleh 2,6 ton ha-1 atau 245,5 rumpun rotan ha-1. Bagi masyarakat Desa studi walaupun kondisi tataniaga yang dianggap kurang menguntungkan, namun mereka masih berharap kebijakan Pemerintah tetap berpihak kepada Petani Rotan. Di samping itu  karena pada umumnya rotan merupakan warisan dan digunakan sebagai ciri khas masyarakat Barito Selatan.

Trigona Carbonaria

Temporal patterns of flight activity and influence of climatic variables on activity of colonies of the potentially useful crop pollinator, Trigona carbonaria Smith, were investigated. Colonies of T. carbonaria were active all the year at the experimental site but the daily activity period was longer in the warmer months. Intensity of daily flight activity was greatest in September and least in May. Temperature and radiation were the most important variables affecting flight activity. They impose thresholds on activity, with flight occurring only at temperatures greater than 18-degrees-C and radiation greater than 15 W m-2. Temperature and radiation also influence the intensity of activity above the thresholds. Relative humidity, vapour pressure, cloud cover and wind speed had no significant effect. A variable measuring the hours from daily peak of activity was significantly correlated with flight activity, indicating an intrinsic diel pattern of activity. Daily variation in flight activity, representing the influence of unmeasured variables, was also significant.

The flight activity and flight muscle of the melon fly, Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae) were observed. The Tethered technique was used to observe the flight activity in this study. The flight activity, and wing and flight muscles were compared between male and female melon flies. The results indicate that the female was relatively better and strong flier than the male. The mean duration of the flight activity of the females was 13.90 min/hour and of the males was 7.12 min./hour. The mean length, width, volume of wings of the males were 6.07 mm, 2.67 mm and 10.99 mm³, respectively. On the other hand, the mean length, width and volume of the wings of females were 7.07 mm, 2.87 mm and 15.60 mm³, respectively. In case of wing muscles, the mean volume of dorsal longitudinal muscle (DLM) in male and female was found 5.20 mm³ and 5.67 mm³, respectively. The mean length of flight wing muscle of male and female was 2.22 and 2.23 mm, respectively and the mean breadth of male and female was 1.65 and 1.77 mm, respectively. Dhaka Univ. J. Biol.
