Abstract: The objectives of the study were to analyze the nutritional composition of some species of pine caterpillars and to encourage utilization of these forest insect pests, therefore, the study constituted part of IPM (Integrated Pest Management) for these forest pests in China. The results showed that the crude protein (CP) content of the pupae of 4 species ranged from 53.55% to 61.26%. The CP content of the adults of 2 species was 58.04% and 68.30% respectively. The fat and the energy content ranged from 19.75 to 26.46% and from 406 to 473 kcal per 100g for the pupae; 6.56 to 24.63% and 327 to 454 kcal per 100g for the adults respectively. As compared with the essential amino acids according to WHO/FAO/UNU pattern, some of the essential amino acids for human adult nutrition are found to be higher than the levels as recommended by WHO/FAO/UNU.

Abstract: Tree species diversity and their potential uses were assessed in Kizee Village Forest Reserve, Muheza District. Household survey, focus group discussions, key informant interview and tree diversity surveys were used during data collection. Data were analyzed both qualitatively and quantitatively using the Statistical Package for Social Science. Tree species diversity was computed using Shannon-Wiener diversity index. A total of 32 tree species from 20 families with different uses were identified. The most dominant tree species identified was Albizzia antihelmintica which contributed 19.83% of all tree species. The forest is a potential source for timber, charcoal, firewood, fodder, medicinal plants/trees and poles. Small diameter class trees (≤ 15cm) contributed 63.1% of all standing trees. The forest had stem density of 434 stems Ha-1 and Shannon-Winner Diversity Index of 2.2717 which were biologically within the normal tree diversity status. Majority (70%) of the respondents were aware of types of tree species available in the forest. The index obtained showed a relative achievement of forest policy of improved forest quality and stable forest community. However, more attention is needed to make sure that the forest is not degraded.

Abstract: This study aimed to analyze the dimensions of fiber and its derivatives in order to utilize as an alternative material of pulp and paper making. Dimensions of fiber include fiber length, fiber diameter, lumen diameter, and cell wall thickness; the values of derivatives studied were runkell ratio, felting power, muhlstep ratio, flexibility ratio, and coefficient of rigidity. Sugar palm frond came from Pingaran Village, Astambul District, Banjar Regency, South Kalimantan. The results show the length of fiber is included in fiber quality class III, Runkell ratio Value, Muhlstep ratio value, and the flexibility ratio value of fiber quality class I, felting power value of fiber quality class IV, Coefficient of Rigidity value of fiber quality class II. Overall fibers produced are included in fiber quality class II with a score of 450. Based on the value of fiber dimension and fiber dimension derivative, the fiber of sugar palm can be used as an alternative raw material for pulp and paper making.
