Sap sucking insects like thrips, aphids, mealybugs, whiteflies exploit the sugar rich phloem for growth and development. The excess sugar in the phloem sap creates osmotic imbalance leading to loss of water from haemolymph to gut lumen. In order to maintain osmolarity, sap sucking insects have developed structural adaptation (filter chamber) and also excrete excess sugar as honeydew through various orifices. The excreted honeydew is known to play very vital ecological role such as natural enemy calling (attracting parasitoids). In this regard scanty information is available on this important aspect for different sap sucking insects. In this study we are reporting for the first time on the composition of honeydew from the major horticultural thrips, Thrips palmi reared on French bean (Phaseolus vulgaris). LC-MS-MS analysis revealed the presence of 15 different sugars majorly inositol, fructose, maltose, glucose and sorbitol @ (130.9 ±0.47μg); (95.1±0.45μg); (60.7 ±0.28μg); (54.2 ±0.40μg) and (28.1 ±0.35μg), respectively.

Brassinolide (BL) represents brassinosteroids (BRs)—a group of phytohormones that are essential for plant growth and development. Brassinazole (Brz) is as a synthetic inhibitor of BRs’ biosynthesis. In the present study, the responses of Wolffia arrhiza to the treatment with BL, Brz, and the combination of BL with Brz were analyzed. The analysis of BRs and Brz was performed using LC-MS/MS. The photosynthetic pigments (chlorophylls, carotenes, and xanthophylls) levels were determined using HPLC, but protein and monosaccharides level using spectrophotometric methods. The obtained results indicated that BL and Brz influence W. arrhiza cultures in a concentration-dependent manner. The most stimulatory effects on the growth, level of BRs (BL, 24-epibrassinolide, 28-homobrassinolide, 28-norbrassinolide, catasterone, castasterone, 24-epicastasterone, typhasterol, and 6-deoxytyphasterol), and the content of pigments, protein, and monosaccharides, were observed in plants treated with 0.1 µM BL. Whereas the application of 1 µM and 10 µM Brz caused a significant decrease in duckweed weight and level of targeted compounds. Application of BL caused the mitigation of the Brz inhibitory effect and enhanced the BR level in duckweed treated with Brz. The level of BRs was reported for the first time in duckweed treated with BL and/or Brz.

Sharing Behavior

The main goal of this chapter is to assess knowledge sharing (KS) behavior among Library and Information Science (LIS) professionals and to assess how KS behavior contributes to professional growth and development in Bangladesh. Defining factors may encourage knowledge sharing behavior and can establish an important area of further LIS research. A modified survey questionnaire is developed and used to collect data on professionals' demographic and academic information, perception, attitude, intention, and intrinsic motivation to share knowledge. The authors found a significant relationship between the attitude of professionals toward KS and their intention to share knowledge. It is believed that the findings will help knowledge managers charged with the design of flexible KS system. This is the first time an effort will be made to assess professionals' perception on KS behavior in Bangladesh. The authors feel that this study may encourage the establishment of KS behavior in Bangladesh and beyond.

Khapra Beetle

Rearing experiments with Trogoderma granarium Everts were conducted to determine why the larvae fail to develop in certain pulses. The larvae were unable to penetrate whole grains of any of the nine pulses tested. In flour form, the pulses fell into three main groups. On flours of green, black, Bengal and kabuli grams, and cowpea and pigeon pea, development was as successful and rapid, or nearly so, as on wheat flour and showed little improvement from the addition of yeast. Development on flours of soybean and lentil was markedly slower, and showed marked improvement when yeast was added. By adding increased proportions of balanced diet, it was shown that the performance of larvae on soybean, lentil and even on French bean flours could be improved, but with the last two was not as good as with cellulose. It is concluded that lentils and French beans lack essential nutrients and may also contain a growth inhibitor.

This paper reports on the modification of two synthetic steps in the usual protocol used for obtaining EMICORON. EMICORON is a benzo[ghi]perylen-diimide, which was synthesized for the first time in our laboratory in 2012, and has shown to have in vivo antitumor activities that interferes with the tumor growth and development using a multi-target mechanism of action. The provided modifications, which involved the reaction times, the reaction conditions, and the work-up procedures, allowed the global yield of the process to be increased from 28% to about 40%. Thus, this new procedure may be more suitable for recovering higher amounts of EMICORON to be used in further preclinical studies.

Following Jane Plastow's contextual history of Eritrean theatre in NTQ50, Paul Warwick gave an account in the following issue of its previously undocumented role during the thirty-year Eritrean struggle for independence, describing the efforts of the freedom fighters to create theatre for the first time in a rural context. The Eritrean People's Liberation Front not only deployed theatre as a propaganda weapon, but also recognized its value as an agent for educating the people in matters ranging from women's rights to the benefits of modern medicine and farming methods: and with victory came measures further to stimulate the growth and development of theatre as part of Eritrean culture. Jane Plastow, in this third and concluding article, takes up the story with the invitation issued by the new government to her and her colleagues to initiate the ‘Eritrea Community-Based Theatre Project’, in an attempt both to widen the perspectives of Eritrean actors and to draw upon all relevant traditions, African and European, in developing a popular but distinctive theatre for the people. In addition to her role as director of the project, Jane Plastow is a lecturer at Leeds University, having worked in theatre for some years in a number of other African nations.
