BISWAS Oilseed Research Centre, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur-1701, Bangladesh Abstract Thirty nine species of insect pests were found to infest soybean crop at their different growth stages in Noakhali region of Bangladesh during January to May, 2010 and 2011. Among the recorded pest species, six species namely, hairy caterpillar, Spilarctia obliqua (Walker); leaf roller, Lamprosema indicata F; common cutworm, Spodoptera litura F; pod borer, Helicoverpa armigera (Hubner); stem fly, Ophiomyia phaseoli (Tryon) and white fly; Bemisia tabaci Genn. were considered as the major pests while the rests were of minor importance on the basis of population densities per plant, nature and extent of damages, and yield reductions. Most of the major and minor pests appeared in the crop during vegetative to flowering stages (30-50 Days after sowing) and the maximum insect population and their infestation occurred during flowering and pod formation stages of the crop throughout the study period. Key words: Insect pests, Soybean, Glycine max, Damage, Succession, Crop stages Introduction Soybean (Glycine max L.) is one of the most important crops which is grown for oil and protein in both the rabi and kharif seasons. Seeds of soybean contain about 42% protein and 20% oil and provide 60% of the world supply of vegetable protein and 30% of the edible oil (Fehr 1989). In Bangladesh this crop is comparatively new but soybean oil is very much popular as edible oil. However, recently the crop gained popularity in the poultry industry and its cultivation expands day by day. In the Greater Noakhali region ( Noakhali and Laxmipur districts) soybean is the major oilseed crop and is extensively cultivated. Cultivation of soybean covered about 55,000 hectares of land and produced about 90,000 metric tones of seeds during the period 2009-2010 in Bangladesh (Anonymous 2011). One of the major constraints to the successful soybean production in Bangladesh is the damage caused due to insect pests. Research experiences reveal that 15 - 20 percent of the total soybean production is lost directly or indirectly by the attack of insect pests every year (Biswas 2008). In order to evolve economically feasible, ecologically sound and socially acceptable pest management strategies, detailed information on the pest complex, their status and sequence of appearance during the crop period, losses and type of damage are of great importance (Jayanthi et al. 1993). In Bangladesh, check lists of insect pests of soybean and their succession in relation to crop stages are scanty. Only the list of some insect 2 Biswas pests of soybean in Bangladesh was recorded (Sardar and Debnath 1984, Kaul and Das 1986, Ali 1988, Begum 1995, Biswas et al. 2001 and Biswas 2008). Therefore, the present research work was undertaken to record the insect pests of soybean, their nature of damage, incidence, infestation and time of appearance with the crop stages. Materials and Methods The research work was conducted in the field of Subarna Char, at Noakhali and in the laboratory of Oilseed Research Centre, BARI, Gazipur during rabi 2009-2010 and 2010- 2011 crop seasons. The survey was conducted from one hectare land soybean field cultivated by the farmers with the supervision of scientists of Oilseed Research Centre, BARI, Joydebpur, Gazipur. The experimental plot measured 10 m X 10 m. The seeds of soybean were sown in the plots on 4th week of December of 2009 and 2010. There were four replications and plots were selected following a Randomize Complete Block Design. The rows and plants were spaced 30 cm and 10 cm apart, respectively. The recommended agronomic practices for raising the crop were maintained following the work of Mondal and Wahhab (2001). Observation on species of insect pests with their population per plant was recorded from seedling to matured stage of the crop from 10 randomly selected samples of the plants in each plot. The time of appearance of the pests were observed and recorded. The nature of damage and feeding behaviour of the insects were carefully observed and their photographs were taken in the crop fields and in the laboratory. The recordings of data were included visual observations, hand tens, and hand picking of insects from the standing crops during 7:00-10:00 a.m and 4:00-6:00 p.m at weekly intervals. Some insects were also collected by aspirators for laboratory studies. The collected insects were preserved in the insect box and vial having 75% alcohol for identification. Relative population of insect was counted as suggested by Biswas et al. (2001). The collected insects were also reared in the laboratory at an ambient temperature (24-340 C) in cages and preserved in the insect boxes. The insects (specimens) were preliminarily identified following Maxwell- Lefroy (1909), Borror et al. (1975), Fletcher (1985), Nair (1986), Singh (1990) and Biswas (2008). The insects were graded as major and minor on the basis of their population density per plant, nature and extent of damage of the crop and the yield reduction. The insect pests were also grouped as stem feeders, leaf feeders, leaf roller, sap sucker and borer on the basis of their feeding behaviour. Results and Discussion Pest complex of soybean: Thirty nine species of insect pests belonging to seven orders and 22 families were found to infest at the different growth stages of soybean crop in Noakhali region, Bangladesh during rabi seasons of two consecutive years 2009-10 and 2010-11(Table 1). Of these, only six species namely, hairy caterpillar, Spilarctia obliqua (Walker); leaf roller, Lamprosema indicata F.; common cutworm, Spodoptera litura F.; Insect pests of soybean (Glycine Max L.) 3 Table 1.

Sediment dispersal processes and management in coping with climate change in the Meghna Estuary, Bangladesh MAMINUL HAQUE SARKER, JAKIA AKTER, MD RUKNUL FERDOUS & FAHMIDA NOOR Center for Environmental and Geographic Information Services (CEGIS), House no.6, Road no. 23/C, Gulshan-1, Dhaka-1212, Bangladesh [email protected] Abstract Due to flat terrain and dense population, the Bengal Delta is highly vulnerable to sea level rise. At present the delta building process is active in the Meghna Estuary. Information on sediment dispersal processes in the estuary and their response to different exogenic and anthropogenic forces is an important requirement for managing the sediment and developing adaptive measures to counter the potential impact of climate change. Historical maps, satellite images and tidal water level data were analysed and the response of the Meghna Estuary to extreme events, e.g. the 1950 Assam earthquake, as well as anthropogenic interventions, was assessed. The issue of sediment management was addressed, based on an understanding of the response of the estuary to the extreme natural event and anthropogenic interventions, along with an assessment of the response of the estuary to sea level rise. Among other interventions, emphasis has been directed to promoting vertical accretion by injecting sediment into polders. Key words Bengal delta; Meghna Estuary; sea level rise; sediment dispersal processes; vertical accretion; sediment injection INTRODUCTION Deltas are a large accumulation of both fluvial and marine sediments which have infilled river mouths and extended onto the continental shelf (Fookes et al., 2007).

  • Cyclone Disaster Vulnerability and Response Experiences in Coastal
    Cyclone disaster vulnerability and response experiences in coastal Bangladesh Edris Alam Assistant Professor and Disaster and Development Centre Affiliate, Department of Geography and Environmental Studies, University of Chittagong, Bangladesh and Andrew E. Collins Reader in Disaster and Development, Disaster and Development Centre, School of Applied Sciences, Northumbria University, United Kingdom For generations, cyclones and tidal surges have frequently devastated lives and property in coastal and island Bangladesh. This study explores vulnerability to cyclone hazards using first-hand coping recollections from prior to, during and after these events. Qualitative field data suggest that, beyond extreme cyclone forces, localised vulnerability is defined in terms of response processes, infrastructure, socially uneven exposure, settlement development patterns, and livelihoods. Prior to cyclones, religious activities increase and people try to save food and valuable possessions. Those in dispersed settlements who fail to reach cyclone shelters take refuge in thatched-roof houses and big-branch trees. However, women and children are affected more despite the modification of traditional hierarchies during cyclone periods. Instinctive survival strategies and intra-community cooperation improve coping post cyclone. This study recommends that disaster reduction programmes encourage cyclone mitigation while being aware of localised realities, endogenous risk analyses, and coping and adaptation of affected communities (as active survivors rather than helpless victims). Keywords: coastal and island people of Bangladesh, coping, cyclone vulnerability, local response Introduction With the effects of natural hazards rising in terms of loss of life and injuries in poorer nations (ISDR, 2002; World Bank, 2005; CRED, 2007), institutional disaster reduction approaches (ISDR, 2004; UNDP, 2004; DFID, 2005) and approaches adaptable to individual social and livelihood experiences are required.

  • INSECT PESTS of GROUNDNUT (Arachis Hypogaea L.), NATURE of DAMAGE and SUCCESSION with the CROP STAGES
    ISSN 0258-7122 Bangladesh J. Agril. Res. 39(2): 273-282, June 2014 INSECT PESTS OF GROUNDNUT (Arachis hypogaea L.), NATURE OF DAMAGE AND SUCCESSION WITH THE CROP STAGES G. C. BISWAS1 Abstract Thirty six species of insect pests were found to infest the different growth stages of groundnut crop at Gazipur, Bangladesh during the rabi seasons of 2008-09 and 2009-010. Among the recorded pest species, the hairy caterpillar, Spilarctia obliqua ( Walker); common cutworm, Spodoptera litura F.; jassid, Empoasca terminalis Distant ; leaf miner, Stomopteryx nerteria M. and leaf roller, Anersia ephippias (Meyr.) were considered as the major pests, while the rests were of minor importance on the basis of their population densities/plant, nature and extent of damage and yield reductions. Most of the major and minor pests infested during the vegetative to pre-maturity stages (45-95 DAS) and the maximum infestation occurred during pod formation and pod filling stages (50- 80 DAS) of the crop in both the years. Keywords: Insect pests, groundnut, damage, succession, crop stages. Introduction Groundnut (Arachis hypogaea L.) is an important oilseed crop in Bangladesh on the basis of both in acreage and annual production (Biswas et al,. 2000; Mondal and Wahhab, 2001.) Its cultivation covered about 87,000 hectares and produced about 1,25,000 metric tons of seeds during 2011-12 (Krishi Diary, 2013). One of the major constraints to the successful groundnut production in Bangladesh is the damage caused by insect and mite pests. Studies reveal that 15 - 20 percent of the total oilseed production is lost directly or indirectly by the attack of insect and mite pests every year (Biswas and Das, 2011).

  • COASTAL DEVELOPMENT STRATEGY ( Approved at the 2Nd Meeting of the Inter-Ministerial Steering Committee on ICZMP Held on February 13, 2006 )
    Ministry of Water Resources Government of the People’s Republic of Bangladesh COASTAL DEVELOPMENT STRATEGY ( Approved at the 2nd meeting of the Inter-Ministerial Steering Committee on ICZMP held on February 13, 2006 ) Water Resources Planning Organization February 2006 PREFACE The coastal zone of Bangladesh is often perceived as a zone of multiple vulnerabilities. But it has much potentials and opportunities. Moreover, it contains several important and critical ecosystems. By harnessing and exploiting its opportunities in systematic and coordinated way, the coastal zone can make a substantial contribution to achieve the national goals of accelerated poverty reduction and economic growth. The need for an area specific program in coastal Bangladesh was recognized in a number of earlier initiatives and the policies and programs of different government agencies. Integrated Coastal Zone Management Plan (ICZMP) project was implemented by Water Resources Planning Organization. One of the key outputs of the project is the Coastal Zone Policy (CZPo) which was approved by the government on 17 January 2005. The policy provides the directives and the framework for the development and implementation of integrated coastal zone management plan. It also gives direction for management of the coastal development process. The Coastal Development Strategy (CDS) focuses on the implementation of the coastal zone policy. The CDS was approved at the second meeting of the Inter-Ministerial Steering Committee on ICZMP held on 13 February 2006. The distinctive development opportunities of the coastal zone are considered as instrumental in reducing vulnerability and poverty of coastal communities. This strategy is an attempt to unlock the potentials of the coastal zone along with strategies to mitigate natural and man- made hazards and to preserve, restore and enhance coastal ecosystems.

The new species is most similar to S. illustrella (Hübner, 1796) and S. orientalis Li & Zheng, 1998 from which it can be reliably distinguished by characters of the genitalia. Sophronia iciculata Omelko, 1999, syn. n., is a junior synonym of S. orientalis; and S. marginella Toll, 1936, syn. n., is a junior synonym of S. consanguinella Herrich-Schaffer, [1854]. Sophronia alaicella Caradja, 1920 is redescribed, and the adult and the male and female geni- talia are illustrated.
