A B S T R A C TThe red palm weevil (Rhynchophorus ferrugineus) is a bug local tropical areas of Southeast Asia are a vital nuisance of coconut (Cocos nucifera L.). Trade is the fundamental driver of its worldwide spread development in the Mediterranean locale and the close East. In its local reach Rhyncophorus ferrugineus postures financial issues in the loss of coconut harvest stays controlled commonly. However it extremely well adapted to the new environment development by tending to new species, for example, the date palm (Phoenix dactylifera L.) creating genuine monetary issues. Eventually, it changes the tourist's scenes in Spain and France, tending to the Canary palm (Phoenix canariensis Chabaud) and consequently that the European Union for a long times an Action Plan against red palm weevil, considering observing the development and import of palm, mindfulness and plagued palms demolition arrangement. On the other hand, looking ahead in hopes of a fight developer effective means pushed through a study on the behaviour and biology of the weevil either in the wild or in its amplified territory.

A study was conducted at Hatiya and Nijhum Island, Noakhali in the mid coastal region of Bangladesh to identify feasibility of mud crab culture for a study period of six months from January 2010 to June 2010. Data were collected through questionnaire interviews, focus group discussions and cross check interviews. Average yearly collection of mud crabs in this area was about 890.36 tons where lower grade crabs 45.16% and these can be brought under culture practice. It has observed that saline water intrusion was evident 670 Ha. In Hatiya and vast inundated area with saline water was found in Nijhum Island. Overall waiter salinity range was between 2-10 ppt., pH range of 7.8-8.6 and the soil was silt-loamy. The average temperature of the last three years was approximately 26.10 degrees C and rainfall was almost 10.85 mm. It was observed that natural feeds were available in this study area and there was existed a small potential marketing channel with 3-4 middlemen. Also there was a good transportation system both water and road way. So, present study revealed that the area is suitable for crab culture during April to October.
