Biography

 I have completed post doctoral research work taking plant extracts and Inert dusts against stored-grain pests at Key Laboratory of Insect Resources Utilization and Sustainable Pest Management, College of Plant Science & Technology, Huazhong Agricultural University, Wuhan - 430070, Hubei, P.R. China, Since January 2007 to December 2009. Ongoing research on Application of Integrated Pest Management and Eco-friendly Management of Crop Production Reducing Environmental Pollution and Sustainable Development. I have completed five-year research programme taking Phytochemicals and Diatomaceous earth (DE) for the management of Stored-grain pest in Bangladesh, under the scholastic supervision of Dr. Md. Mahbub Hasan (mmhbgd@yahoo.com ), Professor Dept. of Zoology, University of Rajshahi, Banglades and finally got Ph.D. award. I have also completed one and half of a year research work taking synthetic and botanical pesticides and their comparison on stored-grain pests in Bangladesh in the laboratory of Entomology department, Bangladesh Agricultural University, Mymensingh under the scholastic supervision of Dr. Farid Ahmed Talukder (f.a.talukder@gmail.com ) in the year of 1995–1996 and got M.S.in Entomology degree. I have gathered Teaching and Research experiences twenty (20) years, supervise ten Masters, two M.Phil and two Ph.D. fellows, besides Entomology I have successfully conducting teaching classes on Plant Pathology, Genetics and Plant Breeding, Agronomy and Agricultural Extension at Under Graduate level.

Abstract

The rice weevil, Sitophilus oryzae is the most important and widely distributed throughout the world. It is one of the most notorious pest which cause heavy losses of stored grain both quantitatively and qualitatively throughout the world. The present study was designed to find out the effects of bio pesticide k-mite on the mortality of adult rice weevil, their progeny and repellency. The result showed that the highest mortality rate of S. oryzae adults using bio-pesticide (K-mite)at 15°C temperature was 40%, 76%, 94% in 3200ppm dose at 24H, 48H, 72H exposure periods respectively and the lowest was 2%, 10%, 23% in 50ppm doses at 24H, 48H and 72H exposure periods respectively. The result revealed that the highest mortality rate at 20°C temperature was 38%, 56%, 78% in 3200ppm dose at 24H, 48H, 72H exposure periods respectively and the lowest was 6%, 11%, 13% in 50ppm doses at 24H, 48H and 72H exposure periods respectively. The result noticed that the highest mortality rate at 25°C temperature was 45%, 67%, 82% in 3200ppm dose at 24H, 48H, 72H exposure periods respectively and the lowest was 3%, 6%, 10% in 50ppm doses at 24H, 48H and 72H exposure periods respectively. The result also showed that the highest mortality rate at 30°C temperature was 22%, 46% in 1600pp dose & 98% in 3200ppm dose at 24H, 48H, 72H exposure periods respectively and the lowest was12%, 33% in 50ppm doses at 24H, 48H and 72H exposure periods respectively. The repellent effect of bio-pesticide (k-mite) against the adult rice weevil S. oryzae, in R1, R3, R4 and R5 replications, 100% insects (Sitophilus oryzae) went to non-poisonous food. In R2 replication, 96% insects (S. oryzae) went to non-poisonous food and only 4% insects (S. oryzae) went to poisonous food.
