RESEARCH GAPS IN INSECTS AND DISEASES OF BLACK PEPPER (Piper nigrum): A REVIEW (Pages : 44 - 52)

Black pepper (Piper nigrum) is economically high-ranking and the most widely used spice crop around the globe including Bangladesh. The objective of this study is to document the research gaps in insects and diseases of black pepper in Bangladesh with other growing countries. The article is based on mostly existing literature and partly field observation from Sylhet region in Bangladesh. So far, many research works were done on these issues but all are not available to the policy makers, extension workers and public in a systematic manner to date. In the black pepper growing countries, major insects are pollu beetle (Longitarsus nigripennis), scale insects (Lepidosaphes piperis and Aspidiotus destructor), top shoot borer (Cydia hemidoxa), leaf gall thrips (Liothrips karnyi and Gynaikothrips uzeli), and root mealy bugs (Diconocoris hewetti) and pepper whitefly (Aleurodicus disperses) and major diseases are root rot (Fusarium solani), yellow wilt (Fusarium oxysporum), nematode (Meloidogyne incognita and Meloidogyne javanica), stunt disease were reported. On the contrary, leaf blight (Colletotrichum gloeosporioides) and algae leaf spot (Cephaleuros virescens), foot rot (Fusarium solani), wilt diseases and flea beetle, ant (Tetramorium spp.), pepper white flies, spiders were reported in Bangladesh. In addition, quick wilt and slow decline infection as well as top shoot borer and pollu beetle infestation like symptoms were also observed which requires further confirmation. It is noted that, black pepper growers in Bangladesh have no idea on the insects and diseases attack and their appropriate management which hinders expansion of area and production of black pepper in Bangladesh. More attention is required for proper management of insects and diseases of black pepper in Bangladesh. Hence, direct field observation on insects and diseases of black pepper is ongoing in the black pepper germplasm centre situated in Tilagorh Eco-Park of Sylhet and agroforestry field laboraDownload
