It has brought together more than a hundred scientists from all over the world to discuss one of the world\u2019s most destructive agricultural pests, the <a href=\"https:\/\/greenmethods.com\/whiteflies\/\" target=\"_blank\" rel=\"noopener\">whitefly<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><figure id=\"attachment_7943\" aria-describedby=\"caption-attachment-7943\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/newint.iita.org\/wp-content\/uploads\/2016\/05\/1024_whiteflies-Large-population-of-B.jpg\" target=\"_blank\" rel=\"noopener\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-7943 size-full\" src=\"http:\/\/newint.iita.org\/wp-content\/uploads\/2016\/05\/1024_whiteflies-Large-population-of-B.jpg\" alt=\"Picture of Large population of B.tabaci adults feeding on the underside of a young cassava leaf.\" width=\"1024\" height=\"612\" \/><\/a><figcaption id=\"caption-attachment-7943\" class=\"wp-caption-text\">Large population of B.tabaci adults feeding on the underside of a young cassava leaf.<\/figcaption><\/figure><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In sub-Saharan Africa, whiteflies are a key threat to food security  and efforts to reduce poverty in rural areas as they destroy  and spread diseases in important crops of smallholder farmers such as vegetables, beans, cassava, cotton,  and sweet potato. The whitefly is the driving force behind the twin<a href=\"http:\/\/www.apsnet.org\/publications\/apsnetfeatures\/Pages\/cassava.aspx\" target=\"_blank\" rel=\"noopener\">cassava mosaic disease<\/a> (CMD)  and <a href=\"https:\/\/en.wikipedia.org\/wiki\/Cassava_brown_streak_virus_disease\" target=\"_blank\" rel=\"noopener\">cassava brown streak disease<\/a> (CBSD) p andemics that are currently ravaging cassava production in sub-Saharan Africa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, research on whitefly in the continent is inadequate. Apart from a lack of adequate funding, there are very few vector entomologists that could adequately manage the whitefly  and associated problems. Therefore scientists from Africa  and in particular Tanzania had an opportunity to learn from their colleagues from other countries such as the US, China, Europe,  and Australia on new  and innovative strategies to control the pest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the meeting chair, <a href=\"http:\/\/cassavawhitefly.org\/people\/65-peter-sseruwagi\" target=\"_blank\" rel=\"noopener\">Peter Sseruwagi<\/a>, from the Mikocheni Agricultural Research Institute (MARI), it was important to bring the symposium to Africa as the continent is currently grappling with how to feed its ever-increasing population in the face of the twin threats of shrinking agricultural l and  and climate change.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThis meeting brings together renowned whitefly researchers from over 24 countries, the private sector,  and students to share  and exchange the latest knowledge on the whitefly. They focused especially on CMD  and CBSD, the two viral diseases spread by whiteflies  and which have ravaged this key staple crop in sub-Saharan Africa,\u201d Sseruwagi said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The meeting\u2019s co-chair, <a href=\"https:\/\/iita.org\/fr\/legg-james\/\" target=\"_blank\" rel=\"noopener\">James Legg<\/a>, from IITA, added that \u201cAfrica is currently struggling with a wave of new viral diseases that are limiting the productivity of the poor smallholder farmers, who are a majority of the population  and are the main food producers. These farmers have limited resources to invest in inputs such as pesticides  and herbicides. We need to find sustainable science-based solutions to support them in tackling these challenges.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The symposium is co-organized by MARI  and IITA with the <a href=\"http:\/\/www.udsm.ac.tz\/\" target=\"_blank\" rel=\"noopener\">University of Dar es Salaam<\/a>, <a href=\"http:\/\/www.costech.or.tz\/\" target=\"_blank\" rel=\"noopener\">Commission for Science  and Technology<\/a> (COSTECH),  and the National Agricultural Research Organization (<a href=\"http:\/\/www.naro.go.ug\/\" target=\"_blank\" rel=\"noopener\">NARO<\/a>) of Ug anda.
