Dukeen Ahmed M. El Hindi Ahlam H. Ahmed Hmooda Toto CONTENTS: Fast Fact on Sudan, Principle Vectors of Disease & Distribution in Sudan, Multiple Preventions (Evidence-based & cost effective intervention), Vector Control Activities According to Stratification, The Current Vector Control Interventions (tools & methods used), Pesticide management practices, including policy and legislative frameworks, The status, quantities and management of obsolete pesticide stockpiles, current constraints and needs, The existing mechanisms for intersectoral collaboration on vector control. Fast Fact on Sudan: Location: G. coordinates: 15 000 N, 30 000 E, Population: 34,475,690, Area: . total: 2,505,810 sq km . land: 2,376,000 sq km . water: 129,810 sq km Climate: tropical in south; arid desert in north; rainy season (April to October), River Nile & tributaries: prominent feature. Vector Control Program Focus: Principle Vectors of Disease & Their Distribution in Sudan, The current vector control interventions (tools & methods); The pesticide management practices, The status, quantities & management of obsolete pesticide stockpiles (current constraints & needs); The existing mechanisms for intersectoral collaboration on vector control; Principle Vectors of Disease & Their Distribution in Sudan 1. Malaria Vectors : Anopheles arabiensis: all over country, arid zones, Anopheles gambiae: habitats, more humid & forested Anopheles funestus : habitat, more humid & forested Anopheles pharoensis & Anopheles nili: potential vectors Principle Vectors of Disease & Their Distribution in Sudan 2. Leishmaniasis Vectors : Phlebotomus papatasi: savannah & desert fridges Phlebotomus orientalis: Gedarif, Sennar, Blue Nile, Unity & Old Upper Nile States 3. Onchocerciasis Vectors : Simulum damnosum & S. surbanum: South west Sudan (Bahr El Ghazal & Bahr Al Arab mainly) & Abu hamad focus, Principle Vectors of Disease & Their Distribution in Sudan 4.Trypansomiasis Vectors (Gambiensis & Rhodesiensis): Glossina palpalis ,G.moristans & G. foscus: Mainly riverine & forest habitats in Southern Sudan, 5. Other vector-borne diseases: – Bancroftian filariasis : (mosquitoes), – Arboviruses: (mosquitoes mainly), – Other vectors/pests of PH importance: flies … The Current Vector Control Interventions (tools and methods used) Malaria & Other VBDs Control Malaria & Other VBDs Control is based on: a variety of strategies to respond to the epidemiological heterogeneity of the disease Malaria & other VBDs Burden in Sudan > 50% of malaria cases in EMR reported from Sudan The whole country is endemic with malaria All population at risk of malaria 80% of population live in epidemic-prone areas Annual records on malaria accounts for: - 7.5 - 8.0 million cases - 35000 deaths - Loss in working days - Treatment cost Other VBDs (Leishmaniasis, Onchocerciasis, A. Sleeping Sickness and recently Y.F. & D.F. Vector Control Management Strategies: IVM implementation: Main IVM components according to stratification: ITNs, IRS, chemical Larviciding environmental & IPT. Focus at present: ITNs & DDT alternatives on VBDs control Implementation limitations: budget availability Malaria Control annual budget ~ 3.2 million US$ . VC comprising ~ 1/3 of the overall budget, . Proportion of ann. local budget ~ 1.92 m US$ . Proportion of ann. Exter. budget ~ 1.28m US$ Monitoring & Evaluation Operational Research Multiple Prevention (Evidence-based & cost effective intervention): Scale up ITNs Expand IPT use Selective Vector Control Options based on local Epidemiological Stratification : IRS: Indoor Residual Spraying CL: Chemical Larviciding EM: Environmental Management SIT: Sterile Insect Technique Biological Control (BC) VECTOR CONTROL ACTIVITIES ACCORDING TO STRATIFICATION ITNs CL EM SIT LF (potential) IPT perineal (Intervention component) Irrigated Seasonal Urban Desert IRS stratification INTERVENTIONS INSECTICIDES RESISTANCE ASSESSMENT Summery Of Results: last update; 2006 Malathion : effective* all over the country except Kassala, GZR, KRT & SEN States Fenitrothion : effective* all over the country Deltamethrin : effective* all over the country Permethrin: effective* all over the country except KRT DDT : Effective all over the country except ; KRT,GZR, Kassala & States (restricted).

Product registered for commercial use; Registration System of Pesticides in Sudan: – Method of testing should follow the approved protocol; – Residues of the product tested in edible crops and/or the environment should be within acceptable limits; – Standard treatment (s) must be included in every field assay and the standard should be an already registered product; – Test products are only recommended if their biological performance is as good as or better than that of the standard products; Registration Chart Import & Formulation license Application for provisional registration (form 1) Review and recommendation by the Technical committee of the NPC Consider the recommendation of the Technical committee by the NPC Provisional registration Commercial registration (form II and IV) Approval of commercial registration by NPC Review of results of field testing by NPDC and recommendation for commercial registration Field testing for 3 months to 3 years (form III and V for importation of samples for testing) The Status, Quantities and Management of Obsolete Pesticide Stockpiles Summary of Quantities POPS Pesticides, Contaminated Soil & Containers in Sudan* Item POPS Pesticides (Tons) Contaminated soil (Tons) Containers (Tons) Total 229.445 8,860.51 528.84 In addition to 901 Tons of cotton seeds dressed with POPs Pesticides * Source: Multi-stake-holders National Coordinating Committee (MNCC) Inventory Report (2005) Quantities of Inventoried POPS Pesticides, Contaminated Soil & Containers Items in Different States of Sudan (2005) No. Site POPS Cont.soil (Ton) Containers (Ton) 1 2 3 4 Northern St. River Nile St. Khartoum St. 06.29 13.73 03.22 00.00 0203.10 0235.92 0016.80 0009.00 36.01 00.00 03.48 02.00 5 6 White Nile St. 04.18 Sennar & Blue 00.00 0396.40 1942.50 00.00 02.03 0005.00 0059.00 02.00 13.16 Gezira St. Pesticides (tons) Nile States 7 Red Sea St. 8.1 Kassala St. 00.04 58.82 Quantities of Inventoried POPS Pesticides, Contaminated Soil & Containers Items in Different States of Sudan (2005) No. Site POPS 8.2 Gedarif St. 8.3 9 10 11 12a Cont.soil (Tons) Containers (Tons) 00.00 008.00 01.00 (RAC.) 03.30 018.00 09.00 Bahr Eljabal State (Juba) W.
