Farmers' Knowledge and Perception of Cocoa Insect Pests and Damage

The use of integrated pest management (IPM) tools is critical for effective pest management. Previous studies on Received: November 13, 2020 the subject have considered how farmers perceive the economic impact of insect pests on Accepted: December 23, 2020 cocoa. These studies however did not investigate farmers’ ability to identify pests, associ- ated damage symptoms and their implications for pest management. The current study, *Corresponding address: therefore, assessed farmers’ ability to correctly associate insect damage with the pest [email protected] species that caused it. A total of 600 farmers were interviewed in the Eastern, Ashanti, Western, Brong Ahafo and Central Regions of Ghana with a structured open and closed- ended questionnaire. Most farmers (>85%) were unable to correctly identify and associ- ate pests to their damage. The majority (>80%) of farmers also could not link the imma- ture stages of insect pests to their adult stages. -

Manual ICCO 2Nded Final[1]
Pesticide Use in Cocoa A Guide for Training Administrative and Research Staff 1st Edition: August 2008 2nd Edition: December 2009 (revised March 2010) Published online by: ICCO 6th Floor, Commonwealth House, 1-19 New Oxford Street London WC1A 1NU, UK www.icco.org www.dropdata.org/cocoa Sponsored by cocoa / chocolate industries under the auspices of the ICCO A Guide to Pesticide Use in Cocoa Foreword Recent changes to legislation in the European Union (EU) and Japan have concentrated minds over crop protection practices in cocoa and other commodity crops. From the 1st September 2008, assessment of the quality of cocoa imported into the EU included measurement of traces of substances that have been used upstream in the supply chain, including pesticides used on farms or in storage. The crop protection activities of farmers and middlemen will therefore be of increasing concern to all in the cocoa trade, some of whom may have a limited working knowledge of pesticide science. Pesticides have a poor public image and are known to present dangers to both people and the environment. Nevertheless cocoa, like other tropical crops, is often ravaged by insects, diseases and other pests that must be controlled effectively as well as safely. Pesticides can provide useful control solutions, but must be approved for use on the basis of Good Agricultural Practices (GAP). Unfortunately up-to-date GAP has yet to be established in many cocoa growing areas. This manual is designed to 1. Summarise important underlying administrative (Section A) and technical issues with pesticides. Sections B and C will be of particular interest to research and extension staff seeking more background information on pesticide science. -
Major Pests Situations on Cocoa in Togo
Major pests situations on cocoa in Togo Wegbe K. and Agbodzavu K. M. Nous assurons les bases technologiques d'un développement agricole durable Plan • Introduction • Insect pests • Diseases • Conclusion Nous assurons les bases technologiques d'un développement agricole durable Introduction • Cocoa: 3rd agricultural product exported after cotton and coffee. • It is grown in the south-west of the ‘‘ Region des Plateaux’’ by approximately 27,000 smallholders (DSID, 2001). • Between 1999-2000: contribution to Gross Domestic Product (GDP) was 0.4% in average (BDPA, 2000). Nous assurons les bases technologiques d'un développement agricole durable Introduction Today cocoa plantations are facing many constraints due to many factors: • Total liberalization of the sector in 1996 • No renewing of plantations ageing of existing plantations • Abandoned plantations • Decrease of soil fertility • Resurgence of pests and diseases Nous assurons les bases technologiques d'un développement agricole durable Introduction • Concerning the latter constraint, several insect pests and diseases are recorded in cocoa farms • Damages and losses they cause are hindering seriously the development of cocoa production in Togo Nous assurons les bases technologiques d'un développement agricole durable Insect pests in cocoa plantations I.

La présente étude vise à déterminer les périodes de fortes attaques de ce déprédateur dans la région du Haut-Sassandra, la deuxième plus grande région de production de cacao en Côte d’ivoire. Méthodologie et résultats : L’étude a été réalisée de 2009 à 2013 dans les plantations villageoises de la région du Haut-Sassandra en Côte d’Ivoire. Les variations des taux d’attaques d’ Eulophonotus myrmeleon ont été évaluées par dénombrement mensuel des trous récents dans six cacaoyères attaquées, choisies dans trois sous-préfectures, à raison de 2 par sous-préfecture.
