• Habitat manipulation to mitigate the impacts of invasive arthropod pests (2010, background): “the intentional introduction of exotic natural enemies, has had some spectacular successes in controlling invasive pests (Zeddies et al. 2001; Menzler-Hokkanen 2006), but only about 10% of all introductions have contributed to management of the targeted arthropod”
• Novel Approaches for the Management of Mealybug Pests (2009, background): “t Rather few narrow host-range plant mealybugs are considered major pests on an international scale, as in the case of the cassava mealybug Phenacoccus manihoti Matile-Ferrero (Matile-Ferrero 1977 ; Neuenschwander 2001 ; Williams and Granara de Willink 1992 ; Zeddies et al. 2001) .”
• Economics and adoption of conservation biological control (2008, background): “In the latter case, Zeddies et al. (2001) estimated the benefit: cost ratio of this biological control program to be between 200 and 740.”
• The impact of integrated aquaculture-agriculture on small-scale farms in Southern Malawi (2010, background): “A number of studies assess the impact of agricultural research in SSA (Ahmed et al., 1994; Bokonon-Ganta et al., 2002; Masters et al., 1998; Rukuni et al., 1998; Zeddies et al., 2001).”
• Resources, Policies, and Agricultural Productivity in Sub-Saharan Africa (2013, background): “The efforts did not involve any conscious adoption decision by farmers or even require much scientifi c or technical capacity in cooperating countries (Zeddies et al., 2001).”
• Benefits and risks of exotic biological control agents (2011, unknown): “For the above mentioned example targeting the cassava mealybug P. manihoti, Zeddies et al. (2001) estimated the benefit to cost ratio of biological control in sub-Saharan Africa to be in the range of 200:1 to 740:1, depending on the market price used for cassava.”
• Fall armyworm [Spodoptera frugiperda (J.E. Smith)] damage in maize: management options for flood-recession cropping smallholder farmers (2019, background): “For example, Zeddies et al. (2001) reported a benefit: cost ratio 200 for the biological control of cassava mealybug (Phenacoccus manihoti) in SubSaharan Africa.”
