Última The economic value of releasing parasitoid for the control of maize stemborers in East and Southern Africa AgEcon Kipkoech, Anderson Kipruto; Schulthess, Fritz; Yabann, Wilson K.; Maritim, Henry K.; Muchugu, Erick; Mithofer, Dagmar. The braconid larval parasitoid Cotesia flavipes Cameron was introduced from Asia into East and Southern African region starting in 1993 to control the invasive exotic maize stemborer Chilo partellus (Swinhoe) (Lepidoptera: Crambidae). A quasi-experiment was constructed using farmers that applied sublethal dosages of pesticide in assessing the counterfactual for the impact of the establishment of the introduced parasitoid in five countries in the region. Logistic regression method was used to estimate the probability that farmers’ would inadvertently exclude parasitoids in their maize field. Thereafter the propensity score matching method was used to find corresponding farmers excluding parasitoids among those who did not for yield comparison. The...
