An exploration of the potential benefits of integrated pest management systems and the use of insect resistant potatoes to control the Guatemalan Tuber Moth (Tecia solanivora Povolny) in Ventaquemada, Colombia AgEcon
Falck-Zepeda, Jose Benjamin; Barreto-Triana, Nancy; Baquero-Haeberlin, Irma; Espitia-Malagon, Eduardo; Fierro-Guzman, Humberto; Lopez, Nancy.
CORPOICA and IFPRI implemented a research project in Ventaquemada, Colombia. The project’s goal was to asses the benefits of Integrated Pest Management (IPM) practices and the potential of Genetically Modified insect resistant (Bt) potatoes to manage damage caused by the Guatemalan Tuber Moth (Tecia solanivora Povolny). The Guatemalan Tuber Moth is particularly destructive because field spraying on the adult stage is ineffective and there exists damage specificity to the tubers. Excessive pesticide sprays have resulted in resistance to several insecticides. Insect resistant (Bt) potatoes has been shown an effective means to control other members of the Tuber Moth complex. Thus a Bt potato may play a role in managing Tecia in Colombia. This is an ex ante...

Betting on cotton: Potential payoffs and economic risks of adopting transgenic cotton in West Africa AgEcon
Falck-Zepeda, Jose Benjamin; Horna, J. Daniela; Smale, Melinda.
Cotton is the largest source of export receipts in several West African nations where yields are declining and pesticide use is rising. Although there may be payoffs to introducing genetically modified Bt (Bacillus thurigiensis) cotton, limited information is available to predict its potential economic impact and there is uncertainty about its performance. Recognizing these constraints, we use an economic surplus model augmented with stochastic simulation to estimate ex ante the impact and distribution of benefits from Bt cotton. We consider the effects of adoption on both yields and abating crop damage, and offer scenarios depicting the policy options faced by West African stakeholders. The findings indicate that although the total net benefits of...

Distribution of Benefits and Adoption of Bt Cotton in Pakistan: Ex-ante Analysis AgEcon
Nazli, Hina; Sarker, Rakhal; Meilke, Karl D.; Orden, David.
This poster presents the potential impact of Bt cotton adoption in Pakistan. The size and distribution of economic benefits from the commercial adoption of Bt cotton in Pakistan are examined under four hypothetical scenarios. The adjusted economic surplus model is used to measure total benefits and their distribution between producers, consumers and technology innovators. To account for uncertainty in key parameters, the stochastic simulation techniques is applied. The results show that the total net benefits of adopting Bt cotton in Pakistan are large. As a result of increase in production, farmers get considerable benefits despite a decline in price. The share of benefits to innovators is small. The results indicate that the total cost of adopting latest...
