ROMO LOZANO, J. L.; GARCIA JIMENEZ, J.; CIBRIAN TOVAR, D.  and  SERRANO GALVEZ, E.. ECONOMICANALISYS FOR BILOLOGICAL CONTROL OF EUCALYPTUS PSYLLID IN MEXICO CITY. Rev. Chapingo ser. cienc. for. ambient [online]. 2007, vol.13, n.1, pp.47-52. ISSN 2007-4018.

The psyllid Glycaspis brimblecombei Moore, is a threat for millions of eucalyptuses distributed within the country, whose death would represent the loss of an economic value which includes two main components: commercial benefits and benefits derived from the environmental functions. This makes interesting to carry out the economic analysis on the several alternatives of biological control, which are: parasitoids, predators and pathogens. Other control measures are the chemical control, and the option of making nothing. The main objective of this research was to analyze and compare the structure of costs for several alternatives of control. The methodology was basically to build scenarios corresponding to each control type by consulting experiences and researches on the matter and collecting information by direct interviews to experts. Results indicate that the control program with parasitoids is highly profitable with a benefit-cost ratio of 593.43 for the pessimistic expectation. This implies the avoided cost of removing around 620,373 dead alignment trees within Mexico City.

Keywords : Psyllaephagus bliteus; Glycaspis brimblecombei Moore; and Benefit-cost.
