The pink hibiscus mealybug (Maconellicoccus hirsutus) was detected in 1999 in Mexicali, Baja California, Mexico. The pest has been confined to an urban area adjacent to the border strip with United States thanks to the application of the National Emergency Mechanism establishing cultural, physical, legal and biological control measures. Surveillance and sampling activities also took place in states with risk of pest introduction, to confirm pest absence.

In February 2004, an outbreak of Maconellicoccus hirsutus was confirmed in teak (Tectonia grandis) in the municipality of Bahia de Banderas, State of Nayarit. Teak is an introduced forest species in this state. Extensive surveillance of the area allowed delimitation of the presence of the pest in the areas of El Porvenir, San Vicente, Valle de Banderas, San Jose, San Juan de Abajo and Colomo. The total infested surface is 63 ha. On February 20 of this year, Mexico started the application of the National Emergency Mechanism in order to confine and eradicate the outbreak of M. hirsutus in this region. The origin of the outbreak appears to be the introduction of infested ornamental plant products in tourist’s luggage.
