Technical Abstract: A Pink Hibiscus Mealybug (Macconelicoccus hirsutus (Green)) was detected, in 2004, in Valle de Banderas, at municipalities Bahía de Banderas, Nayarit, and Puerto Vallarta, Jalisco, México, affecting fruit trees, native and ornamental plants. This pest insect is native to Asia and Australia, and has economic importance in several countries. The most common method to detect M. hirsutus in new locations consists of visual inspections on plants; however, with this method, the insect detection occurs once the infestation is already evident. An alternative method for detecting M. hirsutus could be the use of the attraction pheromone for M. hirsutus males, composed of lavandulyl and maconellyl esters. In this study, we evaluated the attraction effect of the Pink Hibiscus Mealybug pheromone in Valle de Banderas on a teak (Tectona grandis L.) plantation, on a natural stand of parota trees (Enterolobium cyclocarpum (Jacq.) Griseb.), on a mago tree orchard (Mangifera indica L. cv. Ataulfo) and on a guanabana tree orchard (Anona muricata L.). Furthermore, the pheromone was used to determine the insect geographic extent starting from the location of initial detection. We found that lavandulyl and maconellyl on a 1: 5 ratio significantly attracted M. hirsutus males and was very specific. By using this insect pheromone, we were able to map the extent of this species to a regional scale.
