Pink hibiscus mealybug (Maconellicoccus hirsutus) is an important forest and urban plague in the countries it inhabits. This plague is characterized by its high polyphagia, and it is associated to 73 families and more than 200 genuses of plants.

By the threat caused by its appereance in Cuba, some researches were carried out in order to establish the scientific and methodological bases necessary to estimate the risk, and to develop a program to prevent and mitigate its impact.

Through some population surveys, it was confirmed the absence of this pathogen, and it was developed a method for its early detection. There were determined the taxonomical keys to identify those species.

It was designed a computarized system to determine impacts and to choose variants of prevention programs based on cost-benefit relation by cartographic quadrants.

It was created an instructive instrument to guarantee the quality of masive litters of Crytolaemus mountrouzieri imported predator. It was identified the parasitic community associated to mealybug in important cultivations and it was chosen Leptomastix dactylopii as promissory control with predator C. mountrouzieri. It was developed and introduced a methodology for the masive reproduction of these biological controls in the Vegetal Sanity System of the country.

The results were disclosed in events and gave rise to 13 articles in scientific magazines, 2 of these were published in very important magazines.
