Options for dealing with gypsy moth that will be discussed in detail at the meetings include:

— Taking no action,

— Using mass trapping, which involves setting a large number of traps in a concentrated area to capture male gypsy moths before they have a chance to locate and mate with females, or

— Using biological control, which involves the aerial application of the naturally occurring bacteria Btk (Bacillus thuringiensis var. kurstaki), which eliminates gypsy moth larvae, or

— Using mating disruption, which involves the aerial application of the gypsy moth mating pheromone (or scent) that confuses male gypsy moths and prevents mating, or

— Using integrated pest management, which involves the combined use of the above options.

Those unable to attend one of the public meetings may view the meeting’s PowerPoint presentation, a series of question-and-answer documents, as well as maps of the exact sites of concern and further information at
