The video begins by providing enough background information on the gypsy moth to allow those unfamiliar with the insect to understand the insect's importance. This information is developed logically, making it very easy to follow. A detailed description of the gypsy moth's life cycle follows. The life cycle is given in non-technical terms and includes information necessary to identify all life stages of the gypsy moth.
The next portion of the video addresses the issues involved in making a management decision, including land use objectives, tree health, and the consequences of quarantine. The tools used in detecting gypsy moth populations, including trapping and forest appearance are also discussed.
The final part of the video describes treatment options. Treatments range from no action to various pesticides to classical biological control. The majority of this discussion focuses on the advantages and disadvantages of each of the three natural pesticides registered against gypsy moth: Dimilin (insect growth regulator), Bacillus thuringiensis, and Gypchek (gypsy moth nuclear polyhedrosis virus). Treatments used against low level populations, such as pheromone traps and natural enemies, are mentioned only in passing.

The National Gypsy Moth Management Group in Landisburg, PA is a unique team of biologists, entomologists, and foresters. NGMMG has developed programs for counties, municipalities, universities, industries and community associations. These programs are based on a knowledge of the distribution, and health of the particular gypsy moth infestation, the objectives of the client, and selection of methods with the least environmental impact. NGMMG supervises its programs closely and educates the community to gain support and cooperation.
NGMMG produces parasitoids for release. However, they will not sell these parasitoids to individual homeowners, as these controls are not effective on a small scale. NGMMG also has a research branch, BioBase Technologies, Inc., which conducts studies for government and industry in the search for new rational ways of dealing with the gypsy moth and other pests.
Praxis in Allegan, MI also offers gypsy moth control programs for communities a "kit" that is specifically designed for a specific location based on information provided by the community. The Praxis program also stresses hands-on community involvement.
