Parasitism is discussed in the first section of this program with a comparison of predatorprey and parasite-host relationships. Students will get an understanding of the flea's habits, anatomy and behavior. The structure of bacteria, single-celled organisms, is given in the second section of this program. A comparison of aerobic and anaerobic bacteria is discussed, as well as their harmful and beneficial functions. The last section of this program helps viewers understand what viruses are and how they can infect a host. The influenza virus is highlighted, providing a discussion of vaccination.
Worldwide, the list of mosquito-borne diseases is growing due to increased international travel, global commerce, and the clearing of new lands for human habitation. Mosquito-borne viral diseases include those that cause hemorrhagic fever and neurologic disease. West Nile virus, which was first detected in the Western hemisphere in 1999, is one of several encephalitic viruses that now appears to be endemic in the United States. The curious evolution of the once relatively innocuous infection of birds is now causing deaths in birds, horses, and man. The incidence and fatality rate of West Nile virus in the United States is comparable to that of St. Louis encephalitis virus. Other than the supportive care typically provided to encephalitis patients, no treatments are available for persons with symptomatic West Nile virus infection. Dr. Sanchez presents the compelling recent history of the identification of West Nile virus infection in humans in New York in 1999 and the spread of West Nile virus through the United States. Only four states in the continental US have not reported laboratory-confirmed cases of West Nile virus infection.
Learn why, how, where and when to collect insects. The featured expert identifies necessary equipment and demonstrates techniques for using it to obtain insects. Viewers also learn humane killing techniques; how to preserve specimens in alcohol, on slides and on pins; how to use spreading boards; to enter data; and recommended storage containers.
Focusing on the scope and role of insects in the animal kingdom, the educational program provides viewers with the knowledge to enable them to identify and classify hundreds of insects. The instructor explains the purpose and work of entomologists and the importance- both beneficial and destructive- of insects within the environment. The expert demonstrates how to use characteristics and structures to identify insects for up to four classification levels. He uses both the pictorial and dichotomous taxonomic keys to identify insects.
Although pesticides are valuable allies in the control of pests that destroy crops, we don't want to exchange this benefit for environmental damage through their use. In the presentation you will explore the types and uses of pesticides, handling procedures (such as label contents and poisoning first aid) and caution around nontarget organisms, such as beneficial crop insects. Also discussed are laws, regulations and warnings (verbal and posted) that should be followed when applying pesticides.
See how and why IPM was developed in agriculture. Learn the basic strategies, proper pest identification, monitoring, biological control, physical control and chemical control. Explore various cultural control techniques such as sanitation, cultivation and the use of cover crops. Concepts such as the use of a crop's economic threshold are also shown. See how these strategies are effectively applied in orchard production, field crop production, strawberry production and vegetable production
See how to apply a detailed pest monitoring program to effectively coordinate physical, biological, cultural, horticultural and chemical controls in greenhouse crops. Learn how to reduce costs, increase safety and improve pest control in production greenhouses.

There are no easy answers to the issues surrounding the use of pesticides in agriculture, but the presentation will help you understand the differing viewpoints. Begin with historical methods of pest control and uses of pesticides. Then, review the environmental issues in the past three decades leading to current reexamination of pesticide application and risk. Candid interviews help expose the complexity of the issues. The DVD should be included in every ag-science curriculum.
Investigate whether your plant problem is best solved by the use of a herbicide (kills weeds), a fungicide (prevents or helps cure plant diseases) or an insecticide (kills or repels insects). Emphasis is placed on carefully reading the pesticide label for warnings, toxicity and precautions; wearing the proper safety gear; correct mixing and application techniques; and proper storage and disposal.
See how to integrate biological, cultural, physical, horticultural and chemical strategies into an effective pest management program. Explore how the basic IPM strategies are effectively applied in various landscape situations and how an individualized IPM program can be set up. Then visit various settings where IPM is used, including home gardens, Disneyworld's Epcott Center and San Francisco's Conservatory of Flowers.
An excellent introductory program into the lifecycle of insects and spiders and the way in which survival of the species is ensured. It has four main sections: the lifestyle, how insects obtain energy, how insects protect themselves and protection for the young. Insects have an amazing array of methods to ensure their survival from odours, poisons, stings, mimicry, camouflage and unique self made "buildings". Those with physical characteristics and behaviour that are suited to their environment will survive.

This is a short program on Bed Bugs and how they could affect hotels, college dorms, homes, and other locations throughout the world. The purpose of the video is to educate everyone about bed bugs and how to eliminate them.
Topics included in this safety video are: bed bugs, where are they, detection, how to get rid of bed bugs, more info on the bugs, domestic treatment, sanitation, and traveling.
Killer Bees, Wasps, And Spiders - Killer Bees, Wasps, and Spiders is the title of the program, but it's more than that. It's information and the proper protection to make sure you're prepared for an encounter with bees, wasps, and spiders. The most important fact to take with you today is not to panic when you're faced with a potential bite or sting. There's no need to panic because death rarely happens and armed with factual information, the chances are even less likely a death or serious injury will occur.
The Mosquito - What You Need To Know - This program has been developed to give you the information you need to protect yourself from being bitten by the mosquito and how to identify and eliminate the area's where they breed and multiply.
Topics included in this safety video are: 80 species of mosquitoes, symptoms of West Nile virus, where are the most common places mosquitoes breed and multiply?, what you can do to assist the metro health team, tips on protection, the use of repellants with DEET, safety precautions and kids, what metro health is doing to help protect you.
