Pest Management

Pests are species that disrupt human welfare by competing for resources, damaging property, spreading disease, and invading ecosystems. To control pests, various methods are utilized, including chemical controls like pesticides, biological controls through predation, and physical removal strategies. Pests can also develop acquired resistance to chemicals, making management challenging. An effective approach is Integrated Pest Management (IPM), which combines chemical and biological methods for sustainable pest control. This ensures balanced ecosystems while protecting human interests.

  1. Pest Management 1/6/12

  2. What is a pest? • Any species that interferes with human welfare by competing with us for food, invading gardens, destroying building materials, spreading disease, invading ecosystems or being a nuisance.

  3. What are some ways to control pests? • Chemical controls= relies on synthetic chemical sprays • Pesticides: insecticides, herbicides, fungicides, rodenticides

  4. What is an acquired resistance? • Pests can build up an immunity to pesticides or evolve an ability to survive despite chemical application of pesticides.

  5. What are some ways to control pests? • Biological control= relies on predation, parasites or herbivory • i.e. Lady bugs and Lacewing (eat aphids), Bacillus thuringiensis (disease in caterpillers), parasitic wasps, chrysanthemumoil • Attraction methods: insect prefumes/pheromones, hormones

  6. What are some ways to control pests? • Physical controls = manually remove pests * Weeding a garden by hand • Other • Genetically modified organisms (GMO’s)

  7. What is integrated pest management? • Combination of chemical and biological controls to manage pests.
