Which federal law requires pesticide applicators to follow label directions when applying pesticides near water bodies to protect aquatic ecosystems?
Answer: Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
FIFRA mandates that all pesticide use must comply with label directions, which include buffer zones and restrictions near water bodies.
Which arthropod-borne disease is transmitted exclusively by the Aedes aegypti mosquito in urban environments?
Answer: Dengue fever
Dengue fever is primarily transmitted by Aedes aegypti, which breeds in urban water containers and bites during the day.
What is the primary route of human exposure to organophosphate insecticides in agricultural settings?
Answer: Inhalation of vapor and dermal contact
Dermal absorption and inhalation of organophosphate vapors are the dominant exposure routes for workers in agricultural environments.
A community reports increased tick encounters after a local reforestation project. Which ecological factor most directly explains this increase?
Answer: Expanded deer and white-footed mouse habitat
Reforestation creates habitat for deer and white-footed mice, the primary hosts for tick populations, leading to tick population increases.
The EPA's pesticide registration process requires submission of which type of data to evaluate risks to non-target organisms?
Answer: Ecotoxicology studies
Ecotoxicology studies assess a pesticide's effects on birds, fish, invertebrates, and other non-target organisms as part of EPA registration.
Which practice best reduces insecticide resistance development in a vector control program targeting mosquitoes?
Answer: Rotating insecticide classes with different modes of action
Rotating insecticide classes with different modes of action prevents the selection pressure that leads to resistance in mosquito populations.
When assessing public health risk from a cockroach infestation in a food service facility, which factor is most critical?
Answer: Presence of allergens and potential pathogen dissemination
Cockroaches spread pathogens via their bodies and feces and produce allergens that trigger asthma, making these the critical public health concern.
