Question 1

Why are insects significant in public health?

Accepted Answer

They spread communicable diseases

Answer

Insects play a significant role in public health because many species act as vectors, transmitting pathogens that cause communicable diseases to humans and animals. Mosquitoes, for example, spread malaria, dengue, and Zika, while ticks transmit Lyme disease. Understanding insect biology and control is therefore crucial for preventing disease outbreaks and protecting public health.

Question 2

What is the impact of improper pesticide application on the environment?

Accepted Answer

Causes environmental contamination

Answer

Improper pesticide application, such as using excessive amounts, applying in windy conditions, or near water sources, can lead to significant environmental contamination. This includes polluting soil and water, harming non-target organisms like beneficial insects, birds, and aquatic life, and disrupting ecosystems. Adhering to label instructions and IPM principles is crucial to minimize these negative impacts.

Question 3

Which insect is a known vector of the Zika virus?

Accepted Answer

Aedes mosquito

Answer

The Aedes mosquito, particularly species like *Aedes aegypti* and *Aedes albopictus*, is the primary vector for the Zika virus. These mosquitoes acquire the virus by feeding on an infected person and can then transmit it to others through subsequent bites. Control of Aedes mosquito populations is therefore a key strategy in preventing the spread of Zika and other arboviruses.

Question 4

How can pest control support environmental sustainability?

Accepted Answer

Minimizing chemical use and using alternatives

Answer

Pest control supports environmental sustainability by adopting strategies that minimize harm to the environment while effectively managing pests. This involves prioritizing non-chemical methods like cultural and biological controls, using pesticides only when necessary and in targeted ways, and selecting products with lower environmental impact. This approach reduces pollution, protects biodiversity, and conserves natural resources.

Question 5

What public health risk is associated with cockroaches?

Accepted Answer

They transmit allergens and bacteria

Answer

Cockroaches are significant public health pests because they can transmit various pathogens and allergens. They often inhabit unsanitary environments, picking up bacteria like Salmonella and E. coli on their bodies and legs, which they then transfer to food preparation surfaces or directly onto food. Additionally, their droppings and shed skins contain allergens that can trigger asthma and allergic reactions in sensitive individuals, particularly children.
