Insecticides

What is the purpose of using insecticides?

• To promote insect growth

• To attract insects

• To provide food for insects

• To control, repel, or kill insects

Name one common type of insecticide used in agriculture.

• Pyrethroids

• Carbamates

• Neonicotinoids

• Organophosphates

How do systemic insecticides work?

• Systemic insecticides work by emitting ultrasonic waves that deter insects.

• Systemic insecticides work by being absorbed by plants and distributed throughout their tissues, poisoning insects that feed on the plant.

• Systemic insecticides work by repelling insects with strong odors.

• Systemic insecticides work by physically trapping insects in a sticky substance.

What are the potential risks associated with using insecticides?

• Increased crop yield, improved soil health, reduced pest damage

• Environmental pollution, harm to non-target organisms, development of insecticide resistance, and human health risks.

Explain the difference between contact and systemic insecticides.

• Contact insecticides are only effective on pests above ground, systemic insecticides only work on pests below ground.

• Contact insecticides are absorbed by the plant, systemic insecticides act on the surface.

• Contact insecticides act on the surface, systemic insecticides are absorbed and distributed throughout the plant.

• Contact insecticides are used for soil treatment, systemic insecticides are used for foliar application.

What is the role of neonicotinoids in insecticides?

• Neonicotinoids are used as fertilizers in agriculture.

• Neonicotinoids are only harmful to mammals.

• Neonicotinoids have no impact on insect populations.

• Neonicotinoids act as neuro-active insecticides by affecting the central nervous system of insects.

How can overuse of insecticides impact the environment?

• Insecticides promote biodiversity

• Insecticides have no impact on the environment

• Insecticides help reduce pollution

• Insecticides can harm non-targeted species, disrupt ecosystems, contaminate water sources, and lead to insecticide-resistant pests.

Discuss the importance of following safety guidelines when using insecticides.

• Ignoring safety guidelines is more effective

• Safety guidelines are only for professionals

• Insecticides are harmless to humans and pets

• It is important to follow safety guidelines when using insecticides to prevent harm to humans, pets, and the environment.

What are some alternative methods to chemical insecticides?

• Biological control, cultural control, mechanical control, organic insecticides

• Genetic modification, Ultrasonic devices, Pesticide spraying

Why is it important to rotate insecticides to prevent resistance in pests?

• To save money by using the same insecticide continuously

• To prevent pests from developing resistance by exposing them to different active ingredients.

• To reduce the effectiveness of insecticides by mixing different active ingredients

• To make pests stronger by exposing them to the same active ingredient repeatedly
