NOTE

PESTS AND VECTORS CONTROL

Pest

A pest is any organism, typically an animal, insect, or plant, that negatively impacts human activities, agriculture, or natural ecosystems. Pests can cause damage by feeding on crops, spreading diseases, or competing with native species for resources. Here are key points about pests:

Types of Pests

The following are the types of Pests.

  - Insects: Aphids, locusts, mosquitoes, and beetles.

  - Animals: Rodents like rats and mice.

  - Plants: Weeds that compete with crops for nutrients, water, and sunlight.

  - Microorganisms: Fungi, bacteria, and viruses that cause plant diseases.

Impact of Pests

  1. Pest destroy crops, leading to reduced yields and economic loss.
  2. Pest can infest homes and buildings, causing structural damage.
  3. Some pests, like rodents and cockroaches, can spread diseases to humans.
  4. Pest can disrupt ecosystems by outcompeting native species.

Vector

A vector is an organism that transmits pathogens from one host to another, spreading diseases. Vectors are often arthropods such as insects and ticks, but they can also include other animals. Key points about vectors include:

Types of Vectors

  - Mosquitoes: Transmit diseases like malaria, dengue fever, Zika virus, and West Nile virus.

  - Ticks: Transmit Lyme disease, Rocky Mountain spotted fever, and other tick-borne illnesses.

  - Fleas: Known for spreading the plague and typhus.

  - Sandflies: Transmit leishmaniasis.

  - Tsetse Flies: Transmit African trypanosomiasis (sleeping sickness).

Control Measures Against Pests and vectors

Control measures against pests and vectors is crucial for preventing the spread of diseases

  1. Use of insecticides, herbicides, rodenticides and fungicides to kill or repel pests and larvicides to kill larvae. Care must be taken to use them safely and avoid resistance.
  2. Introducing or encouraging natural enemies of pests, such as ladybugs to control aphids or predatory insects to control caterpillars.
  3. Using traps to capture and kill pests.
  4. Installing physical barriers like nets or fences to prevent pest entry.
  5. Trimming vegetation and clearing bushes to reduce resting sites for vectors like ticks and mosquitoes.
  6. Use of insecticide-treated bed nets (ITNs) or long-lasting insecticidal nets (LLINs) to create a physical barrier and prevent mosquito bites, particularly during sleep.

EVALUATION: 1. Differentiate between pest and vectors

  1. Mention 4 impact of Pests
  2. Identify 4 preventive measures against pest and vectors

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
