B Correct answer
Explanation

An herbicide is a pesticide used to kill or control unwanted plants, commonly known as weeds.

Multiple choice
  1. nonchemical

  2. chemical

  3. biological

  4. spraying oils

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Integrated Pest Management (IPM) prioritizes nonchemical methods, such as cultural and biological controls, as the first line of defense before resorting to chemical pesticides.

Multiple choice
  1. it is more costly

  2. it is less sustainable

  3. it is more sustainable

  4. it is very unpredicatable

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Biological pest control uses natural predators and parasites to manage pest populations, which is more sustainable than synthetic pesticides that can harm non-target species and lead to chemical resistance.

Multiple choice
  1. they kill more crop-eating insects than pesticides do

  2. their bites are the most dangerous threat to animals

  3. their webs in farms and sheds destroy farm equipment

  4. they are a threat to farmers because of where they nest

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Spiders are highly effective natural predators that consume vast quantities of insects that would otherwise damage crops. Their role in biological pest control is significant for agricultural productivity.

Multiple choice
  1. introducing nonnative pests to destroy them

  2. introducing natural predators to attack them

  3. introducing invasive pests to consume them

  4. create new species to combat them

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Biological control involves using natural enemies, such as predators or parasites, to reduce pest populations. Introducing nonnative or invasive species is generally discouraged as it can lead to ecological disasters.

Multiple choice
  1. expanding food supplies

  2. destroying the natural enemies of pests

  3. reducing pollution

  4. bringing nutrients back into the soil

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary goal of using pesticides in agriculture is to protect crops from pests, thereby increasing food supplies and preventing yield losses.

Multiple choice
  1. Bacillus anthracis

  2. Candida albicans

  3. Clostridium tetani

  4. Bacillus thuringiensis

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bacillus thuringiensis (Bt) produces toxins that are lethal to specific insect larvae, including butterfly caterpillars. The other options are pathogenic bacteria or fungi not used for this purpose.

Multiple choice
  1. Use of pesticide

  2. Natural predation

  3. Both

  4. None

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Organic farming relies on ecological balance and natural predation to manage pest populations rather than synthetic chemical pesticides. This approach promotes biodiversity in the farming ecosystem.

Multiple choice
  1. species-specific narrow spectrum pesticidal applications.

  2. species-specific broad spectrum pesticidal applications.

  3. species-specific narrow spectrum insecticidal applications.

  4. species-specific broad spectrum insecticidal applications.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Baculoviruses, specifically those in the genus Nucleopolyhedrovirus, are used as biological control agents. They are highly specific to certain insect species, making them narrow-spectrum insecticidal agents that do not harm beneficial insects or other organisms.
