Answer 2

1. Prevention
2. Identification
3. Monitoring
4. Thresholds
5. Treatment
6. Evaluation

Question 3

Prevention

Answer 3

-Select resistant plants
-Manage growing conditions
-Eliminate food sources
-Prevent access

Question 4

Identification

Answer 4

Is there a pest problem and which pest is causing the damage? Learn about the pests biology

Question 5

Do you know the…

Answer 5

-Name of the pest
-Life cycle
-Best time to treat
-Number of treatments needed
-Beneficial organisms related to pest

Question 6

Monitoring

Answer 6

Provides detailed information about pest population. Make sure to take records of counts and observations

Question 7

Things to check for in monitoring

Answer 7

-Damage
-Pest count
-Weather conditions
-Pest’s life stage
-Host’s stage
-Beneficial organism presence

Question 8

Visual inspections

Answer 8

A careful look for signs of pest problems or conditions that promote pests. Done regularly

Question 9

Counting and measuring

Answer 9

Provides more numerical information about pest populations and the levels of damage

Question 10

Determine number of samples needed

Answer 10

Take average of sample of 10 then compare it to the average of a sample of 40. If they are within 10-20% then we can use the smaller sample

Question 11

5 indicators a visual inspection looks for

Answer 11

1. Presence of pest and beneficial species
2. Damage
3. Growing conditions
4. Plant health
5. Conditions that attract pests

Question 12

Injury & action thresholds

Answer 12

Interpreting information and making appropriate decisions

Question 13

The injury threshold

Answer 13

The point where a pest causes unacceptable injury or damage. Justifies treatment

Question 14

The action threshold

Answer 14

The point at which treatment should be started to prevent the pest population from reaching the injury threshold

Question 15

Treatment

Answer 15

The decision has been made to treat and manage a pest problem

Question 16

Cultural treatments

Answer 16

Treatments that can prevent pests from developing or spreading. They attempt to disrupt the pest life cycle or make the environment less favourable

Question 17

Mechanical/physical treatment

Answer 17

Mechanical or physical treatment involves the use of equipment, barriers etc. to prevent the spread or to reduce populations

Question 18

Biological treatments

Answer 18

Uses a natural enemy of the pest to reduce population. Eg. releasing a predator or using grazing animals to control weeds

Question 19

Behavioural treatment

Answer 19

Takes advantage of a pests biology and to manage the population. Eg. releasing sterile male insects or synthetic pheromones

Question 20

Chemical treatment

Answer 20

The use of pesticides

Question 21

Evaluation

Answer 21

At the end of the treatment process you evaluate if the results were good
