Classification and structure of insects & their functions


Assignment Task 1: Risk assessment & incident report

There are two (2) parts to this assessment.

Part A is a Case study. Read it carefully and then answer the below questions.

Part B is based on the Case study in Part A. You will have to carry out a risk assessment and complete a risk assessment form.

Part A: You are treating the exterior of the building of Mrs. Reti for spiders. You are using the power pump from your vehicle to apply the pesticide. Your vehicle is parked in the drive in front of the shop. Since you have finished the front of the building, you've asked that the children and the dog be removed from the back yard while you are spraying the rear of the building. All is well; Katie, Jimmy and the dog are having a great time out the front.

Suddenly you lose pressure in your hose and there is a huge commotion out the front. You can hear Jimmy screaming, the dog yelping and Mrs. Reti has come outside yelling. Some of the customers from her store are also rushing out to see what is going on. As you race around the corner to the front, to your horror you see what's happened. It appears that the dog 'Scratchy' mistook the hose for a long snake and attacked it, biting through the hose.

Scratchy got a big snout full of your spray mix and as Jimmy tried to remove the dog, he also got a mouthful and a good splash in the eyes. Pesticide is squirting in all directions and people are running around shouting.

Mrs. Reti has called an ambulance to take Jimmy to the hospital. A neighbor has kindly offered to take Scratchy to the vet.

Answer the following questions:

Question 1: Select a product that you were using (remember you were treating spiders), obtain a label and SDS for it and attach them to this assessment.

Question 2: List the information you will send with the ambulance to the hospital.

Question 3: Describe the steps you will take to handle the spilled pesticide on the driveway.

Question 4: Use the attached template to complete the incident report that you would submit to your company (and the relevant authority if required).

Assignment Task 2: Life cycles and harbourages

There are three (3) parts to this assessment:

Part A: you will have to prepare a written pest inspection report.

Part B: answer all the questions which are based on the: naming & classification and structure of insects & their functions

Part C: identification & treatments

Part A: You have been directed to provide pest identification details at the shop/dwelling of Ms Reti. She is particularly concerned with a range of pests that include cockroaches, spiders, ants, carpet pests, stored product pests and rodents.

You will need to prepare a written pest inspection report after your inspection. The report must include at least one (1) common species from each of the following groups: cockroach, spider, ant and rodent. (i.e.) you need FOUR (4) species.

The report must also include one (1) common species from at least one of the following groups: carpet pests (OR) stored product pests.

That totals to at least FIVE (5) species. For example, you may prepare your report using the following pests: German cockroach, Redback spider, Black house ant, House mouse and Indian meal moth

Use the attached tables as templates:

Species 1: Cockroach

Species 2: Spider

Species 3: Ant

Species 4: Rodent

Species 5: Carpet/Stored product pest

Part B:

1. Naming and classification:

a) All living organisms are classified according to structural characteristics at seven (7) different levels. Name the seven (7) levels.

b) There are certain rules when writing scientific names. What are these rules?

c) Write the scientific name for the American cockroach using these rules.

d) Is the following scientific name correct: Blattella Germanica? Explain the reasons for your answer.

e) If a scientific name was written as Musca sp., what does the sp. mean?

f) How many legs do the members of Class Insecta have?
