Ecology/Taxonomy
The study of insects.
What is entomology?
Two characteristics of the Insecta class of the Arthropoda Phylum.
What are:
- 3 body regions
- 3 pairs of legs
- 1 pair of antennae
- Compound and simple eyes?
Two of the four categories of economically beneficial insects.
What is:
- Pollinators
- Decomposers & Nutrient Recyclers
- Predators & Parasitoids
- Commercial Insects?
The definition of ET and EIL.
What is:
EIL: The pest density at which the cost of control equals the value of crop loss.
ET: The pest density at which action should be taken to prevent reaching the EIL?
The purpose of Integrated Pest Management.
What is using common sense, scientific principles, and a combination of strategies to focusing on reducing insect pest damage to economically acceptable levels rather than complete eradication?
Two reasons why insects are important.
What are:
- they are pollinators
- good for experiments
- predate on insect pests/ parasitism
- food source for other animals on a higher trophic level
- they create products like silk, honey, wax
- etc...?
The class of arthropods with two body regions (Cephalothorax + Abdomen), no antennae, 4 pairs of legs, and a chelicerae + pedipalp.
What is Arachnida?
The difference between direct and indirect damage from economically harmful insects.
What is direct damage is caused by insect pests that feed directly on plants, reducing yield/quality, while indirect damage is caused by insect pests that vector plant pathogens/diseases?
The EIL calculation.
What is (EIL) = C/VIDK?
The five major types of pests.
What are insects, nematodes, disease, weeds and rodents/other animals?
A keystone insect species BESIDES thee honeybee and their ecosystem service.
What are examples like:
- Dung beetle: decomposition of organic waste
- Termites: decomposition of dead wood
- Moths: pollinators
- Mayflies: food source
- etc...?
Beetles pump their abdomens to move air through what external structures and inflate air sacs in the body.
What are spiracles?
The lower, fused structure that functions as a lower lip in many insect mouthpart types.
What is a labium?
The direction your ET should go if you are predicted to be underestimating your sampling?
What is lower/ a smaller ET?
Two types of biological pest management.
What are:
-Pathogens: Bacteria (i.e. Bacillus thuringiensis)
- Natural Predators: Ladybird beetles, mantids, lacewings
- Parasitoids: Parasitic wasps, beneficial entomopathogenic nematodes
- Allelopathy (phytoalexins for defense)?
A diagram that depicts the lines of evolutionary descent of different species from a common ancestor.
What is a phylogenetic tree?
The difference between MicroCT and Xray technology.
What is with 2D X-ray systems you can see through an object, but with the power of 3D micro- CT systems you can see inside the object and reveal its internal features?
The type of damage caused by aphids:
What is removal of plant fluids?
Three factors that can directly impact sampling efficiency.
What are:
- Repro rate
- Sampling efficiency
- Time to treat
- Stage of plant..?
Two considerations to remember with chemical pest control.
What are:
- Selective Application
- Thresholds
- Correct Timing
- Resistance Management?
All the major and minor taxa of Linnaeus's classification system.
What is:
- Domain
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species?
What organ allows many headless insects to still walk around and fly?
What is the fact that the nervous system, including the ganglion, are spread out collections of nerves that sense and control function in each segment of the beetle?
Six of the eight types of insect mouthparts.
What are:
Chewing (Defoliators, Fruit Borers)
Chewing-lapping (Nectar Feeding, Pollinators)
Rasping-sucking (Cell Damage, Distortion)
Piercing-sucking (Sap Removal, Disease Transmission)
Siphoning (Nectar Feeders, Pollinators)
Sponging (Liquid Feeders)
Cutting-Sponging (Blood Feeders)
No mouthparts (Non-feeding)?
The population model used to calculate ET.
What is ET * (1+r)^n = EIL?
An IPM plan that includes at least three different strategies to mitigate corn earworm in your field next year.
What are:
- Crop Rotation
- Parasitoids
- Bt/ Genetic Resistance
- Pesticides
- etc...?
