Science - The art of deriving sufficient conclusions from insufficient data.
(Study of the Universe)
Biology – Study of Life
Zoology – Study of Animals
Entomology – Study of Insects
Taxonomy is the science of naming organismsClassification
Leptinotarsa decimlineata Say
Principle Features of Phylum Arthropoda and Class Insecta
See lab manual for details
- takes little food to mature to reproductive age
Ability to fly
- escape enemies, adverse environmental conditions
- waxy layer, strong exoskeleton, jointed legs
High reproductive capacity
- e.g. CPB female can lay 3000 eggs
- adults and young use different resources
World-wide entomologists have described about 1 million species, systematists estimate between 2 and 10 million
There are about 100,000 species described in the U.S.
15,000 - 20,000 insect species in Minnesota
Q: How many (%) are pests?
< 1% are injurious - ca. 3,000 species worldwide
600 pest insectsin the United States
Injury to crops
DIRECT or INDIRECT injury
Injury to Humans and animals
Blood feeding - disease transmission
Internal & External Parasites
Injecting toxic substances
Destroy stored products and possessions
A living organism that occurs in such numbers and places so that it is inconvenient to human health, economics, comfort, or aesthetics.
- An insect which favorably affects humans
with the result of its actions or products.
Losses in Agriculture
Annual loss in the U.S. about $7 billion annually to insects
IPM - an ecologically based pest control strategy that maintains pest species below the economic injury level by use of the most appropriate and environmentally sound methods available.
The application of technology, in the context of biological knowledge, to achieve satisfactory reduction of pest numbers or effects.
