Expert Verified | Ace the Test
History of Pests - 🧠 ANSWER ✔✔- Black Plague: 14th century, Bacteria
- Irish Potato Famine: 19th Century, Fungal Disease
- Malaria: WWII 500,00 soldiers infected, 60,000 died, 2010: Malaria cases
were 219 Million Globally > mosquito nets & insecticide treatments
- Native Mountain Pine Beetle: Canada & United States, 4 million acres of
pines destroyed
- Pests have been around since the beginning of Human Civilization
,What is a Pest? - 🧠 ANSWER ✔✔An undesirable Organism that injures
humans, desirable plants, animals, manufactured goods, and/or
substances
Pest Control Throughout History - 🧠 ANSWER ✔✔- Rudimentary Controls:
pulling weeds, killing animals, burning plants to reduce insects (950 B.C.)
- Egyptians: Fish nets over cups to prevent mosquito bites (440 B.C.)
- Romans: rat-proof grain storage (13 B.C.)
- Sumerians: Earliest chemical control recorded, sulfur to control mites
(2500 B.C.)
- Chinese: mercury & arsenic (500 B.C.), mainly used for lice
- Early Plant Derived Control:
- Hellebore > lice
- Nicotiana (Tobacco) > aphids
- Chrysanthemum (Pyrethrins) > insects
- France 19th Century: lime & copper sulfate sprayed on grapes originally
to deter people from eating them, farmers realized that the treatment
,controlled Downy Mildew, still a widely used treatment > no resistance
showing today
- WWII: DDT given to soldiers, saved thousands of lives from insect bites,
beginning of modern chemical pesticides
What is a Pesticide? - 🧠 ANSWER ✔✔- Any material that is applied to
