Pesticides are chemicals that are often sprayed on crops to kill plant-eating insects, preventing damage to the crops. While pesticides are effective initially, many researchers claim that any single pesticide will see reduced effectiveness in as little as ten to fifteen years.

Question

Which of the following best supports the claim by scientists that the pesticides will eventually lose their effectiveness?

The insects will build up a tolerance to the pesticides, and eventually the pesticide will not affect them.

The pesticides will increase the mutation rate in the insects, resulting in higher genetic diversity and higher survival rate.

Insects that are naturally resistant to the pesticide will survive and reproduce more than the insects that are sensitive to the pesticide.

Insects will evolve to avoid any plant sprayed with pesticides to increase their chances of survival.

You're growing cabbage and have noticed your plants have lots of insects and disease. Explain how you could use integrated pest management to help your crop be successful (either for the current season or in the future).
A farmer uses a new pesticide. He applies the pesticide as directed by the manufacturer and loses at 15% of his crop to insects. A farmer in the next state learns of these results and uses three times as much pesticide and uses only 3% of her crop to insects. Each farmer follows this pattern for 5 years. At the end of 5 years, the first farmers is still losing about 15% of his crop to insects, but the second farmer is losing 40% of her crop to insects. How can these observations be interpreted on the basis of natural selection? please answer short
How is integrated pest management (IPM) different from other forms of pest control? O IPM only supports mechanical control of pests in an area. O IPM tolerates a low number of pests in an area. O IPM favors the generation of herbicide-resistant weeds. O IPM prohibits the use of herbicides in an area. O IPM suggests the use of herbicide-resistant plants.
Which of the following does NOT describe an externality? A: A flower farm is located in a semi-urban part of town. The flowers attract pollinators that help nearby farms but also provoke allergies for some of the local residents. B: A cranberry farm releases acidic water into a nearby river that is an important habitat for many native species. C: A firm voluntarily adopts a new technology that reduces how much pollution it emits into the air, resulting in cleaner air for everyone. D: An industrial-scale farm uses high amounts of pesticides which reduces the farm’s ability to produce food over the longer term.
Explain why biologists such as David Pimentel believe that synthetic pesticides have been ineffective in reducing U.S. crop losses due to pests and believe that alternative pest management practices are preferable.
The Colorado potato beetle has a history of pesticide resistance. The graph shows the number of chemical insecticides used in agriculture that the Colorado beetle population has become resistant to from 1950 to 2010. It took longer for the population of potato beetle to develop a resistance to some insecticides. However, by 1990, the Colorado potato beetle population had developed a resistance to 35 different kinds of insecticides, and farmers ran out of insecticides they could use to control the beetle population. A new type of insecticide was introduced in 1995. 60 40 30 20 10 1960 1970 1980 1990 2000 Year of Report Which of the following best describes what happened from 1965 to 1975 and again from 1995 to 2000 to the insecticide resistance of the beetle population? The Colorado beetle gene pool for insecticide resistance was identical and the insecticide had no effect on the beetle population, which is why it continued to increase. The introduced insecticides were effective for a…
Farmers often face a predicament, known as the pesticide treadmill, in which the cost of applying pesticides increases because the pesticides have to be applied more frequently or in larger doses, while their effectiveness decreases. Based on what you have learned in this chapter, offer an explanation for why the pesticides lose their effectiveness.
Integrated pest management deals with the prevention and suppression of harmful organisms and long-term effects on the environment. Good agricultural practices in plant protection include weed control. Why is weed control important to agriculture production? A) weeds compete with crops for nutrients B) weeds compete with crops for moisture C) weeds compete with plants for sunlight D) weeds compete with plants and crops for nutrients, moisture, and sunlight
Treehoppers have a major predator, the jumping spider. Researchers hypothesized that the ants would protect the treehoppers from the spiders. In an experiment, researchers followed study plots with ants removed from the system and compared them to a control plot. Which of the following is consistent with the results shown in the graph? 100, Plants with ants 80- 60 408 Plants without ants 20 20 25 30 10 15 July August O Ants reduce the numbers of treehoppers. O Ants do somehow protect the treehoppers from spiders. O Spiders eat treehoppers when ants are present. O Treehoppers do not produce honeydew in July and are not protected by the ants. O Ants eat the honeydew produced by treehoppers. Average number of young treehoppers per plant

If you were to grow a Venus fly trap and provide it with a standard dose of chemical fertilizer, how would the abundance of traps change? Why? Increase because fertilizer helps plants grow larger Decrease because the plant doesn’t need traps to obtain these nutrients anymore Increase because now the plant will have an increased need for animals as food Decrease because the plant knows you will keep on fertilizing it
