What chemical gives the mothball smell?
The chemical that gives mothballs their distinctive smell is called naphthalene. When mothballs are stored, they release naphthalene vapors that repel insects.
Can viruses or insects live in rust?
No, viruses and insects cannot live in rust because rust is a type of corrosion that occurs on metals, particularly iron and steel, when exposed to oxygen and moisture. Viruses require a living host to replicate, while insects have specific habitat and food requirements that are not met by rust.
What is AZEK made of?
AZEK is made of a cellular PVC material that is engineered to be long-lasting, durable, and low-maintenance. It is comprised of a blend of plastic and resins, making it resistant to moisture, rot, and insects.
How do chemical fertilizers and pesticides affect the production in agriculture?
Positive Effects of Chemical FertilizersPlants require nutrients in the soil to grow and produce fruits and vegetables for consumption. These nutrients become depleted through overplanting, erosion and other conditions. Replacing these nutrients helps use soil and water resources efficiently. According to the International Fertilizer Industry Association, farmers can double or even triple crop yields by using fertilizers. Farmers also use manure products such as cow dung, pig excreta and chicken droppings to fertilize soil and increase yields.Negative Effects of Chemical FertilizersThough chemical fertilizers increase food production for nations all over the world, the negative effects to the environment have become inarguable. The chemicals that compose fertilizer, such as nitrogen and phosphorus, run off into local waterways during rainy periods. These chemicals cause algae blooms in the water which then die, increasing the bacterial content. This increase kills fish and disrupts the food supply of other animals that feed on the fish. Organic fertilizers do not contain these chemicals, therefore they do not produce this effect on the environment.Positive Effects of Chemical PesticidesFarmers use chemical pesticides to eliminate insects and diseases that destroy crops and diminish food supply. These compounds work very well in killing the insects that feed on the roots, leaves and stems of both food crops and garden flowers. Using these pesticides saves the crops that feed nations all around the world. They can often mean the difference between a healthy, expanding population and malnutrition and death.Negative Effects of Chemical PesticidesChemical pesticides are linked to a number of illnesses including cancer, lymphoma, reproductive abnormalities, endocrine disorders and neurological problems. According to ScienceDaily, scientists in a UCLA study have discovered links between Parkinson's disease and the use of two common pesticides, maneb and paraquat. Health experts are particularly concerned about pesticide exposure in children because they proportionally consume more food during their growing years and are often in contact with floor surfaces where pesticide residues are found. Pesticides also kill insects indiscriminately, destroying insects that are beneficial to plants and an important food source for other creatures. Some farmers are adopting more organic methods of pest control, such as introducing natural predators of the insects and using of plant extracts to repel insects. These methods reduce effects of pesticides on human health and the environment.

When was Pacific Insects Monograph created?
Pacific Insects Monograph was created in 1961.
When did Pacific Insects Monograph end?
Pacific Insects Monograph ended in 1986.
Humans have inadvertently promoted the evolution of insects that are resistant to insecticides by?
Insects became resistant because the insecticides were used on the continuously. Most insects will die at first, but there will be some that have the right genetics to resist that insecticide. When that happens the insect will the favorable gene reproduces and creates more insects that are resistant. Humans promoted this evolution by using the same insecticide on the insects.
Do grasshopper spread plant diseases?
Not normally as they are biting and chewing insects. Diseases are normally spread by sap sucking insects like Aphids
What are two bad things that insects do for us or to us?

What is using predators of insects and natural diseases to get rid of harmful insects called?
That would be called biological control of insects.
Why can insects adapt very quickly to pesticides?
inherited genes that made it resistant to the pesticide
What is an unintended consequence of using pesticide of plants?
The rise of pesticide-resistant insects.
Can Insects and animals can spread diseases?
Yes, some animals and insects can carry diseases in their blood, usually obtained from eating their prey that had it and transferring it to other animals and even humans.
