What are the threats to food supply?

Pests can pose a serious threat to a food supply. A major food crop is corn, which supplies humans with food that we eat, food for animals, and corn ethanol used for fuel. There are many pests to corn, including vertebrates, invertebrates, weeds, and diseases.

What is pest control in agriculture?

Pest control in intensive agriculture involves pre- and postharvest treatment of crops with a variety of synthetic chemicals generically known as pesticides . Pesticides include herbicides and insecticides, which are mainly used in the preharvest stages; rodenticides, which are employed while storage of the crops; and fungicides, which can be applied at any stage of the process. Livestock can be contaminated through the consumption of contaminated feed and water, from pesticide application in animal production areas or from treatment of the animals themselves to prevent pest infestations. This can result in the presence of pesticide residues in animal-derived food products, and therefore, humans are mainly exposed to these chemicals through ingestion. The chronic effects of human exposure to pesticides from food intake are not completely defined, but there has been increasing evidence of carcinogenicity and genotoxicity, as well as endocrine disruption capacity (LeDoux, 2011 ).

How do pesticides work in agriculture?

Pest control in agricultural crops is generally achieved by chemical pesticid es which are effective and have a ‘knock-down’ effect on life stages of insects and mites. Recently, plant products have been experimented on in indoor cultivation and in fields.

A relatively standard part of pest control programs is the log containing all the relevant information about the program. Some information in the log is legally required, whilst other information is needed or required for the company’s own purposes and to satisfy external quality assurance programs.

Why do you need to treat perimeter trap plants?

The perimeter trap plants can then be treated to reduce the pest population there. Trap plants may be planted within a crop to be protected and act so as to lure the pest from the crop. The individual or patches of trap plants can be treated so as to destroy the pest species.

What is the purpose of using clean plant material?

Use of clean (disease and pest free) planting material (true seeds, seed tubers, and cuttings) is a prerequisite to control disease in the field and postharvest. For example, onion seeds are very often infected with molds (Snowdon, 2010 ), requiring a preplanting fungicide treatment.

Why is natural pest control important?

This focus is because promoting natural pest control could yield several important benefits, i.e., a reduced reliance on pesticide use, but also greater crop yields and increased biodiversity in agricultural landscapes ( Gagic et al., 2017 ).

What are the pests that humans have been able to control?

Humans have been managing agricultural pests for thousands of years. Pests can include weeds, plant pathogens (certain fungi, bacteria, and viruses), rod ents, and nematodes in addition to the plant-feeding insects and mites described in the preceding text, and are estimated to destroy as much as one-third of all agricultural yield. A wide array of pest control tools exist including cultural practices such as weeding, pesticide applications, and selective plant breeding for pest resistance.

Why are moths considered crop pests?

As noted earlier, many are migrants, preadapted to be crop pests (because they are highly dispersive insects that locate resources quickly and thrive in early successional habitats).

What is the name of the pest that attacks dog food?

A species, such as the Indian Meal Moth (Plodia interpunctella) (Pyralidae), are important stored product pests that attack grains, cereals, bird seed, dry dog food, and even candy that has sat too long.

How do abiotic factors affect insect pests?

Environmental favorability is influenced by abiotic factors that can affect a potential insect pest either directly via tolerance of physical, chemical, or climatic conditions, or indirectly through their influence on the nutritional quality of cultivated plants. For example, heavy rains not only lead to direct mortality of plant-feeding insects, but can also lead to improved host plant quality through the stimulation of plant growth. Similarly, environmental favorability is influenced by biotic factors that, in addition to host plant quality, include host plant abundance, activity of competitors and natural enemies, and disturbance from human intervention. Given the broad range of factors that contribute to environmental favorability, what evidence do we have that natural biological control ever plays a pivotal role in the suppression of potential agricultural pests?

What is an agroecosystem?

Agroecosystem. An ecosystem under agricultural management practices. Biocontrol. Control of agricultural pests by the use of predators and other beneficial organisms (e.g., control of turf grass crickets by parasitic nematodes).

Why are lepidoptera important?

Importance. Lepidoptera, in particular moths, are among the most important forest and agricultural pests. There is almost no plant tissue that is not eaten by one or more species of moths. Most of the forest pests are of cyclical occurrence with natural enemies eventually controlling population numbers.

How do farmers control pests?

One common alternative method used for controlling pests is biological control, which is when natural predators of the pest are introduced to prey on or parasitize the pest. When using this method, farmers get natural predators of the pest and release them into their fields so that the predators can manage the pest population.

What is the method of pest management where crops are genetically altered?

As agricultural technology has advanced, scientists have developed alternative methods of pest management that focus on the genetics of the organism. Genetic control is the method of pest management where the crops are genetically altered so that they are resistant to pests and diseases caused by pests. Crops can be genetically altered in ways that produce chemical or physical barriers to prevent harm from pests.

What is the alternative method of pest control?

This alternative method most commonly includes the use of pheromones or hormones to either attract and trap the pest or alter the functioning of the pest’s body. The last type of alternative pest control method is genetic control. Genetic control is the method of pest management where crops are genetically altered so that they are resistant …

Why were wasps introduced to the hornworm population?

The hornworm caterpillars were consuming the leaves of many crops, and the wasps were introduced to control the hornworm population. The wasps are parasites of the caterpillars. They lay their eggs in the caterpillar’s body. The wasp larvae hatch and use the caterpillar for nutrients and eventually cause the death of the caterpillar.

What are the chemicals used to control pests?

The other most common natural chemical control used is hormones .

Why is genetic control important?

Although genetic control has made it possible to reduce the damage done by pests , there are some concerns over changing the genetics of organisms.

What are the chemicals that control the growth and functioning of an organism?

The other most common natural chemical control used is hormones . Hormones are chemicals produced by an organism that control the growth and functioning of the organism. Hormones of pests have been extracted and synthesized and can be released into the environment.

How to control pests in agriculture?

Natural Pest Control Methods in Agriculture. There are several methods to control the pests naturally by using cultural and mechanical methods. Also, natural pesticides can aid in the control of these pests. The pesticides which are derived solely from natural products without using chemicals are called natural pesticides.

How to eliminate pests in the field?

Water is the greatest source to eliminate pests. Flooding water in the fields submerges the pests inhabiting the soil, and they flow away with water. Ex- Soil inhabiting pests like white grubs and cutworms can be eliminated through flooding.

Temperature inhibits the activity of pests by making them inactive. The high temperature through steam sterilization of greenhouse, hot water treatment of bulbs, hot air treatment of godowns can be used to eradicate the pests.

What is the purpose of pesticides?

Pesticides are the substances sprayed on plants to kill pests. Pesticides are both chemical and natural. Chemical pesticides compose of chemicals, and they are harmful in numerous ways. They affect beneficial insects and kill natural predators like honey bees.

Why are farmers using pesticides?

These pesticides are disturbing the ecosystem and are carcinogenic. To stay away from the effects of chemicals on human health, everyone prefers organic food, which is grown naturally without any chemicals.

What are the effects of pollen on humans?

They cause pollution, make the pollen sterile and show residual effect. These chemical residues enter the food chain and cause several disorders to humans like cancer, neurological disorders, Parkinson’s disease, asthma, headaches, vomitings, depression, and it may suppress the immune system.

Is there a single method of pest control that has ever been proven successful?

No single method of pest control has ever been proven successful to eradicate the pests. Using chemicals has shown adverse effects on humans and the environment. So natural methods must be adopted to eradicate the pests. These are ideal methods of controlling pests and are safe and less damaging.

What are some insects that control weeds?

Insects control weeds by feeding on plants or by transmitting disease organisms that injure plants. Moths, thrips, mealybugs, scale insects, wasps, certain beetles, leafminers, gall midges, and other insects have been moderately successful in biological control programs for weeds. Pathogens.

What is the use of microorganisms for the management of insects and mites?

The use of microorganisms for the management of insects and mites is a special category of augmentation. There are several microbial pesticides, including bacteria, fungi, viruses, and protozoa, currently registered for the management of insects and mites. For more on microbial pesticides, see p 87 in Chapter 3 of .

What happens when you mix pesticides in water?

If water used for mixing pesticides contains soil particles or other impurities, the effectiveness of the pesticide may be reduced. Chemicals in the water can alter the active ingredient of a pesticide, changing its toxicity or making it ineffective against the target pest.

Why is it so hard to apply pesticides?

The result of uneven distribution in clumpy soil is that pesticide will not reach the target organism and control will be reduced.

What is the difference between selective and nonselective herbicides?

Herbicides are organized in several ways, generally relating to how they affect plants or which types of plants they affect. Selective herbicides only kill certain types of plants (such as broadleaf or grass weeds); nonselective (broad- spectrum) herbicides kill all types of vegetation.

What crops can be rotated to reduce nematodes?

Rotating to a flooded crop, like rice , or a highly competitive crop, like alfalfa, can also help reduce a variety of troublesome pest species. Various crops can be used as part of a rotation sequence to reduce nematode and soil pathogens as well as provide additional benefits in broadleaf crops (Table 1-4).

What animals can be used to control weeds?

Among vertebrates, fish, birds, and mammals have the greatest potential for biological weed control. For instance, sterile grass carp can be used in certain well- contained water bodies to manage aquatic weeds. Geese have been used as selective grazers to control weedy grasses in cotton, orchards, and vineyards.



In agriculture, horticulture, and forestry

Biological pest control is a method of controlling pests such as insects and mites by using other organisms. It relies on predation, parasitism, herbivory, parasitody or other natural mechanisms, but typically also involves an active human management role. Classical biological control involves the introduction of natural enemies of the pest that are bred in the laboratory and released into th…


Pest control is at least as old as agriculture, as there has always been a need to keep crops free from pests. As long ago as 3000 BC in Egypt, cats were used to control pests of grain stores such as rodents. Ferrets were domesticated by 500 AD in Europe for use as mousers. Mongooses were introduced into homes to control rodents and snakes, probably by the ancient Egyptians.

In homes and cities

Many unwelcome animals visit or make their home in residential buildings, industrial sites and urban areas. Some contaminate foodstuffs, damage structural timbers, chew through fabrics or infest stored dry goods. Some inflict great economic loss, others carry diseases or cause fire hazards, and some are just a nuisance. Control of these pests has been attempted by improving sanit…
