Plant pests and pathogens interfere with the growth and cause damage to cultivated and naturally growing plants. ... As a consequence, it is estimated that pre- and postharvest pests and diseases destroy at least 30–40% of global agricultural production.
What are the effects of pest?
Infected seeds, crops, and vegetables have low market value. Pests reduce the quality of crops. Pests eat up leaves of crops, thereby reducing the photosynthetic activity of the plant. They cause injury which may predisposes crop to diseases attack.
How do pests affect plants?
They have a direct impact on agricultural food production by chewing the leaves of crop plants, sucking out plant juices, boring within the roots, stems or leaves, and spreading plant pathogens.
How do insect pest affect crop production?
Crop Damage
The first is direct injury to plants caused by insects eating leaves and burrowing holes in stems, fruit and/or roots. The second is indirect damage, where the insects themselves do little or no harm, but transmit bacterial, viral or fungal infection to a crop.
Why are pests bad for crops?
pests affect plants. ... Pests also destroy the habitat of other organisms as well as natural resources, leading to reduction in water quality, increase in soil erosion and degradation of land, and destruction of native plants that provide food and shelter to native species or those endemic to the place.
What are pests in agriculture?
Pests can include weeds, plant pathogens (certain fungi, bacteria, and viruses), rodents, 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.
How pest and diseases affect agricultural production?
Transboundary plant pests and diseases affect food crops, causing significant losses to farmers and threatening food security. The spread of transboundary plant pests and diseases has increased dramatically in recent years.
How do pests affect the environment?
Types of pests and diseases
Plants can overrun crops, native forests, waterways and marine environments. Bugs and parasites can attack people, animals or plants, and spread disease. Larger animals can feed on native species and spread disease. They can also severely damage and modify soils, landscapes and seascapes.
How do pests destroy crops?
Insects are responsible for two major kinds of damage to growing crops. First is direct injury done to the plant by the feeding insect, which eats leaves or burrows in stems, fruit, or roots. These swarms may completely destroy crops in an invaded region. ...

Insects with piercing-sucking mouthparts have strong mandibles that they move laterally to often cause yellowing or browning on plants, and possible wilting. Examples include aphids, scales, spider mites, and whiteflies.
What are the major losses caused by pests in agricultural crops?
Results showed that pests and diseases led to high primary yield losses (26%) and even higher secondary yield losses (38%). We identified the fruiting nodes and the dead productive branches as the most important and useful predictors of yields and yield losses.
What are the harmful effects of insects?
ejaculation, overflowing menstruation, epilepsy, malaria, typhoid, chest pain, hypertension, and ulcer. growth of plant roots and plants generally, (Emosairue, 2007). helminthes of humans. Order Hemiptera (Bugs, Bed bugs): These give irritating bites.
What are the effects of economic pests to agricultural crops?
The impacts of reduced productivity on crops or animals can be long-lasting. Pest infestations can impair fertilization rates or seed recovery, while pesticide applications can harm soil and water fertility.
Why are pests problems?
Pest insects can have adverse and damaging impacts on agricultural production and market access, the natural environment, and our lifestyle. Pest insects may cause problems by damaging crops and food production, parasitising livestock, or being a nuisance and health hazard to humans.
Why pests should be killed?
Animal pests and threats have a major detrimental effect on our environment. Controlling them is essential for the survival of our native plants and animals.
Why are pests increasing?
Since temperature is the most important environmental factor affecting insect population dynamics, it is expected that global climate warming could trigger an expansion of their geographic range, increased overwintering survival, increased number of generations, increased risk of invasive insect species and insect- ...
