What are aphids?


Aphids are small insects belonging to the homopteran family. Which are oval in shape and are generally between 3 and 4 millimeters in size. These insects are particularly resistant to the environment and are found on a variety of plants throughout the world.

These insects are usually green or yellow and have short legs and a tail with a variety of hairs. The key to recognizing these insects is their ability to deposit a considerable amount of water suction. A liquid containing large amounts of nutrients and proteins that allows them to survive in the environment. Aphids are mobile creatures, often hopping from one plant to another. These insects are also know as aphids, aphids and plant lice.

Aphids feed on the sap of many plants. Which allows them to reproduce massively and damage and weaken the plant they live on. They are therefore consider pests, although some aphids can benefit plants by reducing terrestrial overgrowth, such as grasses and turf. A variety of natural predators of aphids are present in nature, including insects such as coccinellids, nematodes, spiders and beetles.

They have a short life cycle, which allows them to multiply rapidly

The eggs of these insects are deposit on the lower part of the plant. Then the eggs become larvae and then full adults. Normally, some adults go to the top of the plant to lay eggs again. These insects are resistant to many synthetic pesticides and must be treat with environmentally friendly contact pesticides, which are apply directly to the plants.

Aphids can be a major threat to agriculture, gardening and forestry. Not only do they feed on plant sap, but they also produce a substance called honeydew, which attracts predatory insects. These molasses can also coat the undersides of plant leaves, which can lead to leaf blackening or death of the plant. Therefore, it is important to make an early diagnosis of these insects to treat the infestation before it has a significant effect on crop production.

This can be a major threat to agriculture, gardening and forestry, as these insects can destroy plants if not properly treated.

What problems do aphids cause in agricultural crops?

Aphids are parasitic insects that feed on the sap of many plants, including agricultural crops and gardens. Aphids are know for their tendency to spread rapidly, making them one of the major pests of gardens and orchards worldwide. Most aphids are dark brown or brown. They may also have mottled or bee-tailed color patterns. These insects are very small, averaging between 1 and 3 millimeters. Aphids are commonly found on flowers, leaves and roots of agricultural crops.

The problems generated by aphid on agricultural crops are significant and considerably diverse. The rapid grow of their populations, their ability to spread diseases between plants, and their inability to be easily control make aphid control a topic of great interest. One of the main ways aphids damage agricultural crops is by sucking plant sap. This reduces the amount of nutrients that are absorb by plants from soils, which decreases overall production. The sap sucked by aphids also contains a high concentration of simple sugars, which act as a medium for pathogens to spread to other plants. This contributes to increased disease among plants and uneven damage among affected crops. In addition, aphids excrete a sticky substance, called aphid honeydew, which causes crop diseases.

Another problem caused by aphids on crops is the production of a large amount of chemical defenses, called phytotoxins

These phytotoxins are toxic chemical compounds form from aphid enzymes. These phytotoxins bind to plant sap, which often leads to twisting, changes in the color of the hazae or complete death of the plant. Also these phytotoxins cause leaves to separate from stems, which reduces crop productivity even further.

In addition to direct damage cause by aphids. Other beneficial organisms can have a negative effect on crops if they are affect by aphids. For example, aphids can kill auxiliary insects that help control parasites in fields. This means that parasites begin to have contact with crops without any control, resulting in decreased yields. Aphids can also reduce the number of pollinators visiting fields, which increases production costs in terms of artificial pollination.

It is important to understand the average importance and the great health risk caused by aphids. Aphid control in agricultural crops must be address in a practical way to ensure high food production. A holistic approach to aphid control must be carry out. This in

Preventing crop infection with aphids

Aphids are common insects in agricultural cycles around the world. These small creatures have a bite that allows them to bleed crops and cause yield problems. Preventing crop infection with aphids involves a mixture of biological, chemical and practical methods.

First, it is necessary to limit the number of aphids on the farm. This can be achieve by controlling soil moisture and nutrient levels, and by proper pest control. Biological repellents such as bitter castile, neem and mineral oil are useful in deterring aphids. These substances are apply to the leaves with an atomizer, and form a protective coating against aphid bites.

Chemical pest control products can also be use. These products should be handled with caution, as they can harm human health and the environment. Naturally, proper safety precautions should always be taken before using any chemical.

In terms of pest control practices

One of the best ways to prevent crop infection with aphids is to reduce the number of suitable hosts. That is, by removing weeds and grasses that are potentially susceptible to aphids after each harvest. The use of trap-crops (crops such as barley, oats and lupine) also helps to attract aphid, distracting them from the main crops.

Environmental factors, such as temperature, humidity and adequate sunlight, must be take into account. These three factors are essential to prevent aphid infection of crops. For example, a warm, humid environment with an optimal amount of sunlight is an excellent defense against aphid.

Preventing crop infection with aphid requires a combination of good practices, chemicals and biological controls. To achieve optimum protection, growers must have good crop management practices. Reduce the number of suitable hosts, and control environmental factors. Once a good aphid defense is established, growers can be confident that their crop will be protected.
