What is suppression of a pest?

What is suppression of a pest?

A. Prevention is keeping a pest from becoming a problem; suppression is reducing pest numbers or damage to an acceptable level; eradication is destroying an entire pest population.

What are the 3 types of biological control?

There are three general approaches to biological control; importation, augmentation and conservation of natural enemies. Each of these techniques can be used either alone or in combination in a biological control program.

What do you mean by biocontrol?

Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors.

How does sterile insect technique work?

The sterile insect technique is an environmentally-friendly insect pest control method involving the mass-rearing and sterilization, using radiation, of a target pest, followed by the systematic area-wide release of the sterile males by air over defined areas, where they mate with wild females resulting in no offspring …

Why sampling before and after an insect pest suppression is important?

Assessment of pest density usually requires obtaining actual counts of the pests, and therefore, sampling is important. Because sampling is time consuming and expensive, one must know how to gather enough information about pest abundance to be able to make correct decisions without incurring excessive costs.

What is the purpose of insect control?

Pest control is necessary because rodents and insects carry diseases, infest your kitchens and bedrooms, and bite you or your pets. The purpose of removing any kind of pest from your home, garage, or yard is to keep you safe and healthy. For example, rodents can leave feces on or near food they find in your kitchen.

What is biological control of insect pests?

biological control, the use of living organisms to control pests. A natural enemy such as a parasite, predator, or disease organism is introduced into the environment of a pest or, if already present, is encouraged to multiply and become more effective in reducing the number of pest organisms.

What is the biological method of controlling insects?

Biological control is the use of living organisms to maintain pest populations below damaging levels. Natural enemies of arthropods fall into three major categories: predators, parasitoids, and pathogens (Altieri et al., 2005; Mahr et al., 2008).

Which of the following insect is medical pest?

These include: Diptera (mosquitoes, black flies, horse flies, deer flies, stable flies, sand flies, and various biting midges) Hemiptera, (bed bugs, assassin bugs, water bugs) Thysanoptera (thrips)

What is one disadvantage of sterile insect technique?

The Downsides to SIT One issue is that, for some pests there is no cheap, fast, or effective way to sort through the pests in a large number, and determine whether they are male or female. Another issue is that the amount of radiation used to sterilize the insects, is too damaging to the insects will just die.

What insect pest should be eradicated by SIT?

Using Irradiated Mosquitoes for Mosquito Control. One type of Sterile Insect Technique (SIT) uses radiation to sterilize insect pests. This technique has been used since the 1950s to control insect pests, including fruit flies and the screwworm fly.

What is insect sampling?

Insect sampling is also sometimes referred to as scouting or monitoring. Thus, the main objectives of insect sampling (pest and beneficial) are to: Detect species that are present. Determine their population density.

How are sterile insects being used in integrated pest management?

The four strategic options in which sterile insects are being deployed as a component of area-wide integrated pest management are: suppression, eradication, containment and prevention. For over five decades the SIT has been a major subject of the Joint FAO/IAEA Programme on Nuclear Techniques in Food and Agriculture.

What is species-specific insect control (sit)?

The SIT differs from classical biological control, which involves the introduction of non-native biological control agents, in several ways: Sterile insects are not self-replicating and therefore cannot become established in the environment. Breaking the pest’s reproductive cycle, also called autocidal control, is by definition species-specific.

How effective is this bug repellent for bites?

Containing 34 percent DEET, a common bug repellent that’s recommend by the CDC and EPA, this bug repellent isn’t messing around when it comes to safeguarding your skin from insect bites. If you don’t mind the strong smell, you’ll be lower your risk of bites from mosquitoes, biting flies, chiggers, ticks, fleas, and gnats for as long as 12 hours.

How do insects disguise themselves to avoid predators?

Warning colors used by unsavory insects work so well, perfectly tasty and non-toxic insects have taken to disguising themselves as insects that predators know to avoid. The most classic example of this mimicry, a defensive adaptation described by Henry Bates, is the viceroy butterfly.
