physical control of insect pests

Pests have been controlled using physical and inechanical methods since the origin of agriculture. You will study about these methods in detail in this unit. Objectives After studying this unit,you will be able to: explain various physical methods of pest control and describe the mechanical methods of pest control. 10.2 PHYSICAL CONTROL METHODS

The scope of physical control of insects is summarised and recent developments (post -1969) in the field are reviewed. Physical control though offering great potential as a component of integrated control systems is not yet in widespread use against field pests. In stored commodity protection physical methods are of increasing importance and ...

The general methods to control non chordate stored grain pests (especially insect pest) are much in common. Similar preventive, physical and preservative methods are used for almost all the insects, mites and arachnid pests however; biological method of control may vary in different species. Preventive Measures: 1.

Pest control methods fall into a few categories: Physical pest control, such as traps and barriers. Chemical pest control, such as pesticides and rodenticides. Biological pest control, such as predatory and parasitic insects. Integrated pest management, or IPM, combines elements of all three to holistically manage pests across …

Provides a direct approach to dealing with pests. Many physical measures, such as spikes, are long-term solutions. Physical controls, play an important role in pest-proofing as a preventative control measure. 3. Chemical Pest Control. Chemical pest control refers to the use of pesticides, which are chemicals formulated to kill or …

The three main types of biological pest control methods include: 1. Importation. 2. Augmentation. 3. Conservation. Various agents that eradicate the pests by natural means include; bacteria, fungi, parasitic insects, pathogens, and predators. The combined action of these agents proves beneficial in controlling the pests.

Physical control methods work well with either pesticide-centered, genetic resistance or biological control-centered integrated management strategies. Table 1 …

Biological control is a component of an integrated pest management strategy. It is defined as the reduction of pest populations by natural enemies and typically involves an active human role. Keep in mind that all insect species are also suppressed by naturally occurring organisms and environmental factors, with no human input.

Likewise, insect nets proved as effective physical barriers between the plants and pests to cut off the movement of flying insect pests in the vegetables crops (Vincent et al. 2003; Boiteau and ...

Another way to manage insect pests is to plant a crop that is very attractive to insects and then treat the trap crop with insecticide. ... management options include cultural (physical removal of the bags), biological (using natural predators), and chemical control. Physical removal of the bags is a possibility, but if bags are too high they ...

Consequently, several physical control methods are used in postharvest situations. Two noteworthy examples are the entoleter, an impacting machine used to crush all insect stages in flour, and hot-water immersion of mangoes, used to kill tephritid fruit fly immatures in fruit. The future of physical control methods will be influenced by ...

Physical control measures are very important tools in pest management, but more research on these relatively simple techniques could have vast consequences, similar to the revolution in agriculture created by the exclusion screens. The beauty of physical control measures is that there is no need for the monetary expenditures on the order of ...

Physical strategies of insect pest management encompasses all approaches aimed at restricting pest access to the crop by causing behavioral changes or killing the insect (Vincent et al.,...

It is also important to use pest-free transplants. Some vegetable crop transplants can be infested with insect pests, and growers using these transplants are put at a considerable disadvantage. Physical and Mechanical Control The use of physical barriers such as row covers or trenches prevents insects from reaching the crop.

An electric field is the space surrounding an electric charge, within which it is capable of exerting a perceptible force on another electric charge. Especially under high voltage, electric fields induce various …

Integrated Pest Management (IPM) is the integration of two or more pest control tactics into one program and is considered an environmentally acceptable and economically profitable means of managing insect pests. Physical, mechanical and cultural control methods hold promise from pre- to post-harvest situations of the crop …

The frequent occurrence of forest diseases and insect pests has a significant impact on the forest ecosystem. The government needs to take measures to protect the forest ecosystem. The common management modes for forest pests and diseases include pesticide control, physical control, and biological control. In the …

Abstract: The Special Issue 'Insect physical control: electric field-based pest management approach' was launched to showcase valuable new research on pest control using applied electrostatic engineering. Some phenomena generated in static and dynamic electric fields can be used to build new devices to capture or kill target insects …

Physical control methods aim to prevent or reduce pest invasion into a crop. various physical means function either mechanically or by affecting insects' viability or behavior. For example, insect suction devices, insect glue, and electromagnetic energy suppress insect populations. Insect exclusion screens also reduce insect density, though ...

Physical Barriers for the Control of Insect Pests. Gilles Boiteau & Robert S. Vernon. Chapter. 588 Accesses. 12 Citations. Abstract. Insecticides have become such an …

Physical Control of Insect Pests 795 P Several avenues have been explored for applying the different forms of electromagnetic radiation as a tool for controlling insects.

The scope of physical control of insects is summarised and recent developments in the field are reviewed and in stored commodity protection physical methods are of increasing importance and may completely replace current chemically‐based protectant methods. The scope of physical control of insects is summarised and recent developments …

Dynamic electric fields also have potential for novel physical measures to control insect pests. Two works [25,26] have reported unique apparatuses that cause an arc discharge to hit insects that enter a dynamic electric field. Arc-discharge-generating techniques may provide a new tool for detecting and dismembering insects nesting in …

Everything you need to learn about how to control pests in crops. 5 Ways to Control Pests in Crops:- 1. Cultural Control 2. Physical and Mechanical Control 3. Biological Control 4. Chemical Control 5. Legal Control. Cultural Control: By cultural control, it is meant those methods of planting, growing and harvesting a crop which will […]

Chemical Pest Control Methods – The most well-known way of controlling pests is by using pesticides and rodenticides. Chemical types of pest control have been seen as reliable, and tackle a large portion of the pest population. Pesticides are usually used in certain circumstances where no other method will work.

Physical control methods aim to prevent or reduce pest invasion into a crop. various physical means function either mechanically or by affecting insects' viability or …

Temperature-based methods of pest control involve using heat or cold to kill pests. Each pest has specific temperature thresholds that, when exceeded, can be lethal. List of temperature thresholds for common pests: Bed Bugs: Above 45°C (113°F) for 90 minutes. Weevils: Below -18°C (-0.4°F) for four days. Cockroaches: Above 48°C …

Study with Quizlet and memorize flashcards containing terms like Pest, 4 main groups of pests, 6 general pest management methods and more.

Lower temperatures can kill insect pests. For example, grain kept at -5°C for 12 weeks will control stored insect pests at all life stages. You can lower the temperature of stored grain by: mixing and transferring infested grain from one bin or pile to another. transferring part of the crop to a truck or small pile to expose it to low air ...
