Why is A Fungus Used As A Biocontrol Agent?Īnswer: Fungal biocontrol agents do not harm the environment and have proven themselves to be a cheap alternative to harmful chemical pesticides, and they also do not need to be ingested by the host but can invade them directly. The biocontrol agents do not eradicate all the pests and are a useful and economical tool for pest control only when used on a large scale.ġ. The use of biocontrol agents causes a significant and noticeable deterioration in the quality of produce. There are several other demerits of the use of biocontrol methods too. The most crucial use of biocontrol agents is perhaps they help in reducing the use of chemicals and pesticides which have harmful effects for human beings. These methods are also easy to use, readily available and can be used in any season throughout the year. These methods are also comparatively cheaper than other Agrochemicals like pesticides and insecticides. The biological control agents are environmentally friendly and do not have any side effects for humans. The advantages of biological control ecology and applications are plenty. The dead host is then used by the larvae as a food source as is one of the most prevalent methods of biological control.Īdvantages and Disadvantages Of Biological Control

The parasitoids lay eggs in the body of their hosts which ultimately leads to the death of the host. These viruses would be specific regarding their hosts and would hence be effective biocontrol agents. The creation of a virus which would selectively target pests and act as biological control is still under scientific research. Bacteria form a biological method of pest control. The bacteria infect insect's digestive tracts which limit the options for insects which have sucking mouthparts. The bacteria which belongs to the genus coccobacillus are more comparatively more pathogenic to insects and hence used for biological control. Considering insects majorly consumed crops, the ideal predators to act as a biological method of pest control are spiders, dragonflies, lacewings, etc. Predators are mainly free-living organisms which consume other animals in a large number of prey in the span of their lives. Entomophaga is a form of fungi which is effective against green peach aphid that forms a biological method of pest control. Fungi as a biocontrol method are gaining widespread popularity in recent times. Fungi as a biocontrol method have proved to be a very effective alternative to chemical pesticides. Fungi as a biocontrol method are considered a rapidly developing method and do not cause any harm to the environment. In the classical Biocontrol, an eternal relationship is formed between plants and biological control animals.īiological control agents' examples are given below: Fungiįungus, as a biocontrol method, forms a biological method of pest control. This method of Biocontrol makes use of the natural prey-predator relationship. Classical Biocontrol is another process which helps in the organic method of pest control. Nematodes and nuts are most commonly used in inundative biological control and prevent invasive plants from implementation. This approach makes use of pathogens that help to control the growth of weeds and is as effective as herbicides. inundative Biocontrol makes uses of pathogens. Natural biological control can be done using two primary methods. The natural animals in the form of parasitism, predation along with other similar mechanisms perform the role of biocontrol agents which help in maintaining the balance. Weed infestation and pests are controlled with the help of insects, pathogens and grazing animals. The biocontrol methods are a long-term method and most importantly, a self-sustaining one which helps in the control of invasive species of plants.

Use of Biocontrol agents are also called biological control and are mainly used for the reduction of pest population and produce yields which are free of any pests. Biocontrol can be defined as the control of the type of living organisms with the application of another.
