Disadvantages of Biological Control Biological control agents are expensive to find. The greatest expenditure occurs during the field study and the early testing stage, which must be carried out abroad. There may not even be suitable agents. Potential agents are also costly to test for specificity.
Biological control can be less or more expensive than pesticides. You can incur significant expenses studying, choosing, testing and breeding a bioagent. However, in cases where bioagents are applied to low-level pest populations, pest control can be long-term and economical. Some fungi attack insects and kill them.
A fungal spore penetrates the insect and grows all over it. It takes about a week for the insect to die. Fungi are cost-effective, unless a high application rate is needed for severe insect infestations. A major disadvantage of biological pest control may be that it takes a long time to actually control the pest population.
The advantages of biological control, ecology and applications are many. Biological control agents are environmentally friendly and have no side effects for humans. These methods are also comparatively cheaper than other agrochemicals, such as pesticides and insecticides. These methods are also easy to use, available and can be used in any season of the year.
The most important use of biocontrol agents is perhaps that they help reduce the use of chemicals and pesticides that have harmful effects on humans. There are also other disadvantages to using biocontrol methods. The use of biocontrol agents causes a significant and noticeable deterioration in the quality of the products. Biocontrol agents do not eradicate all pests and are a useful and economical tool for pest control only when used on a large scale.
While the chemical process of getting rid of pests has proven successful, success stories in controlling the pest population through a biological process are very few. Insect and other arthropod predators are most commonly used in biological control because they feed on a smaller range of prey species, and because arthropod predators, with their shorter life cycles, can fluctuate in population density in response to changes in prey density. When it comes to the biological method of pest control, the predator used to control pests will control and target only and specifically the pest population. This biological control agent relies on rain at the appropriate times during the season to be successful.
The costs of using biological control are now much lower in Europe than using chemical control for insect pests. The dead host is used by the larvae as a food source, since it is one of the most prevalent methods of biological control. These two approaches are fundamentally different from all other approaches to biological control because they are not intended to establish a population of natural enemies that multiplies to a level where it achieves long-term balance with the population of its hosts or prey. There have also been cases where the biological control agent, when introduced and not native, ultimately becomes a pest.
The ladybug acts as one of the biological control agents, which is safe for both the environment and soil and water. Therefore, accurate identification of the host and parasitoid species is of vital importance in the use of parasitoids for biological control. Nematodes and nuts are most commonly used in biological flood control and prevent the implementation of invasive plants. In classic Biocontrol, an eternal relationship is formed between plants and biological control animals.
Seasonal inoculative release of parasitoids and insect predators has been a highly successful strategy for biological control in greenhouses in Europe. However, if the target plant is useful in certain situations but becomes a pest when left uncontrolled, a conflict of interest arises with respect to biological control. Less persistent pesticides reduce contact, especially if used with knowledge of the biology of the natural enemy to avoid susceptible life stages. .
