Are pesticides harmful to beneficial species?
Many of the pesticides used today are broad-spectrum and non-selective, meaning they are just as detrimental to beneficial species as they are to the pests themselves. This is one of the downsides of pesticides and herbicides.
How do pests become resistant to pesticides?
In relation to pesticide use, genetic resistance has occurred in many pests over the years, especially insects. When a pesticide is applied to crops, most of the pests are killed, but it is possible that some individuals survive because they possess the ability to metabolize or detoxify the pesticide.
What are the disadvantages of biopesticides?
The very high specificity of the products might be a disadvantage when a complex of pest species needs to be controlled. Since biopesticides often contain living material, the products have reduced shelf lives. Also, their efficacy is often variable due to the influence of various biotic and abiotic factors.
