Final answer:
Using the same insecticide repeatedly can lead to insect populations developing resistance due to natural selection. To prevent this, a variety of ecologically based pest control methods should be used, such as biological control tools, to effectively manage insect populations and minimize environmental disruptions.
Step-by-step explanation:
Practices that will likely result in insecticide-resistant insect populations include repetitive use of the same chemical, repetitive use of the same chemical class, using too much product, and using too little product. The development of resistance is a form of microevolution, where through natural selection, the most resistant insects survive and pass on their traits to their offspring. Avoiding resistance can involve using a variety of methods to control pests, such as reducing the use of synthetic chemicals, adding pest-controlling species to the ecosystem, and adopting ecologically based control measures.
Ecologically based practices, such as biological control tools, which introduce species that prey upon and destroy pest species, have been proven to be effective in controlling insect populations and preventing the development of resistance, thus protecting the environment and potentially lowering costs.
