The biodiversity of lakes is continuously declining and diverse communities are being substituted by monoculture of invasive Eichhornia crassipes, resulting in a slew of environmental cascade effects. The ability of the Neochetina bruchi to self-perpetuate is a desirable aspect of biological control since it decreases the population to a reasonable level, making the approach more sustainable. N. bruchi is often referred to as “ecological engineers” because of the number of services it provides to the environment and enables herbicide application to be substantially reduced. Despite the presence of highly effective weevils against this weed, its effect on water hyacinth in association with the nutrients present in sites, is likely to vary with levels of disturbance caused by natural and anthropogenic factors. Understanding the aspects that determine the performance of these eco-engineers as valuable management tools will help to guide future endeavors. Our objective is to better comprehend their utility and limitations, along with critical knowledge gaps, to further enhance future applications.
