COVERING MATERIALS USE IN THE MANAGEMENT OF GREENHOUSE APHIDS IN VEGETABLE PRODUCTION
Keywords:Covering materials, greenhouse, aphids, and UV-blocking
Vegetables are not only important but necessary components of daily human nutrition attributed to their ability to supply vital nutrients such as vitamins, minerals, dietary fiber, micronutrients, and bioactive compounds. However, greenhouse productions of vegetables are still constantly faced with low yields and quality due to increased aphid incidence and occurrence resulting in huge economic losses accompanied by the rapid spread of viral diseases attributed to aphids as vectors. Therefore, this document focuses on the advanced usage of covering materials in the control and management of aphids during greenhouse vegetable production by reviewing recent research articles on the role of covering material in insect pest management. The use of covering materials such as UV- absorbing, insect-proof nets, long-lasting insecticide-treated nets (LLINs), anti-aphid nets, colored nets (black and white), nanoparticles embedded chemicals and Linear low-density polyethylene (LLDPE) greenhouse covering films covering material significantly reduce aphid incidence and population. This presents an invaluable opportunity for the use of covering materials to manage aphids during the greenhouse production of vegetables. Lack or less ultra-violate (UV) solar radiation inside a greenhouse does interfere with flight activities, dispersal behaviors, mating or feeding behavior, aphids may fail to differentiate the different colours of their host. This disrupts their orientation, effectively reduces their infestation, population and lowers the extra cost involved in their control and management.
