(Futch, 2014). Almost all farmers do Integrated Pest Management (IPM) through normal crop production practices. It is a balanced and tactical approach to pest control. According to the Citrus Industry (2014), there are other forms of pest control like Biological Control uses natural enemies to control and suppress the pest effectively; this is often targeted against pests that are not native to the geographical area. Mechanical Control is the use of devices, traps, machines and other physical methods to control or change the environment where the pest has festered. The devices used to prevent the pest from entering an area or in catching the pest for removal. Cultural Control alters the environment, condition of the host or site to prevent or suppress the infestation of the pest like removing the food, water, shelter or other necessities that are important to the pest’s survival. Physical/ Environmental Modification controls the pests and reduces their population by modifying the environment where the pest is found, like modifying the temperature, humidity and air movement. Chemical Control is the use of pesticide, while it is considered to be effective; it is only effective in selective stages and varies in the length of efficiency. Some may provide pest control for only a short time frame and can be measured in a few hours to days.
