Discuss how an understanding of the biology of insect pests assists in Essay

Discuss how an understanding of the biology of insect pests assists in the control of stored product pests - Essay Example It also helps to determine whether there is an infestation in a given building, what methods should be used to remove it, and provides wider methods for the creation of new pesticides and insect repellents. Reason For Entry, Method of Entry, and Location The primary reason that an understanding of the biology of an insect pests helps in exterminating the pests by giving an understanding as to why the insects would come inside that building at that particular location. Generally, these reasons include coming into buildings seeking food, water, or shelter from the elements. For example, cockroaches are attracted to moisture around pipes and drains, and so buildings with such sources of moisture are more likely to contain cockroaches than drier buildings. Ants, like cockroaches, are also attracted to leaking pipes or condensation build-up, and will enter buildings or rooms in search of this moisture. Ants are also attracted to food sources such as sugar, especially in cases of general p oor sanitation. Locating those food and moisture sources can help determine why the pests are entering the building. Once the reasons for the pests coming in has been determined, the moisture or food source can be removed. Removing the source of food or water should help reduce the number of pests coming into the building, and therefore reduce the difficulty of eradicating the infestation of that building. Once the pests inside have been eradicated and the reason new pests were entering the building is removed, there should be no future issues with that particular pest in that building unless a new source of food or water is presented (Juneau et al., 2010). Additionally, understanding the biology of the insects can help an exterminator understand how the pests are entering the building of infestation in the first place. Crawling insects generally come in through openings into the building which are accessible from the ground. For example, insects may enter buildings through cracks i n the exterior masonry or other building materials, or other gaps in the exterior of the building. Doors left open especially can attract ground-level crawling insects. Small gaps and openings around water pipes, heating and cooling air vents, and exterior windows and doors, can all provide access to crawling insects. However, it is not only ground-level access that will allow in crawling pests that should be looked out for. Exterior landscaping features such as climbing vines, bushes and shrubbery, or tall grasses, may all provide access for crawling insects to reach open windows or other access points that are higher off the ground and would not normally be accessible to such pests (Juneau et al., 2010). Flying pests could obviously access higher points such as open windows that are lacking screens or that have damaged screens with holes that could allow in insects. Looking for such points of access could help determine where the pests are entering the building; blocking these ent ry points would therefore help stop the pests from infesting the building. Understanding the methods the insects are using to enter the building will help determine where the blockades should be placed in order to stop them. Knowledge of the biology of the pests can also help determine what locations in the buildings may be hiding those pests, and therefore where to look to eradicate them. For example, the bodies of bed bugs are almost completely flat. This allows them to hide in
