The objectives for this study include to learn the different pesticide used how effective they are toward orange tree pests. The methods to the study include taking 30 samples from 30 different orange trees before and after pesticide spraying. I Collected and recorded the insect abundance and insect composition and facilitated graphs and tables. The results of the study are that pesticide use is very effective but very expensive. Nearly all insects on the on the trees were eliminated after the spraying. The implications of the study are, from talking with scientist Dr. McCoy at the University of Florida Agricultural Center, pesticide use is expensive and only used on oranges that are to be sold for eating because cosmetically they look appealing. However for the most part the grove farmers in central Florida use biological control such as lady bugs, this method is much cheaper but cosmetically less appealing therefore the oranges are processed into juice.
