The highest population of insects in tomato plants using organic fertilizer was Hemiptera (Family Miridae: Nesidiocoris tenuis) with 115 individuals, and the lowest population was Lepidoptera (Family Pyralidae : Diaphania indica), with 2 individuals. The highest population of insects in tomato plants using non-organic fertilizer was Hemiptera (Family Miridae : Nesidiocoris tenuis), with 125 individuals, and the lowest population was Lepidoptera (Family Hesperiidae : Erhionata thrax), with 1 individual.
