In single‐ and dual‐tube olfactometers, adult bugs were observed to approach and stretch their proboscis toward the odor source. Every year farmers spend $300 million on insecticides, of which 80% applied for control of chewing insects (Rao, 2007). chemical control, frequency trembler grid lamps and pheromone traps, the methods based on plant attractiveness and repellency, transgenic plant, and biological control, was studied to reduce the population of S. litura. litura causes 35 to 55% yield losses at the flowering and vegetative stages of the crop (Asi et al. Tuan SJ(1), Yeh CC(1), Atlihan R(2), Chi H(3). The future of this study was to prepare a natural pesticide which will not harm the environment and yet control pests. Behavioral responses of the predatory stink bug Eocanthecona furcellata (Wolff) (Heteroptera: Pentatomidae) towards Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) larvae were observed in olfactometers. The effect of several control approaches, i.e. There are several methods such as physical, mechanical, cultural, biological, and chemical methods to control these eco-nomically important pests.
