Pheromone impregnated rubber septa is used in the trap which is replaced at fortnightly interval for continuous trapping.Įxample: Heli Lure, use 4 - 5 traps/ ha for monitoring of Helicoverpa.īoth types of traps can be used either monitoring the pest population, predicting the injury level followed by spraying of insecticide including botanicals, microbial and chemical or directly killing the pest. These are species specific attracts and the male moth only. Usually sex pheromones are used for trapping the adult insects. Light trap can be used successfully for trapping them as well as killing with insecticide such as malathion, endoslfan or calcium cyanide.Įxample: Ultra Violet Light trap, Florescent Light Trap Pheromone trap: Gram pod borer and cutworm both belong to the family Noctuidae and are photopositive. Several crawling larvae may fall in these pits and eat the weaker ones so reduce the population themselves. Make cylindrical pits of 6 inch deep at several places in the field. Pit Fall Method:Ĭaterpillars of both pod borer and cut worm are cannibalistic in habit. Caterpillars prefer these coiled grasses as hiding place. Keep the coil of dry grasses at several places in the field at evening hours of the day. Trapping with Coiled Dry Grasses:Ĭaterpillars of cutworm are nocturnal in habit and hide themself inside the cracks and debris in the field. These methods are very effective but labor extensive. Pod borer caterpillars of 3rd instar and onwards can easily be picked-up from foliage and developing pods and killed by hitting with blocks or putting them into insecticide mixed water solution.
Light traps and pheromone trap can be used effectively to monitor the presence of pest as well as to reduce the carryover of next generation, consequently, reduction in pest population. Under mechanical control of chickpea pests, especially the pod borer, Helicoverpa armigera and cutworm, Agrotis ypsilon, larvae can be managed by manual hand picking, trapping with coiled dry grasses and pit fall method, whereas, adult moths can be trapped with various traps.
