The study was conducted to find out the combined effect of multiple non-pesticidal treatments to test the commercial dispensers of synthetic chemicals as mating disruptants in conjunction with biological control and spray of organic oils, simultaneously. The eggs of Trichogramma planteri were also released in an entire orchard to supplement the other pest management practices. The pheromone traps were fixed with the beginning of the eggs hatching to monitor the population. The results show that the overall effect of non-pesticidal practices were significantly encouraging in decreasing the population of the pests as compared with untreated orchards. The natural enemies alone were not effective in keeping populations below economic levels. Similarly, the organic oils were also mildly effective when applied alone as compared with the phytotoxic spray or applied at higher rates during the hot weather.
