  Codling moth (Cydia pomonella, Lepidoptera: Tortricidae) was monitored and controlled in the valley of Quetta, Balochistan, Pakistan, in an apple orchard by pheromone traps. The moth got climax at 19.50 and 18.85 during Ist and 29.30 and 27.90°C during 2nd generation, 1998, 99 respectively. A total average of 267 and 273 moths were captured during the entire seasons in the said years respectively. Comparing to the chemical control, the results are not attractive, but the study reveals that the technique could be used, for monitoring/forecasting, in addition to the control of the said pest in the field.

  The article provides a bibliographic review of investigation about Cydia pomonella L. (Lepidoptera: Tortricidae); control, through the entire world. It contains different aspects; biology, morphology and different control strategies of the moth in apple, Pyrus malus Linn. (Rosaceae: Pomoidea) orchards. It is revealed that the moth is getting resistance to the pesticides thus other control measures like microbial insecticides, Bacillus thuringiensis, granulosis virus, biological agent, pheromone, mating disruptant, and selected/alternative use of pesticides are recommended.

  The study was conducted to evaluate the appropriate sowing time of newly evolved wheat varieties/cultivars under Bahawalpur conditions. The study included six sowing dates started from Ist November up to 15th January of year 1997-98 to 1998-99 with equal intervals of fifteen days and seven varieties/cultivars viz; Punjab 96, 95-IB-4173, 7061, MH.97, 92128, 92145 with Inqlab–91 as standard one. Regardless of the varieties /cultivars the best results were obtained when wheat was sown after 15th and before 30th November of year 1997 to 1998. However wheat varieties/cultivars Inqlab-91 and V. 7061 gave significantly higher weights in a wide range of sowing period i.e; 15th November to 15th December. The highest mean grain yield of 4255 kg ha-1 was obtained when crop was sown on 15th November (D2) followed by 4212.84 kg ha-1 for sowing on 30th November (D3).

  Pheromone traps against American Bollworm (Helicoverpa armigera, Lepidoptera: Noctuidae) were installed at 01 m from the ground in tomato (Lycopersicun esculentum, Solanaceae). First moth, in the field was appeared during 04th and 03rd weeks of transplantations each year (1995-96) respectively. Maximum mean number of moths (11 and 09) were captured during 11th and 08th weeks of transplantations, when the average temperatures were 28.38 and 26.30°C, each year respectively. A total mean number of 63 and 45 moths were captured during the two years of study respectively. The adult pest remained in the field till the crop was uprooted. The study strongly recommends the use of pheromones than pesticides against the said pest in tomato.

  Pheromone traps against American Bollworm (Helicoverpa armigera, Lepidoptera: Noctuidae) were installed at 1.5 m from the ground in okra (Abelmoschus esculentus L.). First moth, in the field, was appeared during 7th and 6th weeks of traps installation each year 1995 and 1996, respectively. Maximum mean numbers of moths (11th and 7th) were captured during 9th and 7th weeks of traps installation, when the average temperatures were 28.38 and 25.78oC each year, respectively. A total mean number of 24 and 17 moths were captured during the two years of study respectively. The adult pest remained in the field till 11th and 4th August 1995 and 1996, respectively. The study strongly recommends the use of pheromones over pesticides against the said pest in okra.

  Pheromone traps of codling moth (Cydia pomonella L., Lepidoptera: Tortricidae) were installed at different heights (2, 4, 6 and 8 m from the ground) in apple (Pyrus malus Linn., Rosaceae: Pomoidea) canopy in a private farmer orchard, Quetta, Balochistan, Pakistan. Maximum capture was through the traps, hanged at 4 m from the ground. The study reveals that pheromone traps could use for the control of codling moth if installed at suggested height.

  To evaluate the effectiveness of the localized irrigation systems (Trickle and Bubbler) in the deciduous fruits, a survey was conducted in five deciduous fruit trees producing districts; Quetta, Pishin, Loralai, Ziarat and Khuzdar of Balochistan, Pakistan. During the survey 125 farmers were interviewed to get the data about the study. It was observed that only establish farmers having their own farms responded to the localized irrigation systems. Among the localized irrigation systems trickle irrigation was found the best and most practicable system among the farmers.

  A field experiment was conducted to evaluate the comparative effect of Zn levels applied by different methods i.e. nursery root dipping in 1.0% ZnSO4, 0.20% ZnSO4 solution spray after transplanting and 10 kg Zn ha-1 by field broad cast method. A significant increase in Zn content of rice leaf before and after flowering and a significant decrease in P content of straw and paddy and starch content of paddy was recorded for all the methods. N, K and Zn of paddy and straw and Zn contents of roots increased significantly with the application of zinc irrespective of the methods over control. Soil application of Zn was rated superior because it gave significantly higher content of N in rice paddy.

  Pheromone traps against American Bollworm (Helicoverpa armigera Hub., Lepidoptera: Noctuidae) were installed at 1.5 m from the ground in peas (Pisum sativum var. Green Feast). First month was appeared on 25th and 23th April 1994-95 and 1995-96 seasons respectively. Four peaks of the pest infestation were observed each years. 1st peak (13 and 16 months) was recorded on 09-05-95 and 12-05-96 respectively. The average temperatures were 25.50 and 20.45°C, each day respectively. Last peak (16 and 11 months) was recorded on 26-06-95 and 21-06-96 respectively. The average temperature were 25.40 and 24.30°C, each day respectively. A total mean of 424 and 416 months were captured during the two seasons of the study respectively. The adult pest remained in the field till the end of the crop. The study strongly recommends the use of the pheromones than pesticides against the said pest in peas not only to control but also for the monitoring of H. armigea.
