EFFICACY OF DIFFERENT INSECTICIDES AGAINST CYDIA POMONELLA INFESTATION FROM APPLE ORCHARDS IN GILGIT-BALTISTAN, PAKISTAN

Abstract

Codling moth (Cydia pomonella Linn.) is a serious pest of apple and other stone fruits and causes serious economic damage. Present study was conducted to evaluate the efficacy of different insecticides against C. pomonella infestation in Gilgit-Baltistan. In case of cypermethrin, maximum infestation (7.3, 6.3 and 6) was recorded after ten days of first, second and third spray. After this, infestation started decreasing to reach to the minimum (2.3, 1.6 and 1.3) after 30 days of first, second and third spray. Lambda showed the minimum infestation (3.3, 2.6 and 1.6) after 30 days of first, second and third spray. In case of neem seed oil, maximum infestation (8.0, 7.0 and 6.3) was estimated after 10 days of first, second and third spray. Minimum infestation (3.0, 2.6 and 2.3) was recorded after 30 days of first, second and third spray. Before spray, maximum fruit infestation rate was observed and it started decreasing after first spray and minimum infestation was recorded after the third spray and same trend was seen in case of days. This trend was observed with all insecticides i.e. cypermethrin, lambda and neem seed oil. Infestation was recorded as decreasing with the passage of time and maximum was after ten days while minimum was recorded after 30 days with all treatments. There was significant difference of fruit infestation among the first, second and third spray and among the results after 10, 20 and 30 days of sprays. Present results showed that before spray all fields had maximum fruit infestation caused by codling moth and infestation rate decreased after the treatments. It is concluded that cypermthrin is the most favorable insecticides for local apple former of this region to control codling moth infestation.
