Abstract
A research study was conducted for investigating the biology, infestation level and chemical control of pomegranate fruit borer under field and lab conditions at ARI, Mingora Swat during summer, 2018. The experiment comprised of twenty four trees of Kandahari anar selected from the orchard and eight different treatments were assigned in Randomized Complete Block (RCB) Design having three replications. Treatments including cypermethrin @ 3ml/lit, indoxacarb @ 0.5 ml/lit, bifenthrin @ 2.5 ml/lit, lamda‐cyhalothrin @ 1.5‐2 ml/lit, Azadirachta indica @ 5%, Persicaria hydropiper @ 5%, Eucalyptus globulus @ 5% and control (tap water) were applied four times during the entire experiment at 10 days interval. Influence of different synthetic chemicals and botanical extracts on mean infestation of V. isocrates revealed that lamda‐cyhalothrin resulted in lowest mean infestation (3.740.36) followed by bifenthrin (3.950.32), indoaxarb (4.350.28) and cypermethrin (4.550.28). Botanical extracts i.e., Azadirachta indica (8.000.50), Persicaria hydropiper (7.56 0.27) and Eucalyptus globulus (7.040.70) also performed better than control and reduce the mean infestation of V. Isocrates as compared to maximum yield (16.000.49 ha‐1) was obtained from lamda‐cyhalothrin treated plots while minimum (7.170.43 ha‐1) was recorded in control. Developmental period of V. Isocrates completed in 34‐55 days. Eggs period lasted for 7‐10 days with average of 8.84, larval period for 18‐46 with an average of 32.22 and pupal period for 8‐32 days with an average of 17.60 days. Adult longevity ranges 6‐8 days with average of 6.58 days to complete. Highest 100% mortality was caused by lamda‐cyhalothrin and cypermethrin after 72 hrs followed by neem seed extract (81.00) and Persicaria hydropiper (78.80) when tested under laboratory conditions. Based on the current studies, further studies on the side effect of these botanical extracts are recommended.
