Pomegranate Fruit Borer (Deudorix Isocrates)
Pomegranate is cultivated in the states of Maharashtra, Gujarat, Madhya Pradesh, Rajasthan, Chhattisgarh, Himachal Pradesh, Odisha, Andhra Pradesh and Karnataka. Among these states, Maharashtra is one of the leading producers of pomegranate. This crop is grown on an average of 109.2 thousand hectares in India. In fruit crops, the majority of insect pests that cause damage are fruit borer, bark eating caterpillar, fruit sucking moth, mealy bugs, and thrips. In addition, occasionally parrots and squirrels may also cause damage to developing fruits. More than 50% of the loss can be reported due to damage caused by fruit borer alone.
Pomegranate fruit borer is also referred to as Anar butterfly. Butterflies lay eggs on a calyx of fruits or buds or small fruits. Emerging larvae make a hole in the fruit and get inside to feed on emerging arils. Fungus and bacteria enter the fruit through a hole made by the larva, and rottenness occurs. The unpleasant odour is emitted from the infested fruit. The drop in fruit and decline in fruit quality can have a serious impact on production. In addition to pomegranate, this insect causes damage to Aonla (Indian gooseberry), Litchi, Peach, pear, Ber, Guava and Sapota.
Integrated Management (IPM):
• On new plantation, prefer less susceptible varieties such as, Dholka, Kashmiri local, Bedana, etc.
• Keep the orchard clean by removing the weed host plants.
• One light trap should be install in orchard.
• Collect the infested fruits having hole and destroy it.
• Collect and destroy the fallen fruits periodically.
• The amount of damage can be reduced by placing a paper or butter paper cone-shaped cap or paper bags over the 30-50 day’s when the fruit attains the lemon size.
• The egg parasitoid Trichogramma sp should be released 2–3 time @ 1 lakh per acre. The eggs of this pest are parasitized by them.
• On initiation, spray need based neem seed kernel powder @ 500 g (5%) per acre or ready to use neem based pesticides @ 10 ml (1% EC) to 40 ml (0.15% EC) per 10 lit of water.
• Spray Bacillus thuringiensis, a bacterial based powder @ 15 g per 10 lit of water.
• On increasing the infestation, spray recommended insecticide after over the picking of matured fruits.
