Studies on morphology of the life statges and larval behaviour of fruit piercing moth of Othreis fullonia (Clerk) (Lepidoptera: Noctuidae) on Punica granatum


Shendge ES, Chavan RJ

The fruit piercing moths of genus Othreis are very harmful for various fruit crops such as pomegranate, citrus, guava, papaya, mango, sapota etc. The studies on life stages of these pest will help to investigate the delicate and vulnerable stages of life cycle to suggest their management pracices. The present study on the morphology of life stages of Othreis fullonia (Clerk) from egg to adult death and larval behaviour was carried out in the laboratory at room temperature. The egg, pupa stages are non-feeding, the larvae of O. fullonia feeds on leaves of Tinospora cordifolia (Guduchi or Giloy) where as adult feeds on ripening fruits of various above said fruit crops. The complete life cycle of O. fullonia from eggs to deaths is of 45-60 days with an average of 53.15 ± 4.36 days in the case of males and 47- 62days with averages of 55.30 ± 4.31 days in the female. Eggs hatching start at night and early morning and hatching completes in 3.42 days. The eggs measure about 0.98 to 1.005 mm in diameter. Total larval duration in days from first, second, third, fourth, and fifth instar 2.07 ± 0.16, 1.87 ± 0.04, 3.06 ± 0.02, 3.11 ± 0.02, 4.79 ± 0.05 in days and total larval period was 13.5 to 17 days respectively. The length, width of larvae and width of head capsule of first, second, third, fourth, and fifth instar larvae was 4.33 ±0.29, 0.72 ±0.07 and 0.44 ±0.07, 11.75 ±0.22, 1.2 ±0.10 and 0.76 ±0.09, 21.53 ±0.41, 2.15 ±0.16 and 1.34 ±0.10, 32.76 ±1.11, 3.97 ±0.16 and 2.05 ±0.08, 52.19 ±0.46, 8.05 ±0.11 and 4.05 ±0.15 respectively. The Pupae were reddish and blackish in colour and the total pupation period was of 13.11 ±0.81 days and the total adult duration in male and female was 23.05 ±1.25 and 24.83 ±0.91days respectively. The adult of O. fullonia was in colour and of medium size. The male was smaller than the female.The colour of the moth was orange, reddish-brown and greyish-brown in colour. This is the first study of this type from Marathwada, which help to trace the vulnerable and delicate stage of the life stages of O. fullonia.
