ABSTRACT
Abstract | The morphological study of Trilocha varians was carried out under laboratory conditions at MNS-University of Agriculture, Multan on Ficus benjamina. All stages from eggs to adult were recorded and observed. The complete metamorphosis like egg, larva, pupa and adult was found in T. varians. The female laid eggs in 2 to 6 layers. The diameter of egg was 0.60 to 0.70mm. There are five larval instars of T. varians. The head length of 1st, 2nd, 3rd, 4th, and 5th instars was 0.30±0.05, 0.35±0.07, 0.93±0.08, 1.67±0.40, 2.09±0.09mm, respectively, while width of 1st to 5th larval instar was 0.28±0.02, 0.38±0.05, 0.89±0.06, 1.56±0.30, 2.00±0.07mm, respectively. The average body length of first, second, third, fourth, and fifth larval instar was 2.05±0.45, 4.01±0.50, 8.60±1.45, 14.17±3.01, and 23.01 ±4.99mm, respectively. A caudal horn is present on the dorsal side of the 8th abdominal part on each eruciform larva. The average length and width of male cocoon was 9.90 ± 1.00 and 4.74 ± 0.52 mm, respectively. The length of wingspan of male and female was 17.44 ± 1.56, 5.66 ± 0.49 mm, respectively, while body length of male and female was 8.84 ± 0.90mm, respectively.
