Abstract:
Studies on seasonal Occrrence of fruit piercing moths was conducted at Agricultural College and Research Institute, Madurai. The Menispermaceae plants grown in and around College orchard of Madurai campus were surveyed regularly for the collection of eggs and larvae of fruit piercing moths. Similarly, regular visits were made to guava orchards during the night hours to observe the moth activity. The results revealed that, the rainfall had significant positive association with egg (=0.725), larva (=0.703) and adult (=0.655) population of Eudocima materna. Similarly, relative humidity (=0.350) also exhibited significant positive association with adult population. The egg, larval and adult populations of E. fullonia and E. homaena showed significant positive association with the rainfall and the maximum temperature and minimum relative humidity exhibited significant negative association.
