Title

Determination of Supercooling Point and Some Affecting Factors in Jasmin Moth, Palpita Unionalis (Lep.: Pyralidae)

Pages

  35-43

Abstract

 The olive leaf moth, Palpita unionalis (Hubner) is an important pest of nurseries, young olive orchards and also on the suckers of old trees. Strategies adopted by insects spend the winter in order to exert an important role in the viability of this, one of this strategy is their freezing temperature regulation. In this study, Coldhardiness of this pest and some influencing factors such as photoperiod and host plant on the suppercooling capacity of P. unionalis have been studied. The colonies at temperature 24± 2oC, relative humidity 60± 10% and 8: 16 (dark: light) h photoperiod was maintained. In The first test suppercooling points (SCP) of the overwintering individuals (larvae 5 and pupae) of P. unionalis were grown in three photoperiod, 16, 12 and 8 hour light, and analyzed. Different photoperiods had significant effects on SCP of larvae 5 and pupae (p <0. 001), so short days in pupa stage show more suppercooling capacity. In the second test SCP of the overwintering individuals of the four host plant, olives, jasmine, ash and prim were maintained in 16 hours light were measured. These results suggested significant effects of host plant on the SCP (p <0. 001), so those fed olive plants showed greater cooling capacity. The results obtained in this study indicated that the, P. unionalis is chill-intolerant pest.
