The ber moth, Thiacidas postica walker (Lep. Noctuidae), dispersal and natural enemies in Bushehr province

The ber moth (Christʹs thorn moth) is one of the most important pests of defoliator in Bushehr province. In this project the ber moth were collected over ber forests to identify and confirm their species in noctuidae family using male genitalia. The femaleʹs abdomen was cut after detecting them from males and was placed in cold KOH (10% solution) at 24-48 hours. Then it was transferred to distilled water and genitalia was come out in a precise process. Aedeagus was come out of male reproduction system and vesica was everted by a tiny syringe. The genitalia colorated then dehydrated in different degree of alcohols. At last elements were fixed in xylene and clove oil. The results showed Thiacidas postica walker (Lep: Noctuidae) is the most important pest (ber defoliators) in Bushehr. The tegumen of the male genital was large, strongly sclerotized and roof-like. The vinculum was U - shape and without saccus. Uncus was simple, interlay it covers by hairs, without corona and male genitalia has symmetric shape. proboscis lacking, palps with three small segments and the third segment is the smallest, antenna is pectinate, head and thorax full covered by scales especially on the notum. Apex of front wings with<90 c angle. External margin of wing (Termen) is swelling. Females with 16-20 mm length and wingspan is 40-44 mm. Males with 12-15 mm length and wingspan is 32-35mm. Head, thorax and front wings are grey - brown with black swell strips. Frontal wings with two pairs zigzags strips. Adults are preovigenic. T. postica walker often fined in low - heights paces and beaches, feeding on different per species (Ziziphus spp.) There tachinid species with names Pales murina Mesn., Compsilura concinata Mg. and Drino nr. imberbis. Wied. were separated of larvae in the field. These species showed high efficiency and parasitism rate about 30%-70%.
