Abstract

Adalia and Oenopia conglobata are two polymorphic species of ladybeetles. They are active in all of ecosystems and play important role in control of Aphids. To study the polymorphism of these species, weekly sampling was done in spring and summer in 1400 in Sarakhs region. The specimens were transferred to the laboratory and both species were identified based on their appearance, male reproductive organs and with the help of valid keys. Then, morphs of Adalia and O. conglobata were separated, identified and frequencies of each morph were determined on host plants and host insect too. A total of eight casts were collected for the Adalia ladybug and five casts were collected for the O. conglobata. The highest frequency related to forms five and six for A. bipunctata and forms three and four for O. conglobata. This study was conducted for the first time in the region and can be the introduction of additional research to identify the forms of other species of Coccinellidae family.
