Název v původním jazyce

Rapid assessment of the sex of codling moth Cydia pomonella (Linnaeus) (Lepidoptera: Tortricidae) eggs and larvae

Popis výsledku v původním jazyce

Two different methods were tested to identify the sex of the early developmental stages of the codling moth with a WZ/ZZ (female/male) sex chromosome system. First, it was shown that the sex of larvae can be easily determined by the presence or absence of sex chromatin, which is formed by the W chromosome in interphase nuclei of females. Secondly, a new sexing technique was developed based on the molecular marker CpW2-EcoRI of the W chromosome. For this technique, a fragment of a codling moth gene, period (Cpper), was isolated and sequenced. Results of southern hybridization suggested that the Cpper gene is located on the Z chromosome. Then a multiplex PCR assay was developed, which co-amplified the CpW2-EcoRI sequence to identify the W chromosome andthe Z-linked Cpper sequence, which served as a positive control of accurate processing of tested samples. The multiplex PCR provides an easy and rapid identification of the sex of embryos and early larval instars of the codling moth.
