| Popis: | PCR is a useful technique to detect mutations in insecticide resistance genes or to analyze gene flow in pest insects. Plutella xylostella (L.) is one of the most important pests that develops insecticide resistance, and it is desirable to make efficient use of specimens obtained from pheromone-baited sticky traps. To estimate the period of DNA preservation in moths collected on traps in the field, we analyzed the probability of PCR success using mtCOI and microsatellite primers. The results suggested that moths caught by sticky traps would maintain DNA of sufficient quality for PCR analysis when the trap was changed weekly. DNA degradation was greater in moth specimens on traps exposed to ultraviolet (UV) radiation in direct sunlight than in the shade. DNA degeneration was greater in moths exposed to direct sunlight in summer than in winter. Therefore, setting traps in shade or using a UV light-shielding barrier over the trap might be an effective approach to prevent DNA degradation. |
