Lepisma saccharina

Ctenolepisma Longicaudata

The aim of this research is to investigate the habits and physical and chemical control to control measures gray silverfish (Ctenolepisma longicaudata). Prevention pilot project included the hypoxia method, gamma-ray irradiation and freezing, to exploit for the adults and eggs of the mortality rate and activity performance. Results have shown that, the feeding experiment with different paper material presents gray silverfish caused the weight, machine made tissue paper loss in the most. Under 22°C ambient temperature to maintain the following are detrimental to the hatching eggs. For physical control, Hypoxic method and the freezing test each area could effectively control gray silverfish and eggs. The results showed that the eggs of hypoxia and low temperature resistant than the adult environment, it is necessary to extend the operating time control processing, 6 days of hypoxia treatment could be effective pest control and the need for cryogenic freezing treatment of 3 days for both eggs and adults control. In the gamma-ray irradiation dose trials, data have shown that at the does of 300Gy is able to make eggs and gray silverfish adults reach 100% mortality rate. In chemical control analytical investigation for silverfish, the highest dead number of the insect has the best killing result. Phellodendri Cortex or Mastix solution soaked paper sample have shown antifedant effect to ward the silverfish adult. In addition, when the concentration at 5% for each treatment, the extracts of Calocedrus formosana caused 100% mortality while the silverfish was treated 12 hr. On repellency that, Calocedrus formosana has the best efficacy and followed by Zanthoxylum ailanthoides; Calocedrus formosana has the highest mortality rate. This study was expected to provide the effective environmental friendly method of pest management.
