Carpophilus hemipterus (L.) Pupasının Düşük Oksijenli Yüksek Karbondioksit Uygulamasına Duyarlılığı Üzerinde Yaşın ve Uygulama Süresinin Etkisi

Modified/controlled atmosphere applications, as an alternative to the chemical treatments, are effective technique in controlling pest of stored products, especially dried fruits. In gas tight units, it is applied with principle preventing insect respiration by changing oxygen (O2), carbon dioxide (CO2) and nitrogen (N2) levels atmosphere. study, 1-, 2- 3- d-old pupae fruit beetle, Carpophilus hemipterus (L.), which important pest, were exposed modified / controlled The modified/controlled consisting 2.1% O2 + 90% CO2 7.9% N2 mixture was for 48, 72, 96 120 h at 20°C 75 ± 5% relative humidity. One, two three d old responded similarly application. Mortality rates remained close each exposure time no significant difference found between age groups. Unlike factor, be statistically mortality increased group. highest 38, 60 47% 3-d after application, respectively.
