Özet

Hypercarbia-induced delay in the development of eggs was investigated in almond moth, Ephestia cautella (Walker, 1863) (Lepidoptera: Pyralidae), using two controlled atmospheres (CAs), 85% CO2 + 3% O-2 (balance N-2) and 95% CO2 + 1% O-2 (balance N-2) between 2012 and 2014 in Stored Products Pests Laboratory, Agricultural Faculty, Ankara University. Eggs of E. cautella (1-3 day-old) were exposed to both CAs for a wide a range of exposure periods of up to 104 hat three temperatures of 20 +/- 1, 25 +/- 1 and 30 +/- 1 degrees C at 65 +/- 5% RH. In general, both CAs caused delay in egg development by 1 to 8 d. Inhibitory effects were more pronounced at lower temperatures. A maximum delay of 8 d was recorded at 20 degrees C for the three-day-old eggs exposed to 95% CO2 plus 1% O-2 for 88 h. Short exposure periods caused short term delays in development. Four h exposure caused 1d delay in three-day-old eggs exposed to 95% CO2 plus 1% O-2 at 25 degrees C. In practice, total egg hatch including delays lasted 5 d at 30 degrees C, 8 d at 25 degrees C, and 12 d at 20 degrees C, which must be taken into account for successful CAs applications.
