Abstract
This study aimed to investigate, for the first time in Egypt, the efficacy of ECO2-Fume fumigant gas (2% PH3 + 98% CO2 w/w) at five concentrations ( 300,400,500,600 and 700 ppm) against immature stages of E. cautella (Hubm), (Eggs, Larvae and pupae) at 28 ± 1 C0 and 60 ± 5 % RH at el Kharga Oasis , New Valley Governorate, 10/4/2011. The results indicated that, egg hatchability and mortality of larvae and pupae were clearly affected with gas concentrations. The same results were found in percent reduction in F1-Progeny. The convenient doseof ECO2 – Fume gas against all developmental stages of E.cautella was 500 ppm (36 g/m3) for 3 days exposure. The results also indicated clearly that, percent infestation in tamr El- Wady increased in date without capsul by this pest. And the effect of gas 100 % mortalities on the pest in date with and without capsul.
