Abstract
The objective of this study was to evaluate the efficacy of some plant oils i.e. marjoram , caraway and worm wood against S. oryzae and T. granarium at 30, 20 ±1°C and 65 ± 5 % R.H.
Besides, the efficacy of controlled atmosphere (CA) of various carbon dioxide concentrations (25, 50, 75 %) against of S. oryzae and active as well as diapause larvae of T . granarium at 30, 20 ±1 ° C and 65 ± 5 % R.H. was investigated . Also, the efficacy of CA and plant oils mixture against Sitophilus oryzae and active, diapause larvae of T. granarium at the two mentioned temperatures and relative humidity was studied. Furthermore the efficacy of controlled atmosphere (CA) of various carbon dioxide concentrations (25, 50, 75 %) against of S. oryzae and active and diapausing larvae of T . granarium at 30, 20 ±1 °C and 65 ± 55 ± 5 % R.H. was investigated. Experiments were performed at the laboratory of the plant protection department of the Faculty of Agriculture, Benha University.
1-Effect of tested plant oils against the adult mortality of Sitophilus oryzae and the larvae of Trogoderma granarium at 30 and 20 ±1°C and 65±5% R.H.
Wheat grains were used for Sitphilus oryzae and Trogoderma granarium treated with various concentrations (1.5, 1.0, 0.5, 0. 25, 0.125% (w/w) of different tested oils in the laboratory while in case of T.granarium wheat grains were treated with various oils concentrations 4, 3.5, 3, 2.5,2.0, 1.5 % (w/w) at 30, 20 ± 1 ° C and 65 ± 5 % R.H. each replicate was infested with 30 adults (1-2 week old) of Sitophilus oryzae and 30 active or
diapausing larvae of Trogderma granarium. Mortality values were recorded after 1, 3, 5, 7, 10, 14 and 21 days from treatment. The results revealed the following:-
Sitophilus oryza.
