Abstract
This study was conducted at the laboratory of stored
products pests of the Plant Protection Depmtment, Faculty of
/\gricullure al Moshlohor. Tukh, <)ualyuhia, /,:tga:;.ig llniwrsily and supported by the National project of integrated pest management for post-harvest pests financed by EEC-counterpart funds, Ministry of Agriculture and land Reclamation, Egypt.
. The objective of this study was to investigate the effectiveness of certain methyl bromide alternatives i. e. contrqlled atmospheres (CA) of various carbon dioxide concentrations; CA of vety high nitrogen content, phosphine gas produced• from metal phosphide (aluminium or magnesium) and combinations of phosphine and carbon dioxide against some stored product-insects inside gastight bins.
Insects tested were the adults and immature stages of the rice weevil Sitophilus oryzae (L.); lesser grain . borer Rhizoperth.a dominica (F.) and the red flour beetle Tribolium castaneum (Herbst.) as well as active and diapausing larvae of Khapra beetle Trogoderma granarium Evetts.
The chosen treatments as methyl bromide alternatives were tested inside gastight steel bins each of 0.5 m3 volume and was filled with ca. 450 kg wheat grains.
The bins were designed and co:nstructed by the airplane Factory at Helwan and were situated on the roof of the building of the Plant Protection Depmtment of the Faculty of Agriculh1re at Moshtohor, Tukh- Qualyubia- Egypt.
