An experiment was conducted at Post Harvest Technology Centre, Bapatla to study the survival of lesser grain borer, Rhyzopertha dominica in various controlled atmospheres. Initially, the permeability of different packing materials viz. Aluminium Pouch (AP), Poly Ethylene Glycol (PEG), Low Density Poly Ethylene (LDPE) and Plastic Containers (PC) was tested with different levels of O2 (6, 10, 14 and 18%) to find out the suitable packing material for controlled atmospheric storage by using PBI Dansensor. Highest permeability of O2 was recorded in PC, followed by LDPE, AP and PEG over a period of 60 h at all the four O2 levels tested. Later, progeny build up of R. dominica in paddy was tested at various O2 levels (6, 10, 14 and 18%) in all the packing materials for a period of 180 Days. In PEG, no progeny emergence was recorded at all levels of O2 tested, whereas in AP, progeny was recorded at 14% and 18% O2 levels only and no progeny was recorded at 10% and 6 % O2 tested. In LDPE, progeny emergence was recorded in all 4 levels of O2 tested.
