Abstract : Survey and study the population of important stored insect pests on Australian rice (Oryza sativa L.) , Saudi wheat (Triticum aestivum L.)and Barni date (Phoenix dactylifera L .) were carried out in north , middle and southern Jeddah Province in 28 / 6 / 2008. Results obtained summarized as follows: Oryzaephilus surinamensis (L.) is the most important insect pest that was presented on the three hosts . While, Rhyzopertha dominica (F.) and Tenebrio molitor (L.) were recorded only on Australian rice and Saudi wheat. Ephestia cautella Walker. was presented only on Barni date . O. surinamensis was dominant insect on rice and date while , R. dominica was dominant on wheat as compared with the other insects . The highest insect population was found on Barni date and the lowest one on Saudi wheat . The highest level of insect infestation was recorded on Australian rice in southern company stores of Jeddah Province and on Saudi wheat in southern mills but the highest insect infestation was recorded on Barni date in the middle establishment of date followed by southern centers of date and the lowest insect infestation was in north free sellers of Jeddah Province . Furthermore , the laboratory experiments were carried out on Biology Dept. Faculty of Science, King Abdul Aziz University – Jeddah –Kingdom of Saudi Arabia to study the effect of host preferences of O. surinamensis adults and the effect of different hosts on some biological aspects of insect. Results obtained showed that the most preferable host to O.surinamensis was date . The highest adults emergence percentage was recorded on date , followed by rice and the lowest one was on wheat . Also , laboratory experiments were conducted to study the repellent and toxicity effect of both neemAzal -T5% Formulation (Azadirachtin) and black seed oil (Nigella sativa L.) on O.surinamensis adults. Data showed that the two compounds caused repellent and toxic effect on the adults . Adult age 1st week was more sensitive to the both tested compounds and age 3rd weeks was less sensitive . The highest mortality percentages were recorded 90.0 and 97.5 % at the highest concentrations of 75% and 1000 ppm of black seed oil after 7 days and neemAzal -T5 % at 14 days,respectively. Also , there was mortality effect on the treated 3rd larval instar . Both neemAzal Formulation and black seed oil affect as insect – growth regulator where caused highly significantly reduction in deposited eggs by exposed adults to treated media and in number of emerged adults of F1 progeny from treated media. Moreover , the total developmental period prolonged three fold as control . neemAzal -T5% was more effective than black seed oil . From these results it could be concluded that vapouration of both neemAzal -T 5% and black seed oil can be recommended for controlling O. surinamensis on stored grains.
