Monitoring of insect population in fields is one of the essential demands for the integrated pest management programs. Therefore, the experiments were carried out at EL-Zarkia village, Zagazig district, Sharkia Governorate to monitor the population of green stink bug Nezara viridula L. infesting two varieties of maize (Zea mays L.) for two consecutive growing seasons 2008 and 2009. The study aimed to investigate the effect of maize sowing date, varieties (Triple hybrid and Balady), cardinal directions and adjacent crops on N. viridula infestation. Also, the control of this pest using some conventional insecticides comparing with certain alternatives was also studied and the results could be summarized as: 1. Triple hybrid variety was more suitable for the insect than the Balady variety. 2. The early sown plants were more suitable to infest with the pest than the late ones. 3. The population of insect existed in lower numbers in the S9uth direction of the field than the other three sides. 4. The insect population existed in higher numbers at the edge and the middle area of the field. 5. The maize plants when sown alone harbored the reliable occurrence of the insect. 6. Dursban, Sumithion and Kendo showed a high efficiency against nymphs and adults while Detergent was the least effective. Bio-neem took intermediate position. 7. Plots treated with Sumithion, Dursban and Marshal produced the highest yield followed by that of Marsal, Aphox and Malathiomix. Generally, these results are important in the integrated pest management programs of this pest in maize fields to direct the suitable. control measure to the infested spots, thereby, the environmental hazards and costs are minimized.
