Abstract
Blue coloured traps, plant traps and plant extractions (Neem Azal formulations) were evaluated as a means of control against Tropinota squalida in Sharkia and Ismailia Governorates during 1995/96 and 19961 97. The blue traps were more efficient than pan blue water traps for mass trapping adults of these suppressing population density of the target pest. Plant traps (Canola) was used as a plant trap in intercropping system with wheat or broad bean. The highest attracting effect was achieved 85.27% at the ratio of intercropping 3 canola/7 wheat, while the attraction of canola by 2, 3, 4 were nearly similar, therefore the suitable intercropping system with 2 caonla/8 wheat was considered as the best ratio for trapping T. squalida. Canola with broad bean was the most effective intercropping ratio at rate of 2 canola/8 broad bean. In this ratio, the attraction reached 24% of the total number of beetles attracted to the plot. The repellent effect of two Neem Azal formulations (T.s 1% & T 5%) on adult attraction to flowers was evaluated during 1995 & 1997 on 3 fruit trees, 3 field crops and will mustard. Beetles were counted visually after 1, 2, 5, 7 and 11 days after application in both treated and untreated plants. Neem application on these host plants gave adequate protection for 5-11 days depending on the population density of both host plant flowering and the attracted adults.
