Water pan traps, or what is known as Moericke traps, are pans coloured in order to attract many insects to them. They are one of the most important successful techniques used to collect insects in various ecosystems. This research was conducted to study the effect of the colour and location of water pan traps on the abundance and diversity of insects collected from the Research and Experiment Stations of the Faculty of Agriculture - University of Tripoli, during February and March, 2016. Water pan traps of yellow, orange and blue colour in the form of a flower bowel were used. These pans were placed at ground level on a wooden board, and in ten different vegetation locations at the Research Stations, each board was containing six plastic bowels, (two/colour), and a salt solution was placed in each pans. Samples were collected weekly, sorted and labeled in the laboratory. The results showed that the number of insects collected during the month of March higher than month of February (9000:5197). The collected insects are represented in 12 orders (Diptera, Coleoptera, Hymenoptera, Neuroptera, Lepidoptera, Thysanoptera, Hemiptera, Homoptera, Orthoptera and Colembolla)،from all locations. Insects from the order of Psocoptera collected one time from location (2). Also, the number of insects from the order of Diptera was more in February than in March, whereas insects from the order of Orthoptera were collected in the month of March. The results also showed that the yellow traps were more attractive to insects especially order Diptera, followed by the blue especially order Hymenoptera and then the orange which collected order Homoptera.
