| Abstract:
A greenhouse experiment was carried out to evaluate the insects trapping efficiency of various colored traps in cucumber (Cucumis sativus L.) crop in Riyadh, Saudi Arabia. The treatments involved were seven different sticky traps (green, fluorescent yellow, orange, pink, red, yellow and transparent (control)) placed at four different heights (0.5, 1.0, 1.5 and 2.0 m above the ground) and each treatment was replicated four times. The experiment was laid out in a complete randomized block design. The insect pests recorded were thrips Thrips tabaci (Lindeman) and the leafminer Liriomyze trifolii (Burgess). A significantly higher number of insect pests was trapped on fluorescent yellow traps as compared to other coloured traps. The pink, green and orange colored traps caught a significantly lower number of insects and were statistically similar. However, there was no significant difference between the mean number of various insects caught on sticky traps placed at different heights from the ground level but more insects were trapped at maximum height (2 m). | |
