Broccoli (Brassica oleracea) is a cool-season crop that can be grown year-round under controlled conditions such as greenhouses. And the results showed that it was attacked by many pests causing direct damage to crops. As cabbage grey aphid, cabbage white butterfly, great white butterfly, diamondback moths, and cabbage cutworm, and using stick traps have efficient in controlling the density of pests and can be applied within the integrated pest control, so their use avoids damage to the crop. The trap was significant and superior in monitoring and recording the first appearance of the insect pest, as well as in the effect on the quantity and quality of the product obtained, where the highest production was recorded, amounting to approximately 1200kg/greenhouse and the absence of the need to use chemical pesticides for control compared to the control (without traps), where the production reached 700 kg/ greenhouse.

The study showed the effectiveness of the aqueous extracts of seven plant species for Clove buds (Syzygium aromaticum), Garlic seed (Allium sativum), Thyme leaves (Thymus vulgaris), Eucalyptus leaves (Eucalyptus oleosa), Sage (Salvia officinalis), Alaaya leaves (Eminium spiculatum), and red hot pepper fruits (Capsicum annuum) with five different concentrations (1.5, 3, 5, 7.5 and 10) % in some Biological aspects of the Khapra beetle larvae Trogoderma granarium Everts. The aqueous extract of sagebrush showed the highest lethal effect, as the killing rate was 100% at a concentration of 5%, and toxicity index and toxicity efficiency amounted to 100, 28, and 23, respectively, compared to the rest of the studied plants. It was noted that the aqueous extracts of plants sagebrush and sagebrush tested showed the characteristic of repelling insects and that the sagebrush plant gave the highest repelling rate of 63.33%, while the plants of garlic, hot pepper, cloves, thyme, and eucalyptus showed the characteristic of attraction and that the aqueous extract of cloves gave the highest attraction rate of 73.33.
