Abstract. All studies were conducted during the years 2020-2021 in the village of Kzo and its environs of Dohuk Governorate / northern of Iraq, the results of the survey led to the collection of 42 samples, Samples which all belongs to the genus Xylocopa , Six samples represent four species from all samples were sent to Dr Munazah Associate Professor, Department of Entomology, University of Agriculture and Science and Technology of Kashmir, India for classification , The result of classification showed that three of them were belong to the sub-genus Xylocopa represent two species,one male of species Xylocopa varentzowi The main character is that the front legs were contained a dense group of long white hairs on the outer part of the tibia, Male and female of species Xylocopa violacea the female were contained a density of black hairs on the front legs and more on the hind legs,The males of this species are distinguished by their antenna, in which the flagella consists of 11 segments and its segments is brown, but the ninth and tenth segments (9-10) which were characterized by their yellowish-orange color,and the other three specimens were belong to the sub-genus Proxylocopa represent two species, one female of species Xylocopa rufa were characterized by the calyx sita or hairs which covering edges of the abdominal region which were interrupted and unconnected in the middle, male and female of species Xylocopa olivieri were characterized by the hairs which were covered the edges of the abdominal tergit segments, pale yellow color, continuous and unbroken in the middle, The results of phenotypic studies of male and females samples of the four species Xylocopa varentzowi, Xylocopa violacea, Xylocopa rufa and Xylocopa olivieri is reported for the first time from the high altitudes of Duhok Governorate( more than 1,140 m above sea level), Iraq.

Abstract. Broccoli (Brassica oleracea L.) belongs to the family Brassicaceae, is a cool-season crop that can be grown year-round under controlled greenhouses conditions. And the results showed that the plant was attacked by many pests causing direct damage to the crops. As cabbage grey aphid (Brevicoryne brassica L.), cabbage white butterfly(Pieris rapae), great white butterfly (Pieris brassicae), diamondback moths (Plutella xylostella), cabbage cutworm( Agrotis ipsilon), and Grasshopper (Melanoplus sp.), and using sticky traps have been efficient in controlling the density of these pests and can be applied within the integrated pest management, so their use avoids damage to the crop. The traps were superior in reducing the insect’s infected percentage to (4, 0,2,3,3,2 )% respectively, as well as in the effect on the quantity and quality of the yields obtained, where the highest production was recorded, amounting to approximately 1200kg/greenhouse and the absence of the need to use chemical pesticides compared to the control (without traps), where the production reached 700 kg/ greenhouse.

Abstract.The study showed the effectiveness of the aqueous extracts of seven plant species for Clovebuds (Syzygium aromaticum), Garlic seed (Allium sativum), Thyme leaves (Thymus vulgaris), Eucalyptus leaves (Eucalyptus oleosa), Sage (Salvia officinalis), Black Arum leaves (Eminium spiculatum), and Red hot pepper fruits (Capsicum annuum) with five different concentrations (1.5, 3, 5, 7.5 and 10) % in some aspects of biological performance of the Khapra beetle larvaeTrogoderma granariumEverts. The aqueous extract of sagebrush showed the highest lethal effect, as the mortality 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 attract effect and clove extract gave highest attraction rate by 73.33%

Abstract.In this study, 24 Awassi rams were used at the age of 1.5-2 years, with an average weights of (46.4±1.2 kg) to study the effects of supplementation some antioxidants on hematological and biochemical blood parameters of Awassi rams , The rams were randomly allotted into four groups of equal number (6) rams each group , the first group (control) , the second group was given turmeric at the rate of 3 g / kg feed / head daily, the third group was supplemented orally with 400 IU vitamin E / head three times weekly , the fourth group was supplemented orally with 400 mg CoQ10 coenzyme / head three times weekly , these materials were given to the rams of each treatment before providing the daily feed, The experimental animals were given a standardized diet consisting of ( concentrated feed + Wheat Straw ) on the basis of 2.5 % of live body weight . The percentage of protein in the diet was 15.22% and the metabolic energy was (2721.5) kcal / kg of feed. The weights of the animals were measured and bloodsamples were drawn from the jugular vein monthly to measure the characteristics of the physical and biochemical parameters of blood serum. The results of the study showed a significant (p≤0.01) effect of the treatments on the characteristics of the animal’s weight, number of WBC, the percentage of eosinophil's and basophils than control group , while the treatments did not show a significant effect on the other blood values. The results also showed a significant (p≤0.01) effect of the treatments on the levels of total protein, cholesterol, triglycerides, globulin and urea, in addition to the levels of HDL, LDL , while there was no significant effect of the treatments on the concentration of glucose, albumin, VLDL in the blood plasma. Through the results ofthis study, we conclude that giving antioxidants to rams had a positive effect on some physical, biochemical and enzymatic parameters of blood in the treated groups compared to the control
