“…-Proximate nutritive values of DPP: In this study, palm pollen grains were analyzed for their constituents of moisture, total solids, fiber, ash, crude fat, total protein and carbohydrates. The obtained data are given in table (2). Which indicate that moisture content of palm pollen grains was 8.041 ± 0.1%, this value was less than 28.80% (5) and higher than (3.6-4.8)% obtained by Bacha et al (31) , while the total solids was 91.959 ± 0.1 % and this value is higher than 71.2% (5) .…”

The pollen of date palm -DPP (Phoenix dactylifera L. variety El- Ghannmi Ahmar.) has been analyzed for the main phytochemical composition , nutrient and mineral composition. The phytochemical screening of chemical constituents of the plant showed that the DPP grains contains phytosterols, flavonoids, alkaloids, protein, carbohydrates, glycosides, phenolic compounds, tannins, terpenoids, saponins, coumarins, lignin, oil and fats, with absent of quinones. The quantitative contents of alkaloids, tannin, phenolic compounds and sterols were (2416±0.034, 2279.6±35.769, 115±5 and 110.1±0.87) mg/100g in DPP grains. While the moisture content of palm pollen grains was 8.041 ± 0.1%, and 91.959 ± 0.1 % for the total solids. Values 0.113±0.003 % and 5.585 ± 0.144 % were estimated for crude fiber and ash contents respectively. Crude fat content of DPP grains was 7.678 ±0.149%, 19.45%, for crude protein and 26.25±0.315 g/100g for carbohydrates ,the energy value was 291.902 Kcal/100g. The predominant minerals were potassium 73.5 mg/g, followed by magnesium 19.6 mg/g , calcium 10.8 mg/g and iron 8.5 mg/g. Comparable amounts of sodium 4.34 mg/g and copper 3.658 mg/g with equal amounts of molybdenum, nitrogen and boron (3.169, 3.11 and 3.024) mg/g respectively were found in DPP grains. Palm pollen also contain useful amount of zinc 2.799 mg/g, manganese 2.702 mg/g, selenium 2.51 mg/g, cobalt 1.986 mg/g, nickel 1.698 mg/g and cadmium 0.12 mg/g. From all the results we can conclude that the date palm pollen was as rich source of antioxidant, energy, and important minerals, so its suitability as a regular component in human diet.

A total of 43 insect species non-native to Europe are so far considered to affect human welfare through their biting, urticating and allergenic properties, or by causing domestic nuisances. They involve several orders. In Hymenoptera, species in two families, Formicidae (ants) and Vespidae (wasps and hornets), are known to cause disturbance and health problems. Several moth species (Lepidoptera) have urticating larvae which may induce painful urticarial and allergic reactions. Bugs in five Hemipteran families have direct impacts on health, such as bed bugs and kissing bugs, which are vectors of pathogens, but most are considered to be household pests, causing nuisances to people when invading houses or aggregating on walls. Several non-native species of cockroaches that develop in synanthropic habitats have body parts, saliva or faeces containing powerful indoor allergens, and they can also facilitate mechanical transmission of pathogens to humans. Some species of Siphonaptera (fleas) and Phthiraptera (lice), which are obligate ectoparasitic insects of warm-blooded animals, are of high importance for human health because they cause itches and skin infection, and transmit major diseases such as bubonic plague and murine typhus.

Date palm pollen-DPP (Phoenix dactylifera L) plays an important role in traditional treatment in Iraq, especially for the treatment of fertility or as supplements, flavonoids were important components for date palm pollen, no information is available in the literature about the types of flavonoids in an Iraqi DPP variety El-Ghannmi Ahmar. The HPLC analysis revealed that in an Iraqi DPP variety El-Ghannmi Ahmar contains many types of flavonoids (13.590 µg/g lincoceric acid, 122.251 µg/ gIsorhamnetin,71.146 µg/g chlorogenic acid, 99.188 µg/g ferulic acid, 64.574 µg/g naringin, 109.117 µg/g apigenin, 48.391 µg/g apigenin-7-O-beta glycopyranoside, 28.883 µg/g letulin and 18.291 µg/g letulin-7-O-beta glycosides).
