Angoumois grain moth, <em>Sitotroga cerealella </em>(Olivier), is one of the most important pests of such stored products as maize and wheat. Different stages of this pest were treated with ozone as a gas at three concentrations (1, 3, and 5 g/m<sup>3</sup>) for six different periods (0.5, 1, 2, 3, 4 and 5 h.) compared with untreated insects.<em> </em>The results indicated that increasing the concentration and exposure time led to increasing the rate of mortality for all tested stages at parental generation. The results showed that also, ozone affected biological aspects of the progeny resulted from treated stages (egg, larvae, pupae and adult) at F<sub>1</sub> generation.

Thirteen different species of bacteria were isolated and identified from the external body surface of <em>Musca domestica</em> collected from carrions and garbage dumps at Al Mansoureya, Giza, Egypt. The identified bacteria species were season and habitat dependent. The most frequent bacteria isolated from house flies collected from carrion or garbage in all seasons were <em>Staphylococcus</em> spp. and <em>Esherichia coli</em>. The total count of bacteria species was higher in summer season than in other seasons. Also, this count was higher on flies collected from carrion than on flies collected from garbage dumps.<em> Chrysomya albiceps</em> flies carried (11) different bacterial species on their external body surface all over the four seasons. Bacteria species were season and habitat dependent. The most frequent bacteria isolated from <em>C. albiceps</em> flies collected from carrion or garbage dumps in all seasons were <em>Staph.</em>spp. . The highest total bacterial count was recorded during spring season for bacteria isolated from <em>Chrysomya</em> flies collected from carrion. Four different bacterial species were identified on the external body surface of <em>Sarcophaga carnaria</em> in autumn 2014. The most frequent bacteria species isolated were <em>Staphylococcus</em> spp. Three different bacterial species were identified on the external body surface of <em>Lucilia sericata</em> in autumn 2014. The most frequent bacteria species was <em>Staph.</em> spp.. In general, 36 bacterial isolates from the different flies tested were identified. Bacteria species isolated from the external body surface of <em>C. albiceps</em>, <em>S. carnaria</em> and <em>L. sericata</em> were identified for the first time. The highest number of bacteria species (13) were isolated from <em>M. domestica</em> followed by (11) species from <em>C. albiceps</em>.

This study was conducted to test the effect of honeybee’s extract solution from various body phases compared with clover and citrus honey on the growth of bacteria (<em>Erwinia carotovora </em>and <em>Bacillus subtilis</em>) and Rice blast fungi (<em>Magnaporthe oryzae)</em>.
Eight samples were tested representing: drone, worker, drone larvae, worker larvae, drone pupae, worker pupae, and honey (clover and citrus honey) on the growth of bacteria and fungi. The results of the experiment indicated that honey has high activity against bacteria and fungi growth. the highest effect of extracts was in <em>Bacillus larvae</em> by worker bee extract 2.5 c.m while less impact was 1 c.m in drone pupa and worker bee extract on both types of bacteria. At the top of the fungi, effect was 77.8% by drone larvae extract while less impact was 73.3% at worker bee, larvae of worker bee, and drone pupa. Compared with clover and citrus; honey was 77.8% inhibition.

This study compared the ultrastructure of some sensor organs on the drone's antennae of Egyptian, <em>Apis mellifera lamarckii,</em> bees to that of Carniolan, <em>A. m. carnica</em>, bees. The following characteristics were compared: antennal length; number and measurements of different sensilla was studied using scanning electron microscopy. A highly significant difference was observed between the antennal length of Egyptian and Carniolan honeybee drones, with means of 3.746 ± 0.081 mm. and 4.248 ± 0.126 mm, respectively. Obtained data revealed that there were significant differences in the number of different sensilla between the two tested honeybee populations. Also, the same trend was noticed for the measurements of the tested sensor organs. It can concluded that, the highest numbers of the different sensilla appeared, is due to their important functions for honeybee social organization.

Mite survey proved the occurrence of thirty-six species of mites belonging to 30 genera in 19 families and four suborders recorded in association with different organic manures at El-Menofia Governorate during (January 2014 - January 2016). The suborder Acaridida was represented by the families Acaridae, Glycyphagidae and Chortoglyphidae. The suborder Actinedida was represented by Cheyletidae, Tarsonemidae, Bdellidae, Rhagididae, Scutacaridae, Cunaxidae, and Eupodidae. On the other hand, the suborder Gamasida was recorded by the families Pachylaelapidae, Ameroseiidae, Ascidae, Macrochelidae, Laelapidae, Uropodidae and Ologamasidae, while the oribatid mites were represented by both families Oribatulidae and Oppiidae. The most abundant family in this study was Acaridae (Acaridida) which was represented by different 5 mite species. Also, family Cheyletidae (Actinedid) was the second abundant mites group in this study and included different 4 mite species. Based on the abundance, <em>Rhizoglyphus</em> <em>echinopus</em>, <em>Tyrophagus putrescentiae</em> (Acaridida);<em> Cheyletus malaccensis, C. eruditus, Cunaxa capreolus, Eupodes aegypticus </em>(Actinedida) and <em>Kleemenia plumosus</em> (Gamasida) and <em>Oppia sticta</em> (Oribatida) were the most dominant species in this study. It was noticed that the pigeon organic manure harboured the most collected mites, which included 33 different species, while the chicken organic manures harboured 18 different mites, but the duck manure harboured 7 mite species<strong>.</strong>

Five hundred and fifty eight spiders belonging to 11 families of order Araneae were associated with <em>T. urticae </em>and collected on clover and cotton crops at Qaha research station in Qalubyia governorate, Egypt during two successive years, 2013 and 2014. During the period of study, Salticidae was the most abundant of the collected spider followed by Theridiidae, Thomisidae, Philodromidae, Dictynidae, Eutichuridae (Miturgidae), Araneidae, Linyphiidae, Lycosidae, Agelenidae, and Gnaphosidae. The number of the collected spiders, families and percent occurrence of each family varied on the studied crops in different seasons. On clover, the collected families did not include Gnaphosidae in both years of study in addition to Araneidae in 2013 and Lycosidae, Philodromidae and Agelenidae in 2014. On cotton, Lycosidae and Agelenidae were not collected in both years in addition to Gnaphosidae in 2014.
Changes of population densities of the monthly collected spiders and their prey, <em>T. urticae</em>, ran nearly in parallel during the whole seasons of cotton with peak in September and up till the prey peak on clover in March. Although the population of <em>T. urticae</em> decreased in the next months following the peak on clover, the spiders continued increasing to reach their peak in May 2013 and 2014. The total number of collected spider’s movable stages was higher in 2013 than 2014 on each crop and on cotton than clover in each year of study. On the other hand, the total number of <em>T. urticae</em> collected was higher in 2014 than 2013 on each crop and on clover than cotton in each year of study.
Laboratory studies on life stage duration, food consumption and predation rate of early immatures and adult female of <strong><em>Thanatus albini, Steatoda triangulosa</em></strong><strong> and <em>Thomisus spinifer</em></strong> (family Philodromidae, Theridiidae, Thomisidae, respectively), showed the efficacy of the three selected spider species as predators on adult <em>Tetranychus urticae</em>. Immatures and adult females of the studied spiders consumed more and lived longer when fed on females than males of <em>T. urticae.</em> In immature spiders, the number of consumed prey/spider, the daily predation rate and mostly the stage duration (except <em>S. triangulosa</em>) gradually increased by increasing age from the first to third spiderling. In female adult spiders, the 3 parameters, except predation rates of <strong><em>Thomisus spinifer</em></strong><strong>, </strong>were the highest<strong> in female <em>T. albini</em>, followed by <em>T. spinifer</em> then <em>S. triangulosa. </em>The significance of the obtained result was discussed.</strong>

Predators, parasitoids and hyperparasitoids associated with nymphal and adult stages of the cotton mealybug, <em>Phenacoccus solenopsis</em> infesting five ornamental host plants and six weeds were surveyed at Giza region, Egypt in 2015. Such study was not previously handled in Egypt. The survey revealed the presence of six predaceous species, two endoparasitoids and four hyperparasitoids. Most of the predators were recorded on the two host plants <em>Lantana camara</em> and <em>Hibiscus rosa-sinensis</em>. However, no predators were surveyed on the two infested host plants <em>Corchorus olitorius</em> and <em>Amaranthus ascendens</em>. Among the predators; the two species <em>Hyperaspis vinciguerrae</em> and <em>Scymus syriacus </em>were the most abundant. Two endoparasitoids; <em>Acerophagus gutierreziae</em> and <em>Chartocerus dactylopii</em> were served. The parasitoid, <em>A. gutierreziae</em> developed solitarily on the nymphs of its host and gregariously (2-5 individuals) on its adult stage; probably due to the host size while, <em>C. dactylopii</em> developed solitarily inside nymphs of its host.

The objective of this research was to study the abundance and prevalence of <em>B</em><em>revipalpus</em><em> phoenicis</em> and its predators on <em>Gerbera </em><em>jamesonii</em> Bolus and its relation with different weather variables during a one-year study 2015 at Ismailia Governorate, Egypt. The abundance of <em>B. phoenicis</em> life stages was monitored monthly. The effects of mite's infestation on <em>G. </em><em>jamesonii</em> morphology represented in leaf, flower, bud and flower deformity numbers during spring was considered, in addition to the photosynthetic pigments. Our results revealed great variations in mite population throughout the year. The highest density of<em>B. phoenicis</em> adults, eggs, larvae, nymphs were recorded in January (50.25±6.08), May (71.85±8.57), January (31.40±4.71), July (74.43±8.73), respectively while the minimum density were recorded in October (4.10±0.83), September (10.30±2.09), August (1.95±0.46) and (16.10±2.50), respectively. Three predacious mites: <em>Amblyseius cucumeris</em>, <em>Hemicheyletia wellsina</em>, <em>Tydeus</em> sp. and one predacious insect<em> Scolothrips longicornis</em> were recorded.Negative correlations was recorded between <em>B. phoenicis</em> eggs or larvaewith <em>S. longicornis</em> (-0.122, -0.168), respectively. Significant negative correlations were observed between different <em>B. phoenicis </em>life stages, <em>Tydeus</em> sp. and <em>S. longicornis</em> with temperature and relative humidity. There were significant negative or positive correlations between life stages of <em>B. phoenicis</em> and the morphological characteristics of the plant. Highly significant negative correlation was recorded between mite infestation and photosynthetic pigments. In conclusion, <em>G. </em><em>jamesonii</em> is recorded as a new host for <em>B. phoenicis</em> with a marked deformation in the plant morphology. In addition environmental factors had a great effect on its abundance.

Our local traditional herbal and medical plant may be interduce alternative bio material alter the biology of the red spider mite <em>Tetranychus urticae</em> Koch. The present study was conducted to determine the direct and residual effects of the two natural plant extracts, aerial parts of<em> Artemisia vulgaris</em> L. and the seeds of <em>Acacia concinna</em> (Willd.) using soxhelt extractor, against the two spotted spider mite, <em>Tetranychus urticae</em> Koch, at the laboratory controlled conditions, 30±2C° and 70±5% RH. Two concentrations, 0.25% & 0.5% were utilized to study its effects on the biological aspects of <em>T. urticae</em>. The results confirmed the effective influence of these extracts on mite life aspects, which altered and prolonged the mite life cycle, and that reduced the number of generation/year. Moreover, the used extracts also achieved of high mortality percentages, reached 65.52% and 51.72% in pre-oviposition period and oviposition period respectively, when treated with the highest concentration of <em>Artemisia</em> extract. Reduction in hatchability achieved 61.11%, 57.11%, 54.11% and 52.11% for <em>Artemisia</em> 0.25% & 0.5% and <em>Acacia</em> 0.25% & 0.5% respectively.

Field trial was conducted during two successive seasons on 2015 and 2016 at greenhouse experimental area, Dokki, Giza Governorate. This study aims to evaluating the efficiency of different colors mulch and some environmental factors on reduction of population density to the main sap-sucking pests infesting cucumber and yield. The trial were used five colors mulch to covering soil, i. e., red, green, blue, white, yellow and Control treatment without mulch. The results revealed that there are significant differences between using colors mulch with population densities of some pests the whitefly, <em>Bemisia tabaci</em> (Genn.), the thrips, <em>Frankliniella intonsa</em>( Trybom) and the spider mite, <em>Tetranychus urticae</em> (Koch ). The tested mulch colors could be arranged according to population density of pests into six ecosystems. The red and white colors was the most potent treatments in low population pests in cucumber plants followed by blue, control, yellow and green which was the highest mean number of infestation in both seasons. Maximum and Minimum temperature were showed insignificant positive effect in first season but Minimum temperature was showed significant positive on <em>B. tabaci</em> (egg and nymph) during second season. Maximum and Minimum temperature were showed insignificant positive effect with <em>F. intonsa</em> and <em>T. urticae</em> (egg and immature) at the both seasons. The relative humidity had insignificant negative effect on <em>B. tabaci, F. intonsa</em> and <em>T. urticae</em> at the both seasons. The soil temperature had insignificant negative effect on <em>B. tabaci, F. intonsa</em> and <em>T. urticae</em> at the both seasons. The combined effect (E.V) of these ecological factors on <em>B. tabaci</em> (egg and nymph) , <em>F. intonsa</em> and <em>T. urticae</em> (egg and immature) showed that these factors were responsible as a group for 94 % , 79 %, 83, 89, 98, 87, 99, 99, 93, 95 effects on the population dynamics of pests throughout both seasons, respectively. Especially infestation pests - Yield relationship, the mulch colors affect 75% and 82% in yield weight both seasons.
<strong>Recommendation:</strong> the paper recommendation by cover soil surface with red and white mulch to reduce population of whitefly, thrips and red mite and increase yield.

Green <em>pea Pisum sativum,leguminasae </em>is one of the most popular vegetable crops in Egypt. It is liable to be attacked by several destructive pests that cause great yield damage, which can result in greater than 50 %yield reduction. Many insect pests belonging to the different orders, such as <em>Liriomyza trifolii</em> (Burgess)<em>, </em>white fly<em> Bemisia tabaci </em>Genn and red spider <em>Tetranychus urticae</em>. The goal of the present work is to determine the population activities of certain pests infesting Green pea as well as the numbers and duration of seasonal field generations. The combined effects of some climatic factors on the tested insect pests also were studied<strong>. </strong>Experiments were conducted at Manawat district, Giza Governorate on the autumn's of 2014 and 2015 seasons. The relationship between the minimum, maximum temperatures and relative humidity average as well as the age of plants against the population of the target pests infesting on the leaves of green peas were studied in 2014 and 2015

<span style="line-height: 115%; font-size: 10pt;">The field experiments were carried out at El-Berka village, Abu-Hommus, El-Beheira Governorate, Egypt during three Nile successive seasons, 2013, 2014 and 2015 to evaluate the susceptibility of potato cultivars to <em>Polyphagotarsonemus</em> <em>latus</em> and to throw light on population build up in relation to weather factors distribution within the potato plants. Present data showed that the high infestation of <em>P. latus</em> was recorded in October and November on the tested potato plants.</span>
<span style="line-height: 115%; font-size: 10pt;">The highest susceptible cultivars were represented by Spunta with mean number of 6.10 ±1.02 individuals /leaflet.The Moderate susceptible cultivar was represented by Sanura (3.66 ±0.59 individuals /leaflet). The lowest susceptible cultivar was represented by Pampa (3.60 ±0.34 individuals /leaflet).</span>
<span style="line-height: 115%; font-size: 10pt;">The results reflected that maximum, minimum and mean temperatures had negative effect on mite population. However, maximum, minimum and mean relative humidity and plant age had positive effect with the mite population on all potato varieties. The temperature, relative humidity and plant age were common factors affecting the development rate of various stages of mites.</span>
