Ecological studies of Aulacaspis tubercularis (Newstead) (Diaspididae: Hemiptera) and its natural enemies were carried out during two successive years (2007-2008 and 2008-2009) in Inshas El- Raml district, Sharkia Governorate, Egypt. The obtained results revealed that the total number of alive stages had one peak of activity yearly in both top and bottom levels of the trees. Aphytis sp. and Encarsia sp. (Aphelinidae), Habrolepis diaspidi (Risbec) (Encyrtidae) were recorded as parasitoids of A. tubercularis. Cybocephalus micans Reitter (Order: Nitidulidae) was recorded as predator of A. tubercularis. The total effects of a biotic factors (Temperature ºC, Relative humidity RH% and Light intensity Lux) under this study on the total numbers of alive stages of the pest during the two years were 63.19 and 40.20 % in the top level and 77.66 and 39.44 % in the bottom one, successively. The pest activity appeared three annual generations in either the top and bottom levels of mango trees.

A survey of armored, soft scales and mealybugs (Hemiptera: Coccoidea) infesting the ornamental plant species Hedra canariensis in Montazah garden was carried out in the years of 2005-2007. The results revealed the occurrence of two armored scales: Mycetaspis personata (Comstock) and Aspidiotus nerii Bouché (Hemiptera, Diaspididae),two coccid species named: Pulvinaria psidii Maskell (Hemiptera, Coccidae),and Coccus hesperidum (Linnaeus) (Hemiptera, Coccidae) and one pseudococcid species: Planococcus citri (Risso) (Hemiptera: Pseudococcidae). Considering the armored scale group, the highly abundance was recorded during January and February (75 and 83.4 % of grand total count) in the first year and in February (77.8 %) in the second year. The lowest abundance was recorded during July in two successive years. Regarding the population count of soft scale group, it’s clear that the highest rate of these coccids was observed during July and August during the first year while in the second year this rate reached 94.0% during July only. The lowest rate of soft scale recorded during February in two years (16.4 and 22.2 % of total count in respect). The scarcely inspected citrus mealy bug individuals; P. citri was found in low numbers, while disappeared completely during the elapsing spring-summer months from April till August or / and September; and early winter month of January or / and January-February in the 1st or / and 2nd years, respectively.

Studies on some ecological aspects of Kilifia acuminata (Signoret) (Hemiptera: Coccidae) and its parasitoids on mango trees were carried out in Inshas El- Raml district, Sharkia Governorate, Egypt during two successive years (2007-2008 and 2008-2009). The obtained results revealed that total alive stages had two to three peaks of activity yearly in both top and bottom levels of the trees. Metaphycus sp. and Coccophagus sp.were recorded as parasitoids of K. acuminata. The pest activity appeared three generations annually either in the top and bottom levels of mango trees. Each generation was lasted about 4 months. They periods were from March to June, July to October and November to February, respectively. The total effects of a biotic factors (Temp.ºC, RH% and Light intensity Lux) under this study on the total numbers of alive stages during the two years were 84.17 and 38.30 % in the top level and 85.87 and 43.76 % in the bottom one, successively. Preferable level and preferable leaf surface of K. acuminata and its associated parasitoids were studied.

Suppression of white mango scale, Aulacaspis tubercularis (Hemiptera: Diaspididae) on mango trees in El-Beheira Governorate, Egypt.
Abo-Shanab
H.
White mango scale, Aulacaspis tubercularis Newstead (Hemiptera: Diaspididae) is a serious pest on mango (Mangifera spp.), (Sapindales: Anacardiaceae) which became recently a troublesome pest in all mango orchards in Egypt. It causes fatal damage especially to late cultivars by sucking leaves which turn pale-green or yellow and ultimately die or fruit causing conspicuous pink blemishes around insect feeding sites resulting in external lesions rendering it unmarketable for export. Seasonal abundance was estimated throughout 2 successive years (2008 and 2009) and showed that the white mango scale (A. tubercularis) had four peaks for its population density during the two studied years, (April, August, October and December, 2008) and (March, July, September and December, 2009). Study of weather factors, [daily mean temperature (oC), relative humidity (%), dew point (oC) and wind speed (Km/h)] effects on A.tubercularis population density illustrated that there was significant positive relationship between (daily mean temperature and relative humidity) and counted population density, but there was a significant negative relationship between (wind speed and dew point) and counted population density. Two successive field experiments for eight weeks during early spring (2009 – 2010) aimed to test some summer/light mineral oils, (super masrona®, CAPL2® and Diver®) against A. tubercularis on mango trees. The tested mineral oils were effective by the following descending order : Diver > CAPL2® > super masrona® without significant differences between diver and CAPL2 and significant differences with super masrona, with the same effective trend and same statistical means, during the two seasonal experiments. The study recorded a little numbers of natural enemies (Parasitoids (Aphytis mytilaspidis (Le Baron)andEncarsia citrina (Craw) (Hymenoptera: Aphelinidae)), and predators (Chilocorus bipustulatus (L.) andScymnus syriacus Marseul (Coleoptera: Coccinellidae)). It may be killed by previous bad history of chemical insecticides usage in this area.

The performed inspection on the leaves ofFicus nitida hawaii (Moraceae) was carried out in Montazah garden during two successive years (June, 2005 till May, 2007). The observed scale insect infesting leaves is Mycetaspis personata (Comstock) (Hemiptera: Diaspididae). Results concerning the monthly variations in the total monthly counted individuals of the masked scale, M. personata per 5 trees throughout the period of study revealed the presence of five highly variation periods in the first year, one in summer, two during autumn months, one in winter months as well as one took place in late spring. While, in the second year the obtained data revealed that there were six highly variation periods, one in summer, two during autumn months, and two during winter as well as one in late spring. In the first year the number of adult female reached the maximum of total population during July (100% of the total counted insect), then decreased to 68% of the total count during October, increased to 72% in November, decreased again to 66% of total count in December, reincreased slightly to 69% in March then re-decreased to 62% in April and reached the maximum 94% of total count in May. Similar trend of results was also observed in the second year. A field experiment was conducted to control M. personata using tow mineral oils: [Masrona® (heavy oil) and Super Royal(R) (light oil)] and an insect growth regulator (IGR), Ropest®. The data obtained revealed that no significant difference between the tested materials on the reduction of population count of the insect. On the other hand, the light oil, S.Royal gave least reduction percentage of the parasitoid Aphytis mytilaspidis (Le Baron)(Hymenoptera: Aphelinidae)while Masrona oil gave a best result on reduction of predacious mite, Tydeus californicus (Banks) (Tydeidae : Acari ).

The red-striped soft scale insect, Pulvinaria tenuivalvata (Newstead) (Hemiptera : Coccidae) is a serious pest on sugarcane. As a basic study for developing future management of this scale species, seasonal activity of different stages of this insect was carried out through two successive seasons (2006/2007 and 2007/2008) at Esna district, Qena governorate. The obtained results showed that, P. tenuivalvata had four peaks occurred in mid of July, mid-September, beginning of November and beginning of December per season. The second season of study cleared that the total population of this insect was higher in comparison to the first season of investigation, which may due to the influence of favourable factors. The combined effect of the tested weather factorswas responsible about some in the total population. The percentages of explained variance (E.V.) indicate that all tested variables were together responsible for (30.6 and 42%) during the two seasons of study, respectively.

Lepidosaphes beckii (Newman) (Hemiptera: Diaspididae) seasonal abundance on sour-orange, Citrus aurantium trees was carried out in Kafr El-Sohaby, at Qalubyia Governorate, Egypt, starting April, 2004 to March 2006. Population dynamics indicated mean population as 46.25, 49.20 individuals/leaf over 2004/2005 and 2005/2006 years, respectively. The mean number per leaf was 4.97, 18.96, 5.97, 8.06 and 8.30 individuals for crawlers, pre-adults, females, gravid females and male pupae, respectively over 2004/2005. The relative means were 7.51, 21.30, 5.56, 8.93 and 5.90 individuals/leaf, for 2005/2006, respectively. Both north and east directions harbored the heaviest infestation (i.e. 64.4 and 61.6 scales/leaf for north and 49.7 and 62.2 scales/leaf for east over the two years, respectively). The upper leaf surface harbored heavier infestation compared with the lower one in both years. Four generations per year for L. beckii were determined in this location using age-structure method (i.e. percent proportion of each stage population over the total).The first generation extended from Jun. 3, to Aug. 12, 2004. The second generation started there after and continued until Oct. 21, 2004. Third generation continued until Feb. 24, 2005. The last generation started Feb. 24, 2005 and continued to Jun. 10, 2005. This means that both first and second generations continued over 70 days each compared with the third generation which continued for 126 days. The fourth one continued over 106 days. Similar results were obtained for the second year (2005/2006). Three periods for chemical control of this pest on citrus at this location was recommended (where the relative abundance of immature stages was the most). The first period was during Apr. 15 to 30. The second was Jul. 15 to 30 and the third during Sept. 15 to 30. The parasitoids recorded from L. beckii on sour-orange were the primary parasitoid Aphytis diaspidis Howard (Hymenoptera: Aphelinidae) and the secondary one, Chartocerus niger (Ashmead) (Hymenoptera: Signiphoridae). Parasitism by A. diaspidis ranged between 0 to 24.6% with mean of 11.9% over the two years.

Nine scale insect species (Hemiptera: Coccoidea) belongs to four families were collected during updated survey at Qaliobiya Governorate for two successive years. A key with photographs and illustrations are introduced; the seasonal fluctuation and the population density of all stages of the most serious soft scale insect, Pulvinaria psidii Maskell(Hemiptera: Coccidae)were studied in relation to five main weather factors. Three predators, Rodalia cardinalis Mulsant, Chilocorus bipustulatus L. (Coleoptera: Coccinellidae) and Amblyserius swiriskii (Athias-Henriot) (Acari: Phytoseiidae) were collected associated with P. psidii and their effect with the other meteorological factors are analyzed statistically using partial regression method to decide their contemporary effect. The half monthly variation was calculated and the number of generations of this soft scaleper year were estimated throughout the two successive years of investigation to indicate the high infestation of this pest to reach 327 insect/ leaf at 1st may, the lowest population density were during winter season. The efficacy of the alternative pesticides (Biological insecticides, mineral oils, IGRs) andorganophosphorus insecticides for controlling this serious pest different stages during summer and winter field sprayings were applied to insure that: the summer spray was more effective than the winter spray, the mineral oils and soap gave high efficacy after two weeks of spraying and still increasing till the end of the experiment, without observed phytotoxicity; IGRs and biological insecticides started to give good efficacy after one month of spraying and also still to increase till the end, in addition to their safety effect, opposite to the synthetic insecticides that gave a very good efficacy at the beginning of the experiment and decreased gradually. Finely the application time is very important; the organophosphorus compounds must be replaced by these other friendly alternatives; rearing and releasing these predators must be used in this pest control management.

The cottony camellia scale, Pulvinaria floccifera (Westwood) (Hemiptera : Coccidae) is considered one of the most important pest infesting different crops in Egypt. The aim of this work is to study the survey of host plants and natural enemies of the cottony camellia scale P. floccifera in Egypt as well as the biological studies of the cottony camellia scale P. floccifera on citrus, fig and guava. The obtained results indicated that the list of host plant including 12 species recorded infested the cottony camellia scale, P. floccifera. Seven species recorded here for the first time in Egypt. Also, the updating lists including 14 parasitoid and 17 predator species, four and five species of parasitoids and predators recorded here for the first time in Egyptassociated with the cottony camellia scale, P. floccifera, respectively. Temperatures greatly influenced the development of P. floccifera. The lowering of the temperature increased the dimension of the cottony camellia scale and prolonged the developmental period. The results on citrus, fig and guava showed that the life cycle of P. floccifera at 30oC were 71.5±5.75, 80.7 ±5.00 and 58.7±0.35 days, respectively. These results indicated that the cottony camellia scale, P. floccifera prefers guava, followed by citrus and fig.

Five insecticide compounds Azadirachtin (Nimbecidine®); Pyriproxyfen (Admiral®); Acetamiprid (Mospilan®); Emamectin benzoate (Proclaim®) and summer mineral oil (star oil®) and their mixtures were evaluated for controlling the purple scale insect, Lepidosaphes beckii (Newman) (Hemiptera: Diaspididae) as well as its parasitoid Aphytis lepidosaphes Compere (Hymenoptera: Aphelinidae) on growing citrus orchard, Citrus sinensis L. (Rutacea). This work has been carried out in the experimental farm of faculty of agriculture, Sabahia, Alexandria, Egypt, during two successive seasons 2009 and 2010. The obtained results revealed that star oil® in combination with Admiral® and Nimbecidine® have given the highestreduction (%) values for L. beckiiand its parasitoid, A. lepidosaphes during the two experimentally years. In 2009, the calculated reduction % values for L. beckii and A. lepidosaphes were (99.78 and 99.50%) and (96.75 and 97.29%), whereas in 2010 were (99.73 and 99.34%) and (94.40 and 96.46%) for the two combinations, respectively. On the other hand (Mospilan®) and (Proclaim®) show less reduction percentages to the parasitoid during the two successive years. Whereas in 2009 were 54.56 and 73.19 %, in 2010 were 43.47 and 71.25 %, respectively.

Taxonomy of scale insects in Egypt (Coccoidea: Sternorrhyncha: Hemiptera)
Mohammad,
K.
Moharum
A.
The results can be summarized as follows:
1- The Egyptian scale insects fauna includes thirteen families: Aclerdidae, Asterolecaniidae, (Coccidae), Dactylopiidae, Diaspididae, Eriococcidae, Halimococcidae, LecanoDiaspididae, Margarodidae, Monophlebidae, Ortheziidae, Phoenicococcidae, and Pseudococcidae.
2-The number of species of superfamily Coccoidea presented in Egypt only is 22; in 9 families.
3-The collection of the Plant Protection Research Institute is the largest in Egypt and it includes more than 4800 slides. The collection started in 1921 until 1993. This enormous work is attributed to Hall, Ezzat, Prisener and Hosny.
4-The authentic material in the Collection of Plant Protection Department, Ministry of Agriculture, Egypt amount to 47 Species.
5-Type depository ( Holotype female, Syntypes female , Syntypes, female, male and first instar, Lectotype, Lectotype fossil) of 67 Egyptian species are present in 7 museums: The Natural History Museum, England; United States National Entomological Collection, National Museum of Natural History, USA; Bet Dagan: Department of Entomology, The Volcani Center, Israel; Museum National d'Histoire naturelle, France; Zoological Museum, Academy of Science, Russia; The Bohart Museum of Entomology, University of California, USA; Naturhistorisches Museum Wien, Austria.
6-The Natural History Museum, England, UK. includes 49 species which represent about ¼ of the total number of species in Egypt.
7- The generation of scientists in Scale Insects started with Hall in 1921 who established taxonomy in Egypt. The number of researchers in this field reached 16 until present. It is important to note that Prof. Yehia Ezzat has a great number of publications in this field and contributed extensively to continuing these studies in Egypt. In addition, there are three foreign scientists who published two papers on species present in Egypt in 2010.
8- The importance of Taxonomy of Scale Insects is due to the fact that scale insects can usually only be identified, in order to be controlled, when stained and mounted on glass slides. Also, taxonomy of Scale Insects helps in agriculture quarantine.

Olfaction in Coccoidea (Hemiptera)
Abdel-Razak
S.
Dewer
Y.
The insect olfactory system has become a very important model of sensory function, morphology and development. The understanding of the molecular mechanism of insect olfaction will help in the development of insect attractants and repellents for controlling insect pest and vector populations for a wide range of pathogens. This essay aims to explain the importance of understanding how insects 'smell' and how the chemical signals are recognized is useful for many things, but especially for modern pest control in agriculture.

El-Sahn,
N.
The scale insects are small insects of the order Hemiptera, generally classified as the Superfamily Coccoidea. There are about 8,000 species of scale insects. Scale insects feed on a wide variety of plants, and scale species are considered pests. This review article is presenting the ecological aspects of some important scale insects and mealybugs infesting horticulture plants in Egypt. Armored scale insects (Hemiptera: Diaspididae) like Aulacaspis tubercularis Newstead, Pseudaulacaspis pentagona (Targioni-Tozzetti ), Parlatoria oleae (Cloveé), Parlatoria ziziphi (Lucas), Fiorinia phoenicis Balachowsky and Hemiberlisia lataniae (Signoret). While, the soft scale insects (Hemiptera: Coccidae) showed by Pulvinaria tenuivalvata (Newstead), Pulvinaria psidii Mask., Saissetiacoffeae (Walker) and Ceroplastes floridensis Comstock. In case of mealybugs was represented with Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae), Icerya seychellarum (Westwood) (Hemiptera: Monophelibidae) and Ferrisia virgata (Cockerell) (Hemiptera: Pseudococcidae). Family: Asterolecaniidae exampled by Asterolecanium pustulans Ckll. (Hemiptera: Asterolecaniidae).

The infectivity of three Egyptian Heterorhabditid nematode species Heterorhabditis bacteriophora (Poinar), Heterorhabditis indica (Poinar)and Heterorhabditis baujardi (Poinar) ( Rhabditida : Heterorhabdilidae) and one imported Steinernematid species, Steinernema abbasi (Elawad) (Rhabditida: Steinernematidea) were evaluated against preadult of the citrus mealybug Planococcus citri (Risso) (Hemiptera: Pseudococcidae)and adult of Egyptian mealybug Icerya aegyptiaca (Douglas) (Hemiptera: Monophlebidae)under laboratory conditions. Also, laboratory and semifield evaluation of the efficiency of entomopathogenic nematodes (EPN) alone or mixed with wax remover Oleyl-polypeptide, against adults and nymphs ofthe mealybug Ferrisia virgata (Cockerell) (Hemiptera: Pseudococcidae)were carried out. Nematode reproduction in their cadavers were detected. Moreover, the effect of Steinernema carpocapsae alone or with medical additive (Docusate Sodium) comparing with Super Misrona oil were studied on the grape mealybug, Planococcus ficus (Signoret). Three methods of formulation of Egyptian entomopathogenic nematodes were tested for their effectiveness on H. bacteriophora and S. carpocapsae. These formulations are water-dispersible granules (WDG), Calcium alginate geland infected cadavers. The infectivity of the formulated nematodes was tested against I. aegyptiaca adults.

Predaceous mites (Acari) associated with scale insects (Hemiptera) on fruit trees
Fawzy
H.
Due to the importance of predaceous mites, this work was carried out to survey Raphigmathoid mite species inhabiting fruit trees and debris and associating with scale insects in different localities of Delta and Middle Egypt. In addition, the biology, prey range and its effect on feeding capacity and fecundity of the two prevalent species Eupalopsellus olearius Zaher and Gomaa and Saniosulus nudus Summers (Eupalopsellidae: Acari) were studied. This however might throw light on their role in biological control of associated scale insects.

Modern Biotechnology Tools: A new paradigm for insect research field
Moussa
M.
Biotechnology is a field of applied biology that includes the use of living organisms and bioprocesses in agriculture, engineering, medicine and many other fields demand novel bioproducts. The development of DNA-based techniques, generally known as biotechnology. In early of 1990 and in agriculture field, biotechnology is obviously fitting the broad definition of "using a biotechnological system to make newly and novel products. The genetic modified plant is one of the most renowned examples in agriculture field which created by transferring a desirable gene in plant genomic in order to produce desirable protein (s) that governors specific function in the plant system. For decades, scientists have used traditional breeding to improve the production and crop quality in order to use them for food consumption. In this type of breeding, organisms with desirable traits are mated to produce individuals carry the same traits.Many other applications of biotechnology have been reported in various fields viz, organisms and organism by-products that used to fertilize and restore nitrogen in soil. In insect research field, the biotechnological tools have been applied to study various issues such insect identification, insect control and insect genetic relationships. Bt Cry1Ac modified cotton plant (Bollgard I) was the primary example to control American bollworm; Helicoverpa armigera pest. Thus, exploiting such technology in the field of Entomology could help scientists in understanding various physiological mechanisms occurred in insect.
