The present study was conducted during two successive seasons in the period from 2011 to 2012 to survey some aphids species <em>Rhopalosiphum maidis </em>(Fitch)., <em>Rhopalosiphum padi</em> (Linnaeus)., <em>Aphis gossypii </em>(Glover). , leafhoppers species<em> Empoasca decipiens </em>(Paoli), <em>Empoasca decedens </em>(Paoli) , <em>Cicadulina chinai</em> (Ghaui) , <em>Balclutha hortensis</em> (Lindb) and <em>Cicadulina bipunctella zeae </em>(China), planthoppers species namely <em>Sogatelle vibix </em>(Haupt) and<em> S. furcifera</em> (Horv.) and two stem borers<em>Sesamia</em><em> cretica</em> Led,<em> Ostrinia</em><em> nubilalis</em> Hun infesting maize plants and their associated predators.The ecto-larval parasitoid species, <em>Bracon brevicornis </em>Wesm . was reared in the laboratory on full grown larval of the corn borer, <em>S.</em><em> cretica </em>Led. Some biological aspects of parasitoid were studied. Total developmental period of immature stages (egg – adult) lasted 16.05 days. Average number of deposited eggs / female was 209.08 eggs. Mean number of eggs deposited per host larva was 8.19 eggs. Sex ratio (male: female) was 1 : 0.54 when the parasitoid was reared on <em>S. cretica </em>grown larvae . The results indicated that increase of the parasitoid density, increased the number of host larva parasitized, fecundity and total progeny, while the sex ratio (female %) was decreased. Adult longevity was affected by temperature and food supplied. Four predators were associated with these insects on maize. These predators were <em>Coccinella undecimpunctata , Metasyrphus Corollae </em> , <em> </em><em>Chrysoperala carnea </em> and true spiders

Under greenhouse conditions, the tested materials i.e. plant water seeds extract solutions have significantly reduced and affected number of galls and eggmasses of<em> Meloidogyne incognita </em> on roots and its number of J<sub>2 </sub>in soilof tomato, <em>Lycopersicon esculentum</em> Mill cv. Castle Rock compared to untreated control . Isothiocyantes components from seeds of <em>Sinapis alba, Ammi visnaga, and Lepidium sativum</em> using its biofumigation separately on the degree of nematode reduction parameters varied according to the concentration and type of the tested materials. Significant increase in weight of fruits / plant was also achieved by most tested materials. These results suggested that species of Apiaceae plants may be used in crop rotations as antagonistic plants or green manures to reduce <em>Meloidogyne</em> galls and eggs on rot systems. Dry preparations of these tested plants or extracts could be used as bionematicides.

A survey conducted recently in Sharkia governorate, Egypt indicated the presences of 11 species of predatory mites on grapevines. These species belong to families Phytoseiidae (8 species), Cunaxidae (one species), Cheyletidae (one species), Stigmaeidae (one species). Frequency occurrence of the collected species was discussed. A logistic regression of the proportion of prey consumed as a function of initial prey density was conducted to identify functional response types. Nonlinear least-squares regression and the random predator equation were used to estimate attack rates and handling times . Overall, adult females <em>E. metwallyi</em> exhibited a type 2 functional response to <em>T. urticae</em>. Whereas, attack rate and handling time of <em>E. metwallyi</em> recorded 0.10 , 0.28 and 0.07 and 0.99 , 1.47 and 4.59 when offering eggs , males , females of <em>T. urticae, </em>respectively. Generally, these results indicated that the predator <em>E. metwallyi</em> may be considered as biocontrol agent against the two-spotted spider <em>T. urticae</em>.

The efficacy of five insecticides [organophosphate (methamidophos), carbamate (methomyl), pyrethroid (Deltamethrin), spinosad (spintor) and imidaclopride (Confidor)] were determined against four strains of <em>Tuta absoluta </em>collected from four governorates in Egypt [Damytta (DAM), Marsa Matrouh (MAR), Behera (BEH) and Kafer El-Sheikh (KAF)]. Collected strains were bioassayed and compared with a reference susceptible strain. Insecticides were dissolved in acetone and topically applied to the mid-dorsal abdominal region of two-day old 4th instar larvae. LD50 values were estimated and the Resistance Factor (RF) for each insecticide was calculated (RF = LD50 value of each field strain / LD50 value of the susceptible strain). DAM and MAR strains recorded 29.72 and 10.62-fold resistance, respectively to methamidophos. DAM and MAR strains recorded 32.53 and 10.76-fold resistance, respectively to methomyl. DAM and MAR strains demonstrating 70.81 and 28.09-fold resistance, respectively to deltamethrin. DAM and MAR strains recorded 38.04 and 17.08-fold resistance, respectively to spinosad, while KAF and BEH strains demonstrated 14.92 and 12.14-fold resistance, respectively to confidor. These results are discussed in relation to the possible mechanisms of resistance present in the studied <em>T. absoluta </em>strains and underpin the resistance management strategy for the tomato borer in Egypt.

The effect of the feeding of the mango rust mite <em>Metaculus</em> <em>mangiferae</em> (Attiah) (Acari: Eriophyidae) on the mineral content of mango leaves <em>Mangiferae indica</em> L.(Anacardiaceae) was studied. The research was carried out on two mango cultivars: Langra and Ewesi as host plants. Nutrients were estimated in fresh plant material in control (healthy leaves ) and lightly and highly infested leaves of each tested cultivar. The highest concentration of minerals was noticed in the healthy leaves. No significant differences were found in most total level of macro and micro nutrient contents between lightly infested and healthy leaves of both cultivars. The high decrease of all minerals was recorded in the injured Ewesi leaves followed by Langra when compared with the fresh material. The mango rust mite <em>M. mangiferae</em> had the strongest influence on the macro- and micronutrients of its host plants <em>M. indica.</em>

Morphological characteristics of authentic cultures of <em>Pestalotiopsis</em> isolates using scanning electron microscop (SEM) revealed that, no presence of pycnidia for all examined <em>Pestalotiopsis</em> isolates, that produced acervuli only . Acervuli size ranged between 350 – 800 μ in length to 270 – 500 μ in width. Isolates varied in its ability to utilize different carbon sources. There were significant differences in the growth of <em>Pestalotiopsis</em>isolates in different carbon sources containing medium. Maltose gave maximum mean dry weight of mycelial growth. Ammonium nitrate recorded the maximum growth of <em>Pestalotiopsis isolates </em>as the nitrogen source, followed by potassium nitrate. On the other hand, the minimum mycelia dry weight of the fungus was in Aspartic acid containing media. Sporulation was dense where sodium nitrate was used as the nitrogen source, and deprived when asparagine was used. The genetic variation between fifteen isolates of<em>Pestalotiopsis</em> spp. were studied using four ITS primers (1&2, 4&5) ) and SSR 1,2,4,5 and protein electrophoresis.
