In the apiary of Assiut University, the oriental hornets, Vespa orientalis L., were trapped and collecting every three days by using modified wooden traps to know their fluctuation and population during their active season. Also, detect the differences on the morphology, ultra-structure, and behavior between the different casts (queen, daughter worker and male) of V. orientalis. In the present study, the fluctuation showed that hornet population began with a slight increase number during September which comprised about (12.3%). In October, a big jump occurred (52.5 %) in their number. By the first week of November, the number started to decrease (26.7%) and then disappeared at the second fortnight of November. Antenna plays an important and vital role during host finding and acceptance behavior in insect life. Like many insects, oriental hornet Vespa orientalis L., use antennal chemo-receptors to detect the hosts during its active seasons. Scanning electron microscope (SEM) studies showed five types of sensilla (Chaetica, trichoidea, basiconica, placodea and coeloconica) were distributed on the antenna of the three different casts of the hornet. These function of sensillae possibly as chemo-, and tactile receptors, responding to movements of the antennae.

Antennal sensillae of male and female peach fruit flies, Bactrocera zonata (Saunders) (Diptera: Tephritidae), obtained from three different host fruit species (guava, Psidium guajava L. (Myrtales: Myrtaceae); peach, Prunus persica (L.) Stokes (Rosales: Rosaceae); and orange, Citrus sinensis (L.) Osbeck (Sapindales: Rutaceae)), were studied with scanning electron microscopy. This study was carried out to describe the different types of sensillae present on the three antennal segments (scape, pedicel, and flagellum or funiculus) of both sexes of B. zonata on different host fruit. The antennal segments of females tended to be larger than those of males feeding on peach and guava fruit. On orange, both sexes were similar (no significant differences were found). The first two antennal segments, scape and pedicel, are reinforced by some bristles and have different types of sensillae, including trichoid I, II, S; basiconic II; and sensilla chaetica in different numbers on different host fruit species. Numerous microtrichia, as well as trichoid (I, II), basiconic (I), clavate, and coeloconic (I, II) sensillae were observed on the funiculus with a great variation in number and length. As a result of feeding on different hosts, differences were found between sexes and some plasticity in size, number, distribution, and position of some sensillae, including trichoid, basiconic, chaetica, and clavate on the antennae of the female B. zonata. These sensillae were significantly larger in females. Also, some morphological and morphemetric differences have been found according to their feeding on different host fruit.

Magnetic susceptibility (MS) measurements of marine rocks provide an underutilized but powerful high-resolution tool in stratigraphy. In ideal circumstances and when combined with other stratigraphic techniques, the method can yield resolution to 10,000 years or less. This paper applies the MS method to solving a Cretaceous global correlation problem. Because of the active global processes that drove significant evolutionary changes during this time, the Upper Cretaceous is important in Earth history. However, correlations among geological sequences are difficult, in part because Earth’s magnetic polarity was essentially non-varying from the Aptian to the Santonian. Here we present high-resolution correlations for Upper Cretaceous marine sedimentary successions spanning all or part of the Santonian Stage from the Western Interior Seaway (U.S.A.) and the Western Sinai Peninsula (Egypt). To do this we have integrated the results of magnetic susceptibility (MS) measurements of unoriented samples from lithified marine rocks (in outcrop and from core) and biostratigraphic data sets from these sequences. In this study a MS zonation for the Santonian Stage has been developed and graphic comparison has been used for correlation. In the main, correlation between the U.S. and Egyptian sequences is excellent. Third order T/ R cycles (> 100 ka) observed in this high-resolution data set for the Santonian Stage indicate significant similarities between the U.S. and Egyptian sections and allow correlation among sequences. We interpret these correlations to result from cyclicities caused by climatecontrolled continental erosion and deposition of detrital components, mainly clay, in the marine realm. Second-order cycles (> 1 Myr), are also observed in these data sets but show distinctive differences between the U.S. and Egyptian sequences. We interpret these second-order differences to result from local synsedimentary tectonic controls on sediment erosion and deposition. Also observed are two distinct, shortterm MS marker events that can be correlated globally.

A field study was carried out on the population dynamics of the Mediterranean fruit fly (MFF) Ceratitis capitata Wied. males in Assuit governorates (upper Egypt) during 2011/2012 and 2012/2013 seasons in mixed orchards by using Jakson trap. The obtained data revealed that the occurrence of MFF was relatively all over the two seasons with some exceptions. The abundance of the pest was higher in the second season than that in the first one. The higher appearance of the pest was recorded on September-November in both first and second seasons. Temperature had significant negative correlation (r=-0.105) in the first season and insignificant negative correlation (r=-0.076) in the first and second seasons, respectively. However, R.H.% had high significant positive (r=0.451) and insignificant positive (r=0.203) in the first and second seasons, respectively. Results obtained could be exploited in management of this insect pest especially, in the control programs.

The objective of traditional goal-oriented strategies is to construct an optimal mesh that mini-mizes the problem size needed to achieve a user prescribed tolerance error for a given quantity of interest (QoI). Typical geophysical resistivity measurement acquisition systems can easily record electromagnetic (EM) fields. However, depending upon the application, EM fields are sometimes loosely related to the quantity that is to be inverted (conductivity or resistivity), and therefore they become inadequate for inversion.

A Bayesian inversion methodology for identification of large-scale subsurface structures (strata) from controlled source electromagnetic data is developed. The Bayesian inverse problem is solved by sampling from the posterior probability distribution, using the ensemble Kalman filter. Prior knowledge is incorporated in the methodology by utilizing structural prior information from, for example, interpreted seismic data. A model-based, composite parametrization of the electric conductivity distribution is applied to represent
