An experiment was conducted in a field at Beni Suif Governorate to estimate the effect of intercropping of garlic plants on the population of different pests, mites, Tetranychus urticae, Thrips, Thrips tabaci and tomato leaf miner, Tuta absoluta with tomato plants during the cultivated seasons, 2014 and 2015. The obtained results indicated that the populations of the two spotted spider mite, thrips and T. absoluta recorded 144.3, 111.3, 222.4 with an average of 16.03, 12.37 and 24.71 individuals in case of tomato solely, during 2014 season, respectively, which changed to 630, 420 and 77.7 with an average number of 70, 46.67 and 8.63 individuals of the same pests in case of tomato plants intercropped with garlic, respectively in the same year. On the other hand, the population of the collected pests were 199.6, 77.4 and 261.3 individuals during 2015 season for tomato plants without intercropping with an average of 22.178, 8.6 and 29.03 individuals, respectively, while in case of intercropping system, these numbers were 498.4, 271 and 69.6 with an average of 55.378, 30.11 and 7.73 individuals, respectively when the tomato plants intercropped with garlic plants. The results showed that the correlation was positively between the factors on the population of different pests in case of tomato plants only and in case of application of intercropping method with garlic plants.

Spiders are among the most abundant predators recorded on date palm trees in Beni-Suif and Qaluobia Governorates. They are voracious predators, and combined with their high abundance, which play an important role in the reduction of different pests' populations. Field trials were conducted in QaluobiaandBeni–SuifGovernorates during the period of October 2013 to October 2014 to show he incidence of different spiders. Obtained data recorded that the collected predaceous spiders were identified into 14 families in Beni-Suif included 11 families recorded in Qaluobia as follows; Theridiidae, Philodromidae, Thomisidae, Lycosidae, Linyphiidae, Gnaphosidae, Dictynidae, Miturgidae, Araneidae, Tetragnathidae, Agelemidae, Scytodidae, Filistadae and Uloboridae. Also a ratios of these count, indicated that an average of 25 % of spider families and spices were absent from palm in Beni–Suif Governorate. On the other hand, under these families recorded 19 species of predator. The most numerous spiders species collected from date palm phoenix dactylifera at Beni–Suif Governorate were 227 individuals of Steatoda pykuliama, while the high number of predators species collected from Qaluobia Governorate were 223 individuals of Filistata hibernalis.

The Mediterranean flour moth, Ephestia kuehniella (Lepidoptera: Pyrallidae) is one of the most destructive pests of flour, grains, baked goods and cereal products. The morphology of the larval antennae and mouthparts is described and illustrated with the aid of scanning electron microscopy, with particular focus on the sensilla. The antennae possess three types of sensilla: two sensilla chaetica, six sensilla basiconica, and a sensillum styloconicum. The labrum bears six pairs of sensilla chaetica. Each dentate mandible carries two sensilla chaetica on outer surface and five teeth.On the maxilla, both cardo and stipes carry one sensillum chaeticum. Each galea has three short-sharp sensilla basiconica, two large sensilla styloconica and three sensilla chaetica. The distal segment of the maxillary palp possesses seven sensilla basiconica, and one sensillun styloconicum. Each labial palp bears distally a cone-shaped sensillum chaeticum and an elongate sensillum styloconicum. In addition, the functions of these sensilla are discussed by comparing them with those of other Lepidopteran larvae.

An experiment was carried out to study the effect of planting space, some weather factors and plant age on the population density of Leaf miner, Liriomyza trifolii (Burgess) infesting pea plants in Plant Protection Research Station in Kaha region during two successive seasons 2013 and 2014.
The obtained results revealed that the population density of L. trifolii larvae on pea plants differed significantly according to the planting spaces (10cm, 20cm and 30cm) during the two studied seasons. Planting of pea seeds in the planting space (10cm) lead to plants suffered from the highest infestation by L. trifolii. Larvae (30.7 and 34.1 larvae/ 15 leaves during the two seasons, respectively. On the contrary, sowing the pea plants at the second and third spaces (20 & 30cm) can be reduced the infestation rate of this insect pest (4.97 & 3.2 larvae/ 15 leaves) and (5.16 & 2.6 larvae/ 15 leaves) during the two seasons, respectively.
The population density of leaf miner, L. trifolii increased by increasing the plant age until middle of the flowering stage. The lightest population was recorded during the fruiting stage. While, the pea plants infested by the heaviest population during vegetative and flowering and stages.
Statistical analysis of correlation coefficient and partial regression values showed that the effect of weather factors and plant age on the population density of L. trifolii was differed to positive or negative correlation according to planting spaces and plant stages (vegetative, flowering and fruiting stages) during two studied seasons.
The weather factors were more effective on leaf miner population when comparing with plant age, the explained variance (E.V. %) were 74.4, 66.4 and 72.3% for the three planting spaces in the first season and 18.5, 29.3 and 40.4% in the second season, respectively. While the combined effect of the plant stages (vegetative, flowering and fruiting stages) together on L. trifolii population in the tested planting spaces on pea plants were 38.5, 21.1 and 15.7 at the three planting spaces during 2013 season and 27, 10.2 and 6.3 % during 2014 season, respectively.

Cotton mealybug, Phenacoccus solenopsis Tinsley was recorded as a new pest for the first time attacking three important vegetable crops and another important field crop in Egypt, especially at Fayoum Governorate in two districts. P. solenopsis was recorded on tomato, eggplant, pepper and maize during growing summer plantation 2016 from July till September, at Fayoum Governorate, in Egypt. Specimens of insect mealybug pests were collected from the four crops from two locations (Fayoum and Itsa didricts). The mealybug was identified as P. solenopsis according to taxonomic key of this genus and species in the Scale insects and Mealybugs Department, Plant Protection Research Institute, PPRI, ARC. .
Population density of P. solenopsis was done during field work season. Results of density showed that tomato plants infected with a high numbers P. solenopsis by mean 15.3 and 15.4 individuals/ plant and has one peak in the first week of August by mean 35 and 39 individuals/plant, for Fayoum and Itsa districts, respectively. But the other two crops such as, eggplant and pepper infected with a few numbers of this pest by mean (5.2 & 7.8 individuals/ plant) and (4.5 & 6.5 individuals/ plant) for the first and second crop, for Fayoum and Itsa districts, respectively. There was one peak in the second week of August by mean (15 & 20 individuals/ plant) for eggplant and (14 &15 individuals/ plant) for pepper, for Fayoum and Itsa districts, respectively. While in maize a very few numbers occurred it by mean (1.4 & 2.8) individuals/plant, and has one peak during the second week of August, being (5 & 8 individuals/ plant), for Fayoum and Itsa districts, respectively. Statistical analysis of data showed that, there were highly significant differences between the two locations cultivated by tomato crop, but no significant between the same location cultivated by eggplant and pepper crops. On other hand, there was a significant difference between the two locations cultivated by maize crop and significant differences between (eggplant+ pepper) and maize. This study was represented the first record of P. solenopsis as a new pest attacking three important vegetable crops and another important field crop in Egypt, especially at Fayoum Governorate

Several thrips species are known to feed on soybean (Glycine max Merr.) and can cause yield reduction. Beside, the other important reason for thrips survey is to determine its role as vectors of Tospovirus in soybean. There is little information available about thrips species present on soybean crop, and their abundance in Egypt. Field survey took place at the farm of Agricultural Experiment Station, Faculty of Agriculture, Cairo University, Giza Governorate, Egypt (season 2014) to survey the different thrips species. Soybean cv. Giza 111 was sown in late May. The experimental area received all the usual agricultural practices except for any pest control measures. Thrips species associated with soybean were collected and differentiated to species. A total of 16 different thrips species was surveyed. These included 14 phytophagous and 2 predator thrips species. The most abundant species was Thrips tabaci with an average No. 226.2individual/plant, it had two major peaks on soybean, the first peak was at late June (21.9 individual/ plant), while the second one was occurred on mid-August (38 individual/plant). Frankliniella occidentalis occupied the second rank (107.02 individual/plant, Neohydatothrips variabilis came third in that order (57.5 individual/plant) followed by, Caliothrips phaseoli, F. tritici and F. Schultzei ( 42.1 & 43.2, 56.5individual/plant respectively). N. variabilis, Caliothrips phaseoli and F. schultzei werereached their highest numbers (13.2, 19.4 & 16.3 individual/plant) by the end of the season, respectively.Generally speaking, both soybean thrips, N. variabilis and bean thrips, Caliothrips phaseoli, were recorded for the first time in the present study. Characterization and identification of both two species are presented. There were 27 weed plant species collected from soybean field. Both of T. tabaci and F. occidentalis were the most common species of soybeanand associated weeds.The highest average No. of thrips species was recorded on Ammi majus L. (70.7 individual/plant) followed by Medicago intertexta L.,Convolvulus arvensis L., Melilotus indicus L., and Malva parviflora L., which harboured (52.3, 48.8, 44.3 & 44.5 individual/plant, respectively), while the lowest average no. (3.3 individual/plant) was occurred on Urtica urens L. Seasonal abundance of the thrips species associated with weeds, proved that both T. tabaci and F. occidentalis were the most dominant species (36.7 & 17.4 individual/ weed plant, respectively). In conclusion, weeds can serve as reservoir alternative hosts for plant viruses and thrips vectors, therefore should be considered when endeavoring to manage and control plant viruses of cultivated soybean plants.

The two investigated plants, sweet marjoram (Origanum majorana L.) and sweet basil (Ocimum basilicmum L.) plants are considered the most important medicinal and aromatic plants. They are infested with many mites specially, the Tetranychus urticae Koch during growing season which cause considerable damage in the crop under Egyptian conditions. The present study was conducted during 2014 & 2015 seasons for sweet marjoram and sweet basil plant species at Giza governorate to survey the mite infesting these two crops at both governorates, the population fluctuations of the most important key mite and their relation to the a biotic factors (Mean temperatures & mean relative humidity as well as their associated predator, Neoseiulus californicus as biotic factor. Survey of mite species T, urticae (larvae, nymphs & adults) and predator species were recorded onsweet marjoram and sweet basil at Giza governorate. These factors gave different correlations with the population activity at Giza governorate and both host plants.
We present the results of a two-year study on the population dynamics of T. urticae, as well as the association between weather parameters and the seasonal population trends of T. urticae. The objective of the present study was to find out the cause of mite outbreaks under the different climate condition and its predator effect as biotic agent.

The phytophagous mites are common pests in agricultural systems, causing in many cases greater economic losses than other any pests.
The population fluctuation of some phytophagous and predaceous mites were determined for two successive seasons, 2014/2015 and 2015/2016 on (eggplant) at Giza, Governorate, and these mite was with relation to some weather factors (maximum, minimum temperature and relative humidity), and the predaceous mites. The population fluctuation of the phytophagous and predaceous mites was not significant positive correlation between both mites and weather temperature (Max. and Min. Temp.) during the two seasons, while for the relative humidity the correlation was negative with the phytophagous and predaceous mites during the two seasons. The predaceous mites, Euseius scutalis, Typhlodromips swirskii and Pronematus ubiquitus were found in relatively few numbers during January and the following months. A highly significant positive correlation was found between Tetranychidae, Eriophyidae and weather temperature (Max. and Min. Temp.). While, significant negative correlation was confirmed between mites infestation and relative humidity. Highly significant negative correlation was occurred between Tarsonemus smithi and weather temperature, while it was a highly positive correlation between mite infestation and relative humidity. The effect of maximum and minimum temperature on the predaceous mites showed significant effective, positive correlation between both the mites and weather temperature, while a negative correlation was confirmed between the predaceous mites infestation and relative humidity on eggplant during the two studied seasons.
