The study was conducted to identify of rodent species and their distribution between the old agricultural and the newly reclaimed lands at The farms of the Faculty of Agriculture, Sohag University during 2018/2019.The results showed that there are three field rats, Rattus rattus frugivorus, Rattus rattus alexandrinus, Arvicanthus niloticus a high-density rodents in the old lands to increase vegetation and food preferred in crops to attract rodents on feed and reproduce, While, in the newly cultivated lands found four rodents, three field rats Rattus r. frugivorus, Rattus r. alexandrinus, A. niloticus and one desert rat, Gerbillus gerbillus as low-density may be due to several factors, for example decrease food, the vegetation cover, difficult weather, reproduction decreased, specific competition on feeding. Also, It was also noted that the agricultural rodents occupied the desert lands for the aforementioned reasons and to change the desert ecosystem.

The Impact of Faba Bean Seeds Soaking in Salicylic Acid, Acetyl-Salicylic Acid and Methyl Salicylate on Inducing Plant Resistance against the Cowpea Aphid, Aphis craccivora Koch.
E.
El-Solimany
The present work was conducted in the laboratory of Plant protection, Shandweel Agricultural Research Station, Sohag Governorate to investigate the effect of priming of faba bean seeds with three concentrations, 50, 100 and 200ppm for each substances of salicylic acid, acetyl salicylic acid and methyl salicylate on survival, duration and wing formation of the cowpea aphid, Aphis craccivora Koch., also, their repellent effect was determined. Results obtained showed that the highest effect was recorded in salicylic acid at 200ppm (86.96%) after 24 hours, however, no repellent effects were recorded from acetyl-salicylic acid. Priming faba bean seeds with salicylic acid and methyl salicylate elongated the nymphal stage, decreased their survival and increased wing formation compared to control. The effects of the three substances were found to be concentrated dependant. The use of salicylic acid and methyl salicylate as resistance inducers hold great promise for application for A. craccivora control as eco-friendly method.

Biological Activity of some Synthetic Cyanoacetamide Derivatives against some Cotton Pests
R.

Abdullah
The continuous searching for new compounds that more effective is very important in the pest control field. That is because of the resistance in many pests to several pesticides. In the search for new biologically active compounds, extensive research is based on the synthesis of heterocyclic molecules. In this work, three new cyanoacetamide derivatives were synthesized and confirmed by IR spectra, mass spectra and elemental analysis. These compounds were; (1): 2-cyano-N-(2-hydroxyphenyl) acetamide, (2): (E)-2-cyano-N-(2-hydroxyphenyl)-3-(methylthio)-3-(phenylamino) acrylamide and (3): 1-(2-hydroxyphenyl)-4,6-dimethyl-2-oxo-1,2-dihydropyridine-3-carbonitrile. They were tested as active ingredients against the 3rd instar larvae of cotton leafworm Spodoptera littoralis (Boisd) and the adult stage of cotton mealybug Phenacoccus solenopsis under laboratory conditions. Based on the mortality percentages and LC50 values, all compounds had high toxicity against Phenacoccus solenopsis after 48 hours of treatment. While the second compound was more toxic against Spodoptera littoralis compared with other both compounds that had a very low toxicity.

The peach fruit fly, Bactrocera zonata Saunders (Diptera: Tephritidae) is a very deleterious insect pest for fruits of many horticultural hosts. Boric acid had tested as a safe and friendly-environmental insecticide againstthe pest as baits for adults. Five formulations of baits (water, sugar solution at 5 and 10 % as well as Buminal solutions at 2.5 and 5 %) were applied at 4 concentrations of boric acid (0.5, 1, 1.5 and 2 %)for the newly emerged, 24 hrs old starved flies and 48 hrs old starved flies. The mortality percentages were recorded after 24 hrs and 48 hrs of application. The mortality percentages significantly ranged between 30- 90.67 for the newly emerged flies after 24 hrs and 34.67- 100 after 48 hrs. Also, the ranges of mortality for 24 hrs starved flies significantly were 42.33- 88.67 % after 24 hrs and 55- 100 % after 48 hrs, whereas that recorded for 48 starved flies significantly were 70.33- 93.67 % after 24 hrs and insignificantly 96- 100 % after 48 hrs. Also, results revealed that the mortality percentages increased with the increase of boric acid concentrations, exposure period of application and starvation duration. According to these results, it is recommended to use boric acid in control of peach fruit fly as effective partial bait or mass trapping techniques that ensure no direct contact with the plants.

The entomopthogenic bacterium , Pseudomonas fluorescens, was used alone as soil treatment and foliar application or mixed with entomopthogenic fungus , Beauveria bassiana for controlling the two spotted spider mite ,Tetranychusurticae infesting Cucumberplants comparing with a standard synthetic acaricide ortus . P. fluorescens great effect as soil treatment and foliar spraying, recording reduction percentage of 75.21%. and no significant differences (df =6; P =<0.01) with the reduction caused by the acaricide used and this shows the importance of the role of biopesticides in reducing the population of T. urticae infesting CucumberPlants . There was significant effect on the lipase activities by all treatments, while the activity of chitinase shows that its activity increased at a high rate in all the treatments except ortus treatment compared with control. The acaricide, ortus had strong effect on the activity of acetylcholinesterase (AchE) where the activity of this enzyme decreased significantly (df =5; P =<0.01) to the extent of inhibition. While, the activity of this enzyme increased in the other treatments, where the activity reached nearly the control . The treatments which caused high reduction percentage gave high yield amount. There were nonsignificant differences in yield amount in treatment with (ortus), and (soil and foliar application of P. fluorescens), that indicates the important role of P. fluorescens in IPM against mite.

Interference Effect of Two Entomopathogenic Organisms against Cowpea Aphid, Aphis craccivora Koch.
M.
Imam
The Cowpea aphid, Aphis craccivora Kock, is a common pest of several important ornamental plants.This work aims to investigate the toxic effect ofBacillus thuringiensis and Beauveria bassiana isolate on 2-3 days old adult A. craccivora,the effect of the bioinsecticide was strong on adult individuals. On the other hand the calculated LC50 values on newly emerged adults of aphid were 6.31 CFU/ml and 73868X106 spores/ml, respectively. This study has shown that, the fungus has a more effective than bacteria on adult aphids.
