This study was conducted to evaluate the physiological and biochemical changes, [glutamic pyruvic transaminase (GPT), glutamic oxaloacetic transaminase (GOT), total soluble protein (TSP), lipid peroxidation (MDA) and protein carbonyl content (PCC)] in haemolymph of mulberry silkworm <em>Bombyx mori</em> larvae were reared on mulberry leaves treated with camphor honey and oil as a nutritional additives in the 4<sup>th</sup> and 5<sup>th</sup> instars with five concentrations. Results showed that at 4% & 5% concentrations of honey and 1% & 2% concentrations of oil exhibited the best results compared with control; larvae reared on leaves enriched with these concentrations of honey and oil showed a significant increase in GPT, GOT and TSP means and a significant decrease in free radicals (MDA & PCC) means compared with control.

The present study was designed to determine the effect of seven chemicals used to control mange mite on sheep. These chemicals were (1) Mange cides 10%, (2) Tincture idone 4%, (3) Noromectin 1.0% used once a month, (4) Noromectin 1.0% used twice a month, (5) Mange cides + skin recovery, (5) Noromectin 1.0% injection + Mange cides and (7) Mange cides + skin recovery + Noromectin 1.0% treated twice a month.
Sheep infected with scabies were responded to the healing of the disease when treated with the compounds mentioned above (i.e., Mange cide 10%; Tincture idone 4%; Norometcin 1.0% once a month and Noromectin 1.0% twice a month) are just 45, 45, 30, and 20 days, respectively.

The present study was carried out at Rice Research and TrainingCenter farm and Plant Pathology Department, Sakha, Kafr El-Sheikh, Egypt. During 2012 and 2013 successive seasons to screen and evaluate some exotic and local seven verities along with the best 13 selected lines developed from the diallel cross which done during 2006. selection was done from F2 up to F5. Screening testing was made for the 20 rice genotypes against the major diseases infesting rice in Egypt such as, blast, brown spot, bakanae and white tip nematode diseases. Randomized complete block design with three replicates was used under field condition to estimate yield and its attributes as well as the reaction of the different studied diseases. Twenty entries/genotypes were tested under greenhouse and field conditions. Results indicated that, SP- 70, IRAT 112, IR 65610-105-2-5-2-2-2, GZ 7769-2-1-1-2, SK-101-7-16, SK-101-7-17, SK-101-7-25, SK-101-7-26, SK-101-7-35, SK-101-7-37, GG-46-6-1, SK-101-Pa-1, SK-101-Pa-3 and SK-101-Pa-4 were resistant to all rice blast races under this study. On the other hand, GG-24-1-2 and GG-42-2-6 genotypes were susceptible to one race, while GG-24-1-2 showed moderate resistance for the two races. For brown spot results indicted that, HR 4856, IRAT 112, SK-101-Pa-1and Sakha 101 gave the highest infection percent and severity. On the other hand, GG-46-6-1, SK-101-7-26, GG-42-1-2 and SK-101-7-35 gave the lowest infection percent and severity. For bakanae disease, Sakha 101 as a susceptible cultivar gave the highest percentage and severity infection values of 76.08 and 18.66 % respectively, followed by GZ 7769 and Sakha 104 (65.74, 15.33 % and 47.57, 13.15 % respectively). On the other hand, all entries gave the lowest infection of bakanae rice disease under natural infection. For white tip nematode, the genotypes of GZ 7769, HR 4856, Sakha 104, SK-101-Pa-3, Sakha 101 and SK-101-7-26 gave the highest infection. While the genotypes, SP-7, SK-101-7-16, SK-101-7-17, SK-101-7-35, SK-101-7-37, GG-42-6-1, GG-42-1-2, GG-42-1-6 and SK-101-Pa-4 gave the lowest infection values. For Vitavax as recommended fungicide to control rice Bakanae disease and sodium chloride treatment were the highest efficiency to control the bakanae disease under natural and inoculated conditions. Results show that some genotypes could be used i.e. SP-70 and SK 101-7-16 and SK 101-7-17 and SK 101-7-35 and SK 101-7-37 and GG-46-6-1 and GG 42 - 1-2 and GG 42-1-6 and SK 101-Pa-4 as the sources of diseases resistance in rice breeding programs.

The effect of natural conditions on some biological aspects of the parasitoid <em>Trichogramma evanescens</em> (Westwood) was studied when reared on<em> Sitotroga cerealella </em>eggs in the laboratory and attacked both <em>Pectinophora gossypiella</em> (Sound.) and <em>Sitotroga cerealella,</em> (Oliv.) eggs in natural conditions. The study was conducted on three ages of the parasitoid i.e., 3, 5 and 7 day's old after parasitism on temperature degree of 25°C±1 and 75±5%RH. The investigation was carried out by conducting two experiments; the first was under incubated conditions, 25°C±1 and relative humidity 75±5%. The second was under normal weather conditions during June and July2013 in open area in plant protection research institute. Results showed that every age was affected by exposure to natural conditions comparing with incubated one. The total mean percentage of adult emergence decreased from 96.34% in incubated conditions to 93% in natural conditions. The percentage of emergence for the parasitoid of 5 days age did not affect by exposing to natural conditions, as the percentages were insignificantly differed from 95.67 to 94.13 % for incubated and natural conditions, respectively. The age of 3 days old was the most affected age by exposure to natural conditions. General productivity of the parasitoid was higher when attacked <em>P. gossypiella</em> eggs (20.98♀/female) than when attacked <em>S. cerealella</em> eggs (13.90♀/female) in natural conditions.
