laboratory or greenhouse conditions. With respect to laboratory test, results of the
four concentration tested of Aloe vera products i.e. 1:5, 1:10, 1:50 and 1:180ml at
20s1°C and 30i1°C against Mincognlta (J2) showed that all concentration were

same plant products at the best concentration 1:5 and 1:10 on Mincognlfa infecting
banana plant under greenhouse, results indicated that root gall index and rate of
nematode reproduction were decreased, especially in their application after
nematode inoculation, followed by those before nematode inoculation. obviously
oxamyl 24% indicated gave the best effect on nematode reduction when compared
with treatments of Aloe vere plant products tested.https://jppp.journals.ekb.eg/article_235192_8a2e0e363e3ecb8214f55a480fe6f856.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-367731420060401SUSCEPTIBILITY OF FOUR SOYBEAN VARIETIES TO INFESTATION WITH SOME SUCKING PESTS AND COTTON LEAFWORM AND THE EFFECT OF MAIN WEATHER FACTORS ON INFESTATION2369238523519410.21608/jppp.2006.235194ENRoud A.El-Doksh,Plant Protection.

The results obtained revealed the following indications.
1.There were significant differences between the four soybean varieties in case of
whitefly (adult and immature) population in two growing seasons and the highest
mean numbers of white fly were recorded with Giza 21 and Giza 111 varieties in
two seasons.
2. One peak was recorded with all soybean varieties in the two growing seasons in
case of cotton leafworm (larvae) and the highest number was recorded on Giza 22
variety.
3. There were significant differences among all soybean varieties (G. 21, G. 22, G. 35,
and G. 111) in case of Aphis gossypr'r‘ in two seasons and the highest mean number
of aphids was 341.79 insects“ 00 plant/week with Giza 35.
4. The population of jassids on soybean was considerably low during the two ses..cr.s
and the pest started to appear on soybean during June and reached its maximum
during the 1“ of September.
5. in case of Tetranychus urticae, significant differences were recorded among all
soybean varieties in the two seasons and the highest mean numbers were 305.43

6. The effect of the prevailing weather factors (Max. and Min. temperatures, relative
humidity and wind speed on the infestation degree of soybean varieties with these
insects revealed that there were insignificant correlation values except some factors
on some soybean varieties.https://jppp.journals.ekb.eg/article_235194_c324d664b467b04bb9ba4b5a0ff142c2.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-367731420060401PREVALENCE OF BORRELIAL INFECTIONS IN TICK VECTORS AND VERTEBRATE HOSTS IN ESMAIELIYA GOVERNORATE, EGYPT.2387340323519810.21608/jppp.2006.235198ENS.

governorate for 2 successive years from Mar. 2000 to Feb. 2002. The borrelial
infection rate occurred in the tick population throughout the year. Spirochetes were
detected in 3?.28% of the 1870 ticks examined. The highest percentage (p < 0.001),
of infection with Borreiia Sp. in ticks were recorded in H. dromedarii (47.92%), followed
by R. sanguineus (38.37%), B. annuiatus (32.5%), and H. excavatum (30.42%). The
prevalence of infection rate with Borreiia Sp. in the females of each species was
higher than males. The highest levels of infection with Borreiia in adult ticks were
recorded in summer. Boneiia spirochete was detected in 35.79% of the blood
samples (1900 samples) which were collected from man in Esmaieliya. governorate.
Where, the maximum infection rates were recorded in July. The highest infection rate
in blood smears which were collected from animals in Esmaieliya was recorded in
camels (23.45%), followed by dogs (13.27%), goats 8. sheep (12.15%), cattle and
buffaloes (10%). The changes in prevalence of Borrelia infection rate in the tick
population were positively correlated with changes in antibody prevalence in man and
animal hosts and with changes in the tick population density. Generally, the all studied

Sulpher gave high initial reduction, where it exhibited 88.2 and 69.2 98 respectively.

Also, the effect of both pesticides on whitefly (mature and immature stages)
were moderate to weak effect.
As for their side effect on the associated natural predators, Marshal induced
moderate effect while Sulphur exhibited a slight effect against (true spider, Chrysopa

Uriomyza trifolii (Burgess) were investigated throughout the growing season of broad

2002 seasons. Traps were positioned at five different heights above the ground; 25,
50, 75, 100 and 125 cm. The yellow sticky trap was an effective tool for monitoring the
adults of L. trifalii. Yellow traps placed 25 cm above the ground caught significantly
more adults than the other trap heights overall the growing season. Thus, this leaf
miner has a limited vertical range of flight activity. The correlation between trap < /p>
heights and the number of adults trapped was negative. The males and females were
equally responsive to yellow traps at any height. in both seasons, the highest number
of seized aduits occurred in February and March, while, the lowest adult populations

Experimental Station, in the Western region of Saudi Arabia to evaluate the effect of
soil solarization, by mulching the soil with transparent polyethylene sheets in
combination with three different green manure amendments by adding cabbage,
conocaes or neem leaves to soil prior to solarization on population densities of soil
fungi, weed growth and yield of two varieties of zucchini plants. The total number of
soil fungi was declined by 63% immediately after solarization then increased at the
end of the first and second season to 80% of the initial pre~solarization soil samples.
Soil amendment with conocarpus, neem or cabbage decreased the populations of soil
fungi by 40.1, 30.9 and 30.3%, respectively. Weed growth was declined by 92.5% in
solarized soils, and to a less extent by manure amendment that ranges from 26-40%
reduction. Yield of zucchini plants was increased by 13.4% in solarized soils as
compared to non—solarized soils. Amendment with green manure alone, however,
increased yield by 14.5-19.B%. More yield of zucchini plants and more control of
weeds was obtained in solarized amended soils than in solarized or amended soils

Center, Dokki, Giza, EgyptJournal Article20060319Several hundred pesticides of different chemical nature are currently used in
large quantities especially in developing countries for the control of agricultural
pests. Because of their widespread use, they are detected in various environmental
matrices, such as soil, water, and air. The aim of this study is to determine aspects of
sediment quality in different sites along the River Nile, by analyzing their content of
organochlorine and organophosphorus pesticides residues. Surface samples from 27
sites were collected from different locations of River-.Nile from Aswan to Damietta
Governorate during December 2004 to January 2005. The obtained results detected
that thirty-two different pesticide residues were monitored in sediment samples and
most of the analyzed sediment samples contained detectable levels of pesticide
residues, according to sampling location. Organochlorine pesticides were the main
contaminations of sediment samples, while the existences of organophosphorous
pesticide were the negligible in the same selected sites. BHC isomers i.e., c1, [3, y, 6;
cyclodine i.e., heptachlor, heptachlor epoxide, y-chlordane, aldrin, dildrin, endrin and
diphenyl trichloro ethan i.e., p, p-DDE, o, p -DDT, p, p-DDD and p, p—DDT were
detected at significantly greater concentrations than other pesticides. The geographic
distribution of pesticide concentration generally follows regional patterns in
agricultural use and the influence of urban area. Upper Egypt Governorates recorded
higher concentration of organochlorine pesticide residues than North Egypt
Governorates; on the other hand, North Egypt Governorates recorded high
concentration of organophosphorous pesticide residues than detected in Upper
Egypt Governorates. In general, it was found that the detected amounts of
organochlorine pesticide residues always same residue content in sediments from
other rivers in the world. However, the detected content of pesticide residues in the
studied sediments are in the permissible limits.https://jppp.journals.ekb.eg/article_235213_3be56074ff080405394a878e53742811.pdf
