Developmental time, consumption rate and fecundity of Cheyletus malaccensis Oudemans were studied on different stages (eggs, immatures and adults) of Tetranychus cucurbitacearum (Sayed)at laboratory conditions, 32±2°C and 50±10% R.H.
Data analysis revealed a significant effect among different stages except for incubation period at both sexes. Life cycle of female was longer than of male. Duration of female was 28.7, 20.4 and 23.4 days and 17.79, 18.15 and 20.9 days for male when fed on the three preys, respectively. The adult longevity of female showed longer duration (52.4 days) when fed on eggs than male (18.9 days) fed on the same prey. The number of prey consumed and the fecundity were significantly lower when fed on T. cucurbitacearum ( immatures and adults) compared to eggs of the same prey.
Data provide fundamental information for understanding the effect of different prey on development of C. malaccensis.

The present study was conducted to evaluate the effect of buprolord as IGR against the two spotted spider mites (TSSM), Tetranychus urticae Koch. Also, the behavioristic action of mixture of buprolord and extract of Ipomoea carnea was included. A positive correlation between concentrations used and mortality percentages was recorded.
The idea was to try to reduce the extravagant of traditional pesticides. Buprolord was effective against T. urticae, protonymphs. When old eggs were treated with 250 ppm of the mixture kindly results were obtained. Mortality percentages were increased directly proportional with increasing concentration of buprolord. Old eggs of the mite, T. urticae were susceptible to the tested concentrations of buprolord during 72 hr. than in 24hr. where they were more sensitive. Concentration of 250 ppm on T. urticae old eggs gave 26.06/female. On the other hand, the lowest concentration of 25 ppm gave 65.61 eggs compared with 65.35 eggs for the untreated females.
The IGR used here extended the developmental period to T. urticae by delaying the developmental rate.
Conclusively, The present study was conducted to evaluate the effect of buprolord as IGR against the two spotted spider mites (TSSM),Tetranychus urticae Koch. Buprolord was effective against T. urticae, protonymphs. Old eggs of the mite, T. urticae were susceptible to the tested concentrations of buprolord during 72 hr. than in 24hr.. The IGR used here extended the developmental period to T. urticae by delaying the developmental rate.

In order to study the effect of potassium humate on yield and some fruit properties of seedling papaya plant, an experiment was conducted at an organic private orchard located in El Mamoura at Alexandria Governorate, Egypt during 2013/2014 and 2014/2015 seasons .The experiment included four complete treatments (Soil application of 5 or 10 ml potassium humate every two months to each plant from first of March to end of August), (Soil application of 2.5 or 5 ml potassium humate every month to each plant from first of March to end of August), and control (without application of potassium humate).
The yield per plant per period from September to next May (kg) and some fruit characteristics, such as fruit weight (g), length (cm), width (cm), flesh thickness (cm), total soluble solids ( % ), total sugar ( % ), total acidity (%) and content of β carotenes (mg / 100 g of fresh) were recorded
Results indicated that Soil application of (10 ml potassium humate every two months) and Soil application of (5 ml potassium humate every month) of both seasons gave the highest yield (kg) and the differences were being significant among them and the three other treatments. Also Soil application of (10 ml potassium humate every two months) gave the highest fruit weight, length and width and significantly increased compared with the other investigated treatments in most cases, in addition the differences between flesh thickness values were not big enough to be significant between treatments in most cases. According to chemical fruit properties, the highest TSS values were obtained under Soil application of (10 ml potassium humate every two months) and significantly increased compared with the other treatments, also Soil application of (10 ml potassium humate every two months) gave the highest total sugar and significantly increased compared with the other treatments except the difference between Soil application of (10 ml potassium humate every two months) and Soil application of (5 ml potassium humate every month), was slightly not significant. A according to total carotenes, (control) gave the lowest values and significantly decreased compared with the other treatments
Conclusively, the obtained results give basis to conclude that, soil applying seedling papaya plant with potassium humate had a positive effect on yield and fruit quality. The most beneficial treatment in this concern is applying with 10 ml potassium humate every two months started from beginning of March to end of August which gave a reasonable yield and high fruit weight and dimensions with high content of TSS and total sugar and could be considered as a recommended treatment under the conditions of this experiment.

This study was carried out during the two successive growing seasons of 2013/ 14 and 2014/15 at the Farm of Soils, Water and Environ. Res. Inst., Agric., Res. Center in Sahal El-Tina (Por-saied Governorate), to investigate effects of cyanobacteria at rates of 0, 6 or 9 g/L and compost at rates of 0, 6, 8 and 10 ton /fad on growth, fruits yield, essential oil %, essential oil yield/ plant and its components and chemical composition of Fennel (Foeniculum vulgare Mill.)under soil salinity conditions.
Gradual and significant increase in plant height, numbers of branches and number of umbels/ plant, fresh and dry weights of plant, fruit yield per plant, essential oil percentage in fruits, and essential oil yield per plant were recorded with increasing the tested cyanobacteria concentration from zero up to 9 g/L. Maximum percentages of α- Pinene, β- Pinene, fenchone and anethole in the resulted essential oil also, was recorded with 9 g/L cyanobacteria while the maximum anise aldehyde % was resulted with 6 g/L cyanobacteria. Cyanobacteria at all tested concentrations reduced straggle percent.
Compost treatments especially (8 ton /fad) enhanced all growth characteristics of fennel plants. Also, maximum fenchone and anethole content and minimum estragole content was resulted with 8 ton/ fad.
Significant increase in growth characteristics was obtained with combination between 8 ton compost/fed and 9 g/L cyanobacteria.
Conclusively,it could be recommend that using cyanobacteria(CB) at 9 g/L with 8 ton /fad, compost enhanced fennel growth as well as fruit and essential oil yield and its composition.

This study was carried out to evaluate tree performance of “Fuerte” and “Hass” avocado cvs. under three different climatic conditions i.e. Shandaweel, Beni-Suef and El-Kanater, during 2014 and 2015, seasons.
The climate play an important role in flowering time, where is found the warmer climate promote oil contents than the coolest one, whereas the highest value of oil was achieved with warmer climate.
Conclusively, it can be concluded that achieving high content of oil, it should cultivate avocado under warm climatic conditions.

The aim of this work was to produce avocado mayonnaise without egg as special foods.
This study evaluated avocado (Perseaamericana, Millcvs. Hass and Fuerte) (season 2015). Dry matter, oil content and fatty acid composition were examined and compare it with Maraqiolive oil. Dry matter and oil content of both avocado cultivars were 29.77, 22.00 and 27.85, 20.30%, for Hass and Fuerte, respectively.
The results showed that avocado oils were very close to olive oil. Avocado is nutritionally rich in many health related components and a valuable energy source due to their high quality fat content.
In conclusion, avocado oil showed higher PUFA/SFA ratio than olive oil. According to total phenol contents and the lipid profile, the stability of avocado oils was similar to that of olive oil. The composition of Hass and Fuerte avocado oils were closed with this of Maraqi olive oil.
