The average reduction percentages were 99.17 and 94.06% and 100.00 and 96.38% with general mean (99.58 and 95.72%) during the two planting seasons, respectively.
The results indicate that, Biosect (<em>Beauveria bassiana</em>) compound was the most harmful alternative pesticide against the true spiders. This compound induced (70.19 and 72.94%) as an average reduction percentage during the early summer and Nili plantation, respectively. The lower toxic effect was obtained with the treatment by Prev (orange oil) where, the general mean reduction percentage after two seasons of application was 14.63%. Baicao and Neemix showed a moderate toxic effect on the population density of the true spiders.https://eajbsf.journals.ekb.eg/article_17263_adda9341f4fbf0adefb3f6c1cb397173.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences, F.

Prepared formulations<br />sprayed on tomato plants at concentrations 1.0, 1.5 and 2.0% (V. /V.). Direct<br />effect on present 2<sup>nd</sup> and 4<sup>th</sup> instar larvae of cotton<br />leafworm was determined by takeing tomato leaves samples directly after<br />spraying and introducing these leaves samples to larvae in laboratory, for<br />studying latent effect,treated leaves samples were taken each two days and<br />introduced to the rest alive larvae ,mortality counts was recorded each two<br />days,then mortality percentages were calculated.Residual effect was determined<br />by the same method mentioned before,by taking leaves samples after 7 days of<br />treatment and introduchngto larvae in laboratory, other samples taken each two days and introduced to the<br />rest alive larvae. Antifeedent effect also was determined by determination the consumed<br />amount of treated tomato leaves and untreated, then reduction percentage in<br />food consumed was calculated. Results<br />obtained indicated that the tested matrials at all tested concentrations showed<br />hightoxic effect directly against the present larvae or residual after7days<br />against new infestation if occurred .Also, the tested materials showed<br />antifeedent effect against 4<sup>th</sup> instar larvae to be more than 50% at<br />1% concentration. For economic consideration,concentration 1% could be<br />recommended for controlling larvae of cotton leafworm infested tomato.https://eajbsf.journals.ekb.eg/article_17264_0b8bf20af74a2b78280bbc46a4dcbaad.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences, F.

Recently, the alternative control based on natural products extracted from medicinal and ornamental plants as control agents for the <em>Varroa</em> mite considered more save to human being and bees. plant extract of Thyme , mixture of Fenugreek & Santonica, Fenugreek alone and Santonica alone were evaluated against <em>Varroa </em>mite at the apiaries located at Sebha, Lybia during (March – April), 2012.
The data clearly show that, an increased the efficiency of any extracts used for <em>Varroa</em> control with the superiority of Thyme followed by mixture of Fenugreek & Santonica, Fenugreek alone and finally Santonica alone. This extracts caused an obvious reduction of the rate of infestation either in the sealed brood or on the adult bees, moreover increase in the number of sealed worker brood cells and, lastly, an increase in the number of combs covered from both sides with adult worker bees (colony strength) in the treated colony.https://eajbsf.journals.ekb.eg/article_17265_077e789c0ac8a2de759006dfd8edc969.pdfEgyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences, F.

All of the four composites diluted to 3% before applying for four times in each spray. Samples were taken at the first, fifth, seventh and tenth days after application to determine the reduction in numbers. The results showed that, garlic oil wasthe best efficient in reducing the population of leafhoppers and planthoppers by a mean reduction percentage of 68.09%, followed by the two chemical insecticides Dimethoate 67.90 % and Pestban 64.02 %, and Eucalyptus oil was the least in this category as 43.27 %. However in controlling aphids, also garlic surpasses again by a mean overall reduction 90.96 %, followed by Pestban 89.44 %, while eucalyptus oil came in the third rank as 80.66 % before the dimethoate which achieved the least rank in controlling aphids as 76.14 %. Furthermore experiment was conducted also to evaluate the side effects of such composites on the population fluctuations of two insect predators rife in Fababean fields, true spiders and minute pirate bug (<em>Orius</em> sp.). Data showed that, in compared with control, the use of natural oils preserved partly the coexist of natural enemies than the use of chemical compounds in Faba bean fields.https://eajbsf.journals.ekb.eg/article_17266_d1cdce9f0c0ecb6e41d6576e66465db6.pdf
