The red palm weevil ( Rhynchophorus ferrugineus ) is a devastating pest of palms in the Mediterranean, Middle East, and Eastern countries. Survey the natural enemies were conducted during two successive years (2009and 2010) in Dakahlia governorate. The RPW in date palm has been managed with an integrated pest management (IPM) approach comprising several tactics including the biopesticides based on insects, mites, predators to control. In this study, the susceptibility of different date palm cultivars to the RPW infestation was determined and a survey of the natural enemies of the RPW in Dakahlia governorate was conducted. The obtained results showed that red palm weevilinside cocoonsstages wereattacked by the ectoparasitoids mites; Uropodina phoritic and Aegyptus rhynchophorus. On the other hand recorded local strain of Beauveria bassiana mycosis disease on RPW was verified. Also Anisolabis maritime predator eggs of the RPW.
The parasitism showed three peaks each year. The high parasitism of the mites start with in the beginning of January then increased gradually to reach the first peak at the 4th week of January, 2nd week of February and 2nd week at April these peaks were recorded during 2009. Also during season 2010 the first peak at the 2nd and 4th weeks of March and 2nd week of April. Also the pathogenic fungus B. bassiana exhibited three peaks of seasonal activity each year. These peaks were recorded during 2009 in February, March and May. While, the second season (2010), of activity was recorded from the January to the June and these peaks were recorded in February, April and May. Data indicated that there was significant positive correlation between average temperature and the parasitism. So it's with the pathogenic fungus, abundance on the RPW, the studied two year. While relative humidity had negative effect.

Economic Entomology Dept., Fac. of Agric., Damietta University, Egypt.
The present study were carried out during seasons 2009/10 and 2010/11 in Qalubia Governorate. The citrus mealybug Planococcus citri (Risso) nymphs had four peaks of abundance during the first season in 14th June 2009, 9th August 2009, 13rd December 2009 and 21st February 2010. Moreover, the insect adults had also four peaks of abundance in 17th May 2009, 28th June 2009, 9th August 2009 and 21st February 2010. While in the second season insect nymphs had five peaks of abundance in 18th April 2010, 25th July 2010, 3rd October 2010, 28th November 2010 and 20th March 2011. While the insect adults had also five peaks of abundance in 2nd May 2010, 3rd October 2010, 14th November 2010, 26th December 2010 and 3rd April 2011.
Six citrus species were screened during two seasons for susceptibility to citrus mealybug P. citri in Qalubia orchard. In the first season 2009/10 Clemantine mandarine and Balady mandarine were the least infested species by the insect with the mean numbers of 20.9±3 & 21.4±2.1 nymphs and 12.8±1.9 & 9±0.8 adults, respectively. While, Sour orange and Lemon were the heaviest attacked by the insect with the mean numbers of 152.3±17.5 & 150.3±8.8 nymphs and 84.3±10 & 76±4.7 adults, respectively. Navel orange and Persian agami were moderately infested by P. citri with the mean numbers of 58.1±6.7 & 38.7±5.8 nymphs and 33±4 & 23.7±3.8 adults, respectively. In the second season Lemon and Sour orange were the heaviest infested by the insect with the mean numbers of 172.2±21.1 & 119±8.3 nymphs and 104.1±13.8 & 67.7±5.4 adults, respectively. While, Persian agami and Navel orange were moderately susceptible to infestation where the recorded mean numbers were 32.8±2.1 & 52.5±6 nymphs and 18.5±1.6 & 27.9±2.5 adults, respectively. Clemantine mandarine and Balady mandarine were the lowest susceptible to infestation with the mean numbers of 23.2±4.9 & 32.3±6 nymphs and 11.4±2.2 & 18.4±3.4 adults, respectively.
Volatile oils were analyzed in tested citrus species so that different levels of susceptibility in citrus species to P. citri infestation may be correlated to different kinds and percentage of components of volatile oils. Sour orange which was the heaviest infested was characterized by the highest rates of Champhor and Linalool, and Lemon which came the next after Sour orange showed highest rate of Carvon and d-limonene.
The efficacies of four insecticides (Confidor 20% SL., Vertimec 1.8% EC, Castor oil 30% and Mesrona oil 85% EC) against P. citri on 35 – years – old trees of Navel orange were evaluated. Mortalities were recorded after 3, 7, 14, 21 and 30 days of treatment. Confidor was the most effective compound followed by Vertimec, while Mesrona oil and Castor oil gave reductions in population rate after 30 days from application to 82.2 and 68.6% respectively. Three weeks later, the activity of both Confidor and Vertimec had decreased rapidly, however mineral oil had longer residual effect and less harmful to natural enemies.

This study was conducted to evaluate the toxic and biochemical effects of multiple applications with Biofly(Beauveria bassiana) and SpinTor® (spinosad)on nurse and field honey bee (Apis mellifera L.) workers under laboratory conditions. The mortality percentages of workers treated with both biopesticides were determined after 24 h of one, two and three daily applications. The lethal concentrations of spinosad that caused 50% mortality (LC50) were estimated. The effects of two biopesticides on the acetylcholinesterase (AChE) activities in heads, thoraces, and abdomens of surviving nurse and field workers were determined in vivo after 24 of single, two and three daily applications. The results indicated that spinosad was higher toxic than Biofly to both nurses and field worker. Also, the mortality percentages after 24 h of three daily applications of Biofly and spinosad were higher than that of two daily applications whatever worker type. In the same pattern, the mortality percentages after two daily applications were higher than that of single application. On the other hand, Biofly and spinosad were more toxic to foragers than to nurses after 24 h of one application, or two or three daily applications. Furthermore, our findings indicated that mean values of AChE activity in heads of nurse and field workers fed sugar syrup with 0, 187.5, 375, 750, 1500 and 3000 mg L-1 of Biofly, and 0, 2.5, 5, 10 and 20 mg L-1 of spinosad were higher than those in both thoraces and abdomens after 24 h of all treatments. Also, the average of AChE activities in heads was significantly (p > 0.05) higher than that obtained in both thoraces and abdomens whatever tested biopesticide, worker type or number of applications. In addition, tested concentrations caused various degrees of inhibition and activation in AChE activity in heads, thoraces and abdomens when compared with controls. Summed data revealed that Biofly and spinosad increased AChE activity of both worker types after 24 h of applications however it repeated or not.

The seasonal activity of Kilifia acuminate (Sign.) on mango trees was studied for two successive years (March, 2011 to mid-February, 2013) in a privet farm cultivated with mango trees at El-Saff, Giza Governorate. The obtained results revealed that, K. acuminata has two overlapping generations on mango trees per year. The 1st generation (spring generation) started from early March in the both years, peaked in early May and extended to mid-August in the 1st year and late July in the 2nd one. The generation duration ranged 5.0 - 5.5 months in the two years at 24.6 - 25.0ºC & 55.3 - 56.2%R.H. The generation size ranged 92.0 - 99.6 nymph/leaf and 69.6 - 79.3 adult/leaf with total population ranged 161.6 - 178.9 insect/leaf in the two years, respectively. The 2nd generation (autumn generation) occurred between early July and mid-February, peaked in early/mid-October in the both years. The generation duration lasted for 8 months in the two years at 22.3 - 22.6ºC & 659.7 - 60.1%R.H. The generation size ranged 121.4 - 129.7 nymph/leaf and 99.1 - 109.1 adult/leaf with total population ranged 220.5 - 238.8 insect/leaf in the two years, respectively. The insect population recorded with minimum numbers in June, July and early August in the two years. The population of both nymphs and adult females ranged 63.9-75.2 nymph/leaf and 45.1-71.3 adult/leaf; the total population ranged 109 - 150.4 insect/leaf at 29.4-30.5ºC & 56.1 - 57.1 R.H. %, respectively. The optimum range for insect activity ranged 24.6 - 25.0ºC for spring generation and 22.3 - 22.6ºC for autumn generation. Statistical analysis indicated that the insect population exhibited positive response to the increase of daily mean temperature in both years. The changes in the half monthly counts of nymphs and adult females population referred to the combined effect of daily mean temperature and %R.H. on the spring generation (1st generation) were 82.1- 82.5% & 73.5 - 82.4% for 1st and 2nd year, respectively. The effect of both tested weather on the nymph and adults in the autumn generation (2nd generation) were 85.1 - 90.9% & 75 - 79.5% for the 1st and 2nd year, respectively.

This research work was carried out under greenhouse condition to evaluate three different honeybee products i.e. royal jelly, bee venom and propolis at different concentrations to control root-knot nematode, Meloidogyne javanica, on tomato plants. Results of this study revealed that all tested honeybee products at all concentrations significantly reduced all nematode parameters when compared with the treated plants with nematode alone. Applying the royal jelly at the rate of 1% was the highly effective in reducing all nematode parameters. The highest percentages of reduction in number of galls, egg-masses, developmental stages, females/root system, juveniles in soil, final nematode population (PF) as well as the reproduction factor (RF) were showed with this treatment by 97; 99; 100; 100; 92; 98 and 98%, respectively. The treatment of royal jelly at the concentration of 2% was the second effective one followed by bee venom in the third rank at the concentration of 0.005%. The lowest reduction obtained with the propolis at all tested concentration. Results also showed that all honey bee products at all concentrations enhanced markedly all plant growth parameters i.e. plant height; root length; fresh shoot and root weight. Results revealed that all applied treatments maintained on the cell wall and reduced the membrane permeability compared to plants treated with nematode alone. The lowest percentage membrane permeability (membrane leakage%) was found with the royal jelly at 1% as it reached 26% compared to the treated plants with nematode alone (reached 97%). The contents of the amino acid proline in plants was also affected with the applied treatments as the highest proline content was obtained with the same treatment of royal jelly at 1%.

Nematicidal activity of 12 monoterpenes namely, camphene, (R)-camphor, (R)-carvone, 1-8-cineole, cuminaldehyde, (S)-fenchone, geraniol, (S)-limonene, (R)-linalool, (1R,2S,5R)-menthol, citral and thymol was evaluated against root-knot nematode, Meloidogyne incognita J2 in-vivo and in-vitro on eggplant cv. Black Beauty (Solanum melongena L.). In laboratory experiments, all of the tested compounds caused significant mortality of the second larval stage (J2). It was, also, noticed that the tested compounds reduced egg hatching. Carvone, cuminaldehyde, thymol, geraniol, and citral showed the highest nematicidal activity among the tested monoterpenes in vitro. The results of greenhouse experiment clarified that the tested monoterpenes; carvone, cuminaldehyde, thymol, geraniol, and citral, significantly, reduced numbers of root galls, egg masses and population of nematodes of eggplant at concentration 250 mg/kg soil compared to the inoculated control. Carvone was the most effective treatment in reducing root galls, egg masses and final population of the nematode except for oxamyl. Results revealed that all of the tested treatments increased various measures of plant growth characters with the reduction in the root- knot infestation. Among all of the tested monoterpenes, carvone followed by cumminaldehyde were the most effective treatments to increase both fresh shoot & root weights and lengths. None of the compounds was phytotoxic at the tested treatments. Results stated that monoterpenes exhibited significant nematicidal activity in-vitro and in-vivo experiments and could be considered as useful natural namaticidal agents.
