The present work was carried out at El-Katta village to evaluate the efficiency of six synthetic insecticides (Pyriban<sup>®</sup>, keiton<sup>®</sup>, Egycron, Fenthion<sup>®</sup>, Fury<sup>®</sup>, and Regent<sup>®</sup>) and two bio-insecticide (Biovar<sup>® </sup>(<em>Beauveria bassiana</em>) and Avermectin<sup>®</sup> (emamectin benzoate)). Insecticide solutions were injected into three holes against the immature stages of Red Palm Weevil (RPW), <em>Rhynchophorus ferrugineus</em> (Olivier) (Coleoptera: Curculionidae). Three concentrations of each tested insecticides (0.3%, 0.6 and 0.9%) were used. The insecticides were applied at rate of one liter per tree. The numbers of recovery palm trees were investigated every week and recorded after forty five days from treatment. The obtained results showed that the most effective insecticide was Pyriban<sup>®</sup> and Keiton<sup>®</sup> (62.5%), followed by Egycron<sup>®</sup> (58.3%), Fenthion<sup>®</sup> (37.5%), Fury<sup>®</sup> (29%), and Reagent<sup>®</sup> (25%). The bioagents were less effective than synthetic insecticides; Biovar<sup>®</sup> (12.5%) and Avermectin<sup>®</sup> (4.1%) at 0.3% concentration.

Laboratory experiments were carried out in order to evaluate the predaceous efficiency of the earwig, <em>Labidura riparia</em> Pallas against the red palm weevil (RPW), <em>Rhynchophorus ferrugineus</em> immature stages. Obtained results showed that the 6<sup>th</sup> nymphal instar of <em>L. riparia</em> was the most predacious stage on all RPW immature stages. However, the 1<sup>st</sup> nymphal stage of <em>L. riparia</em> had the least predacious rate on all RPW immature stages. In addition, results showed that all immature stages of RPW were preferred for consumption by the earwig nymphs. The rate of consumption of immature stages of the RPW was increased by the age of the nymphal stage. Results showed that the 6<sup>th</sup> instar nymphs had the longest feeding duration upon all immature stages of RPW. Finally, the earwig, <em>L. riparia</em>, can be considered as a promising natural enemy to minimize the red palm weevil population density.

During the last few years a new disease symptoms appeared and spread on mango trees in Ismailia Governorate from which <em>Ganoderma</em> sp. was frequently isolated. The disease starts as rot in the basal area of mango trees, followed by the growth of distinctive structures known as "brackets" and finally plant death. Three isolates is of <em>Ganoderma</em> sp. were isolated for the frist time from naturally infected mango trees in three locations at Abo-Swear district El-Karakrah , Abo-Kharwae and El-Wasfia) , Ismailia Governorate , Egypt . Microscopic examination of isolated pure cultures showed hyphal system trimitic(generative hyphae , skeletal hyphae and binding hyphae),basidiospores and chlyamidospores.) of <em>Ganoderma</em> sp. Pathogenicity test on mango transplants , with<em> </em>isolated <em>Ganoderma</em> sp., under greenhouse conditions revealed that <em>Ganoderma</em> sp. was pathogenic and it caused sudden wilt root rot and dieback causing wilt to inoculated mango transplants. In the same time, results indicate that the artificially inoculated discs of different other fruit and wood trees (Host range) in their susceptibility to the pathogen under study based on the external rotted discs of tested woody plants. Mango and kaki exhibited 100% of rotted discs two week after inoculation. On the contrary, no fungal growth was observed on inoculated guava and olive discs under the same conditions. In the meantime, <em>plum</em><em>, </em>casuarina and <em>berry </em>showed 77.8, 62.0 and 56.8 % infection in inoculated discs, respectively .Starch and mannose used as carbon source recorded a noticeable increase in the linear growth of <em>Ganoderma</em> sp. study followed by sucrose in Ganoderma growth medium, maltose and manitol. The tested fungus gave maximum growth rate on Yeast extract 10 days after incubation at 25 <sup>o</sup>C followed by Molt extract, Peptone and Ammonium sulphate which found to be best source of nitrogen for this fungus. The optimum temperature for the linear growth of <em>Ganoderma </em>sp. ranged from 20 to 30 <sup>o</sup>C. <em>T. harzianium</em> recorded the highest percentage of inhibition against <em>Ganoderma sp. </em> followed by <em>T. virens</em>. However, <em>Chaetomium globosum </em>showed the lower percentage of inhibition.

The present experiments was carried out in both experimental farm and laboratory of Plant Protection Research Institute, Sakha, Kafr El-Sheikh Governorate to study the population abundance of the Egyptian alfalfa weevil (EAW) and find out the influence of host plants on some biological aspects of<em> Hypera brunneipennis</em> (Boh.). Results indicated that by sweep net this insect adults had two peaks in January and April, while by photoelector recorded one peak in Apr. the larvae of EAW peaked once in March by the two methods during the two successive seasons.
The average number of the insect adults were 2.3±1.1 and 2.2±0.9 indiv./50 double strokes by the two methods sweep net and photoelector during the first season 2011/12, respectively. While, The average number were 5.9±3.2 and 5.7±2.7 indiv./50 double strokes during the second season 2012/13, respectively. The average number of the insect larvae were 11.6±6.8 and 11.9±7.3 indiv./50 double strokes by the two methods sweep net and photoelector during the first season 2011/12, respectively. While, The average number were 76.3±54.7 and 61.3±46.6 indiv./50 double strokes during the second season 2012/13, respectively.
The total period from the larval stage until the adult stage were the shortest (26±0.6 days) when the EAW was reared on Egyptian clover and the longest periods (34.8±0.5 days) were recorded on kidney bean with Significant differences according to different host plants.The adult longevity was the longest when the EAW was reared on Egyptian clover followed by fenugreek and Kidney bean with significant differences according to different host plants. The survival percentages of the larval stage and pupal stage were the highest (94.0% and 94.1%) when reared on Egyptian clover and the lowest percentages (65.0% and 83.3%) were recorded when the EAW reared on Kidney bean, respectively.

This study aimed mainly to estimate the resistance of the cotton leafworm <em>Spodoptera littoralis</em> to several bioinsecticides (Spnitor, Protecto, Dipel DF, Dipel 2X, Agrine and Radical) throughout determining the resistance ratio values. Among all the tested bioinsecticides, Radical had the highest resistance ratio in the four Governorates, while, Spnitor had the lowest resistance ratio in all these Governorates. The relative toxicity of these bioinsecticides to <em>S</em>.<em> littoralis</em> was also determined. The results clearly indicated that Radical was the most toxic bioinsecticides in all four field strains followed by Spnitor, while the other bioinsecticides were the least toxic action.

The development of resistance and biochemical mechanism of the cotton leafworm, <em>Spodoptera littoralis</em> (Boisd.), to five insecticides (chlorpyrifos, profenofos, cypermethrin, spinosad and flufenoxuron) were studied in the laboratory. The parent strain of <em>S. littoralis</em> was collected from El-Fayom Governorate at the cotton season 2005 and reared under laboratory conditions for seven generations, then subdivided into five sub-strains, three of them were selected by chlorpyrifos, profenofos and cypermethrin for fourteen generations and two were selected by spinosad and flufenoxuron for twelfth generations at LC<sub>30</sub> level. Selection pressure in all experiments was carried out on 4<sup>th</sup> instar larvae by the leaf dipping technique. At the end of selection, the results indicated that the resistance ratios (RR) were 16.30-, 40.23-, 1070.42-, 145.14- and 8.24-fold for chlorpyrifos, profenofos, cypermethrin, spinosad and flufenoxuron, respectively, compared with the parent strain. At the end of selection pressure, detoxifying enzyme assays revealed that the α-esterase activity levels for such insecticides were 4.64, 4.67, 3.10, 3.40 and 1.24 times, respectively, higher than in the parent strain whereas those of β-esterase activity were 4.16, 4.07, 3.11 and 3.64 times for chlorpyrifos, profenofos, cypermethrin and spinosad, respectively, higher than in the parent strain, on the contrast the β-esterase activity for flufenoxuron was 0.96 time lower than in the parent strain. In addition, the levels of glutathione S-transferase (GST) activity at the end of selection with these insecticides were 6.62, 6.43, 2.11, 4.69 and 1.32 times, respectively, higher than in the parent strain. The results showed a correlation between the activity of both non-specific esterases (α- and β-esterases) and GST and resistance level to the tested insecticides. The results, also, indicated that the broad spectrum of insecticide observed in the field populations was due to multiple resistance mechanisms, including their increased detoxification. Finally, the rapid assessment of esterases and GST activities may be useful for monitoring resistance to these insecticides in <em>S. littoralis</em>. Therefore, differential levels of such enzymes could likely be used to detect the development of resistance during the early stages of insecticide resistance in the field.
