Acaricidal Activity of Essential Oils of Chamomile, Marjoram and Eucalyptus against the Two-Spotted Spider Mite, Tetranychus urticae Koch: Biology and Enzymes
Different concentrations of three essential oil extracts (0.5, 1, 2, 3 and 4%) were used against Tetranychus urticae.(Koch) Chamomile; Chamomilla recutita (L.), proved to be the most efficient agent against T. urticae followed byMarjoram; Marjorana hortensis (L.), and Eucalyptus (Eucalyptus sp.) The LC50 values of these oils were 0.651 &1.17;1, 84 & 6.26 and 2.18 & 7.33 for adults and eggs, respectively. Herein, the bioassay experiments of the two essentialoils, Chamomile and Marjoram showed relationship between essential oil contents and activity of enzyme glutathioneS-transferase, non specific esterase and alkaline phosphatase in T.urticae. GC-MS analysis of C. recutita and M.hortensis proved the presence of 13 and 14 essential oil components, respectively. The major essential oil contents of C.recutita are α-Bisabolol oxide A (35.25%), and Trans-β-farersene (7.98%), while the main components of M. hortensisare Terpinen-4-ol (23.86%), P-cymene (23.40%) and Sabinene (10.90%). The major components of both plant extracts(Terpinen-4-ol 23.86% and α-Bisabolol oxide A 35.25% essential oils) may be responsible for the activity of enzymesof T. urticae (glutathione S-transferase, non specific esterase and alkaline phosphatase).

New Acarine Setal Receptors of Varroa Destructor
The female mite nymphs of Varroa destructor Anderson and Truman were collected from sealed worker and dronebrood cells and prepared for the scanning electron microscopic examination to identify type and structure of the setaereceptors present on the leg I. Eighteen setae types were recorded and described. Thought they can perceive beeassociated volatiles by means of receptors in wall-pore sensory hairs of the tarsal pit organ and legs.

Laboratory Studies on Spinosyns Compounds Against Different Pests
Spinosyns are new neurotoxins mixtures produced during fermentation of a soil actinomycete that have high activitytowards different pests. Spinosyns compounds were represented in Spinosad and its evoluted compound ,Spinetoram,which were tested for their toxic effects under laboratory conditions against adult females of Aphis gossypii Gloverand Tetranychus urticae Koch ,and the fourth instar larvae of Spodoptera littoralis (Boisd.)by leaf-dip technique.Spinosad LC50's of A. gossypii , T. urticae and S. littoralis were 30.417,25.982 and 5.379 ppm, respectively but theywere 0.596,0.370 and 1.742 ppm,respectively in case of Spinetoram.The superior Spinosyn compounds,Spinetoramgained the best results against piercing-sucking pests compared with Spinosad which was the best against S. littoralis,so the present histological studies were concerned with Spinetoram.Each pest was treated with its LC50 value.Histological defects after treatments in the neuromuscular nicotinic receptors were detected and discussed.

Metabolic Resistance Mechanisms of Different Pesticides in The Two-Spotted Spider Mite, Tetranychus urticae Koch (Tetranychidae:Acari)
An investigation was performed to determine the possible role of detoxification metabolism in resistant strains ofTetranychus urticea Koch.Adult females were subjected to selection pressure through 40 generations by LC50's andLC90's of Vertimec (Avermectines), Cypermethrin (Pyrethroids), Methomyl (Carbamates) and Malathion (O.P), were(41.308, 42.021, 44.881, and 49.265 folds) and (49.815 ,55.411 ,63.972 ,and 90.00 folds), respectively, whereas RRSslopes ranged from 0.884 to 1.395 folds. Comparative assay with esterases (EST) and mixed function oxidases(MFO)showed that LC50's of Mal-Resistant strains had higher EST. activiy (4.71) with lower MFO activity (3.80),while,LC50's of Vert-Rresistant strains had lower EST. activiy (2.70) with higher MFO activity (4.26). Synergist experimentsshowed low synergism by S,S,S tributylphosphorotrithioate (DEF) of EST activiy ranged from 4.81 to 2.99 folds,whilesynergism by Piperonyl Butoxide (PBO) of MFO activity ranged from 4.27 to 3.82folds to LC50's pesticides resistantstrains.

The Cunaxid Mite Neocunaxoides andrei (Baker & Hoffmann) as a Biological Control Agent of the Root-Knot Nematode Meloidogyne javanica Chitwood
Feeding capacity of the cunaxid mite Neocunaxoides andrei (Baker & Hoffmann) and its feeding capability on the rootknotnematode Meloilogyne javanica Chitwood, under laboratory or semi field conditions were studied. Results showedthat, a female of N. andrei consumed an average of 177.2 second juvenile stage (j2s) of M. javanica within five daysunder the laboratory conditions of 26 ± 1°C and 70 ± 5% R.H. Data also indicated that, the presence of 20, 40 and 60newly emerged N. andrei females together with 500 j2s M. javanica in pots planted with tomato seedlings 15 days oldcaused a reduction of about 59 %, 74 % and 86 % of M. javanica reached adult females after 30 days.

Typhlodromips swirskii (Acari: Phytoseiidae): A Predator of Eriophyid and Tetranychid Mango Mites in Egypt
The predacious mite Typhlodromips swirskii (Athias-Henriot) successfully developed to the adult stage when fed on themotile stages of the mango bud mite Aceria mangiferae Sayed, the mango rust mite Metaculus mangiferae (Attiah), theleaf coating mite Cisaberoptus kenyae Keifer and nymphs of the mango red mite Oligonychus mangiferus (Rahman andSabra) in the laboratory at different temperatures and relative humidities. The increase of temperature degree anddecrease relative humidity from 25°C and 60% R.H. to 30°C & 55%R.H. and 35 °C & 50 %R.H. shorteneddevelopment and increased reproduction and prey consumption. Different eriophyid prey species promoted fasterdevelopment of the predator compared to feeding on the tetranychid nymphs. The rate of egg laying (2.62, 2.23, 2.35and 1.83 eggs/♀/day) was recorded at the highest temperatures and lowest R.H., while the minimum reproduction (1.92,1.72, 1.62 and 1.20 eggs/♀/day) was noted at the lowest temperature and highest R.H. when fed on the fouraforementioned prey species, respectively. Life table parameters indicated that feeding T. swirskii on A. mangiferae ledto the highest reproduction rate (rm = 0.216 and 0.157 females/female/day), while feeding on O. mangiferus gave thelowest reproduction rate (rm= 0.183 and 0.133) nymphs at 35°C and 50%R.H. and 25°C and 60% R.H., respectively.The adult predatory female consumed an average of 117.8 A. mangiferare, 114.18 C kenyae, 94.4 M. mangiferae motilestages and 14.58 O. mangiferus nymphs at 35°C and 50% R.H./day, while it devoured 102.8, 96.59, 90.44 and 12.35individuals, respectively at 25°C and 60% R.H. The three eriophyid mango mites, particularly A. mangiferae, proved tobe suitable prey for T. swirskii, as a facultative predator, compared to the tetranychid mango mite.

Ecological, Biological and Control Studies on the Leaf Coating and Webbing Mite Cisaberoptus kenyae Keifer (Eriophyoidea: Eriophyidae) in Egypt
The leaf coating and webbing mite Cisaberoptus kenyae Keifer was observed for two years in an abandoned mangoorchard in Egypt. The eriophyid mite was fed upon by the two predatory phytoseiid mites Typhlodromips swirskii(Athias-Henriot) and Typhlodromus mangiferus Zaher and El-Borolossy. Population dynamics of the eriophyid mangoprey were affected by climatic conditions, predation, shady and sunny zones and vertical distribution. About 16 & 18;and 15 & 13 generations were recorded for C. kenyae on cvs. «Hindi and Alphonso» during two successive years,respectively. Leaves at bottom levels of both mango cultivars were found preferable to the mite feeding than those atthe top and middle. Higher temperature enhanced faster development of C. kenyae. A control measure of one treatmentwith acaricides in the winter after budding resulted in effective control.
