Zizyphus jujuba Mill.Cv.dongzao is a major economic species of the north-west region ofShandong Province, has developed rapidly in the past10years, the extent of cultivation hasincreased year by year to the national radiation, pest occurrence trend of more and moreserious by extensive management, direct impact the economic and social benefits ofZizyphus jujuba Mill. Cv. Dongzao garden. The Zizyphus jujuba Mill. Cv. dongzao garden isa habitat for many arthropods,some of them harm branches, leaves, flowers, fruit of Zizyphusjujuba Mill.Cv.dongzao trees, the light weaken tree vigor production, serious noproduction,some pests for food or parasitic thereon, plays an important role in the jujube pestcontrol, insect community plays an important role in guiding the pest control practice. We arerequired to use the principles and methods of integrated pest management, improve the levelof Zizyphus jujuba Mill.Cv.dongzao forest pest management.1Arthropod community structure and diversity in Zizyphus jujuba Mill.cv.dongzao gardenWere identified arthropods137species, belonging to two classes,15orders,71families,145species; including Lepidoptera, Coleoptera, Orthoptera, Hemiptera, Diptera, Homoptera6orders accounted ratio than large, six major groups accounted for66.20%of all subjects,84.68%of the number of species, more than60%of the total number of individuals.Zizyphus jujuba Mill. Cv. dongzao garden insect community diversity index change trend:in the low temperature of5and10month, insect populations is relatively small, but thenumber of individuals of each species were similar, arthropod distribution is relativelyuniform, so instead of diversity is higher.In the temperature appropriate season, insects isuneven distribution of individuals because more advantage insects accounted for theproportion of high results in the decrease of community diversity.2Population dynamics and tropism of Apolygus lucorum Meyer-Dur2.1Population dynamics of Apolygus lucorum Meyer-DurApolygus lucorum Meyer-Dur Mayer has five generations one year in the Zizyphusjujuba Mill.Cv.dongzao garde of Huimin in Binzhou. The newly hatched nymphs saw inApril6,rainfall for its created humidity conditions to start neat hatch in April13, the firstgeneration fundatrices in Seventeen May, the second-generation fundatrices in Twenty five June; affect the jujube germination and fruit, generation overlapping is common after thesecond generation, Apolygus lucorum spawning on jujube residues chunks for overwinteringfrom outside in late September,2.2Tropism of Apolygus lucorum Meyer-Dur2.2.1Tropism of plantDifferent trapping material (mung bean, sunflower, cotton) plant in Zizyphus jujubaMill.Cv.dongzao gardeļ¼Œthe evidence effect of attracting insects show by green beans andsunflowers, no significant evidence effect of attracting by cotton. The highest attract up toeight on one stem.2.2.2Tropism of different color lampThe sesult of Apolygus lucorum Meyer-Dur trapping by different colors (orange, blue,green, white) lamp: The optimum moth-killing is the blue moth-killing lamp, the peak appearsin the July2to33head/lamp, no significant difference trapping effect in the other threecolor.
