Studies For Bulting The System Of Main Pests In Horticultural Experiment Station Of Northwest A & F University

The horticultural experiment station of Northwest Agriculture and Forestry University that the station is located in Shaanxi Guanzhong area, smooth terrain, site area is 6 hm2, have various fruit trees such as apple , pear , apricot , peach , grape , persimmon , kiwifruit and various vegetable , flowers and plants such as Crucifer , Solanaceae , Cucurbitaceae , Liliaceae , to have the various wild breed and kind of domestic and overseas germplasm resources more than 80 kind among them ;That the species is rich , plant diseases and insect pests happens comparatively representative , is scientific research and important teaching base.The research devoted to built the monitoring system of main pests in horticultural experiment station, applying some kinds of technologies on monitoring and forecast , knowing what pests happened in the horticultural experiment station and the trends , the capacity occurring is done out in statistics about the main pests , and to know other correlation factors of combination , such as climatic factors,environment condition,etc. Studying the occurrence regularity and the change trend of them, realize the dynamic monitoring to the pests, to ascertain the various measure to pests integrated control , To make the maximum economic efficiency with the smallest investment. As the instruction to develops each kind of big area countryside by the monitoring system of main pests and the reasonable diseases and pests control.Study result as follows:1.The horticultural experiment station is composed of 145 kind of arthropod community, belongs to 2 class, 11 order and 80 family. Phytophages have106 species, belonging to 54 family; Predator have 29 species, belonging to 17 familly; The detritivores have 7 species, belonging to 7 family; The parasitoids have 3 species, belonging to 3 family. With the wing item, the Homoptera, Coleoptera, Lepidoptera, Arachnoidea and the Orthoptera had a large quantity, constituted community's principal constituent; and the aphid is the dominant species. The soil insect is main the Holotrichia oblita Fald, the Agrotis ypsilon Rott. and the Pleonomus conaliculatus Fald.. Natural enemy's type is rich, the number of individual are many, can have the control influence to the pests population quantity. 2. The horticultural experiment station whole year always tempts the moth quantity 16856 heads, the average is 843/bowls. The Carposina Sasakii Matsumura and the Adoxophyes Orana 's occurrence quantity are quite small, has not achieved the control index; But theGrapholitha Molesta (Busck ) and Asiatic apple leaf-miner needs to carry on the control.3.With the black-light lamp capacity trapping and killing the insect is 25731 heads altogether ,including 8 oders, 62 family, 241 species; To the main pests, like the Anomala corpulenta, the Holitrichia oblita, Proagopertha lucidula Faldermane, the Aphid, the Manestra brassicae Linne the trapping and killing effect is obvious, and the influence is small to the natural enemy. the phytophages'proportion is big. May know each kind of insect's occurrence regularity of development using the black-light lamp, the adults worm emergence activity cycle, has the effect of forecast.4. The collection of insects that the sweet-sour fluid trapped is 11860 heads in the whole year . Treatmentâ…¡(Sugar: Vinegar: Liquor: Water =6: 3:1:10) achieve the best effect, trapping most insects. Treatmentâ… t rapps the Lepidoptera insect to be the most, Treatmentâ…¡,â…¢trapps the Coleoptera to be the most.5. this research proposed the main pests monitoring system 's complete conception, and utilizes it initially, has achieved the good ecological benefit, the economic efficiency and the social efficiency.
