Description
Technical field
The present invention relates to the plant protection field, more particularly, relate to a kind of utilize insect pheromone lure core lure the collection its male imago of the same race method for enticing collection, lure acquisition means.
Background technology
Rice leaf roller is one of Asia insect pest of rice, and is huge at the area of China's annual generation disaster, for preventing and treating its harm; Annual cost pesticide cost is high; Not only polluted agricultural land, kill and wound beneficial organism, lower bio-diversity, the reproduction rate that also stimulates plant-feed insects such as rice fulgorid causes to increase wildness again; Strengthen medication once more, therefore be considered to the person of exciting that the rice field pest is taken place.In view of this, the generation of early monitoring rice leaf roller dynamically is to reduce the important step that unnecessary chemical pesticide uses.
At present the main tool method of generations of monitoring rice leaf roller, its emergence period of prediction, generating capacity is: catch up with moth, female moth ovary to dissect, look into ovum, the growth and decline of larva population, residual worm amount in the field, look into rice leaf that larva harm the causes rate (comprising leaf roll, " worm is luxuriant ") of being injured.(coming from: observe and predict standard GB/T 15793-2009 rice leaf roller and observe and predict technical specification).
The rice leaf roller sex pheromone be its female moth discharge in order to attract the come signal compound of mating of male moth, clearer and more definite its main component be along 11-vaccenic acid aldehyde, along 13-vaccenic acid aldehyde, along the pure and mild suitable 13-oleyl alcohol of 11-vaccenic acid.
Had at present different product men to produce, formulation then has the rubber head dummy to lure core, capillary type to lure core, and the trapper that matches has basin trapper, viscose glue type trapper, and the male moth of rice leaf roller is had different attracting abilities.
The A type that Tokyo Univ Japan insect research department provides (the female pheromone component characteristics of tool Japan population) is to lure 11 (in late September, 1999)～35/haftplattes of collection to lure core (in late August, 1998) every night at Fuyang, Zhejiang moth appearance top.(come from: Lai Fengxiang, Yao Qing, Zhang Zhi's great waves, Ma Yumei, the Hejin Gui, field, area, 2001. Hangzhou such as Tian Fuzhen ocean rice leaf roller is to the taxis of the female pheromone of different component. Scientia Agricultura Sinica, 34 (5): 465-468)
Ningbo button health biotech company produces lure core with " along 11-vaccenic acid aldehyde, along 13-vaccenic acid aldehyde, suitable, 11-vaccenic acid pure and mild along the 13-oleyl alcohol with 60 μ g: 500 μ g: 60 μ g: 120 μ g " to lure the collection effect of core serve as the best at present in preparation.The experiment that Er Feng village, Haining City Ding Qiao town carries out in Zhejiang Province shows: 9 kinds lure core to lure 3 basin average cumulative of collection amount to lure the collection amount in the accumulative total of (15 days-September 20 August in 2009) 37d is 77.42; Lure the collection effect best be to lure core CM2009883; Its 37d accumulative total lures the collection amount to reach 207; It is 5.60/ basin every night on average that simple computation draws, and lures the collection amount not high.(come from: Yao Shitong, Wu Jiangxing, Zheng Yongli, golden Zhou Hao, Lu Zhijie, Hu Jiajun, the application of the equal .2011. rice leaf roller of Du Yong sex pheromone on its population monitoring. insect journal 2011,54 (4): 490-494.)
