The alfalfa pollination by Odontothrips lati was studied with 4 treatments (pesticide application + Odontothrips lati introduced+closure,pesticide application+no Odontothrips lati+isolation,no pesticide+ closure,no pesticide+no closure) in alfalfa field. The result indicated that the pod number and the seed yield under Treatment 4 (no pesticide+no isolation,alfalfa field was open) were higher (340. 33 pods/10 branches and 0. 709 1 g/10 branches). The next was treatment 1 (pesticide application+Odontothrips lati introduced + closure) and its pod number and seed yield were 57. 67 pods/10 branches and 0.175 7 g/10 branches respectively, which were 16. 95% and 24. 78% of treatment 4. The result suggest that Odontothrips lati had certain pollination to alfalfa,but its pollination efficiency was very low.
