| Abstract: | In the field surveys conducted during 1983 1989,eight species of parasitic wasp s were found attacking the Asian corn borer(ACB)in cotton fields in the coastal grain a nd cotton growing areas of Jiangsu Province.A braconid, Macrocentrus linearis was found to be the predominant species.The occurrence of the ACB population p e ak was delayed for 2 5 days due to high parasitization rate by the braconid par asitoid.Crop damage by ACB was also reduced. |
