The Spatial Pattern of Bactrocera dorsalis Males with Geostatistics

More Information
  • Received Date: January 25, 2005
  • Spatial pattern of oriental fruit fly Bactrocera dorsalis(Hendel) males was studied in the guava orchard by using geostatistical method.Methyl eugenol was used to attract the males in the sample.The semiviariograms were described at the two directions of east-west and south-north.The results showed that the semivatiograms of B.dorsalis was described by a spherical model and an exponential model,and indicated a spatial pattern ranging from 292.0 to(920.2) m with a spherical model and from 447.6 to(1 567.8 m) with an exponential model in the north-south.The spherical model showed nugget in the east-west.The exponential model indicated a spatial pattern ranging from 770.4 to(2 514.6 m) during from 18~(th) to 30~(th) July,but it indicated nugget in 14~(th) July.
