| Abstract: | The methods of comparative frequency distribution were employed to measure the spatial distribution pattern of parasitoids of Psyttalia incisi(Silvestri) in Fujian Province.The results show that the parasitoids obey the Mosaic distribution.The spatial distribution pattern was measured by the indexes of aggregation and Iwao's regression analysis.The results show that the spatial distribution pattern was also aggregating with individual exclusive,but the aggregation did not rely on the increase of population density of P.incisi.This aggregation is possibly related to the aggregation of oriental fruit flies in infested fruits.Meanwhile,the optimal theoretical sampling number and sequential sampling number were also calculated and analyzed. |
