Emergence of the Nut Curculio, Conotrachelus hicoriae (Schoof), at Two Pecan Orchards in Louisiana

A study was initiated in commercial pecan orchards located near Monroe and Natchitoches, LA, to determine the emergence pattern of the adult nut curculio, Conotrachelus hicoriae Schoof, from hibernation. The duration of emergence was found to be approximately 75 d, with initial emergence beginning as early as 18 May. No statistically significant differences were observed in the number of adults trapped between trees and sites; however, statistically significant differences in the number of adults trapped from year-to-year were observed. The wire cone traps proved to be effective in capturing the adults emerging from the soil.
