Circle traps a useful tool in pecan weevil management

The objective of this study was to determine the average percentage of ground-emerging adult pecan weevils caught in Circle traps placed on trunks. This knowledge is essential for estimating numbers of weevils infesting pecan trees prior to management decisions (Mount, 2014). Previous research by Raney and Eikenbary (1968), Mulder et al. (2003), and Cottrell and...

Percent weevil damage related to native nut density

Previously, I reported that pecan weevil, Curculio caryae (Horn) (Coleoptera: Curculionidae), growth rates were correlated with a density dependent factor, pecan nuts per adult female weevil (Mount 2013). This relationship suggested that nuts per female weevil would also be related to larval infestations in nuts. Thus, I used nut density data from the previous report,...

Weevil management strategy important in native pecans

Growers of native pecans are well aware of the need to manage the pecan weevil (Coleoptera: Curculionidae) for prevention of unacceptable infestations of weevil larvae in harvested nuts. Previously, I reported on the dynamics of pecan weevil populations in the Mount orchard of 300 acres of non-irrigated river-bottom populated with about 3,000 native pecan trees...
