The seasonal emergence patterns of Hylobius radicis, H. pales and Pachylobius picivorus infesting Pinus sylvestris trees in Wisconsin were determined in 1986. The pests emerged in the following sequence: H. radicis (mean emergence date 12 July), H. pales (6 August) and P. picivorus (14 September). The sex ratio for each species was 1:1, but the distribution of emerging adults per tree varied with species. Usually only one adult of H. radicis emerged per tree, whereas the distribution of H. pales was much more clustered (6.82 adults/tree). Brood production within a site was directly related to elevation along a slope. This was probably caused by differential exposure to flooding. All 3 species can breed and develop successfully in the same tree concurrently, and there was no evidence of competition between the primary species, H. radicis, and the secondary species. Co-occurrence generally facilitated development of the various species, suggesting that moderate-sized trees killed by H. radicis may provide a reservoir for development by H. pales and P. picivorus, which could then damage seedlings by adult feeding. Experiments with pitfall traps baited with ethanol plus turpentine confirmed that only overwintered adults respond to olfactory cues. |
