“…This fungus is particularly common where fire has consumed all the humus (Baylis et al 1986). Rhizina undulata has not caused problems to date after underburning, or after burning c1earcut logging debris as long as the humus layer is not consumed, which suggests that high-intensity fires are necessary to create conditions favorable for the root rot (Baylis et al 1986). Observations by De Ronde in the Cape forest regions support this hypothesis.…”

“…In industrial pine plantations in the Cape Province/South Africa, the main cause appears to be Rhizina undulata, which attacks the remaining live roots and is then followed by bark beetles (Ips) and cerambycid beetles which finish the job. This fungus is particularly common where fire has consumed all the humus (Baylis et al 1986). Rhizina undulata has not caused problems to date after underburning, or after burning c1earcut logging debris as long as the humus layer is not consumed, which suggests that high-intensity fires are necessary to create conditions favorable for the root rot (Baylis et al 1986).…”

“…Klipkraal (Mpumalanga) was one exception, with low beetle diversity in 2008, which was largely dominated by O. erosus individuals. This plantation suffered light fire in 2007 and baboon damage soon after, weakening the trees and likely facilitating the attack by O. erosus in 2008 (Baylis et al , 1986). The reason for the beetle's absence from this site in 2009 is unclear, unless local resources had been depleted.…”

Traps designed to capture insects during normal movement/dispersal, or via attraction to non-specific (plant) volatile lures, yield by-catch that carries valuable information about patterns of community diversity and composition. In order to identify potential native/introduced pests and detect predictors of colonization of non-native pines, we examined beetle assemblages captured in intercept panel traps baited with kairomone lures used during a national monitoring of the woodwasp, Sirex noctilio, in Southern Africa. We identified 50 families and 436 morphospecies of beetles from nine sites sampled in both 2008 and 2009 and six areas in 2007 (trap catch pooled by region) across a latitudinal and elevational gradient. The most diverse groups were mainly those strongly associated with trees, known to include damaging pests. While native species dominated the samples in terms of richness, the dominant species was the introduced bark beetle Orthotomicus erosus (Curculionidae: Scolytinae) (22 ± 34 individuals/site). Four Scolytinae species without previous records in South Africa, namely Coccotrypes niger, Hypocryphalus robustus (formerly Hypocryphalus mangiferae), Hypothenemus birmanus and Xyleborus perforans, were captured in low abundances. Communities showed temporal stability within sites and strong biogeographic patterns across the landscape. The strongest single predictors of community composition were potential evaporation, latitude and maximum relative humidity, while the strongest multifactor model contained elevation, potential evaporation and maximum relative humidity. Temperature, land use variables and distance to natural areas did not significantly correlate with community composition. Non-phytophagous beetles were also captured and were highly diverse (32 families) perhaps representing important beneficial insects.

“…Although O. erosus is not a tree-killing bark beetle under normal circumstances, it has demonstrated the capacity to kill trees following disturbances. These have included forest thinning followed by drought in Israel (Halperin et al 1983;Mendel and Halperin 1982); forest thinning alone in Israel (Mendel et al 1992); and fire in South Africa (Baylis et al 1986). Bevan (1984) also provides anecdotal evidence of the reaction of populations of O. erosus to various pre-disposing factors in Swaziland; Zwolinski et al (1995) suggest that in South Africa, O. erosus has a higher rate of infestation in pines that were previously wounded by hail and infected with fungi through the wounds.…”
