“…Entomopathogenic nematodes have also been tested for the control of some other Euzophera species. S. carpocapsae provided satisfactory control of the persimmon bark borer, Euzophera batangensis Caradja (Hajek and Bauer 2007). In contrast, field trials to suppress the American plum borer E. semifuneralis in stone fruit trees did not provide any significant control by S. feltiae or Heterorhabditis bacteriophora Poinar (Lacey and Shapiro-Ilan 2003).…”

“…These findings, as well as those from previous studies Bauer 2006, 2008), suggest B. bassiana strain GHA has potential for managing A. planipennis in the field. The use of insect pathogenic fungi for controlling destructive wood-boring insects is not without precedent, with their success resulting from their high infectivity, virulence, diversity, and a moist environment inside trees (Hajek and Bauer 2007). We suggest continued and expanded research on B. bassiana strain GHA for control of A. planipennis, by evaluating its efficacy in larger field trials, such as treatment of large ash trees in parks and forests, as well as ash trees beyond the ash-removal zones during eradication efforts at outlier infestations.…”

The effects of Beauveria bassiana strain GHA, applied as BotaniGard ES, on newly colonised and well-established populations of emerald ash borer, Agrilus planipennis (Coleoptera: Buprestidae) were evaluated in the field using foliar and trunk sprays in Michigan in 2004Á2005. Results from field trials at a newly colonised white ash site showed a 41% reduction in A. planipennis population in fungal-treated trees compared with that of untreated controls. In addition, fungal infection was also found in 20% of the larval population within 14 days of incubation under laboratory conditions. At a site with a well-established A. planipennis population in green ash trees, larval density was reduced by 47% for trees treated with the fungus compared with that of the controls; 21% of larvae from the current generation were found infected after 14 days of laboratory incubation. Fungal-treated green ash trees also produced fewer adults emerging in the next generation, with a 63% reduction in adult density observed in treated trees compared to that of controls. As a result, fungal-treated trees sustained 42% less crown dieback than did controls. Agrilus planipennis larval density was negatively correlated with trunk height above the ground, and positively correlated with log diameter. Results of laboratory leaf bioassays on A. planipennis adults showed that fungal conidia persisted well under field conditions, with mortality of 78Á100% at 7-days post-exposure for leaves collected between 2 and 264 h after application. Potential strategies for using B. bassiana strain GHA for managing A. planipennis are discussed.

“…Factors influencing the presence of C. undatus are tree density, presence of understory, age, health and height of trees, solar orientation and drought stress [16]. Like in the case of other borers, the control of C. undatus is difficult to perform because the larva (damaging stage) is endophytic, undetectable and practically inaccessible [17,18]. In Andalusia (southern Iberian Peninsula), several studies have been carried out on the environmental variables that influence the incidence of C. undatus.…”

This work assesses damage caused by Coraebus undatus (Fabricius) (Coleoptera: Buprestidae) and Reticulitermes grassei Clément (Blattodea: Rhinotermitidae) in managed cork oak forests from the southern Iberian Peninsula. Lesions were diagnosed and quantified in relation to the following features: height and orientation in the trunk, diameter at breast height, solar exposure, understory presence and orography. The distribution patterns of lesions in the study area across 12 plots and in the trunk of the trees were also analyzed. The study was performed in “Sa de Hornachuelos” Natural Park (Córdoba, Spain) and the research area encompassed 12 environmentally-restored sampling plots. Data were recorded from 2007 to 2014, with yearly sampling from late June to mid-September, corresponding to the cork extraction period, since lesions caused by these insects are well distinguishable promptly after bark removal. The results reveal that C. undatus has low population levels and a non-uniform distribution pattern in the study area as well as in the trunk of the tree. It shows preference for medium height but not by any trunk orientation. R. grassei also shows low infestation levels and a preference to affect the trunk’s base. Comparatively, C. undatus showed higher infestation levels than R. grassei. The location of damage was also different, since galleries made by C. undatus predominated at intermediate trunk heights while those of R. grassei were more frequent at lower heights. Our results further showed a low co-occurrence of both species in the same tree trunks, which could be explained in terms of overlapping in the distribution areas of both species. These results provide background information that will enable natural resources managers to detect changes and trends of these species and inform future management decisions.
