摘要

Japan has phytosanitary and quarantine measures that stipulate that hay shipments should be inspected for host plants or disinfested of Hessian fly (Mayetiola destructor (Say)) puparia. Canadian processors would prefer disinfesting the hay before shipping since it is more viable and economical than the inspection method. Field tests were conducted in the summer of 2007 to investigate the effect of different compression pressures, storage time and hay properties on the disinfestation of Hessian fly puparia. Four different timothy hay lots (first-cut hay at low moisture content (MJ, first-cut hay at high moisture content (M_2), second-cut hay at low moisture content (M3), and second-cut hay at high moisture content (M_4) were compressed (re-baled) attwo pressures of 10.34 and 12.41 MPa. The bales were stored for 0.5 h, 24 h, 168 h (1 week), 336 h (2 weeks), and 504 h (3 weeks). For storage times 168, 336 and 504 h, the compressed bales were stored in a container to simulate storage and shipping conditions. Four puparia survived to adulthood in the bales stored for 0.5 h and 24 h and compressed at low pressure of 10.3 MPa. However, there was no survival in any of the high pressure (12.4 MPa) treatments or in the bales stored for 168 h (1week), 336 h(2 weeks), and 504 h (3 weeks) treated at lower compression pressure (10.3 MPa). This result also proves that bales remaining compressed (straps not removed) during the length of time it takes to ship them from Canada to Japan is effective in disinfesting Hessian fly. The hay characteristics had no effect on the disinfestation since the emergence of Hessian flies were found both in high moisture content bales and in low moisture content bales, and in first cut and second cut hay as well.
