在墨西哥恰帕斯州Soconusco不同海拔高度（海拔450 ~ 1100 m）的三个咖啡农场，研究了3株球孢白僵菌（Balsamo） Vuillemin)和2株绿僵菌（Metschnikoff） Sorokin对咖啡浆果螟hampei （Ferrari）的影响。真菌病的最大平均百分比因海拔而异。在海拔450米（El Rincon），球孢白僵菌和绿僵菌的感染率分别为14.3%和6.3%；在海拔880 m的圣安妮塔地区，球孢白僵菌和绿僵菌分别为40.6%和12.6%；在海拔1100 m的阿尔普贾拉斯地区，球孢白僵菌和绿僵菌分别为33.9%和22.1%。不同菌种间真菌感染的时间差异不显著（P < 0.01），但不同菌种间真菌感染的时间差异显著（P < 0.01）；低海拔最佳菌株为Bb25和Ma4，中海拔最佳菌株为Bb26和Ma4，高海拔最佳菌株为Bb26和Ma4。温度、相对湿度和降雨等环境因子与球孢白僵菌和金龟子白僵菌致病菌比例无关。而球孢白僵菌侵染水平与真菌侵染反应呈显著正相关（P < 0.01）。
The effect of three strains of the fungus Beauveria bassiana (Balsamo) Vuillemin and two strains of Metarhizium anisopliae (Metschnikoff) Sorokin upon the coffee berry borer, Hypothenemus hampei (Ferrari),was studied in three coffee farms at different altitudes (450-1,100 m above sealevel) in Soconusco, Chiapas, Mexico. The maximum average percentage mycosis varied according to altitude. At 450 m asl (El Rincon) mycosis was 14.3% for B. bassiana and 6.3% for M. anisopliae; at 880 m asl (Santa Anita) mycosis was 40.6% for B. bassiana and 12.6% for M. anisopliae, and at 1,100 m asl (Alpujarras) 33.9% for B. bassiana and 22.1% for M. anisopliae. The effect of fungal mycosis through time was not significant (P > 0.01) in any of the farms, but there was a significant difference between the strains of the fungus (P < 0.01); the best strains being Bb25 and Ma4 at the lower altitude, Bb26 and Ma4 for the middle altitude and Bb26 and Ma4: at the higher altitude. Environmental factors such as temperature, relative humidity and rain were not correlated with the percentage mycosis caused by B. bassiana and M. anisopliae. However, in the case of B. bassiana there was a significant, positive correlation (P < 0.01) between the infestation levels of the pest and the mycosis response of the entomopathogen.
