温度对黄瓜钝绥螨发育历期的影响

With Polyphagotarsonemus latus as its prey, the developmental duration of Amblyseius cucumeris was 13.02, 9.61, 5.96, 5.26, 4.65, 4.78, and 5.80 days at 18, 20, 23, 25, 28, 30, and 31 degrees C, respectively. The eggs of A. cucumeris could not hatch at 32 degrees C. The lower and upper developmental thresholds and the optimum developmental temperature of A. cucumeris from eggs to adults were 12.77 degrees C, 33.50 degrees C and 23.87 degrees C, respectively.
