The biology of Laemophloeus ferrugineus (Steph.).

摘要: Life history and morphological studies were made on Laemophloeus ferrugineus (Steph.), a coleopterous pest of stored grain other products.Temperature greatly affected the rate development L. ferrugineus. At relative humidity 75%, eggs at 80° F. hatched in four to five days, 90° three 100° two days. Similarly, period from hatching egg emergence imago 70° was 69 103 26 38 90°F. 19 33 17 First instar larvae did not survive temperature 110° F.An increase within range 50 75% accelerated during larval feeding period. Above there no significant acceleration development. Mortality very high humidities below 50%—all failing develop 25%. o...
