| Abstract | ||||
| Mortality of adults and larvae of the stored product mite, Tyrophagus putrescentiae infested flour or wheat bran exposed to microwave radiation (2450 MHZ) was evaluated as a function of exposure time and power. Mortality experiments were conducted at exposure times 60-300 sec at power level of 110 W and from 10 to 90 sec at 330 and 550 W. Adult and larva mortalities were higher in flour with 12.5% moisture content (m.c.) than in wheat bran with 8.5 % m.c. The minimum average temperature (27.8 ºC) was recorded in wheat bran at 330 W for 10 sec, whereas the maximum average was 60.5ºC in flour at 550 W for 90 sec. Complete mortality of larvae and adults of T. putrescentiae was obtained at 45 and 46.6 ºC, respectively. T. putrescentiae larvae presented a mortality rate higher than adults when exposed to the same Mw energy radiation. | ||||
