Response to Magnetic Field-Induced Stress on the Demographics and anti-ROS Activity of Aphid Macrosiphum rosae L. (Hemiptera:Aphididae)

Magnetic field plays an essential role for many species, including the migratory pest aphid. Our previous study investigated long-term exposure of static magnetic fields on growth development and productivity aphid Macrosiphum rosae, however, it is necessary to expand knowledge short-term insects a wider spectrum radiation. To achieve this, nymphs were exposed four induction at 0.065T, 0.1T, 0.176T 0.28T 4min under laboratory conditions. The results showed that radiation significantly prelonged instar while shortened first, second third period. 0.28 T radiations caused difference in parameters TPOP, adult longevity total (3.2d, 7.07d, 8.82d, compared with control 4.94d, 8.06d, 10.23d, respectively). Population parameter r was 0.057d-1 0.150 d-1. SOD, CAT POD activity increased more than 30% controls. presents feasible evidence showing change as representative disturbing symptom fields, applied being capable modifying fitness components antioxidant defense aphids.
