Size distribution and shape factor of magnetic particles calculated from the transmission electron micrographs in nymphs of BPH, Nilaparvata lugens.
(a–f) size distribution and shape factor of the 3rd, 4th and 5th instar nymphs with N = 221, 234 and 258, respectively. N, total number of magnetic particles used in this calculation. Five hundred individual insects for each insect stage, sex and wing form were sampled to get the total number of particles. nd - not detected.
