MAGNETIC FIELD AND INSECTICIDE INTERACTIONS FOR LETHAL ALTERED TOXIC ACTION AND STUDY OF NEGATIVE IMPACT ON EARIAS INSULANA (BOISD.) (LEPIDOPTERA: NOLIDAE)

The purpose from current experiment was to increase the activity of insecticides after exposure to magnetic power field (increased in toxicity with able to kill the pest insect by low dose). Earias insulana (Lepidoptera: Nolida) insect behavior and physiology have been shown to be affected by both tested compounds (Uphold and Tracer) before and after exposed to magnetic fields. We're curious about the effects of compounds magnetization on Earias insulana larvae. The goal of this study was to better understand the interaction between magnetic field (180 mlt for 1 hour) and two insecticides, Uphold and Tracer, in order to quantify the increase of their lethal toxicity after exposure. Two insecticides were tested for toxicity against E. insulana 2nd, 3rd, and 4th instar larvae, as well as their effects on larvae and pupae stages. According to the data, the LC50 values for Uphold and Tracer were 0.582, 0.690, 1.022 and 4.949, 9.356, 13.753 ppm respectively, while, after magnetization of the same insecticides the LC50 values for Uphold and Tracer were 0.331, 0.607, 0.859 and 3.823, 7.779, 10.590 ppm respectively. After magnetization some enzymes and biochemical contents have changed. AchE and Alk-Ph increased significantly, while, total proteins and free amino acids decreased significantly.
