under laboratory conditions, the spiny bollworm, Earias insulana (Boisd.) adult stage field strain was exposed to two magnetic fields (28.6 & 2.21 mt) and temperature levels (30 & 18oC) to study some aspects of the pest acts in biological, life table, morphological and biochemical assays as affected by the treatments used. Data obtained of E. insulana adult female biological aspects revealed that increase in the preoviposition period in the most treatments used as well as postoviposition period; vice versa happened with oviposition period. The same trend found in adult female longevity that increasing in the most treatments and contrary in male adult longevity. Eggs laying of treated adult female had severed reduction especially in high magnetic field and high-temperature treatments as well as fertility and fecundity. First-generation of treated adults affected by increasing in larval and pupal duration, reduction and mortalities as well as the pre-oviposition period in the most treatments. Also, the life table parameters of E. insulana affected by the magnetic field and temperature treatments. Female progeny/female (Mx), survival rate (Lx), net reproductive rate (Ro), intrinsic rate of natural increase (rm), finite rate of increase (erm) and sex ratio had decreased in the most treatments. The contrary was happened with generation time (T) and doubling time (DT) that had increased in the most treatments compared to control. All biochemical determinations of E. insulana adult had a reduction of total protein, free amino acids, total lipid, total carbohydrate, Alanine aminotransferase (ALT/GPT), Aspartate aminotransferase (AST/GOT) and phenoloxidase that reflects to depress malformations in different stages especially in temperature at level 30oC. From all previous, the high magnetic field and temperature were more effects on E. insulana adults than low magnetic field and temperature.
